Classification and Clinical rationale for FDP Flashcards
What are the advantages and disadvantages of resin-bonded FDP?
Advantages:
Minimal removal of tooth structure
Supragingival preparation, easy impression making
Interim restoration not usually required
Disadvantages:
Reduced restoration longevity
Space correction is limited
Good alignment of abutment teeth is required
Esthetics is compromised on posterior teeth
What are the indications and contraindications for resin-bonded FDP?
Indications:
Short edentulous space (one
tooth)
Healthy/Unrestored abutments (enamel surface)
Significant clinical crown length
Temporary restoration - space maintenance
Open bite
Contraindications:
Damaged abutments
Large edentulous area
Unfavorable angulation and
rotation of abutments
Parafunctional habits or heavy occlusal forces
Deep bite
Mobile teeth
Alloy allergy
What are the principles of tooth preparation?
Intra-enamel preparation
Supragingival margins
Maximize surface area for retainers
Bracing of abutments
Single path of insertion
Clearance for retainers
Rest seats
