Sinus Floor Augmentation With Simultaneous Implant Placement Using Choukroun’s Platelet-Rich Fibrin as the Sole Grafting Material: A Radiologic and Histologic Study at 6 Months
Sinus augmentation with simultaneous implant placement without bone graft material is a hotly debated technique. This technique could be improved and secured by the use of an autologous leukocyte-and platelet-rich fibrin (PRF) (Choukroun’s technique) concentrate. The objectives of this study were to assess the relevance of PRF clots and membranes as the sole filling material during a lateral sinus lift with immediate implantation using radiologic and histologic analyses in a case series.

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)

Managing Complications and Challenges in Sinus Augmentation
This presentation and surgical video demonstrates the corrective management of multiple infection and sinusitis following an earlier attempt at sinus augmentation. Dr. Sohn demonstrates the step-by-step clinical approach to this challenging sequelae that implant surgeons working in the posterior maxilla must be prepared for.

Manejo de Complicaciones de implantes en la Zona Posterior de la Maxila
El Dr Alvaro Ordonez demuestra el manejo de una complicacion clinica consistente en la necesidad de remover implantes dentales uno en el seno maxilar izquierdo y otro en el complejo osteomeatal derecho con la reparacion inmediata de la membrana Schneiderian utilizando dos tecnicas diferentes de reparacion de perforaciones de la membrane Schneiderian y con la consecuente colocacion de materiales de injerto oseo para elevacion y aumento de seno maxilar.

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.

Prevention and Treatment of Post-Operative Infections After Sinus Elevation Surgery
Maxillary sinus surgery is a reliable and predictable treatment option for the prosthetic rehabilitation of the atrophic maxilla. Nevertheless, these interventions are not risk-less of postoperative complications with respect to implant positioning in pristine bone. The aim of this lecture is to report the results of a clinical consensus of experts (periodontists, implantologists, maxillofacial surgeons, ENT, and microbiology specialists) on several clinical questions and to give clinical recommendations on how to prevent, diagnose, and treat postoperative infections.

Digital Dynamic & Static Solutions
Partial Extraction Therapy and crestal sinus augmentation have changed the methods of implant planning and execution. Preserving both hard and soft tissue has propelled these concepts to innovative. Until recently the use of dynamic and static guidance has been delayed. The objective of this presentation is to understand the need for digital guidance and explores avenues to accomplish a digitally based workflow and execution fr the subsequent procedures.
