Bilateral elevation of the maxillary sinus using two different techniques - case report

Loss of teeth in the maxillary molar region often causes descending of maxillary sinus. Lateral, surgical extensive approach of sinus elevation is used for more implants placement. Transcrestal approach is used for the closed sinus elevation and immediate placement of the single implant with minimal surgical trauma. Balloon controlled is the new method of closed sinus elevation were space for postponed placement of 2-3 implants is being created with minimal surgical trauma. With salline solution filled syringe and adapted balloon catheter the membrane of the maxillary sinus is elevated up to 15 mm in vertical and horizontal dimension. It is minimally invasive technique for postponed implant placement, were more implants are indicated. Disadvantage is bigger risk or perforation of the membrane due to minimal visibility. In our patient bilateral elevation of the maxillary sinus has been performed by using two different techniques. Lifting of the right maxillary sinus was done by the balloon controlled technique (transcrestal approach). The augmentation has been done with alloplastic bone filler. lifting of the left maxillary sinus was performed by forming lateral fenestration on the buccal plate followed by the augmentation with mixture of xenogenic bone filler and autologous bone. After 6 months of augmentation 3 implants on each side were placed and prosthetic suprastructure were completed within next 4 months. This case shows advantages and disadvantages of both techniques.
