Intaglio Surface of Full-arch Implant Supported Prosthesis

Résumé succinct

The purpose of the study is to determine if there is an association between the intaglio shape of full-arch implant-supported prosthesis and marginal bone level around implants. The intaglio shape can be present as concave or convex and, depending on that, it can lead to more plaque accumulation on the fitting surface of the prosthesis. Null Hypothesis (H0): Full-arch implant supported prosthesis with an increased depth of the intaglio shape demonstrate similar marginal bone levels as prosthesis with a reduced depth of the intaglio surface. Alternative Hypothesis (H1): Full-arch implant supported prosthesis with an increased depth of the intaglio shape demonstrate increased/reduced marginal bone levels compared to prosthesis with a reduced depth of the intaglio surface.
