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
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...

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...
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...
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...
PURPOSE: The aim of this study was to evaluate plaque accumulation and peri-implant tissue response adjacent to machined and dual acid-etched (DAE) titanium implant surfaces. MATERIALS AND METHODS: Two types of implants were used-control implants with a DAE surface in their apical portion and a machined coronal part, and test implants with a...
The aim of this paper is to describe a technique for sinus floor augmentation with a 1-step crestal approach where the residual bone is ≤ 7.5mm. 36 implants were installed in 25 patients in the atrophic posterior maxilla immediately after sinus floor elevation. Sinus floor elevation was performed with a crestal approach using either osteotomes...
Aims: This systematic review considers possible etiological factors and definitions of "peri-implantitis", as reported in the recent literature. Methods: An electronic search of databases plus a hand search of the most relevant journals published between January 2005 and September 2012 was performed. Results: The electronic search revealed...
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...
Full-arch immediate loading implant rehabilitations provide patients with compromised dentition an effective treatment to improve their aesthetic and function. Aim of this prospective cohort study was to investigate the correlation between masticatory ability and gastric emptying rates among these patients. Ten subjects (five men and five...

Prosthetic rehabilitation of the atrophic maxilla with implant-supported prostheses frequently represents a challenge because of inadequate quantity and quality of bone. The use of distal tilted implants has been proposed as a viable alternative to traditional protocols. The aim of this meta-analysis was to evaluate the survival rate and bone...
This study compared the surgical protocol efficacy of immediately and delayed loading implant therapy in edentulous maxillae opposed by natural or restored mandibular dentitions, over a 6 years plus period of observation. The selected outcome determinants included individual implant survival data, progressive measurements of peri-implant bone...

PURPOSE: This study was conducted to measure, in vitro, the chewing load forces transmitted through crowns made of different prosthetic restorative materials onto dental implants. MATERIALS AND METHODS: A masticatory robot capable of reproducing the mandibular movements and the forces exerted during chewing was used. The forces transmitted to...
Aims: The aim of the present in vitro investigation was to measure the vertical occlusal forces transmitted through crowns made of different restorative materials onto the simulated peri-implant bone. Methods: The study was conducted using a masticatory robot that is able to reproduce the mandibular movements and the forces exerted during...
