Minimally invasive techniques for sinus floor elevation using dental implants among Indians.

Abstract

It is of interest to compare conventional lateral window technique, trans-alveolar technique with minimally invasive technique like modified trephine technique and antral membrane balloon elevation technique for sinus floor elevation in placement of dental implants. The current study included 140 participants (191 dental implants) who had maxillary posterior edentulous regions and had low sinuses and insufficient alveolar ridges but had chosen an implant-retained prosthesis. The minimally invasive techniques of sinus augmentation can be suitable alternative to conventional traumatic techniques due to low incidence of pain, gingival swelling. Moreover, the success rate of implants and increase in total bone height was almost same in minimally invasive techniques of sinus augmentation as compared to conventional traumatic techniques.
