The localized management of sinus floor (LMSF) is one of key technologies in dental implant surgery, but the lining mucosa of maxillary sinus is easily impaled during LMSF surgery. This paper proposed a computer aided design method to construct 3-D finite element model of LMSF. Then the models are processed for analysis. Finally, the virtual surgery simulation was carried out from three aspects which include distance between the apex of bone condenser friadent and the maxillary sinus floor, the shape of maxillary sinus floor and the position of bone condenser friadent. The obtained conclusions can give dentists some directions to carry out clinical LMSF operations. Thus the surgical process can be better planned by dentists, so the success rate of operation also can be improved. In summary, the virtual LMSF surgery simulation has positive significance for both dentists and patients and this method can be applied in various kinds of surgeries to help clinical doctors plan the process of operations.
