Study Notes
Preparation and Advantages
- Preparation is limited to enamel and the labial surface remains intact
- Advantages include:
- Conservative (within enamel)
- No need for anesthesia
- Esthetic
- Fixed prosthodontics
- Bonding
Materials for RBB
- Three different materials can be used:
- Metal
- Ceramic
- Fiber-reinforced
Adhesive Resin Cements
- Contain 4-META, such as C & B Metabond (Parkell)
- Heating the alloy (precious Alloys) promotes the bond between 4-Meta (resin cement) and copper-rich deposit formed by heating precious alloys
Potential Complications
- Structural damage
- Shade match deterioration, which can result from:
- Natural tooth discoloration
- Porcelain changes
Design and Retention
- Single retained “Cantilever” or two retained RBB designs are possible
- Two-retainer all-ceramic RBBPDs demonstrated a high incidence of unilateral framework failure, leading to a cantilevered design
- All-ceramic RBFPDs made from glass-infiltrated alumina ceramic In-Ceram have a high fracture rate within the first years of clinical service, particularly with two-retainer designs
