Abstract
Background: Maxillary sinus lifting is a complex procedure with reported complications in the literature where the presence of sinus septa further complicates the procedure, they including membrane perforation, bleeding. Aim: The aim of this study is to decrease the incidence of membrane perforation which is the most common reported complication, and to determine whether the use of surgical guides could decrease the incidence of membrane perforation. Materials and methods: A total of 12 cases where blindly divided into 2 groups; Group (A) computer guided maxillary sinus lifting and Group (B) conventional sinus lifting, both groups received allogenic bone blocks for sinus augmentation with simultaneous implant placement. Cone beam CT was performed pre operatively for planning the number and position of implants to be placed and for fabrication of the surgical guide. Results: In all cases the Schneiderian membrane was successfully elevated except for one case in Group (A) where membrane perforation occurred and 2 cases in Group (B) Conclusion: The use of surgical guide in sinus lifting procedures decreases the incidence of membrane perforation working time and improve implant positioning.
