Conventional ultrasonic osteotomy in open maxillary sinus augmentation

Implantologia Stomatologiczna. 2011 PSI Implant Dentistry. 2011; Issue 03 Periodoncia y Osteointegración. 2010; Volume 20

ABSTRACT

We present a fully documented case of maxillary sinus lift where we employ conventional rotary osteotomy in combination with ultrasonic osteotomy, this being performed with a conventional descaling apparatus.

A male patient, 53 years old, non-smoker and with no relevant medical history, visits our clinic requesting implant treatment to restore several edentulous segments. In the left posterior superior edentulous segment we observe little residual bone height, so it was decided to perform an open maxillary sinus lift with deferred implant placement as it was considered not possible to ensure good primary stability of all implants.

Detachment of the sinus membrane is performed manually with specific curettes, which ensures sufficient height to achieve future placement of implants and is filled with xenografting MG Osteodrive (Mozo-Grau. Valladolid, Spain), covering the surgical window with a resorbable membrane, MG Reguarde (Mozo-Grau), fixed with two titanium pins, and repositioning the flap with 4-0 monofilament suture. After waiting for eight months and performing a control an x-ray, the edentulous segment is addressed again with a conservative incision and MG InHex implants are placed.

Summary: Open maxillary sinus lift is one of the complementary techniques most commonly used in Implantology, with the perforation of the Schneider membrane being the most frequent intraoperative complication. In order to reduce its incidence, whilst not prolonging surgery time, the combined use of osteotomy with rotary instruments in conjunction with ultrasonic osteotomy performed with a conventional descaling apparatus is a technique which is safe, effective and with a very conservative cutting line.
