Long Term Implant Success in Regenerated Bone

Guide Bone Regeneration techniques have been demonstrate to be an effective and predictable treatment of peri-implant bone defects and alveolar ridge deficences.

The development period began in 1989 with the famous studies in rats and rabbits from Dr. Dahlin and continued until 1996 when the final surgical technique has been well defined. In the following 5 years, the results were confirmed with retrospective and prospective long term clinical studies. From 2001, the introduction in the market of new rougher or porous implant surfaces has augmented the risk of plaque accumulation and peri-implant tissue inflammation when the implant surface is exposed over the bone level. This is a frequent event when the bone regeneration is not complete or some remodelling happens at the bone crest. For this reason, the use of smoother implant surfaces or hybrid implants should be considered when GBR techniques are performed.

Aims:

  1. Understand the long term predictability of implants placed in regenerated bone.
  2. How implant surfaces could influence the long term implant success.
  3. How to use regenerative techniques predictably.
