Indications for RPDs
(7)

Answer 27

• Edentulous area(s) too long or
numerous for a fixed prosthesis
• Need to restore lost soft and hard
alveolar tissue, especially in the anterior
region****
• Reduced periodontal support of
remaining teeth
• Need to distribute masticatory
stresses across the dental arch:
cross-arch stabilization
• No posterior abutment tooth
• Immediate replacement of teeth
• Attitude & desires of patient (economic
considerations)
