Crestal Sinus Augmentation: A Simplified Approach to implant Placement in the Posterior Maxilla
Douglas F. Dompkowski, and Gregori M. Kurtzman
Introduction
In the realm of dental implantology, crestal sinus augmentation stands as a pivotal technique for ensuring successful implant placement in the posterior maxilla. This article delves into a streamlined approach that leverages the innovative CAS-Kit. Designed to enhance precision and reduce procedural complexities, the CAS-Kit emerges as an invaluable tool for clinicians. By offering a detailed exploration of this method, we aim to equip dental professionals with the knowledge and confidence to achieve optimal outcomes in sinus augmentation procedures.
Purpose
To introduce a crestal approach sinus augmentation procedure using safe side/end cutting drills with vertical stoppers combined with hydraulic pressure for membrane elevation
Materials
CAS-Kit
Evaluation
1. Initiation of procedure is with a 2 mm twist drill with stopper set for the desired osteotomy stopping 1 to 2 mm inferior to the sinus floor.
2. The drill stopper is selected and placed upon the CAS-Drill as the site is prepared to the depth of available bone inferior to the maxillary sinus.
3. Autogenous bone is harvested from the drill to mix with graft material to seed with osteoblastic cells and other progenitors of bone.
4. The probe is used to check the depth of the osteotomy and sinus elevation is initiated via the hydraulic lifter.
5. Sterile saline is introduced to the sinus cavity to lift the membrane and grafting material packed into the osteotomy and pushed into the sinus.

Discussion:
This technique may be utilized for single sites or adjacent sites wherein the clinician may perform sinus lift procedures with increased safety and without the risk of membrane tear.
Conclusion:
The CAS-Kit provides an alternative, risk free method for sinus lift when compared to the traditional methods of lateral wall or crestal augmentation via osteotome.
