Implant placement in the posterior maxilla is often complicated by limited bone height and the close proximity of the sinus. The Crestal Approach Sinus Kit (CAS-Kit) addresses these challenges with a comprehensive instrument set designed for safe, minimally invasive crestal sinus augmentation.
Why It Matters for Dental Surgeons?
The CAS-Kit offers a refined crestal sinus lift technique – faster, safer, and less traumatic than the lateral approach. Dentists benefit from predictable outcomes, reduced operative complexity, and enhanced patient safety in challenging posterior maxilla cases. All instruments are housed in a robust, neatly labeled hard case, facilitating sterilization, organization, and quick access during surgery.
The rounded cutting edge drill design decreases the likelihood of Schneiderian membrane perforation during sinus floor penetration.
The inverse conical drill tip allows effective application whether the sinus floor is flat, inclined, or near septa.
A uniquely designed membrane lifter provides a sealed osteotomy, using saline hydraulic pressure to safely elevate the sinus membrane.
Bone chips generated between the drill blades are collected for use in grafting, supporting autogenous augmentation strategies.

In the video below, you’ll get a clear overview of the kit, its key components, and a step-by-step workflow designed for efficient handling. Whether you’re looking to improve predictability, simplify your protocol, or understand indications and limitations, this short explanation helps you evaluate how the CAS-Kit fits into your treatment routine.
Unlike the lateral window technique, the crestal approach is minimally invasive. The CAS-Kit enables sinus elevation through the alveolar crest, reducing surgical trauma, chair time, and patient discomfort.
The CAS-Kit is suitable when the residual alveolar bone height is typically 5–8 mm. It helps clinicians gain additional vertical height for safe implant placement.
The kit can also be used with many other major implant systems, depending on the clinical case, which is one of the main advatages of the Kit.
The CAS-Kit can be complemented with bone grafting materials (such as A-Oss or Q-Oss) and resorbable membranes to stabilize the graft material after sinus elevation.
