Abstract:
Traditional approaches to sinus floor elevation for dental implant placement have limitations. This technical report describes a modified transalveolar method of elevating the sinus membrane when 2 or more implants are placed simultaneously in a maxillary posterior area where the residual bone height is insufficient. With a narrow osteotomy connecting drilled holes, the Schneiderian membrane can be directly elevated with curettes as with the lateral approach, resulting in a reduced risk of perforation.
