Abstract:
As a result of inadequate planning, poor judgment, or losing one's orientation during surgery, implants may be placed in positions or at angulations that are less than ideal. The purpose of this report is to describe an alternative technique for the correction of a malpositioned osseointegrated implant by means of a maxillary anterior single implant segmental osteotomy associated with a 'sandwich' bone graft technique. The technique described provides an alternative option for the surgeon faced with a malpositioned endosseous implant. It allows for a predictable result with preservation of the cervical gingival architecture, creates a more ideal environment for dental restoration, reduces treatment time compared to other techniques, and does so in a cost-effective manner.
