人体标本的尸检是评估骨内种植体表面的相对相容性和长期成功的一个极其重要的方面。对使用 85 个月后的 5 个商业纯钛螺钉型下颌种植体和使用 38 个月后的 2 个羟基磷灰石 (HA) 涂层上颌种植体的骨-种植体界面进行了检查。在患者死亡时，所有植入物均处于稳定状态。下颌种植体与骨的平均接触率为 65%，上颌种植体平均为 47%。 HA 涂层在某些区域已与上颌种植体分离，并游离在周围结缔组织内或被内陷的龈沟上皮包围。 HA 涂层和钛种植体表面的骨接触排列和模式似乎有所不同。
Postmortem examination of human specimens is an extremely important aspect of evaluating the relative compatibility and long-term success of endosseous implant surfaces. The bone-implant interface of 5 commercially pure titanium screw-type mandibular implants after 85 months of service and 2 hydroxyapatite- (HA) coated maxillary implants after 38 months of service were examined. All implants were stable at the time of the patient's death. The mandibular implants had an average of 65% contact with bone and the maxillary implants had an average of 47% contact. The HA coating had separated from the maxillary implants in some areas and was free within surrounding connective tissue or surrounded by invaginating sulcular epithelium. The arrangement and pattern of bone contact appeared different between HA-coated and titanium implant surfaces.
