Patient Specific Plates for Mandible (PSPM) available

West Chester, Pennsylvania – DePuy Synthes CMF (Craniomaxillofacial), a leader in skeletal and soft tissue repair and reconstruction and part of the DePuy Synthes Companies of Johnson & Johnson, announced the launch of Patient Specific Plates for Mandible (PSPM), new plates that are customized based on surgeon specifications and individual patient anatomy.  

The DePuy Synthes CMF PSPM is the latest addition to the company’s TRUMATCH CMF, a portfolio of preoperative planning services, intraoperative tools, and patient-specific devices designed to help surgeons achieve their goals of accuracy, efficiency and patient care.

“PSPM gives the reconstructive surgeon greater control over plate design and screw placement which assists in planning of future dental restoration, ultimately leading to a more individualized reconstruction,” said Matthew J Bak, MD, an ENT-otolaryngologist and assistant professor at Eastern Virginia Medical School, Norfolk, VA, who was one of the first surgeons in the country to do an operation with the TRUMATCH CMF PSPM. 

The DePuy Synthes CMF PSPM includes a range of customizable design features that the surgeon can select before surgery including plate thickness and shape, and screw hole locations, pattern, and angulation. DePuy Synthes CMF engineers then design and manufacture the plate to the pre-planned patient anatomy. The plate is 3D milled from a solid block of titanium to its final shape and is never bent. This eliminates the need for plate bending in the operating room, which can induce mechanical stress and increase the potential for plate breakage. 

In addition, the DePuy Synthes CMF Patient Specific Plate for Mandible is optimized for use with PROPLAN CMF surgical guides. These guides have integrated drill guides for creating the bone holes, which are designed to align with the plate holes to facilitate transfer of the surgical plan to the operating room.  Anatomic bone models may be created from original patient CT scans or to the planned outcome, to provide tactile and visual representation of the surgery to enhance patient understanding.

The DePuy Synthes CMF Patient Specific Plate for Mandible is available in 2.0mm and 2.5mm thick profiles. Both these profiles have improved fatigue life over the company’s 2.5mm MatrixMANDIBLE flat plates, and the 2.0mm thick plates offer greater strength with lower profile, as compared to the 2.5mm MaxtrixMANDIBLE flat plates.
