title: Reduction of precocious peri-implant resorption cone.
abstract: OBJECTIVE
  After implant-insertion, bone tissue, newly-formed on peri-implant crest, undergoes to a mild marginal osseous readjustment due to build-up of inflammatory cell tissue (ICT). The present study verifies the possibility to limit bone resorption by placing implant fixtures 0.5 mm outside cortical bone edge.
  
  
  METHODS
  A clinically-controlled randomized study on 100 implants has been performed to compare early resorption process of implant fixtures placed 0.5 mm outside cortical bone edge with implant-fixtures inserted according to juxtacortical bone conventional protocols.
  
  
  RESULTS
  After 6 months, bone implant level was higher with emersion approach (-1.01±0.54 mm, mean±SD) than with submerged treatment (-1.56±0.5 mm) (P<0.001).
  
  
  CONCLUSIONS
  Factors to achieve an excellent result at mean-long term seem to be very good, even though the latter have to be confirmed by follow-up.
