The final solution mimics the movement of a spine that provides flexibility in controlled directions and rigidity at rest. The arm utilizes an acetal beam surrounded by a silicone overmold. The acetal beam provides the flexibility required, and through testing, holds up to the rigors of repeated usage.
The silicon overmold provides a simple, cleanable, durable surface. When combined, the arm provides a very natural, organic, and beautiful movement as it flexes to accommodate operating conditions. The Midmark Continental-Style Dental Delivery System provides maximum flexibility compared to existing solutions, via the unique, patent-pending spine of the whip arm.
