BACKGROUND: The aim of this study was to present a case series treated with an atraumatic procedure for maxillary sinus lift by crestal approach. This technique avoids the use of classical osteotomes, thus decreasing complications due to percussive and vibratory forces.
METHODS: Three cases of partial edentulism in the distal maxillae with inadequate bone volume are treated by using SinCrest® procedure (Meta, Reggio Emilia, Italy).
With the guide of surgical templates, the sinus lift was performed, and implants were placed during the same procedure. After 6 months an X-ray was taken to check the success of the operation.
RESULTS: SinCrest® allows the operator to advance progressively, maintaining the correct axis for implant placement. The plane tip of drills prevents accidental perforations of Schneiderian mucose, and the stops, available in different lengths, avoid the overtreatment. The manual screwing of SinCrest® osteotome ensures precision during the cortical approach, while the built-in probe allows to check residual strength of sinusal floor, making sure that the Schneiderian mucose is reached and lifted. This technique does not depend on the operator’s skills and decreases the onset of adverse effects due to the hammering with classical osteotomes. SinCrest® requires a small flap and osteotomy, which means less healing time and more comfort for the patient, both during and after the surgery.
CONCLUSIONS: SinCrest® is a valid alternative to other mini-invasive procedures for sinus lift in cases with a residual height bone of at least 5 mm, allowing an atraumatic, safe and controlled operation.
