Part A: Removable Partial Dentures
• Replaces one or more teeth in one arch
• Retained and supported by underlying tissues and remaining teeth

Advantages of a Removable Partial
Less expensive than fixed
prostheses
Proper occlusal plane is
maintained
Fewer intraoral procedures
than fixed pros.
May support periodontally
involved teeth
Stabilizes the arches
Restores function when
no distal teeth present
Restores
long span
of lost
dentition
Easier for good oral hygiene of
abutments
Easily repaired and adjusted

Contraindications for a Partial
Lack of sufficient number of naturalteeth properly located in the arch
Lack of teeth with adequate rootsupport to retain the appliance
Rampant caries or gross periodontalconditions of remaining teeth
Poor oral hygiene with no motivationto improve oral conditions
