OneCAS – Osstem Srbija

Benefits of the OneCAS Kit

The Osstem OneCAS Kit is a state-of-the-art, guided sinus lift solution that merges the benefits of the CAS (Crestal Approach Sinus) methodology with Osstem’s OneGuide digital system. It enables clinicians to pre-plan implant position, depth, and angulation before surgery and execute crestal sinus elevation with precision and safety.

Why It Matters for Clinicians
Maxillary sinus anatomy presents a challenge for posterior implant strategies—especially when bone height is limited. The Osstem OneCAS Kit empowers clinicians to:

Increase surgical safety, by minimizing membrane perforation with precision drills
Ensure consistent outcomes, through digital planning and guided execution
Enhance onsite efficiency, by consolidating planning, guide fabrication, and surgery into a streamlined workflow
Improve patient comfort, with less invasive sinus access and predictable grafting results

This leads to elevated confidence, reduced chair time, and better long-term restorative success.

Key benefits

Digital Preoperative Planning

Utilize CT and oral scan data to define implant length, position, and angulation—resulting in a patient-specific surgical guide.

Reduced Risk of Sinus Membrane Perforation

Features an inverse conical drill tip with a rounded edge to preserve the Schneiderian membrane and allow autogenous bone collection.

Controlled Drilling with Stopper System

Offers stopper options in 1 mm increments for safe penetration toward the sinus floor—compatible with 7 mm and 10 mm drills (Ø5.1 / Ø5.8 guide holes).

Guided OneGuide Template for Precision

Use the OneGuide stent for accurate drilling trajectories, ensuring safety and accuracy during sinus floor access.

Integrated Hydraulic Lift & Grafting Workflow

After template removal, proceed with hydraulic sinus membrane elevation, followed by bone grafting and implant insertion.

Complete Surgical Kit in Labeled Case

Includes drills, stoppers, hydraulic lifter, bone carrier, depth gauge, torque wrench, and condenser—all housed in an organized kit.

Fabricate surgical template for drilling accuracy

Implant placement planning

Define implant position and specification

Delivering advanced surgery techniques with our combined OneGuide computer-guided surgery system with the unique CAS Drill design
Determine the implant length, position and angulation before the surgery

CAS Drill: Safe inverse conical drill and round cutting edge

Bone chip is created when the sinus floor is lifted

Minimizes the risk of sinus membrane perforation

The inverse conical drill tip and round cutting edge collect autogenous bone while drilling
When the drill stopper seats completely, the sinus floor is lifted without tactile sensation of the membrane alone
The unique drill features prevent excessive pressure on the membrane
