摘要

用大鼠研究了羟基磷灰石颗粒植入后牙向颌段的迁移。为了防止过早接触陶瓷颗粒，在10天大的时候，将动物的牙齿细菌完全去除。由于牙齿的生理迁移，牙根与神经-骨复合体的接触具有有害的影响。鉴于这些发现，在牙根附近种植颗粒状羟基磷灰石是不可取的。

[Physiological tooth migration in hydroxyapatite grafts with bony regeneration. Animal study].

Tooth migration into jaw segments where granular hydroxy apatite had been implanted was studied in rats. To prevent premature contact with the ceramic granules, tooth germs were completely removed in the animals at the age of 10 days. Tooth root contact with the ceramo-osseous complex as a result of physiological tooth migration had deleterious effects. In the light of these findings the implantation of granular hydroxy apatite in the vicinity of tooth roots is not advisable.
