Relining
Which condition is an extraoral factor that must be considered before recommending a removable prosthesis?
Motivation
What causes a pressure point on a removable prosthesis?

What is one advantage of using acrylic teeth instead of porcelain teeth in partial dentures?

What is a partial denture?
A removable denture when there are remaining teeth.
How does a full (complete) denture receive its support and retention?

What is the surgical procedure to recontour a residual ridge called?
Alveoplasty.
The _____ begins at the occlusal surface of the tooth and extends downward so that it partially encircles the tooth.
C-clasp.
How does a removable partial denture receive its support and retention?
Underlying tissues and remaining teeth that serve as abutments.
What factor is not considered when selecting teeth for a partial denture?
Patient’s dietary habits.
Which type of factors must be considered intraorally when recommending a removable prosthesis?
Musculature, salivary flow, residual alveolar ridge, oral mucosa, oral habits, and tori.
Which impression material is used for the final impressions for the creation of the baseplates and occlusal rims?
Elastomeric.
During fabrication of a complete denture, what does the dentist evaluate using the baseplate wax-occlusal rim assembly?
