This study evaluated the effects of calcium phosphate ceramics, hydroxylapatite, and tricalcium phosphate implants on tooth eruption and development. Forty kittens, three to four months of age, had their primary right second and third mandibular premolars extracted and the sockets packed with either hydroxylapatite, tricalcium phosphate, autogenous cancellous marrow, or nothing. The results of this study indicated that the use of a nonresorbable hydroxylapatite for grafting resulted in impediment of tooth eruption and distortion of crown development. This was in contrast to the tricalcium phosphate, which had minimal effect on tooth eruption and development.
本研究评估了磷酸钙陶瓷、羟基磷灰石和磷酸三钙植入物对牙齿萌出和发育的影响。40只3至4月龄的小猫，拔除其右侧下颌乳第二和第三前磨牙，并将牙槽窝分别用羟基磷灰石、磷酸三钙、自体松质骨髓填充，或不进行填充。本研究结果表明，使用不可吸收的羟基磷灰石进行移植会阻碍牙齿萌出并导致牙冠发育畸形。这与磷酸三钙形成对比，磷酸三钙对牙齿萌出和发育的影响最小。
