Abstract

Despite validated surgical techniques and the development of biomaterials, the procedures aimed at increasing the maxillary bone volume by sinus floor elevation have complications with various degrees of relevance. The perforation of the Schneiderian membrane is one of the most frequent events while performing the detachment of the membrane and it can increase the risk of iatrogenic sinusitis, impairment of functional homeostasis, dispersion of the graft material in the antral cavity as well as its bacterial colonization with a subsequential failure of the procedure. This report presents a case where transcrestal sinus lift was performed using Flusilift (Sweden & Martina, Due Carrare PD), a new instrument that allows fluid dynamic elevation of the sinus floor using saline solution to detach the Schneider’s membrane in an atraumatic way without using a sinus elevator and obtain an adequate alveolar ridge regeneration using hyaluronic acid in gel formulation to support an implant placement. Hyaluronic acid seems to play a key role in wound healing and contributes to a faster bone neoformation in bone regeneration procedures.

Highlights

The Sinus Floor Elevation technique, first described by Boyne and James in 1980 [1], aims to obtain an adequate bone regeneration in order to perform implant surgery and place implants within maxillary sinus in atrophic maxillary alveolar ridge.The procedure is performed by osteotomy of the lateral wall of the maxillary sinus, followed by Schneiderian membrane elevation and placement of autogenous particulate bone graft between the membrane and the alveolar ridge
Bone augmentation is generally provided by grafting the sinus cavity with autogenous bone, bone substitutes, or a combination of these biomaterials [2]
The significant advantage of this system with respect to conventional osteotomy techniques is the use of drills that, when used with depth stops, make it possible to gradually and predictably raise the Schneiderian membrane in steps of 1 mm at a time, conserving its integrity
