Animal experiment: Histological analysis of the LPM reattachment2258again indicating a possible improper antero-posterior positioning of the implant, resulting in a 500-1900µm gap between the mandible and the implant. Throughout the rest of the sample, dense cortical bone is found in between the several scaffolds. Both samples show multitude of haversian canals and osteocytes, with bone remodelation, indicating viable osseous tissue. Whereas the first sample centrally contains hematopoetic tissue, the second is far more cortically organized, with only 2 small central fields with hematopoetic tissue. This can be explained due to the section being obtained just below the level where the ostectomy was performed and thus corticalization has occurred since.Fig. 4: Overview of the implant scaffold with enthesis.
