OrthoTiN TMJ Device Description

OrthoTiN Patient Specific Joint Replacement System

The OrthoTiN TMJ system is designed with focus on matching patient unique anatomy. The implants geometry is based on the 3D skull model that is generated from the CT Scan of the specific patient. OrthoTiN Prosthesis are intended to provide a custom bone fitting surface replacements for the joint maintaining maximum bone stock. The prosthesis are divided into a ramus and fossa component. The Ramus component is constructed from a single piece of titanium bar stock and is used to replace the condylar head while being secured to the lateral side of the mandible. In order to provide a durability for articulating surface of the implant, a titanium nitride (C-TiN-C) surface coating is applied to the entire component. The fossa is composed of solid titanium alloy featuring eminence flange and a ultra-high molecular weight polyethylene (UHMWPe) bearing insert to replace the glenoid fossa and articulate with the ramus prosthetic condylar head. Each prosthesis is individually fabricated to the unique anatomy of the patient. Customizing the implant fit allows for excellent adaptation to these discrepant features providing maximum fixation and optimum function of the TMJ joint.
