title: Histologic analysis of clinically retrieved immediately loaded titanium implants: a report of 11 cases.
abstract: BACKGROUND
  Several investigators have reported high survival rates for early or immediately loaded dental implants.
  
  
  OBJECTIVE
  The aim of the present study was to analyze histologically the periimplant tissue reactions and the bone-titanium interface of clinically retrieved immediately loaded titanium implants.
  
  
  METHODS
  Eleven implants were inserted in the posterior jaw regions of six patients, serving as the most distal abutments of fixed provisional bridges and subjected to immediate occlusal loading. After a 10-month loading period, all 11 implants were retrieved with a trephine.
  
  
  RESULTS
  Mature bone was present at the interface of all implants. Some vertical bone loss was observed; this was more pronounced for cylindric implants. The bone-implant contact was approximately 60 to 65% for all implants.
  
  
  CONCLUSIONS
  The results demonstrate that osseointegration of dental implants can occur during immediate loading.
