Официальное название
Effect of the Intaglio Surface of Full-arch Implant-supported on Marginal Bone Level: A Cross-sectional Study
Обзор
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.
Подробное описание
The investigators will review dental records from the university and call eligible individuals for an appointment. During the research visit, the investigators will take new x-rays for marginal bone level assessment and a digital scan of the prosthesis to assess the shape of the intaglio. Also, remove the prosthesis, perform clinical measurements and collect plaque samples from the prosthesis and the implant sulcus. then, implants and prosthesis will be cleaned and placed in position.
The study will have only one appointment where every measurement will be assessed in this visit.
