Before construction of the complete denture, patient"s natural dentition is evaluated because it helps in
1. Establishing vertical dimension
2. Arranging the teeth in balanced occlusion
3. Selection of form, shape, and size of the artificial teeth
4. All of the above
Prosthodontics
Answer: 3
Before construction of the complete denture, the patient's natural dentition is evaluated because it helps in all of the above: establishing vertical dimension, arranging the teeth in balanced occlusion, selection of form, shape, and size of the artificial teeth.
Most semiadjustable articulators have a fixed intercondylar distance of
1. 200mm
2. 160mm
3. 70mm
4. 110mm
Prosthodontics
Answer: 4
Most semiadjustable articulators have a fixed intercondylar distance of 110mm.
The impression material which would record the tissues with minimum pressure (mucostatic in nature) is
1. Zinc oxide eugenol
2. Plaster of Paris
3. Impression compound
4. All of the above
Prosthodontics
Answer: 2
The impression material which would record the tissues with minimum pressure (mucostatic in nature) is plaster of Paris.
The design of a removable partial denture (RPD) should be finalized before:
1) Any emergency dental treatment.
2) Any fixed prosthodontic procedures and the preparation of rest seats.
3) Extraction of third molars.
4) Extraction of a crown or bridge.
Prosthodontics Answer: 2
Explanation: Finalizing the RPD design before fixed
prosthodontic treatment ensures that the RPD can be properly integrated with
any existing or planned restorations, allowing for optimal function and
aesthetics.
Retromolar area should be covered in CD or distal extension RPD in order to
1. Provide the better marginal seal
2. To slow down the rate of resorption of alveolar bone in posterior area
3. Derive support from the underlying bone which is resistant to resorption
4. All of the above
Prosthodontics
Answer: 4
Retromolar area should be covered in CD or distal extension RPD in order to derive support from the underlying bone which is resistant to resorption.
For long span distal extension bases where rigidity is critical the major connector of choice is
1) Palatal strap
2) Anteroposterior palatal bar
3) Closed horse-shoe
4) Horse-shoe
Prosthodontics
Answer: 3
A closed horse-shoe major connector provides increased rigidity and support for
long-span distal extension bases in removable partial dentures. It helps
distribute forces evenly and enhances the stability of the prosthesis.
Broad palatel seal indicates
1. Type A palatal form
2. Type B palatal form
3. Type C palatal form
4. None of the above
Prosthodontics
Answer: 1
Broad palatal seal indicates type A palatal form.
Guiding planes are
1) Located adjacent to the edentulous area
2) Located far anterior to the edentulous area
3) Help in the stability of the denture
4) Provide a different path of insertion and removal
Prosthodontics
Answer: 1
guiding planes are flat, polished surfaces on the abutment teeth that guide the RPD along a specific path during insertion and removal. They are located adjacent to the edentulous area and are crucial for the proper seating and function of the denture.
