Most denture wearers consciously or subconsciously perform random, empty-mouth occlusal contacts throughout the day. Clearly, when complete dentures are supported by implants, this balance between retentive and displacing forces is greatly tipped in favour of the denture staying in place. The patrix designs take the form of a connecting bar/s or free-standing ball/magnetic abutments. It has to be considered that bone loss in the posterior part of the jaw leads to the necessity of relining in a high number of prosthesis.

To splint or not to splint oral implants in the implant-supported overdenture therapy? 1. The diaphragms seal off the one-way valves, preventing air reintroduction. Latter is associated with rapid wear of matrices or patrices of ball anchors, as well as locators. As with FPDs, the RPD can also restore an incomplete dentition, but with broader indications because of not-so-strict prerequisites. 3.
