• Unique CAS-Drill safely and rapidly lifts the sinus membrane while drilling.
• Unique stopper system that prevents over drilling into the sinus cavity.
• Hydraulic Lift System that easily and safely lifts the membrane.
• New Bone Carrier System for transferring and filling bone graft materials.
• Simple and intuitive surgical system.
The unique component of the CAS kit is the CAS-Drill. The CAS-Drill is designed to safely and rapidly lift the maxillary sinus membrane from a crestal approach. The CAS-Drill can be used for either straight or tapered implants. It is optimised for insertion torque, initial fixation strength, and tactile feedback when using OSSTEM’s TA III Implants.
• CAS-Drill forms a conical bone barrier, protecting the membrane.
• The atraumatic design of the drill tip allows the user to perform sinus surgery even if the sinus floor is flat, inclined septum and inferior alveolar canal.
• The CAS-Drill tip has an inverse conical shape. This shape will form a conical bone chip when drilling, which assists with safely lifting the membrane. In addition, bone particles generated when drilling discharge upwards, producing a Membrane Auto-Lift Function.
• Option to drill from low speed to high enabling the harvesting of autogenous bone at low speed.
• Unique stopper system (in 1mm increments) that prevents over drilling into the sinus cavity.
• Final drill diameter selected according to fixture diameter and bone density, independently of straight or tapered fixture type.
The drill is designed with four blades, which reduces deflection off the bone and the straight sides dampen vibrations.
2.0 Guide Drill• Marking drill to mark fixture insertion location.
• Used to remove side wall
of tooth extraction with its
blade formation.
• Marking on apex at 2mm.
CAS-Drill• Comes in six diameters: 2.8/3.1/3.3/3.6/3.8/4.1
• Allows a 13mm Fixture to be implanted.
• Drilling is dependent upon the Fixture diameter
and the bone density.
• Drilling speed ranges from low speed to high
speed (800rpm), allowing flexibility during surgery.
• Experienced: 800rpm
• Beginner: 400 to 600rpm
• Is recommended irrigation with saline solution.
• Can be used up to 50 times depending on the type of bone.
Depth Gauge• Measures the thickness of the remaining bone.
• The atraumatic tip can be used to confirm membrane lifting.
• Can be used with the Stopper system.
• Caution: Do not use the Depth Gauge to lift membrane beyond 1mm.
Hydraulic Lifter• The Hydraulic Lifter uses normal saline to raise the membrane.
• Infuse 1cc or 3cc with a syringe.
• Required volume of saline solution to expand 3mm of the membrane, generally 0.2 to 0.3cc of saline solution is injected. Inject saline solution very slowly.
Contraindications:
• Not recommended for patients with inflammation of the maxillary Sinus (Sinusitis).
• Notrecommendedforpatients with complex morphology of the sinus floor (including the septum)
• Fill in bone material to the back of marking line on head part, separate gradually with bone condenser to fill inside of sinus completely, and repeat the procedure.
Bone Carrier• Used to fill bone graft materials inside sinus cavity.
• Fixes head part by tightening the back of body part.
• Head can be replaced (SNBCH30 or SNBCH35).
Bone Condenser• Used to fill bone graft materials inside sinus cavity.
• Fixes head part by tightening the back of body part.
• Head can be replaced (SNBCH30 or SNBCH35).
Hydraulic Membrane Lifter Tube
• Connect to hydraulic membrane lifter. • Code: SNMT
The CAS-Drill design is optimised for OSSTEM’s TS III Implants.
Use the table on the right to prepare for surgery.
There are a few things that need to be taken into consideration; the diameter of the implant, bone density into the sinus floor, and the necessary force for a stable implant. In the case of a general straight type implant, use a CAS-Drill that is 1mm smaller in diameter than that of the implant.
