Efficacy of Autogenous Tooth Plates for the Treatment of Peri-implant Bone Dehiscence Following Immediate Implantation in Maxillary Esthetic Zone: Randomized Clinical Trial

Patients with missing teeth face the prospect of tooth replacement either through the use of removable prostheses, fixed natural teeth-supported prostheses, or implant-supported prostheses. In many circumstances, implants are the alternative to fixed or removable prosthetic appliances.

One of the various indications of implant therapy is the replacement of periodontally hopeless teeth. The successful use of dental implants for more than 3 decades has been extensively documented for both conventional and immediate implant therapy.

The installation of implants in extraction sockets was advocated as a means to reduce the number of surgical procedures; to preserve the dimensions of the alveolar ridge; to reduce the interval between the removal of the tooth and the insertion of the implant supported restoration and furthermore, it may enhance osseointegration by taking advantage of the natural bone healing process around the implant.

A variety of regenerative techniques using combinations of bone grafts and barrier membranes have been suggested to promote bone regeneration in localized defects at implants placed into extraction sockets (Mayfield 1999). Bone substitutes were used to fill the marginal void between the implant and the bone, and barrier membranes were placed to protect the site during healing.

In the presence of fenestration or dehiscence defects, the potential for spontaneous bone formation at such defects is poor, so it is advised to use augmentation procedures for bone enhancement. Bone augmentation procedures are effective in promoting bone fill and defect resolution at implants placed in post-extraction sites, and are more successful with immediate and immediate-delayed placement than with conventional delayed placement.
