Background & Aim: The use of a specially designed drill and nanohydrxylapatite paste can achieve minimally invasive transcrestal hydraulic sinus floor elevation without the use of an osteotome or a mallet. The aims of this retrospective study are to describe the technique and present 3years outcomes .

Methods: A specially designed drill (Sinusjet) creates the osteotomy. Thanks to its inner irrigation system, physiological liquid flows through maxillary bone during drilling, unsticks the sinus membrane before the drill penetrates into the sinus cavity, and begins to elevate the sinus floor membrane. The drill backflowing security system ensures a safe intrabony working pressure. The nanocrystalline hydroxyapatite paste (Ostim) used as augmentation material contributes to further membrane unsticking and elevation. Implant survival rate, grafting material loss, sinus membrane perforation, post-operative complications, patient outcome and level of intraoperative and postoperative patient comfort using a visual analogue scale were followed .

Results: 130 transcrestal sinuslifts were performed in 104 patients with simultaneous placement of 194 implants . The mean follow-up period was 3 Years ± 9 months . The mean height of the residual alveolar process was 4.5 +/- 1.6 mm . A mean sinus floor elevation of 8.5 mm +/- 2.7 mm was performed ( P < 0.0001). There were 4 sinus membrane perforations and six early implant loss (survival rate of 97 % ). No post-operative complications nor graft lost were reported. 96,4% of the patients experienced no or minimal discomfort during surgical procedure and post-operative healing period .

Conclusion: Within the limits of this retrospective study, this minimally invasive hydraulic transcrestal procedure appears safe and predictable. It is both patient friendly with very low discomfort, and practitioner friendly with a simple and fast procedure . Observations on a larger number of patients and on a longer period is needed to support the excellent clinical performance seen so far.
