Crestal approach for maxillary sinus augmentation procedure using reamer mediated crestal sinus floor elevation with simultaneous implant placement is introduced as a new technology, instruments and surgical technique to help clinician ensure the best result with non invasive technique and satisfy the patient expectations. Although there is still controversy regarding the necessity of simultane...

BACKGROUND The transcrestal approach with osteotomes is a commonly applied and predictable technique for maxillary sinus floor elevation. However, Schneiderian membrane perforation is a common and often inevitable intraoperative complication. Recently, the use of balloons has been proposed to reduce the risk of sinus membrane perforation and to facilitate the surgical technique. The aim of this...

PURPOSE The aim of the present study was to perform a finite element (FE) analysis of a modified sinus elevation procedure involving additional implantation of a cortical bone graft block for stabilization of an implant. A secondary aim was to compare the modified sinus augmentation with the standard technique and to determine whether the FE model to replace a dental implant can be simplified i...

In the atrophic posterior maxilla, successful implant placement is often complicated by the lack of quality and volume of available bone. In these cases, sinus floor augmentation is recommended to gain sufficient bone around the implants. Sinus elevation can be performed by either an open lateral window approach or by a closed osteotome approach depending on available bone height. This case ser...

PURPOSE A novel technique for transcrestal guided sinus lift elevation (TGSL), is described underlining the step by step surgical protocol. MATERIALS AND METHODS TGSL modified osteotome technique was planned by the NobelProcera(®) Software Planning Programm (Nobel Guide, Nobel Biocare AB) and performed by stereolitographic template. The depth of the planned osteotomy was determined precisely ...

There are different techniques for sinus lifting and augmentation; the factors that contribute to the survival rate of sinus augmentation and dental implant placement are still the subject of discussion. Sinus floor elevation is commonly used in cases where alveolar bone resorption has led to insufficient bone height for the placement of dental implants.

Maxillary sinus membrane perforation is the most common complication that occurs with sinus elevation augmentation surgery. A technique using a slow resorbing type I collagen membrane for repair of large and complete sinus membrane perforations is described. The biocompatibility and semirigid structural integrity of this membrane, along with external tack fixation, allows for optimal membrane s...

PURPOSE It was the aim of the present prospective study to quantify the gain in height of implant sites by endoscopically controlled osteotome sinus floor elevations (ECOSFE) with simultaneous implant placement and to report the number of sinus membrane perforations. MATERIALS AND METHODS From October 1999 to December 2000, of 92 sinus floor elevations, 18 were carried out endoscopically cont...
