L'inserimento degli impianti in una posizione ideale, protesicamente guidata, può essere osta-colato dall'insufficiente disponibilità di volumi ossei nei siti postestrattivi di aree ad alta valenza estetica. Negli ultimi anni è stato proposto da diversi autori un approccio chirurgico, noto come preservazione dell'osso alveolare (Alveolar ...

PURPOSE: This in vitro study evaluated the adhesive strength of a technique to lute implant cylinders to metal frameworks in implant-supported prostheses and ensure a good passive fit. MATERIALS AND METHODS: Different height samples were tested: In group 1, implant cylinders were 5 mm long; in group 2, they were 10 mm long. A universal testing...

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...

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...

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...
