Abstract:
Transcrestal maxillary sinus floor elevation is an effective method to solve the problem of insufficient bone height in the posterior maxillary region.However,current methods,such as osteotome sinus floor elevation,cushioned grind-out technique,Smart Drill technique,etc.,require specialized surgical tool boxes.In this article,we introduce a new method of transcrestal maxillary sinus elevation that uses built-in reamers of various implant systems to scrap residu-al bone at the sinus floor and uses the implant to push the sinus membrane during implant placement.This technique is easy to operate and time saving and has a low rate of sinus membrane perforation.After a one-year follow-up observa-tion of 146 people and 175 implants,the endo-sinus bone gains were 5.00(4.70,5.30)mm and 2.10(1.40,2.70)mm in the group of 3 mm≤residual bone height(RBH)<5 mm and the group of 5 mm≤RBH<8 mm,respectively,which can meet the clinical requirements of implant stability.This technique is suitable in generalizing dental implantation.
