Title Orthodontic Extrusion or Surgical Procedures Acceptable for Dental Implant Site Preparation
Clinical Question In a healthy dental patient, will the use of orthodontic extrusion of a tooth for preparation of a proposed dental implant site provide treatment benefits over traditional surgical preparation methods of a proposed implant site?
Clinical Bottom Line It has not been determined that orthodontic extrusion provides any benefits over traditional surgeries when preparing a dental implant site. (See Comments on the CAT below)

Key resultsOrthodontic extrusion appears to be a feasible and practical alternative to surgical procedures for dental implant site preparation. However, no studies were found that directly compared the two techniques.

The Evidence
In the article, a single standardized method of orthodontic extrusion was not employed in the case studies; and in a minority of cases, surgical procedures were required for either bone or gingiva augmentation. In addition, the literature did not include any cases where implants failed. While orthodontic extrusion appears to be a viable alternative to surgical procedures, clinical trials are necessary to provide quantitative and qualitative evidence as to whether or not orthodontic treatment provides any benefits over surgery. Potential benefits of orthodontic extrusion of non-restorable teeth prior to implant placement include increases in the amount of alveolar bone and gingival tissue available at implant sites. It also has the potential to reduce the need for bone grafting in association with dental implant placement, while benefitting the patient by reducing the need for periodontal surgery. In addition, orthodontic extrusion may be a less costly than surgical procedures.
Applicability This treatment is applicable for any healthy patient with a non-restorable tooth that needs to be removed in preparation for a dental implant.

A PubMed search conducted in April 2012 found a limited amount of related evidence. As mentioned in the CAT, there were still no studies that included a direct comparison of orthodontic extrusion procedures versus more conventional surgical procedures.
