Achieving Predictable Hydraulic Sinus Condensing Using an Innovative Functional Sinus Implant: A Case Report.

Compend Contin Educ Dent 2020 May;41(5):278-283

President, Dental Implant Institute, Las Vegas, Nevada; Fellow and Diplomate, International Congress of Oral Implantologists.

Inadequate alveolar bone height/volume and sinus anatomy can complicate the predictable placement of conventional implants and subsequent restoration in posterior maxillary sites. A variety of sinus lift and vertical bone height augmentation materials and techniques have been utilized for this purpose; however, generally they are clinically challenging, demand well-trained surgical proficiency, and require the use of multiple armamentaria. Simultaneously, clinicians must meticulously handle the sinus membrane to achieve elevation without perforation, attain successful bone grafting, and ensure predictable implant osseointegration.
