Managing bruxism and temporomandibular disorders using a centric relation occlusal device

Area of Science:

• Dentistry
• Biomaterials Science

Background:

• Bruxism and temporomandibular disorders (TMD) are common conditions requiring effective management strategies.
• Occlusal devices, such as centric relation occlusal (CRO) devices, are utilized in managing these conditions.
• Challenges exist in patient adaptation to occlusal devices due to variations in design and fabrication.

Purpose of the Study:

• To discuss the rationale, indications, and fabrication methods for centric relation occlusal (CRO) devices.
• To detail preferred fabrication techniques for CRO devices, emphasizing laboratory procedures.
• To highlight the importance of precise fabrication and delivery for successful patient outcomes in managing bruxism and TMD.

Main Methods:

• Review of five methods for fabricating occlusal devices.
• Detailed discussion of two preferred fabrication methods: one using heat-cured acrylic resin, the other using a heat-vacuum machine, thermoplastic splint resin, and autopolymerizing acrylic resin.
• Emphasis on the laboratory phase and precise clinical application.

Main Results:

• The successful management of bruxism and TMD using CRO devices is supported by existing literature.
• Precise fabrication and delivery of CRO devices, incorporating mutually protected articulation, can overcome patient adaptation issues.
• Specific fabrication techniques using acrylic resins and thermoplastic materials are presented.

Conclusions:

• Centric relation occlusal (CRO) devices are valuable tools in the management of bruxism and temporomandibular disorders.
• Meticulous attention to occlusal morphology, anterior guidance, and centric relation during fabrication is crucial.
• Skilled fabrication and delivery of CRO devices enhance patient adaptation and treatment success.
