Abstract:

Knowledge of the factors that cause complications and failure in fixed prosthodontics enhances our ability to develop effective treatment plans, facilitates success, promotes optimal doctor-patient communication regarding anticipated treatment outcomes and provides early diagnosis of problems encountered during long-term maintenance. This presentation will identify the most common complications encountered with resin bonded prostheses and describe methods of minimizing or preventing their occurrence as well as managing the complications when they occur.

Outline:

1. Indications and limitations of resin bonded prostheses
2. Most common complications that occur with resin bonded prostheses
3. Debond rates
4. Diagnosis and treatment planning factors that affect debonding
   1. Diagnosis and treatment planning
      1. Effect of span length
      2. Effect of occlusal forces
      3. Effect of mouth location, gender, and age
5. Incidence of tooth discoloration
6. Caries incidence
7. Porcelain fracture incidence
8. Effect upon periodontal health
9. Cantilever designs and their impact upon success
10. Other diagnosis and treatment planning factors
    1. Tooth condition
    2. Mesiodistal dimension of edentulous space
    3. Abutment tooth contours
    4. Effect of splinting and multiple adjoining retainers
    5. Impact of mobile abutment teeth
    6. Effect of tooth translucency
11. Tooth preparation principles
    1. Area of tooth coverageCoverage of proximal and lingual surfaces
    2. Preparing proximal surfaces so they are faciolingually convex
    3. Creating adequate occlusal clearance
    4. Use of a peripheral finish line
    5. Benefit of lingual ledges or occlusal rests
    6. Impact of proximal grooves
    7. Use of a proximal groove combined with lingual groove(s)
