The role of orthodontic extrusive remodeling in the enhancement of soft and hard tissue profiles prior to implant placement: a systematic approach to the management of extraction site defects.

A classification scheme that systematizes the wide range of regenerative potential of common extraction site topographies is presented. Within this system, the parameters for immediate implant placement and preliminary ridge augmentation are discussed. In addition, a new adjunctive role for orthodontic extrusion is introduced. This approach is intended to manipulate "hopeless" teeth to modify their local defect environments, thereby enhancing the predictability of subsequent implant placement at those sites.
