Overlay occlusion rim technique to facilitate the recording of maxillomandibular relationships

Full-Mouth Rehabilitation of a Patient with Sjogren’s Syndrome with Maxillary Titanium-Zirconia and Mandibular Monolithic Zirconia Implant Prostheses Fabricated with CAD/CAM Technology: A Clinical Report

“…Subsequently, verification devices were fabricated using low-shrinkage PMMA resin (Pattern Resin LS; GC America Inc., St. Alsip, IL, USA) and were used to verify the accuracy of the definitive casts (Figure 5A). During the same appointment, occlusion rims were fabricated to record the maxillomandibular relationships, aided by the verification devices [35] (Figure 5B-D).…”

“…Subsequently, verification de vices were fabricated using low-shrinkage PMMA resin (Pattern Resin LS; GC Americ Inc., St. Alsip, IL, USA) and were used to verify the accuracy of the definitive casts (Figur 5A). During the same appointment, occlusion rims were fabricated to record the maxillo mandibular relationships, aided by the verification devices [35] (Figure 5B-D). The definitive casts were articulated in a semi-adjustable articulator (Denar Omni Track; Whip Mix Corp., Louisville, KY, USA), and maxillary and mandibular artificia tooth arrangements were fabricated (Figure 6).…”

Centric relation—A biological perspective of a technical concept

“…Indeed, alongside claims to abandon the dogmatic use of CR, 35 there have also been proposals to modify, from a technical usefulness viewpoint, the definition of centric relation 79–81 . Thus, while it seems reasonable to suggest that there is a general agreement on the fact that CR is still viewed too dogmatically, criticism in the form of nihilism should be abandoned in favour of constructive reasoning and critical thinking to find the best possible strategy to move towards evidence‐based dentistry.…”

“…69,77,78 Indeed, alongside claims to abandon the dogmatic use of CR, 35 there have also been proposals to modify, from a technical usefulness viewpoint, the definition of centric relation. [79][80][81] Thus, while it seems reasonable to suggest that there is a general agreement on the fact that CR is still viewed too dogmatically, criticism in the form of nihilism should be abandoned in favour of constructive reasoning and critical thinking to find the best possible strategy to move towards evidence-based dentistry. Based on that, the biological reasons for abandoning the current CR concept on one hand have been previously explained, and the technical reasons for maintaining a modified CR concept for technical reasons on the other hand will be reviewed below.…”
