Onlays are restorations which fit into cavity preparations and overlay the occlusal surface of a tooth or teeth. Onlays are retained by frictional or mechanical factors.,UMD: Dental prostheses designed to fit into a prepared dental cavity (i.e., inlays) to restore one tooth. Inlays are precision fitted and cemented to the surrounded intact tooth so that the patient cannot remove them. These prostheses (i.e., intracoronal restorations) are typically custom-made devices made of cast metal alloys (e.g., medium-hard gold), synthetic (e.g., acrylic) resins, or ceramics. Inlays are used to restore tooth contours and function; they are not intended to anchor fixed partial dental prostheses.,UMD: Dental prostheses designed to restore the posterior teeth by fitting around the remains of a tooth and covering one or more of the mesial, occlusal, and distal surfaces; they are precision fitted and cemented to
