Selective grinding for equilibrating complete dentures is best accomplished after processing when the dentures are
1) Rearticulated using original jaw relation record
2) Rearticulated with a new series of jaw relation
3) Equilibrated in the patient"s mouth
4) None of the above
Prosthodontics
Answer: 2
Selective grinding is a technique used to adjust the occlusion of complete dentures. It is best performed after the dentures have been processed and rearticulated with a new series of jaw relations to ensure that the occlusion is accurate and reflects the patient's current jaw relationship. This allows for more precise adjustments to be made, as the original records may not accurately represent the current occlusal relationship after processing.

The Camper’s plane passes from the
1. lateral commissure of the mouth to the inferior edge of the ear
2. orbitale to the middle of the tragus of the ear
3. ala of nose to the superior edge of the tragus of the ear
4. outer canthus of eye to the most poste rior point on the tragus of the ear
Prosthodontics
Answer: 3
The Camper’s plane passes from the ala of the nose to the superior edge of the tragus of the ear.
Articulators are classified into arbitrary positional and functional by
1. Beak
2. Posell
3. Boucher
4. Thomas
Prosthodontics Answer: 3
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.
Vomiting during impression making procedures may be prevented by
1. Sedating the patient
2. Injecting local anaesthetic
3. Asking patient to come on empty stomach
4. Change the impression material
Prosthodontics
Answer: 2
Vomiting during impression-making procedures may be prevented by injecting local anaesthetic.
The Camper’s plane passes from the
1. lateral commissure of the mouth to the inferior edge of the ear
2. orbitale to the middle of the tragus of the ear
3. ala of nose to the superior edge of the tragus of the ear
4. outer canthus of eye to the most posterior point on the tragus of the ear
Prosthodontics
Answer: 3
The Camper’s plane is a facial reference plane that passes from the ala of the nose to the superior edge of the tragus of the ear. This plane is used in facial and cranial anatomy to describe the orientation of various structures and is often referenced in the field of orthodontics and surgery. It is useful for assessing the facial profile and the relationship between the nose, ears, and other facial features.
The concept of occlusion that maintains that the anteroposterior plane of occlusion should be parallel with the denture foundation and not dictated by the horizontal condylar guidance is called
1. Lingualised concept
2. Balanced concept
3. Neutrocentric concept
4. Mutually protected concept
Prosthodontics
Answer: 3
The neutrocentric concept of occlusion emphasizes that the occlusal plane should be parallel to the denture foundation and not influenced by the horizontal condylar guidance. This approach aims to achieve a more stable occlusion by focusing on the relationship between the occlusal plane and the supporting structures.
