# Digitally Designed Semi-precision Attachment-Retained Cast Partial Dentures for Esthetics and Function: A Case Report

## TL;DR

This case report shows how digital dentistry can create esthetic and functional partial dentures using semi-precision attachments for a patient with complex dental needs.

## Contribution

The paper presents a novel application of digital technology in fabricating semi-precision attachment-retained partial dentures for improved esthetics and function.

## Key findings

- A custom extracoronal patrix on tooth 11 eliminated metal display and improved esthetics.
- A 3 mm increase in vertical dimension was achieved without complications over two years.
- Digital fabrication enabled accurate and predictable prosthetic rehabilitation for complex cases.

## Abstract

Removable partial dentures (RPDs) retained by semi-precision attachments are valuable alternatives to conventional clasp-retained prostheses, particularly in cases where esthetics and biomechanical stability are critical. With advancements in digital dentistry, customized attachments and frameworks can now be fabricated with high accuracy and predictability. This case report describes the prosthetic rehabilitation of a 66-year-old male patient with Kennedy Class II mod 1 maxilla and Kennedy Class I mandible using digitally fabricated crowns and a semi-precision attachment-retained RPD. A custom extracoronal patrix was incorporated on tooth 11, eliminating metal display and enhancing esthetics. A 3 mm increase in vertical dimension was achieved, and the patient has been followed up for two years without complications. This report underscores the role of digital technology in delivering esthetically driven and functionally sound outcomes in partially edentulous cases.
