Abstract
The aims of this study were to propose a minimally invasive lateral approach technique for maxillary sinus floor elevation (MSFE) with simultaneous implant placement and to evaluate the surgical outcome and complications of this technique. This study reviewed 49 surgeries of MSFE with simultaneous implant placement (n = 83) using a minimally invasive lateral approach. A circular shape window with a diameter of 5 to 6 mm and an area of 20–30 mm2 was made on the lateral wall of the maxillary sinus. After elevation of the Schneiderian membrane, the xenograft was used for bone grafting. The MSFE was possible with a minimum-sized window in 47 of 49 cases. For the remaining 2 cases, MSFE with a minimum-sized window was failed. In one case, it was expanded to be more than 30 mm2 to repair the membrane perforation. In another case, MSFE was performed by forming two minimum-sized windows. Post-operative bleeding after MSFE occurred in one anticoagulant-treated patient. There was no failed implant during the follow-up period (mean 22 months). A minimally invasive lateral approach through a small circular window with a diameter of 5 to 6 mm is a feasible and safe technique for MSFE with simultaneous implant placement.
Highlights
Dental implant treatment is needed to restore the function and aesthetics of an edentulous patient
The Schneiderian membrane which is located on the maxillary sinus cavity can be elevated and bone-grafting materials can be used to fill in the space between the elevated membrane and the maxillary sinus floor
All surgeries were performed in the department of dentistry at Gangneung Asan Hospital between May 2017 and December 2019. This clinical study was approved by the Institutional Review Board (IRB) of Gangneung Asan Hospital (IRB No: 2021-02-001)
Summary
Dental implant treatment is needed to restore the function and aesthetics of an edentulous patient. Insufficient bone for implant placement is frequently observed for a maxillary posterior alveolar bone [1]. For such cases, a maxillary sinus floor elevation (MSFE) can be considered to place the dental implant. The Schneiderian membrane which is located on the maxillary sinus cavity can be elevated and bone-grafting materials can be used to fill in the space between the elevated membrane and the maxillary sinus floor. This concept of MSFE was introduced by Tatum in 1977 [2]. A MSFE can be performed with a lateral or a crestal approach according to the method of accessing the Schneiderian membrane
