Animal experiment: Radiological analysis of the LPM reattachment1917laterally from the implant and appeared to connect the mandible to the skull base. A fracture of this heterotopic bone prevented joint ankylosis. This fracture was likely due to continued movement of the mandible. One of the two sheep scanned at 6 months after surgery, # 2177, had a bony connection between the enthesis and the mandible, as was found in the previous two sheep. However, there was no bony connection between the enthesis and the scaffold. There was heterotopic bone formation around the lateral side of both the ramal and the fossa components. There was also a slight latero-inferior displacement of the fossa component, showing non-integration onto the articular tubercle. The scan of the second sheep, ewe 2549, revealed good positioning of both TMJR components, but there was no enthesis reconstruction with osseous or fibrotic characteristics.
