A Reliable Alternative to Sinus Floor Elevation (SFE) Minimally invasive sinus grafting and implant placement without sinus floor elevation (SFE) by using autologous CGF (Concentrated Growth Factors) and Stem Cells CD34+ but with intentional perforation of the sinus membrane.

Abstract This article describes the placement of 84 implants in the posterior maxillary areas of 37 patients utilizing minimal invasive surgery. Following a certain protocol, the implants were introduced in to the sinus with intentional perforation of the Schneiderian membrane. Concentrated Growth Factors (CGF) and Novocor-Plus bone graft material (B&B, Italy), were used in these cases. At various stages during osseointegration, radiological examination was performed to assess the increase and maturation of bone structure formed around the implants and over the sinus floor. This unexpected event allowed the sinus membrane to reconstruct over the newly formed bone, proving how well an individual is capable of adapting under new conditions.

Introduction Partially or completely edentulous patients typically prefer an implant supported fixed denture. During treatment planning, it is often observed that SFE may be required in order to acquire the desired alveolar

ridge dimensions necessary to achieve in the implant initial stability and long term success. Previous investigations have reported maxillary sinusitis up to 20 percent of patients following SFE procedures. The complications of SFE predominantly consist of disturbed wound healing, haematoma, sequestration of bone and transient maxillary sinusitis. Postoperative acute maxillary sinusitis even cause implant and graft failure. The task for the dental practitioner placing the dental implants can be much simplified by using IPG-DET Technique providing great relief for patients if another expensive surgical procedure like SFE can be avoided. At first glance, an uneventful and unexpectedly fast placement of implants in the sinus cavity with intentional perforation of the sinus membrane would appear to have uncertain success and many other post-operative complications. The authors present the innovative IPG-DET Technique, which will demonstrate that SFE is no longer considered necessary. The combined employment of CGF (and Stem Cells CD34+) and bone grafting material within the osteotomy site by means of implant immersion was made in such a manner that the sinus can adapt to new conditions, which is, to form new bone around implants without the need to perform SFE. Implant placement has been done by utilizing minimal invasive surgery. March 2019
