The
two-component bridge system provides numerous advantages.
However, there are several contraindications, and a careful
case selection is required.
Advantages
- Conservative
tooth preparation
- Bridge
flecure premitting Class I mobility without fracture
- Nonmetallic
materials for optimal asethetics and reduced risk of allergy
- Two-phase
placement, eliminating pontic overcontouring
- Two
components, combining the resiliency of resin with the aesthetics
of porcelain
- Chairside
control of pontic shading
- High
bond strength of etched-resin framework, enamel, and porcelain
- Maximum
polymerization of resinous framework from designed use of
heat, light, and pressure curing with incorporation of glass-reinforced
fibers
Contraindications
- Teeth
that exceed Class I mobility
- Teeth
that are shorter (incissal to gingival) than 5 mm
