Resin Bonded FPD and Cingulum Rests Flashcards
Which canine can have either an incisal or cingulum rest seat?
Mandibular
What are resistance features used in a tooth preparation for an acid-etched resin bonded reatainer?
Grooves
What is a bridge that uses conventional full crown as a retainer on one of the abutment teeth and a RBFPD as the retainer on the other abutment tooth of the FPD?
Combo bridge
What is used to etch tooth prior to placing the RBFPD?
40-50% Phosphoric acid
Vertical stops on the lingual of incisors, cingulum on canine, or occlusal rest seats on PM and M function to do what?
Resist gingival displacement of RBFPD
Tooth preparation for RBFPD is how deep?
Only in enamel
What does Tin plating do to noble metals?
Makes noble metals good for bonding
Does Air abrasion with Aluminum oxide roughen metal for micromechanical retention?
No, just cleans it
What is Panavia?
Chemically active resin cement to adhese to metal for bond strength
With what type of RBFPD can the Lost Salt technique increase retention, or can be done with Aluminum Oxide air abrasion?
Virginia Bridge
With what RBFPD do you cast a net-like mesh to cover abutment teeth, requires no etching , but must fit tooth intimately initially as it is hard to adapt?
Cast Mesh FPD
With what RBFPD do you use electrochemical pitting to etch metal to increase its retention?
Maryland Bridge
What type of RBFPD uses a wing-like retainer with funnel shaped perforations that combine mechanical retention and Silane coupling agent to adhere metal and enamel?
Rochette bridge
What are 5 techniques for bonding a metal framework to tooth enamel for a RBFPD?
- Rochette bridge
- Maryland bridge
- Cast Mesh FPD
- Virginia bridge
- Cement
What are some advantages of resin-bonded fixed partial dentures (RBFPD)?
- Minimal reduction
2. Supergingival margins
