his is the set of answers corresponding to the four condensed short answer questions, supported exclusively by the provided lecture material.

1. Complete Denture Occlusal Schemes

The five classifications of Complete Denture Occlusal Schemes provided in the sources are: Bilateral Balanced, Lingualised, Canine Guidance, Group Function, and Monoplane.

Bilateral Balanced Occlusion is defined as the bilateral, simultaneous posterior occlusal contact of teeth in maximal intercuspal position and eccentric positions.

The defining characteristic of Lingualised Denture Occlusion is that it articulates the maxillary lingual cusps with the mandibular occlusal surfaces in centric occlusion, working, and nonworking mandibular positions.

2. Occlusal Plane and Balance

The occlusal plane is defined as the imaginary plane established by the incisal and occlusal surfaces of the teeth. The two major anatomical lines used to orient the occlusal plane are the Interpupillary Line and Camper’s Line.

At least three factors that affect the attainment of Bilateral Balanced Occlusion are:

  1. Incisal Guide Angle
  2. Condylar Guidance
  3. Compensating curves (antero-posterior & transverse)
  4. Orientation of occlusal plane
  5. Cuspal Inclination

The primary function of introducing compensating curves into the occlusion is that they compensate for the space (known as Christensen’s Phenomenon) formed between the posterior occlusal surfaces during eccentric (translatory) mandibular movements.

3. Posterior Tooth Selection Criteria

When selecting artificial posterior teeth, Function is identified as the most important factor.

The mesiodistal width of the posterior tooth arrangement is governed by the length and slope of the mandibular ridge, extending from the distal of the canine to the anterior of the retromolar pad.

The cuspal inclination degrees associated with specific posterior denture teeth forms are:

  • Semi-anatomical: 10°, 20°, and 22°.
  • Non-anatomical: 0°.
  • (For comparison, anatomical teeth have inclines of 30°, 33°, and 40°).

4. Clinical Trial Insertion Assessment

During the Visit 4 Wax Try-in, three critical checks performed by the clinician (aside from aesthetics/teeth shade/shape/display) include:

  1. Occlusal Vertical Dimension (OVD)
  2. Phonetics
  3. Occlusal plane
  4. Midline and facial midline
  5. Extension posterior
  6. Maximum intercuspation
  7. Centric and eccentric interferences (Any combination of three is acceptable.)

The typical range for interocclusal clearance (freeway space) measured during the clinical check for Occlusal Vertical Dimension (OVD) is 2 – 5 mm.

The labiodental sounds (f, v, and ph) are considered an excellent test during the phonetics assessment because, to produce these sounds, the lower lip must be brought into contact with the incisal edges of the upper anterior teeth. This checks for the proper plane of occlusion and accurate placement of the anterior teeth.
