    ملاحظات مهمة جداً

    - هذا الملف يتضمن تقريباً كل الأسئلة الواردة في الموقع من بدايته حتى الصفحة 142.
    - يمكن للزملاء المناقشة والتعديل ويفضل مع مرجع.
    - اعتمدت أولاً على الإجابات والمناقشات والمراجع التي استعان بها الزملاء والزميلات (مشكورين فرداً فرداً)
    - اعتمدت ثانياً على المراجع المطلوبة من الهيئة وأمهات كتب طب الأسنان بالإضافة لمنشورات الجامعات السورية.
    - من هذه المراجع:
    - Dental decks2 – Dental Secrets - Oxford Handbook of Clinical Dentistry, 4th Edition الأهم :
    - - Art and science of operative dentistry 2000 - Atlas Of Oral Medicine - Caranza periodontology - PDQ Oral Disease Dx Tx 2002 - Pathway of the pulp 9ed 1st – Contemporary Fixed Prosthodontics - Wikipedia
    كتب: التعويضات المتحركة الكاملة 2006 - طب أسنان الأطفال - أمراض الفم، وغيرها..

    - لا ضير من استخدام اللغة العربية في ترجمة بعض الكلمات وأنا أفضل ذلك على كتابة جملة بأكملها بلفظها الأجنبي وبحروف عربية!
    - ترقيم الأسئلة غير منتظم لأنها من مصادر وصفحات متعددة من الموقع ، وكذلك تعمدت -ما أمكنني- وضع الأسئلة والمواضيع المتشابهة بجانب بعضها.
    - الجواب الأكيد باللون الأخضر وبجانبه 3 نجمات ***.
    - الجواب الذي عليه إجماع دون مرجع باللون الأخضر فقط، وإن أمكن يفضل تقديم مرجع أو نص.
    - الجواب الذي عليه خلاف ولم يتم الإجماع عليه، محاط باللون الأصفر وهو متروك لمشاركة الزملاء المعتادة، وإن أمكن يفضل تقديم مرجع أو نص.
    - الجواب باللون الأخضر والمحاط بلون أصفر يعني أنه جواب ممكن من وجهة نظري رغم وجود جواب آخر ويفضل أن يناقش أو يفنّد.
    - الإجابات تتناسب مع الأسئلة المطروحة والتي تعتمد على ذاكرة الزملاء بعد الامتحان حيث يمكن أن يكتبوه ناقصاً أو مختلفاً عن الأصل مما قد يسبب الإرباك، ولذلك تم وضع نصوص من المراجع لاختيار الأجوبة على أساسها.
    - حاولت ما أمكن تصحيح الكلمات المكتوبة بشكل خاطئ لغوياً وعلمياً ولذلك سيكون هناك اختلاف مع صيغته المكتوبة في الموقع.
    - النقاط أو الترقيمات التي بعدها فراغ تعني وجود خيار ولكن لا يمكن تذكره وغالباً ليس هو الخيار الصحيح.
    - أعتذر عن عدم الترتيب أو أي أخطاء في الإجابات فملف ضخم كهذا يحتاج جهد كبير لكل من التنسيق والتأكد من المعلومات، ويحتاج جهد جميع الزملاء.

    والأهم: الفضل في هذا العمل يعود للزملاء الذين ساعدونا بأنهم وضعوا على هذا الموقع الأسئلة التي امتحنوا بها، وللزملاء الذين جمعوا الأسئلة في ملفات كانوا يضعونها تباعاً، ولولاهم جميعاً لما كان هذا العمل المتواضع.

    آسف للإطالة ولهذه المقدمة، وأتمنى الرد والمشاركة الفاعلة من الجميع.

    تحياتي وتمنياتي للجميع بالتوفيق

    Complete Denture 17th Ed – page 16
    RESIDUAL RIDGE RELATIONSHIP: Class II or retrognathic is usually difficult as the patient looks toothy, often holds the mandible forward to improve appearance with subsequent TMJ problems, usually have a great range of jaw movements in function, require careful occlusion, and usually needs a large interocclusal distance. Class Ill or prognathic is usually easier if not extreme. The patient usually functions on a hinge (little or no protrusive component) and requires a minimum of interocclusal distance. In any case, do not set the teeth for a retrognathic or prognathic patient in a normal relationship, unless there is only a moderate deviation from Class I.

    المرجع: التعويضات المتحركة الكاملة
    الامتداد الزائد للحواف الخلفية للجهاز الفكي العلوي:
    في محاولة طبيب الأسنان الممارس لزيادة الخواص التثبيتية للجهاز فإنه قد يتجاوز فيزيولوجية الجهاز العضلي للحنك الرخو ويضع الحدود الخلفية للجهاز السني بعيداً جداً نحو الخلف، عندما يحصل ذلك فإن الجزء النشط من الحنك الرخو ينثني مقابل قاعدة الجهاز السني الصلبة وغير اللينة .
    والشكوى التي تتكرر أكثر عند المرضى هو أن البلع يكون صعباً ومؤلماً، وفي تلك الحالة يمكن مشاهدة مناطق صغيرة متقرحة في الحنك الرخو، يتم تعليم الآفة بقلم غير قابل للمحي وينقل إلى قاعدة الجهاز السني حيث تتم إزالة مكان الامتداد الزائد عن طريق السحل وبعد ذلك إعادة صقله بحذر.
    إذا كانت الشاخصات الكلابية مغطاة من قبل قاعدة الجهاز السني فإن المريض سوف يعاني من ألم حاد وخاصة أثناء الوظيفة, يجب أن لا تغطى قاعدة الجهاز الشاخصات الكلابية.

    8. Pt with denture has swallowing problem and sore throat. The problem is: حلق ملتهب
    e. Posterior over extension at distal palatal end. ***

    d. A & b are correct. ***
    المرجع : "التعويضات المتحركة الكاملة"
    " ومن المعلوم أننا إذا قمنا بإطالة الحواف أكثر من الطبيعي فإن ذلك سيؤدي إلى نتيجة سيئة لأنه يخرش المخاطية المتحركة, ويحرض منعكس الإقياء".
    الخيار الثالث لا يسبب منعكس إقياء (لأنه امتداد قليل للخلف)
    ملاحظة: يضاف لما سبق التلميع الزائد للجهاز وقلقلة الجهاز Protusive imbalance التي تسبب حركة اللعاب تحت حافته الخلفية


    10. Planning centric occlusion for complete denture, it is advisable to have:

    "التعويضات المتحركة الكاملة"
    "تتوضع الثلمة الجناحية الفكية بين الحدبة الفكية والشص الجناحي للصفيحة الأنسية للعظم الوتدي، وهي نقطة علام هامة لإنهاء حواف الجهاز عندها، وتعتبر أكثر مناطق التثبيت أهمية في الجهاز العلوي"
    "أغلبية العينات كانت لها نقرات تقع على أو خلف خط الاهتزاز الأمامي (على جانبي الخط الأوسط). لذلك فإن موقع النقرات لا يمثل الملتقى بين الحنكين الرخو والصلب . ولا يجب استعمال النقرات الحنكية كدليل على توضع السد الخلفي . إن الطبيب الذي يلاحظ هذه النقرات ويستخدم هذه المعالم التشريحية على أساس أنها حد خلفي لقاعدة الجهاز السني يمكن أن يحرم مريضه من عدة مليمترات بل حتى سنتيمتر وأكثر من مدى تغطية النسيج وذلك اعتماداً على الشكل الحنكي . وهذا بدوره سيكون له تأثير سلبي على ثبات قاعدة الجهاز السني الكامل للفك العلوي"

    13. The distal palatal termination of the maxillary complete denture base is dictated by the:
    a. Tuberosity. الحدبة الفكية
    b. Fovea palatine. نقرة الحنك

    Bases (cement bases, typically 1 to 2 mm) are used to provide thermal protection for the pulp and to supplement mechanical support for the restoration by distributing local stresses from the restoration across the underlying dentin surface. This mechanical support provides resistance against disruption of thin dentin over the pulp during amalgam condensation procedures or cementation procedures of indirect restorations.
    Liners are relatively thin layers of material used primarily to provide a barrier to protect the dentin from residual reactants diffusing out of a restoration and/or oral fluids that may penetrate leaky tooth-restoration interfaces. They also contribute initial electrical insulation; generate some thermal protection.

    Diagnosis Le Fort I may occur singly or associated with other facial fracture. The tooth-bearing portion of the upper jaw is mobile, unless impacted superiorly. There is bruising in the buccal sulcus bilaterally, disturbed occlusion, and posterior 'gagging' of the bite. Grasp the upper jaw between the thumb and forefinger anteriorly, place thumb and forefinger of other hand over the supraorbital ridges, and attempt to mobilize the upper jaw to assess mobility. Spring the maxillary teeth to detect a palatal split. Percussion of the upper teeth may produce a 'cracked cup' sound. Le Fort II and III fracture produce similar clinical appearances; namely, gross oedema of soft tissues, bilateral black eyes (panda facies), subconjunctival haemorrhage, mobile mid-face, dish-face appearance, and extensive bruising of the soft palate. Look for a CSF leak and assess visual acuity. Le Fort II fracture may also show infra-orbital nerve paraesthesia and step deformity in the orbital rim. Peculiar to Le Fort III fracture are tenderness and separation of the frontozygomatic suture, deformity of zygomatic arches bilaterally, and mobility of entire facial skeleton.

    The eyes are examined for double vision (diplopia), any restriction of movement and subconjunctival haemorrhage. The condyles of the mandible are palpated and movements of the mandible checked. Swelling, bruising and lacerations are noted together with any areas of altered sensation that may have resulted because of damage to branches of the trigeminal nerve. Any evidence of cerebrospinal fluid leaking from the nose or ears is noted, as this is an important feature of a fracture of the base of the skull. An intra-oral examination is then carried out, looking particularly for alterations to the occlusion, a step in the occlusion, fractured or displaced teeth, lacerations and bruises. The stability of the maxilla is checked by bimanual palpation, one hand attempting to mobilise the maxilla by grasping it from an intra-oral approach, and the other noting any movement at extra-oral sites such as nasal, zygomatic-frontal and infraorbital.

    Clinical Aspects of Dental Materials Theory, Practice, and Cases (3rd Ed 2009)
    The strength and other physical properties, EXCEPT wear resistance and surface roughness, of macrofilled composites are adequate for Class III, IV, and V restorations. Excessive wear when used for Class I and II restorations limited their posterior use. Macrofills were used before dentinal bonding systems were developed; placing them in posterior teeth resulted in postoperative sensitivity, leakage, and recurrent decay.
    The problem with microfilled composites is the low percentage filler (40–50%). The surface area of the very small filler particles requires much more resin to wet the surface of the filler particles. This high resin content results in an increased coefficient of thermal expansion and lower strength.
    Microfilled composites were used when esthetics are the dominant concern. Large composite restorations, such as an extensive Class IV restoration, are built in layers of several different shades and translucencies. The first layers to be placed are a hybrid composite selected for strength. The final layer, a veneer of sorts, is a microfilled composite selected for surface luster.
    Microfilled composites are also used in Class V restorations at the cemento–enamel junction. Microfills have a lower modulus of elasticity and flex with the tooth better than the strongest composite materials. Clinical research has shown Class V microfill composite restorations are more likely to be retained than other composite materials.
    Hybrid composites are very popular; their strength and abrasion resistance are acceptable for small to medium Class I and II restorations. Their surface finish is nearly as good as that of microfills; thus, they are also used for Class III and IV restorations.

    Epithelial cell rests of Malassez - Wikipedia, the free encyclopedia
    In dentistry, the epithelial cell rests of Malassez or epithelial rests of Malassez (frequently abbreviated as ERM) are part of the periodontal ligament cells around a tooth. They are discrete clusters of residual cells from Hertwig's epithelial root sheath (HERS) that didn't completely disappear. It is considered that these cell rests proliferate to form epithelial lining of variousodontogenic cysts such as radicular cyst under the influence of various stimuli. They are named after Louis-Charles Malassez (1842–1909) who described them. Some rests become calcified in the periodontal ligament(cementicles)

    19. What is the difference between a lateral radicular cyst and a lateral
    periodontal cyst?
    A lateral radicular cyst is an inflammatory cyst in which the epithelium is
    derived from rests of Malassez (like a periapical or apical radicular cyst). It is-in a
    lateral rather than an apical location because the inflammatory stimulus is
    emanating from a lateral canal. The associated tooth is always nonvital. The
    lateral periondontal cyst is a developmental cyst in which the epithelium
    probably is derived from rests of dental lamina. It is usually located between the
    mandibular premolars, which are vital.

    Vertical Fracture
    A vertical fracture of a tooth may result in communication between the gingival sulcus (oral cavity) and the apical periodontium. The fracture line will be a portal of entry for bacteria from the mouth into the tissues, causing inflammation and bone destruction. A periapical lesion often forms which may have the appearance radiographically of a pulpally related lesion. Since a vertical fracture may be incomplete, its diagnosis in many instances is extremely difficult. Sometimes it is recognized clinically because a periodontal pocket forms along the fracture line and in other instances a simple exploratory surgical procedure may aid in establishing the correct diagnosis.

    Clinical appearance Most often seen as a painless ulcer, although may present as a swelling, an area of leukoplakia, erythroleukoplakia or erythroplakia (A reddened patch), or as malignant change of long-standing benign tumours or rarely in cyst linings. Pain is usually a late feature when the lesion becomes superinfected or during eating of spicy foods. Referred otalgia is a common manifestation of pain from oral cancer. The ulcer is described as firm with raised edges, with an indurated, inflamed, granular base and is fixed to surrounding tissues.

    This situation is often referred to as a “weeping canal” and is annoying in that the apical part of the canal cannot be dried properly. The right therapy is a discontinuation of the use of the tissue-irritating antiseptics followed by 2–3 weeks of calcium hydroxide in the root canal. The chemically-induced exudation will then have stopped and the root canal can be dried and obturated.

    The diagnosis of cusp fracture is easy when the cusp has fallen off. Before this actually happens, however, the patient may experience pain but often finds it remarkably difficult to locate this to a particular tooth. The patient will frequently complain of sensitivity to hot and cold and discomfort on biting. Even on clinical examination it is often difficult to pinpoint which tooth is causing the pain, but a fiber-optic light or disclosing solution may assist the diagnosis by making the crack easier to see. Lateral pressure on the suspect cusp may also help by producing a sensitivity that mirrors the patient’s symptoms. Often the pain occurs when the pressure is released.

    A crack usually does not show up on an x-ray, a physical examination of the tooth will have to be performed. A sharp instrument will be used to allow us to explore the tooth for cracks. We will also place pressure on the tooth to see if we can expand the crack until it is seen.
    You may have X-rays taken but X-rays often do not reveal the crack.
    Your dentist may use a special tool to test the tooth. There are different kinds of tools. One looks like a toothbrush without bristles. It fits over one part of the tooth at a time as you bite down. If you feel pain, the part of the tooth being tested most likely has a crack in it.

    Diagnostic tests of cracked tooth
    visual examination of cracks: aided by staining with dye such as methylene blue.
    Tactile examination crutch the tooth surface with a sharp explorer widening a gap of the crack may elicit extremely painful response. أي بمثابة ضغط أفقي

    In the absence of a ferrule, Aykent et al19 found that in vitro use of a dentine bonding agent with an amalgam core and a direct stainless steel post provided a significant increase in fracture resistance in extracted premolars. Whilst dentine bonding of the amalgam core did not offer any significant improvement when a 1 mm ferrule was present, this study suggests that there may be a role for dentine bonding of amalgam cores when a ferrule cannot be achieved.
    Both crown lengthening and orthodontic extrusion may allow for an increased ferrule, but they add additional cost, discomfort and length of treatment times for the patient. Crown lengthening increases the crown to root ratio. Whilst Ichim et al16 used finite element analysis to predict that crown lengthening did not alter the levels or pattern of stress within the palatal dentine, Gegauff20 concluded that crown lengthening could be problematic.
    Gegauff20 investigated whether crown lengthening to achieve a ferrule would affect the static load failure. By placing the finish line further apically, Gegauff postulated that the tooth may be weakened as a result of the resultant decrease in cross-sectional area of the preparation and the increased crown to root ratio. Orthodontic extrusion may avoid this problem as it results in a smaller change in the crown to root ratio.

    رأي المريض هو الأهم في اختيار لون الأسنان الصناعية مع تدوين رأي الطبيب
    وحسب كتاب "التعويضات المتحركة الكاملة"
    وعندما نبدأ بانتقاء اللون يجب على الطبيب استبعاد الألوان شديدة البياض لأن بعض المرضى يستهويهم اللون الأبيض الناصع فنحصل على نتائج مخزية في نهاية العلاج . ويكتفي الطبيب باختبار طيف غير واسع من الألوان بحيث تكون كلها مقبولة ويعرضها بعد ذلك على المريض ليساهم بالاختيار، وإذا ما رفض المساهمة بالاختيار، نصر على مشاركته حتى ولو اختار بين لونين أو ثلاثة ليشعر في النهاية أنه مساهم ومسؤول مثله مثل الطبيب عن النتائج الجمالية للعلاج .
    إن رضى المريض والطبيب معاً وتسوية الأمور بشكل وسطي غالباً يعتبر أفضل الحلول ويجب عند ذلك أن يكون الطبيب والمريض في حالة ارتياح ورضى تجاه القرار النهائي وإلا فإن النتائج النهائية للمعالجة ستكون في خطر وإذا ما كان المريض متصلباً في آرائه ولم يستطع الطبيب إقناعه أو إيصاله إلى الاختيار الصحيح فسيكون اللجوء إلى طبيب آخر أو عدم متابعة المعالجة أمراً متوقعاً .

    Mucocele
    Infrequently, a mucocele goes away without treatment. But if some mucoceles remain untreated, they can scar over. Your dentist should examine any swelling in your mouth.
    A mucocele usually is removed by surgery. The dentist may use a scalpel or a laser to remove the mucocele. Afterward, the tissue will be sent to a laboratory for evaluation. There is a chance that after the mucocele is removed another one may develop.
    Some doctors use corticosteroid injections before trying surgery. These sometimes bring down the swelling. If these work, you may not need surgery

    Anatomy of the Human Body - Henry Gray – page 27
    - The mandibular arch lies between the first branchial groove and the stomodeum; from it are developed the lower lip, the mandible, the muscles of mastication, and the anterior part of the tongue.
    - The ventral ends of the second and third arches unite with those of the opposite side, and form a transverse band, from which the body of the hyoid bone and the posterior part of the tongue are developed.
    Anatomy of the Human Body - Henry Gray – page 693
    During the third week there appears, immediately behind the ventral ends of the two halves of the mandibular arch, a rounded swelling named the tuberculum impar, which was described by His as undergoing enlargement to form the buccal part of the tongue. More recent researches, however, show that this part of the tongue is mainly, if not entirely, developed from a pair of lateral swellings which rise from the inner surface of the mandibular arch and meet in the middle line.

    298. To prevent gingival injury place the margin of the retainer:
    A. At the level of gingival crest. ***
    b. Above gingival crest.
    C. Apical to g . Crest 1 mm
    d. Apical to g. Crest 0.5 mm.

    Dental secrets – page 219
    It is better for gingival health to place a crown margin supragingivally, 1—2 mm above the gingival crest, or equigingivally at the gingival crest. Such positioning is quite often not possible because of esthetic or caries considerations. Subsequently, the margin must be placed subgingivally. Margin ends slightly below the gingival crest, in the middle of the sulcular depth, or at the base of the sulcus. In preparing a subgingival margin, the major concern is not to extend the preparation into the attachment apparatus. If the margin gf the subsequent crown is extended into the attachment apparatus, a constant gingival irritant has been constructed. Therefore, for clinical simplicity, when a margin is to be placed subgingivally. It is desirable to end the tooth preparation slightly below the gingival crest.

    c) Ultrasonic tips

    A grasping tool such as the Stieglitz pliers (Henry Schein) can generally get a strong purchase on the coronal end of a silver point and then, utilizing the concept of fulcrum mechanics, elevate the silver point out of the canal.
    Indirect ultrasonics is another important method to remove silver points. It is not wise to place any ultrasonic instrument directly on the silver point because it will rapidly erode away this soft material.
    And
    Endodontics Problem solving in clinical practice 2002 – page 142
    Cement can be removed carefully from around the point using a Piezon ultrasonic unit and CT4 tip or sealer tip. Great care must be taken not to sever the point and damage the coronal end. The point is withdrawn using Stieglitz forceps or small-ended artery forceps.

    In order to prevent discoloration of the tooth crown by components of the root canal filling material, a heated instrument must be used to sever the filling material 2mm apical to the cementoenamel junction.
    Pocket Atlas of Endodontics – page 88
    It must be sufficiently extended mesially and distally so that the pulp horns can be completely accessed and all necrotic tissue removed. Tissues that are left behind can lead later on to discoloration of the clinical crown.

    Q- When removing moist carious dentin which exposes the pulp, dentist should:
    1- do direct pulp cap
    2- do indirect pulp cap
    3- prepare for endo. ***

    "Dental secrets – page 167"
    There is general agreement that carious exposure of a mature permanent tooth generally requires endodontic therapy. Carious exposure generally implies bacterial invasion of the pulp, with toxic products involving much of the pulp.
    However, partial pulpotomy and pulp capping of a carious exposure in a tooth with an immature apex have a higher chance of working.

    "Dental pulp 2002 – page 335"
    Cavity Cleansing, Disinfection, and Hemorrage Control
    A clinical review failed to support direct pulpcapping or pulpotomy procedures in teeth when a mechanical exposure pushes infected carious operative debris into the subjacent pulp. Because of the stigma of long-term failures, our profession generally selects traditional endodontic treatment. Only in the treatment of pulp exposures in fractured young anterior teeth with open apices does the literature discuss pulpotomy or direct pulp-capping with Ca(OH)2.

    Anaphylaxis is always an emergency. It requires an immediate injection of 0.1 to 0.5 ml of epinephrine 1: 1,000 aqueous solution, repeated every 5 to 20 minutes as necessary.
    • If the patient is in the early stages of anaphylaxis and hasn’t yet lost consciousness and is still normotensive, give epinephrine I.M. or subcutaneously (S.C.), helping it move into the circulation faster by massaging the injection site. For severe reactions, when the patient has lost consciousness and is hypotensive, give epinephrine I.V.

    259) sharping of hand instrument mounted air driven better than unmounted due to
    A) fine grift. ***
    B) sterilization
    C) ability to curve instrument

    The mounted-stone technique. The second technique for sharpening dental instruments is the mounted-stone technique. This technique is especially useful in sharpening instruments with curved or irregularly shaped nibs. Equipment consists of mandrel-mounted stones, a straight handpiece, lubricant, two-inch by two-inch gauge, and again, the instrument to be sharpened. Mounted stones are made of two materials, Arkansas stones and ruby stones (sometimes called sandstones). Ruby stones are primarily composed of aluminum oxide. The ruby stone is comparatively coarse, has a rapid cutting ability, and is used for sharpening instruments that are dull. Mounted stones are cylindrical in shape and appear in several sizes. They have a fine grit and are used with the straight handpiece. The stones permit rapid sharpening, but without extreme care, will remove too much metal and may overheat the instrument. Overheating the instrument will destroy the temper, thereby causing the instrument to no longer hold a sharp edge.


    22) Unmounted sharpening instruments are better than mounted because:
    has finer grains
    don't alter the bevel of the instrument
    easier to sterilize
    less particles of the instruments are removed = cut less of the plade.

    Therefore, like citric-acid rinsing, EDTA solution is recommended before the placement of calcium hydroxide. At a 15% concentration, citric acid has been shown to be very effective against anaerobic bacteria.
    Solvidont, a bisdequalium acetate, exhibits good antibacterial properties, but also an unfavorable relationship between cytotoxicity and antibacterial efficiency.
    Physiologic saline (nacl) is by far the most tissue-friendly rinsing solution, but its antibacterial effect is quite low.
    Iodine and also potassium iodine are good antiseptics with equally good tissue biocompatibility.
    “Betadine” is the commercially available product.
    With paraformaldehyde or phenol-containing solutions, on the other hand, the tissue toxicityis higher than the antibacterial efficacy.

    Resting face height is assessed using:
    • A Willis gauge, to measure the distance between the base of nose and the underside of the chin. Is only accurate to ±1 mm.
    • Spring dividers, to measure the distance between a dot placed on both the chin and the tip of the patient's nose. This method is less popular with patients and is C/I for bearded gentlemen (or ladies!).
    • The patient's appearance and speech.

    In-Ceram has been used to fabricate fixed partial dentures, but the manufacturer recommends only short-span (three-unit) anterior restorations.
    Alumina-reinforced ceramic systems (In-Ceram) significantly improve the light reflection characteristics of crowns when compared to conventional metal-ceramic restorations.
    However, opaque aluminum oxide diminishes translucency when compared to leucite-reinforced systems (Optec, IPS-Empress). To improve light transmission and reflection in single anterior crowns where maximum strength is not required, a magnesium aluminous
    spinel may be utilized. The transilluminating qualities seem to be similar to those of natural teeth.
