Summary:
Computed tomography (CT) and the application of CT-based guided implant surgery allow clinicians to
provide enhanced precision and accuracy in implant surgery. Because of the difficulty in transferring a
patient’s often complex anatomic sinus configurations, as viewed on a preoperative CT scan, into precise
osteotomy cuts at antral bone graft surgery, a prototype cutting guide was developed. The surgical guide
was developed through the use of CT imaging and the stereolithographic process to precisely position the lateral window, facilitating schneiderian membrane elevation. This report demonstrates the step-by-step method to
perform precise guided sinus window preparation using computer software and a stereolithographically
generated surgical guide.

The Effect of Piezoelectric Use on Open Sinus Lift Perforation: A Retrospective Evaluation of 56 Consecutively Treated Cases From Private Practices
The lateral window approach to maxillary sinus augmentation is a well-accepted treatment option in implant dentistry. The most frequent complication reported with traditional techniques has been the perforation of the Schneiderian membrane, with erforation rates ranging from 11% to 56%. The purpose of this retrospective, consecutive case series from two private practices was to report on the rate of Schneiderian membrane perforations and arterial lacerations when a piezoelectric surgical unit was used in conjunction with hand instrumentation to perform lateral window sinus elevations.

Maxillary Sinus Membrane Repair: Update on Technique for Large and Complete Perforations
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 stabilization and maintenance. (Implant Dent 2008;17:24–31)

Crestal Sinus Elevation Utilizing a Hydrodynamic Piezoelectric Approach
This surgical clinical video demonstrates thorough CBCT planning and execution of sinus elevation utilizing a crestal approach in a molar site utilizing a hydrodynamic piezoelectric approach. Sinus elevation, osseous grafting and utilization PRGF fibrin membrane are demonstrated in detail. In addition, management of achieving adequate primary stability in simultaneous implant placement is also demonstrated.

Sinus Floor Elevation: A Clinical, Radiographic and Histologic Overview
This presentation and imbedded HD videos will highlight the important aspects of the Sinus Lift procedure and how to increase the success rate while minimizing complications.
An overview of the procedure with detail radiographic planning and follow up outcomes will be displayed and histoligical results highlighted to gain an appreciation of the timing of bone fill and when you can place and load implants in the augmented sinus. Complications and their management will be equally covered with an impetus on case and patient management and follow up care. Common medications and techniques for each procedure will be noted.

Tissue Engineering and Platelet Derived Growth Factors: Evidence Based Therapy
Platelet derived growth factors are now routinely utilized in reconstructive therapy. This presentation describes very detailed and evidence based guidelines for clinicians interested in enhancing their abilities in tissue engineering, especially as it relates to bone augmentation. Specifically, while successful bone augmentation requires the standard surgical parameters of space maintenance, low pressure on the grafts and tension-free flap closure, optimization of this goal requires management and enhancement of the local biological conditions with growth factors. Towards that end, platelet concentrates through the constant release of growth factors are able to promote and enhance new vascularization, provide plasma protein, normal lipidemia, as well as increased collagen and fibrin activity.
