Facebow transfer is a procedure used in prosthodontics to record the spatial relationship of the maxillary arch to the patient/s skull and transfer this relationship to an articulator. This is particularly important for complex cases involving multiple fixed restorations or full arch reconstructions to ensure accurate articulation and occlusal harmony.

In children, mandibular fractures typically heal rapidly, and clinical examination (such as checking for pain, mobility, and malocclusion) is often sufficient to assess bony union after an appropriate healing period. Imaging techniques like OPG or CT scans are generally reserved for initial diagnosis, complex cases, or suspected complications rather than routine follow-up for simple, well-managed fractures.

Explanation: In bilateral balanced occlusion, if the incisal
guidance is steep, it is necessary to create a compensating curve that is also
steep to maintain balanced occlusion during lateral movements. This helps to
ensure that the occlusal contacts remain balanced and stable, preventing tipping
or dislodgment of the denture during function. The other options do not
adequately address the need for balance in occlusion.

Oral and Maxillofacial SurgeryPlain catgut is contraindicated in oral surgery due to its tendency to cause a pronounced tissue reaction. This reaction can lead to increased inflammation and a delay in the healing process, making it less suitable for procedures in the oral cavity where optimal healing is crucial.

SOLUTION · Linder Harth index: This analysis is very similar to Pont’s analysis except that a new formula has been proposed to determine the calculated premolar and molar value. · Korkhaus analysis: This analysis is also very similar to Pont’s analysis it makes use of Linder Harth’s formula to determine the ideal arch width in the premolar and molar region.
· Pont’s in 1905 presented a system whereby the measurement of the four maxillary incisors automatically established the width of the arch in the premolar and molar region. If measured value is less than calculated value, it indicates the need for expansion.
In addition this analysis utilizes a measurement made from the midpoint of the inter-premolar line to a point in between the two maxillary incisors.
· Bolton’s analysis: The Bolton’s analysis helps in determining disproportion in size between maxillary and mandibular teeth.

Oral PathologyDiastema (spacing between teeth) is never directly associated with TMJ pathosis. TMJ disorders commonly cause open bite due to condylar resorption or growth disturbances, closed bite due to posterior teeth super-eruption, and traumatic occlusion due to altered mandibular positioning. Diastema is typically related to tooth size-arch length discrepancies, developmental factors, or periodontal disease, not TMJ dysfunction.
