## TL;DR

This paper presents a new digital method for creating a provisional obturator for patients with limited mouth opening by using a mirroring technique and intraoral scanning.

## Contribution

The novel contribution is a streamlined digital workflow for virtual reconstruction of obturators using mirroring and intraoral scans.

## Key findings

- The mirroring technique allows digital reconstruction of the defect area using the intact maxillary arch as a reference.
- The method reduces the need for extensive laboratory procedures, improving prosthetic fabrication efficiency.
- The approach simplifies the impression-taking process for patients with trismus.

## Abstract

Capturing impressions for maxillary defect patients with trismus is challenging due to limited mouth opening and defect complexity. This study introduces an innovative digital technique that highlights virtual reconstruction through the integration of intraoral scanning and a mirroring approach. Using the intact maxillary arch as a reference, the defect area is digitally reconstructed to design a provisional obturator with a streamlined workflow. By eliminating the need for extensive laboratory procedures, this method significantly enhances the efficiency of prosthetic fabrication and simplifies the overall impression‐taking process.
