This study introduces a digital protocol for fabricating occlusal devices, simplifying mandibular deprogramming and computer-aided design (CAD) processes. The method enhances reproducibility and reduces chair time for dental professionals.
Area of Science:
- Dentistry
- Biomaterials Engineering
- Digital Health
Background:
- Fabricating occlusal devices presents challenges in clinical mandibular deprogramming and complex computer-aided design (CAD).
- Current methods can be time-consuming and require significant technical expertise.
Purpose of the Study:
- To present a novel, fully digital, two-step protocol for occlusal device fabrication.
- To overcome the difficulties associated with mandibular deprogramming and CAD in occlusal appliance design.
Main Methods:
- An initial anterior deprogramming phase using a leaf gauge.
- Fabrication of a 3-dimensionally (3D) printed anterior guide for consistent mandibular positioning.
- Utilizing a digital workflow for streamlined appliance design and production.
Main Results:
- The protocol simplifies the capture of a consistent mandibular position.
- The staged approach potentially improves design reproducibility for 3D printed occlusal devices.
- This method may reduce the need for extensive occlusal adjustments and follow-up appointments.
Conclusions:
- The proposed digital protocol offers an efficient solution for occlusal device fabrication.
- This technique addresses key clinical and technical hurdles, potentially improving patient outcomes and practice efficiency.
- The 3D printing integration facilitates reproducible and accurate occlusal appliance delivery.
