Bite Splint with Increased Bite for Myorelaxation

Fabricating a custom bite splint with increased bite height to relieve muscle and joint pressure, particularly in patients with bruxism and TMD.

The fabrication of a bite splint with increased bite height is essential for relieving pressure on the muscles and temporomandibular joints, especially for patients experiencing bruxism or temporomandibular disorders (TMD). Increasing the bite height reduces muscle tension, improves mandibular positioning, and decompresses the temporomandibular joint (TMJ), promoting a relaxing effect.

Materials and Methods

• Input File: STL files of the patient’s mandible and maxilla, with the occlusal opening set at approximately 4 mm.
• Scanner Used: Prime Scan Sirona
• Software Used: Exocad

Digital Planning Steps

1. Scan Import: Load the STL files of the mandible and maxilla into Exocad.

2. Occlusion Analysis: Conduct an initial check of the mandibular-maxillary relationship in the software, confirming the planned occlusal opening.

3. Bite Splint Design: Create the bite splint model, adjusting the thickness to match the specified occlusal opening. Ensure uniform thickness across the occlusal surface.

   

4. Functional Adjustments: Simulate mandibular lateral and protrusive movements using a virtual articulator, checking for premature occlusal contacts and adjusting the design to avoid unwanted interference.

5. Finalization and Export: Finalize the digital splint model after adjustments and export the file for manufacturing.
