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

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. The hydraulic sinus condensing (HSC) technique via the osteotomy site is designed to be less invasive than conventional sinus lift techniques, reduce trauma to patients, improve implant osseointegration into grafted alveolar bone, prevent sinus membrane perforation, and enhance the overall efficiency of the associated surgical process. This article briefly reviews the evolution of sinus lift and posterior maxillary implant insertion procedures and presents a case in which the HSC technique and a uniquely designed sinus implant were used.
