Depth gauge for matrix mandible system
Fig 1 Depth gauge for matrix mandible system In constantly improving the functionality and design of hardware that is available to the surgeon, it is worthwhile taking a closer look at instrumentation. The new depth gauge for the matrix mandible system is used to measure the depth of holes for any screws from 2.03.0 mm in diameter and up to 45 mm in length. It is applicable for all trauma and reconstructive procedures in the mandible where bicortical screw fixation is compulsory.
Although designed as part of the matrix mandible set, it can also be used with any other screw system. This device is made of stainless steel and radel (polyphenylsulfone) making it lightweight, ergonomic, and durable. In addition, it offers better readability than the former depth gauge because of reduced surface glare. It is now a two-piece (instead of a three-piece) device, facilitating assembly and cleaning and has a sharp and bent hook tip to consistently grab bone. The sliding mechanism has been improved so it remains stationary when not pushed.
