La riabilitazione di arcate edentule o a dentatura gravemente compromessa mediante l'implantologia a carico immediato si è dimostrata nel corso degli ultimi decenni una procedura affidabile e predicibile. Il presupposto cardine per il successo clinico risiede nella rigorosa osservanza di opportuni accorgimenti che consentano di promuovere...

Scopo di questa ricerca è stato valutare la biocompatibilità e le caratteristiche meccaniche di framework in materiale composito rinforzato con fibra di carbonio per protesi fisse su impianti

Objectives: Short-term results indicated that the Brånemark Novum® protocol allowed successful rehabilitation of mandibular edentulism with immediately loaded implants. Yet, long-term studies are lacking. The aim of the present retrospective study was to report the 11-year outcomes for patients treated according to this protocol. Material and...

Several factors contribute to distortion of implant prostheses during fabrication and could prevent passive, accurate adaptation between implants and implant frameworks. The misfit between implants and restorative components may be significant and possibly lead to biologic or mechanical complications. The aim of this article is to describe a...

This prospective study reports the 6-year outcomes for patients rehabilitated with an immediate loading protocol of the maxilla (Columbus Bridge Protocol). In this study, 164 implants were inserted in 37 patients and loaded within 24 to 36 hours. Four implants failed during the first 6 months. At the 6-year follow-up, a mean bone loss of 1.52...

PURPOSE: The aim of this study was to analyze through a three-dimensional finite element analysis (3D-FEA) stress distribution on four implants supporting a full-arch implant-supported fixed prosthesis (FFP) using different prosthesis designs. MATERIALS AND METHODS: A 3D edentulous maxillary model was created and four implants were virtually...

Objectives: The aimof the present study was to investigate the biocompatibility and mechanical characteristics of dental implant frameworks made of carbon fiber composite. Methods: The biocompatibility of intact samples and fragments was evaluated by cell count and MTT test according to EN-ISO 10993-5:2009 directions. Destructive and...
