Using tissue engineering and regenerative medicine in sinus lift

IntroductionInsufficient bone volume is a common problem in using implant-supported prostheses in posterior maxilla region. This limitation is caused by the presence of maxillary sinus together with alveolar bone loss. In sinus lift procedure we increase bone volume by using biomaterials or autologous bone. ObjectivesTo assess implant survival after following sinus augmentation techniques and especially compare different materials used for sinus augmentation. MethodsPubMed, Medline, and Google Scholar were searched from 2015 to 2017 with the following keywords (or combinations): regenerative medicine, tissue engineering, sinus lift, sinus augmentation. Relevant studies were chosen according to including criteria, reviewed, and the results were extracted. ResultsStudies have revealed high survival rate of implant-supported prostheses in sinus lift procedures. Lateral window technique that is done by preparing a window in the lateral wall of the sinus, has higher rate of survival and there was no statistical difference in survival between autologous bone and Heterologous bone graft, but better than Blood Without Graft Material in some studies and in a number of articles there was no difference between different materials. ConclusionMaxillary sinus lift is a well-known procedure before installing dental implants. New techniques and materials have presented and by using tissue engineering this procedure can be improved
