Three-dimensional imaging analysis about affinity between jawbones and ultra thin-hvdroxv-apatite-coated implant

将超薄羟基磷灰石（HA）和纯纯钛（Ti）种植体植入犬下颌骨，利用组织标本和显微ct三维图像及时观察种植体表面和近表面部分的新生过程和骨融合形态的变化。并利用试产的差异管理软件对临床病例的骨结构变化进行分析。充填种植体后，动物实验3 ~ 24周，临床病例1年。对于病例中新增的活骨，不仅以种植体底板向上1/2的母底板骨表面为代表，而且以aHA膜表面为代表，如三周后用ham显微镜检查。在钛中，这种现象只出现在母地板骨的表面。在植入体表面，纤维连接组织进入。hha和Ti在种植体地板向下1/2无显著差异。与5周后的情况一样，种植体地板向上1/2的骨空间被HA完全封闭，新生骨添加在母地板骨表面。另一方面，这个空间不满足于新骨和纤维连接组织中的钛。虽然在三周后出现伪影是令人担忧的，但从各个角度的微ct视图的代表性例子可以捕捉到骨和植入体的边界。虽然在两个种植体的种植体地板向上1/2的骨间隙中承认上述损失，但这种趋势以ti表示。骨小梁型的形成在骨髓腔中被HA识别，它们与皮质骨相连。另一方面，它不在钛植入物的周围。在临床病例中，使用差异管理的试用软件计算骨变化区域对应的像素数。骨吸收和骨重塑之间的区别是困难的，但可以定量地指定骨变化区域。少

Ultrathin-Hydroxyapatite-coated (HA) and pure titaniumsimple (Ti) implantswere filied up in the jawbone of dogs, and a newly liveprocess and a change of the bone fusion form in and near surfaces part of implant were timelyobserved using the organization specimen and the micro-CT three-dimensional image. Moreover,the difference management software of the trial production was used to analyze a change of bone structure of theclinicalcase. After fillingimplant, itwas relatedfrom3weeks to24weeksduringtheanimal experiment,and for 1 year in the clinical cases. As for thenewly livebone addition in the case, not only the surface of the mother floor bone of implant floor upward 1/2 but also the surface of aHA filmwas recognized as the representative for example of amicroscopic examinationwith HAafter threeweeks. In Ti, this phenomenon presented on only the surface of themother floor bone. On the surface of implant, fibre-connecting-tissue entered. Therewas no difference in implant floor downward … More 1/2 betweenHA and Ti. As the case after 5 weeks, the bone space of implant floor upward 1/2 was closed with HA by perfection by the newly raw bone added on the surfaceof themother floor bone. On theother hand, this spacewasn't satisfiedwithTi in thenewly rawbone, and fibro-connecting tissue lay. Though it was apprehensive for the occurrence of artifact after three weeks, a boundary with the bone and implant body could be caught with a representative example of themicro-CTviews from all angles. Though abone loss was admitted in the bone space of implant floor upward 1/2 onboth implant, the tendencywas expressedwithTi. The formationof the trabecular patternwas recognized in the marrow cavity with HA, and theywere connected to cortical bone. On the other hand, it was not in the surroundings of Ti implant. In clinical cases, the pixel number corresponding to the bone change area was counted using a trial software of the difference management. A distinction between bone absorption and remodeling was difficult, but quantitatively could specify the bone change area. Less
