Abstract
Conventional osteotome-mediated transalveolar approach might bring out patient’s discomfort related to the malleting and unexpected sinus membrane perforation could be overlooked due to its blindness in access. A modified lateral approach, so call hybrid technique, introduced by Jung et al. utilized a minimized linear shaped osteotomy at the lateral wall to provide visual and instrumental access while elevating the sinus floor with transalveolar approach. Through the linear osteotomy, the Schneiderian membrane was detached limitedly in the internal surface of the floor prior to the drill penetration into the sinus and lifting with the hydraulic plug. Two clinical cases that used hybrid technique for the sinus floor elevation spontaneously with multiple implant placements were shown in the present reports. Preoperative remaining bone height ranged from 5 mm to 7 mm and 10 mm length of implants were installed with the vertical bone augmentation of 5~6 mm, which maintained through the follow-up period of 4 and 6 years. None of the cases were involved with the membrane perforation. From the clinical results, hybrid technique was considered to be an effective and noninvasive procedure for sinus floor elevation with spontaneous implant placement in atrophied posterior maxilla.
