A Novel Indirect-Direct Technique for Provisional Fixed Partial Denture Fabrication in Nonparallel Abutment Cases

Area of Science:

• Dentistry
• Prosthodontics
• Dental Materials

Background:

• Fabricating provisional fixed partial dentures with nonparallel abutments is challenging.
• Traditional methods often compromise esthetics and hygiene due to visible clasps or bulky components.

Purpose of the Study:

• To describe an innovative technique for provisional fixed partial dentures that addresses nonparallel abutments.
• To eliminate the need for clasps while ensuring stability, esthetics, and hygiene.

Main Methods:

• Incorporation of a triangular rest seat with a dovetail configuration for multidirectional stability.
• Reinforcement of the rest seat and sealing with composite resin for durability and esthetics.
• Segmental fabrication approach for precise adaptation to nonparallel abutments.

Main Results:

• The technique successfully eliminates the need for visible clasps.
• Achieves multidirectional stability and structural integrity of the provisional prosthesis.
• Provides a clean, esthetic finish with improved hygiene and functional reliability.

Conclusions:

• This innovative technique offers a conservative and patient-friendly solution for provisional restorations with nonparallel abutments.
• It effectively balances esthetic and hygienic demands with mechanical retention.
• Improves overall functional reliability and patient comfort.
