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

## TL;DR

A new dental technique creates better-looking and more comfortable temporary dentures for nonparallel teeth.

## Contribution

A novel indirect-direct technique using triangular rest seats and composite resin for provisional dentures in nonparallel abutment cases.

## Key findings

- The triangular rest seat with a dovetail configuration provides multidirectional stability without clasps.
- Segmental fabrication improves adaptation around nonparallel abutments.
- The technique enhances esthetics, hygiene, and mechanical retention in provisional restorations.

## Abstract

Fabrication of provisional fixed partial dentures in cases with nonparallel abutments presents a unique prosthodontic challenge, especially when esthetic and hygienic demands must be balanced with mechanical retention. Traditional approaches often utilize visible clasps or rely on non-esthetic stabilizing components that compromise patient comfort and appearance. This technical note describes an innovative technique that eliminates the need for clasps by incorporating a triangular rest seat with a dovetail configuration, designed to provide multidirectional stability. Reinforcement within the rest seat and sealing with composite resin ensures a clean, esthetic finish while maintaining the structural integrity and retention of the prosthesis. In addition, a segmental fabrication approach allows for precise adaptation around nonparallel abutments. This technique offers a conservative, patient-friendly solution that improves esthetics, hygiene, and functional reliability in provisional restorations.
