SCA Kit
Sinus Crestal Approach Kit
A complete surgical kit for crestal sinus elevation — perforating the sinus inferior cortical wall and lifting the Schneiderian membrane without membrane damage or the need for mallet osteotome technique. The S-Reamer's uniquely designed blade structure forms a protective bone disk against the membrane, enabling safe, high-speed drilling at 1,200 RPM even in misaligned and septum cases.
What clinicians are saying
Real-world feedback from implantologists using the SCA Kit for crestal sinus elevation in their surgical practice.
"The SCA Kit has changed how I approach short residual bone cases. The S-Reamer drills at speed — you're not hammering an osteotome, so patient feedback is completely different. The bone disk that forms in the reamer head is what really makes the difference clinically: even when I've had the reamer touch the membrane directly in a septum case, there's been no perforation. It's built more confidence into what used to be a high-anxiety step of the procedure."
"CMI fixation was the concept that made me try the SCA Kit — getting engagement in all three bone zones from a crestal approach is something conventional osteotome technique simply doesn't achieve reliably. The stopper system makes sequential depth progression feel controlled and safe, and the whole procedure from initial drill to final implant placement follows a logical step-by-step sequence that's easy to train staff and residents on."
When to use the SCA Kit
Indicated for crestal sinus elevation in cases where residual bone height is insufficient for standard implant length — without the need for lateral window approach or mallet technique.
Safety · Speedy · Simple
Three design principles behind the SCA Kit — each directly addressing a clinical limitation of conventional crestal sinus elevation technique.
Safety
Bone disk shields the membrane
— even on direct contact
The S-Reamer's specially designed blade structure does not tear the sinus membrane even in direct contact. During drilling, bone chips fill the reamer head space and form a flat bone disk surface between the reamer and the membrane — providing an additional protective layer. This makes the SCA Kit safe to use in misaligned and septum cases where membrane contact risk is highest.
Speedy
High-speed drilling
— 1,200 RPM with irrigation
High-speed drilling of the S-Reamer at 800–1,200 RPM (with saline irrigation) enables safe and rapid perforation of the sinus inferior cortical wall without membrane damage. The 'S'-shaped blade design allows the reamer to cut the bone effectively at speed, removing the need for the slow, physically demanding mallet-and-osteotome technique and shortening the operative time significantly.
Simple
User-friendly design
— reduced technique-sensitivity
The SCA Kit provides a much easier and less technique-sensitive approach to sinus crestal elevation. Each component is purpose-designed for a specific step in the procedure sequence, the stopper system controls drilling depth in 1mm increments, and the kit uses a general rotary drilling method that any trained implant surgeon can perform without specialised mallet training.
Step-by-step procedure sequence
From initial osteotomy preparation through to final implant placement — each SCA Kit component performs a defined role in the crestal elevation sequence.
Initial Drill & Widening
Drill to 1mm shorter than residual bone height. Widen to final diameter based
on bone density. Do not reach within 1mm of the sinus membrane.
S-Reamer
Drill remaining bone to the sinus inferior cortical wall. Gently perforate the
cortical floor until opening is detected. Speed: 1,200 rpm with irrigation.
Depth Gauge
Confirm complete sinus floor opening by hanging gauge tip in the sinus wall.
Feel membrane with the flat end. Do not insert more than 1mm into sinus.
Bone Carrier
Insert bone graft into the osteotome site using the bone carrier (0.05cc per
insertion). Approximately 0.1cc of bone is needed to lift the membrane 1mm.
Bone Condenser
Push graft material to the sinus floor. Use the wide end for fine particulates
and the narrow end for coarse particulates.
Bone Inserter
Alternative method to push graft into sinus using the spiral bone inserter.
Connect stopper (residual alveolar bone height) and rotate at 80 rpm.
Bone Spreader
Spread bone laterally to reduce tension against the membrane. Connect stopper
and rotate at 50–80 rpm. Repeat after every 0.1cc of bone insertion.
Final Drill & Implantation
Freshen up the channel with a larger drill to remove excess graft material.
Place implant and obtain CMI fixation from the sinus inferior cortical wall.

S-Reamer diameter selection guide: For 1–3mm sinus insertion depth — Regular fixture: Ø2.4 · Wide fixture: Ø3.2. For more than 4mm insertion depth — Regular fixture: Ø2.8 · Wide fixture: Ø3.6. S-Reamer diameter is directly related to CMI implant diameter and must be selected carefully.
