Animal experiment: Radiological analysis of the LPM reattachment1997between the implant and the bony surface (limited in our experiment). In the absence of good initial stability, successful osseointegration between the implant and its bony contact surface will be severely limited.(33)This was a significant limitation of our experiment, because it was impossible to prevent the sheep from performing laterotrusive movements using their LPMs. Activation of this muscle can create micromovements between the enthesis attachment and the implant scaffold and result in insufficient stability. This relationship seems relevant to three out of five of the sheep. Interconnecting heterotopic ossification (HO) was found around the lateral sides of both the fossa and mandible, which possibly resulted in additional stabilization between the LPM and implant. However, this finding was not present for the other two sheep that had (partial) bony reattachment of the LPM enthesis, no displacement of the fossa, nor any heterotopic bone formation (Table 5).Table 5: Fossa and ramal component positioningSheep # Ramal component Fossa component3520 Normal Normal8087 Normal with lateral incapsulation Normal with heterotopic bone formation2177 Normal Latero-inferior displacement with heterotopic bone incapsulation5158 Normal with lateral incapsulation Infero-dorsal displacement with heterotopic bone incapsulation2549 Normal Normal4249 Normal Normal0032 Normal Normal7998 Normal Latero-inferior displacement with heterotopic bone incapsulation4246 Normal Normal1724 Normal Normal4248 Normal with lateral incapsulation Latero-inferior displacement with heterotopic bone incapsulation8787 Normal Normal4473 Normal Normal0075 SHAM SHAMNikolas de Meurechy NW.indd 199 05-06-2024 10:14
