Clinical and experimental dental research·2025

Bilateral buccal registration offers the highest accuracy for virtual interocclusal registration in fully dentate patients. This method ensures precise maxillomandibular alignment for dental treatments.

Area of Science:

Dental Technology
Digital Dentistry
Maxillofacial Prosthetics

Background:

Accurate maxillomandibular relationship determination is crucial for restorative and esthetic dentistry.
Virtual interocclusal registration is a key component in digital dental workflows.
Evaluating different registration strategies is essential for optimizing digital treatment planning.

Purpose of the Study:

To compare the accuracy of three virtual interocclusal registration strategies.
To assess registration accuracy in a fully dentate in vitro model.
To identify the most reliable method for maxillomandibular alignment in digital dentistry.

Main Methods:

Compared bilateral buccal, unilateral buccal, and anterior registration strategies.

Keywords:

Measuring Maxillary Posterior Tooth Movement: A Model Assessment using Palatal and Dental Superimposition

Published on: February 23, 2024

Used two fully dentate resin models and three intraoral scanners for digitization.

Evaluated accuracy by superimposing intraoral scans with a high-precision reference file.

Main Results:

Bilateral buccal registration showed significantly higher accuracy across the entire dental arch.
Unilateral buccal and anterior registration accuracy decreased with increasing distance from the registration site.
No consistent trend was observed between unilateral buccal and anterior registration methods.

Conclusions:

Bilateral buccal registration provides superior accuracy for maxillomandibular alignment in fully dentate patients.
This finding supports the use of bilateral buccal registration for precise digital dental workflows.
Optimized registration accuracy enhances model analysis, treatment planning, and restoration fabrication.
