    A:

    For maxillary sinus membrane elevation, there are two broad techniques: lateral approach or the crestal approach. Which technique is used, is of course, dependent on the case and the clinician's preferences and skills.

    That being said, when the crestal approach, sometimes also known as the osteotome technique or the Summers technique, was introduced, it offered several benefits, which can briefly be summarized as: Crestal approach is less aggressive than the lateral approach and the Crestal approach is a relatively simpler procedure and requires less time for wound healing that the lateral approach.

    Even considering the benefits of the crestal sinus approach technique, traditionally known as the osteotome technique, the technique also has several drawbacks, such as patient discomfort (ringing in ears), fracture of cortical bone, perforation of the membrane, and/or excessive bone cavity at the implant placement area. [1-4] .

    To overcome the shortcomings of the traditional osteotome technique, various new instruments and techniques have been developed over the years. The Neobiotech SCA kit replaces traditional osteotomes with specialized S-Reamer drills and stoppers. The unique drill design of the Sinus Crestal Approach Kit’s S-reamer head (800-1200rpm) leaves a thin bone disk between the Schneiderian membrane and the reamer for optimum protection, and it can be used in misaligned and septum cases. Furthermore, an assortment of stoppers control the drilling depth of the S-reamer from 2mm to 11mm,and the stoppers can be mounted on the bone spreader and inserter, thus making the kit a complete solution for performing a crestal sinus lift.

    Studies have shown that using the proper speed drill, along with the specialized s-reamers of the SCA, allows for quick and safe sinus membrane elevation, even at the septum area, reducing the risk of sinus membrane perforation.
