Instrument which has a 4 digit formulae is angle former.

In the design of cast circumferential clasps, the retentive terminal should ideally point away from the gingiva (toward the occlusal surface) to allow for proper engagement and retention without causing trauma to the gingival tissue.

The chamfer finish line has the highest risk of leaving unsupported enamel because it creates a curved transition that may leave thin, fragile enamel edges. The shoulder provides definite support, the shoulder with bevel adds strength, while the bevel alone provides gradual transition. The chamfer's curved nature can result in inadequate support for thin enamel margins.

Articulators are classified into arbitrary positional and functional by Boucher.
Arbitrary positional articulators hold the mandible in a pre-determined, fixed position that does not necessarily represent the patient's true centric relation or functional movements.
Functional articulators, on the other hand, aim to simulate the patient's individual centric relation and dynamic movements of the mandible, allowing for a more accurate representation of the patient's actual occlusion.
Boucher's classification system is based on the type of articulation and the way it records and transfers the patient's jaw movements to the dental casts.

Which of the following is likely to occur if the VDO is increased in a complete denture patient: clicking of teeth.

Oral examination of an edentulous patient should include digital palpation to evaluate undercut areas better.

Recontouring and selective grinding are procedures used to adjust the fit and function of complete dentures. These adjustments are often performed to eliminate any interference with the patient's normal masticatory (chewing) function or to correct any imbalances in the bite. By removing excess material and reshaping the occlusal surfaces, the dentist can address issues such as malocclusion or improper contact between teeth, thereby restoring a harmonious occlusion.

Orientation records are best transferred by face-bow record.

If freeway space is obliterated, it would result in all of the above: improper aesthetics, clicking sounds of the dentures, trauma to the underlying ridges.
