A comparison of solid root forms and particulate hydroxylapatite implanted into dog tooth extraction sites showed both types of implants to be well tolerated. Neither prevented postextraction bone resorption, but the particles were better able physically to maintain ridge height and width than the root forms.
对植入犬齿拔牙位点的实心牙根形态植入物和颗粒状羟基磷灰石进行比较,结果表明两种类型的植入物耐受性都良好。两者都不能阻止拔牙后的骨吸收,但颗粒在物理上比牙根形态植入物更能维持牙槽嵴的高度和宽度。
