title: Autotransplantation with simultaneous sinus floor elevation.
abstract: BACKGROUND
  Autotransplantation of the third molar is a viable option for replacing missing molars and has some benefits. This case report showed successful autotransplantation with simultaneous sinus floor elevation and implant installation.
  
  
  METHODS
  The patient suffered a loss of maxillary molars and had a pneumatized maxillary sinus under the area in need of restorative treatment. Instead of implant installation in the molar area, we performed autotransplantation of the mandibular third molar with simultaneous sinus floor elevation with the aid of computer-aided rapid prototyping model.
  
  
  RESULTS
  Healing was uneventful. There were no subsequent long-term symptoms or discomfort in the transplanted area. Clinical examinations revealed no mobility of the transplanted tooth, and there was no radiographic evidence of root resorption or ankylosis at a follow-up visit 4 years after transplantation.
  
  
  CONCLUSIONS
  Autotransplantation with simultaneous sinus floor elevation is a potential treatment alternative to implant installation in selected cases.
