Occlusal Scheme
The planned pattern of tooth contacts and guidance in an implant-supported prosthesis, designed to distribute occlusal forces and protect the implant–bone interface.
Full Definition
An occlusal scheme in implant dentistry describes the deliberate design of how occlusal contacts are arranged across the prosthesis in both centric relation and excursive movements. Because osseointegrated implants lack the proprioceptive feedback of the periodontal ligament, occlusal design is especially critical to prevent overloading. Commonly prescribed implant occlusal schemes include mutually protected occlusion, group function, and lingualized occlusion for overdentures. Editors should note that 'occlusal scheme' is a broader planning concept, while 'occlusal overload' (already in database) refers to a specific pathological consequence of a poorly designed scheme.
Usage
Usage note: Always specify the type of occlusal scheme in clinical reports; a vague reference to 'appropriate occlusion' is not sufficient in peer-reviewed literature.
In Context
- "A mutually protected occlusal scheme was specified in the laboratory prescription to minimize lateral forces on the posterior implants." — Prosthodontic prescription form
- "The article failed to specify which occlusal scheme was employed, making reproducibility of the results difficult to assess." — Peer review critique
