Q

What are the benefits of SDA?

A

provides adequate chewing function

dental aesthetics is not significantly compromised

some tooth migration may occur but SDAs provide occlusal stability

avoids the need for potentially damaging removable partial dentures

17
Q

Are RPD damaging to oral health?

A

potentially

Pt needs to control plaque

18
Q

biological - fungal/bacterial
