Centric relation registration using an anterior deprogrammer in dentate patients
1Prosthodontics Department, Naval Dental School, National Naval Dental Center, Bethesda, MD 20889, USA.
Summary
This study introduces a new technique for registering centric relation in patients using an anterior deprogrammer. This method helps prevent muscle splinting and reduces operator error for accurate dental impressions.
Area of Science:
- Dentistry
- Dental Occlusion
- Biomechanical Engineering
Background:
- Registering centric relation is crucial for accurate dental restorations.
- Conventional manipulative techniques can introduce operator-induced errors.
- Muscle splinting can interfere with achieving a true centric relation record.
Purpose of the Study:
- To describe a novel technique for registering centric relation in dentate patients.
- To utilize an anterior deprogrammer to prevent muscle splinting during centric relation registration.
- To provide a method for unassisted patient closure into centric relation, minimizing operator error.
Main Methods:
- A specific technique involving an anterior deprogrammer is detailed.
- Patients are trained to close into centric relation unassisted.
- Verification is achieved by visually aligning mandibular incisors with occlusal markings on the deprogrammer attached to the maxillary cast.
Main Results:
- The described technique allows patients to achieve centric relation independently.
- Operator-induced error is eliminated through unassisted closure.
- Visual verification of precise alignment is possible using the deprogrammer's markings.
Conclusions:
- This technique offers a reliable and accurate method for registering centric relation.
- The use of an anterior deprogrammer enhances accuracy by preventing muscle splinting.
- The method provides a verifiable and reproducible means of achieving centric relation records.
