Implant placement in the maxillary tuberosity: the Summers' technique performed with modified osteotomes.
The maxillary tuberosity region is becoming increasingly involved in preprosthetic surgery as part of a comprehensive implant treatment planning. The lower success rates in osteointegrated implant placements seen in the posterior regions of the upper maxilla as compared to the anterior regions of the jaws, most often come from bone quality types and the presence of the maxillary sinus. In order to overcome these limitations and obtain a successful result in such a demanding area, several authors suggest that long implants (15.0 to 20.0 mm long) should be placed in the maxillary tuberosity region as an alternative to sinus floor elevation. The challenges frequently associated with the surgical placement of "maxillary tuberosity implants" (MTI), can be reduced through a "Ridge Expansion Osteotomy" (REO) procedure as described by Summers (1994). This indeed improves the recipient bed bone quality and causes no bone overheating. In order to improve this technique performed for MTI, in co-operation with Ing. Albanese G, authors have developed different prototypes of modified osteotomes. A case report using these new instruments is presented. Clinical and radiographic evaluations are obtained.
