A new design of Titanium dental implant, coated with Titanium oxide and with a Hydroxyapatite apex, was experimented in a Beagle dog's jaw for one year to evaluate the biocompatibility of the materials used and the biomechanical efficiency of the design. The explanted prosthesis and the surrounding bone were embedded in methylmethacrylate resin and the sections observed under Scanning Electron Microscopy (SEM), with an X-ray microprobe to check the interface with bone and the occurrence of ionic release. The results showed that the pin was well accepted by the bone. New bone grew on the metal surface developing a mechanical bond with the prosthesis. No ionic release of the metal was seen.
一种新型钛牙种植体，表面涂有氧化钛且顶端为羟基磷灰石，在比格犬的颌骨中进行了为期一年的实验，以评估所用材料的生物相容性和该设计的生物力学效率。将取出的假体和周围的骨头嵌入甲基丙烯酸甲酯树脂中，并在扫描电子显微镜（SEM）下观察切片，同时使用X射线微探针检查与骨头的界面以及离子释放情况。结果表明，种植体被骨头很好地接受。新骨在金属表面生长，与假体形成了机械性结合。未观察到金属的离子释放。
