Abstract The present study was conducted to evaluate the maxillary sinus lifting technique using a palatal approach versus maxillary sinus lifting technique using a buccal antral approach. This study was carried out as a controlled clinical trial, the study sample included 14 patients. The sample was selected conveniently to fulfill a list of inclusion and exclusion criteria. All patients were divided into two equal groups, and had gone maxillary sinus lifting together with implant placement, group1 :( study group) seven patients had sinus lifting through the palatal approach technique, and group2 (control group) seven patients had maxillary sinus lifting using buccal antral approach technique, with simultaneous implant insertion in both groups. The selected patients’ age was ranged between 33-59 years with mean of 44.5 years. Regarding the number of implants placed within the sinus lifting, 17 implants were placed in group 1 (palatal approach) and 15 implants were placed in group 2 (buccal approach). The surgical procedure was performed for group 1 by raising a palatal mucoperiosteal flap and accessing the maxillary sinus area for lifting through a piezoelectric palatal window osteotomy, then implant placement was made simultaneously with sinus lift. The surgical procedure was performed for group 2 by raising a buccal mucoperiosteal flap and accessing the maxillary sinus area for lifting through a piezoelectric buccal window osteotomy, then implant placement was made simultaneously with sinus lift. 123 Clinical results revealed superiority of group 1 compared to group 2 in postoperative minimal degree of pain, edema, and wound healing. None of the implants had failed in both groups with a survival rate 100%. Radiographic evaluation revealed that in group 1 there was significant increase in bone density around dental implants and less marginal bone loss postoperatively. However in group 2 a higher vertical amount of bone gained around implants postoperatively compared to group 1. Radiographic results revealed also that despite the fact that all implants were placed without any grafted material simultaneously with sinus lifting in the present study, bone formation was evidenced and recorded around all implants at 6 months postoperatively in both groups. |
