The most common clinical complications associated with resin bonded prostheses are identified along with methods of minimizing or preventing them. Methods of managing the complications are described when they do occur.

Learning Objectives

Describe the indications and limitations of resin-bonded prostheses Identify the most common complications associated with resin-bonded prostheses
Know the debond rate associated with resin-bonded prostheses
Discuss the diagnosis and treatment planning factors that affect debonding
Describe the tooth preparation features that reduce or eliminate complications
Identify the appropriate metal thicknesses required in frameworks
Describe the methods used to retain resin cements to the metal framework
Discuss the appropriate cementation protocol

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

Most common complications that occur with resin bonded prostheses
Debond rates
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
Incidence of tooth discoloration
Caries incidence
Porcelain fracture incidence
Effect upon periodontal health
Cantilever designs and their impact upon success
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
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)
Design, thickness, and fit
1. Metal thickness dimensions
2. Cement-metal retention mechanisms
