本文通过动物实验对比观察纵横两种软组织切口对牙—骨块愈合、并发症的发生及血运重建情况的影响。结果两种术式创口及牙—骨块的愈合均良好,无明显并发症。组织病理学检查,两种术式术后12周均可见牙髓、牙周血管扩张,墨汁颗粒充满血管,牙髓血管丰富,冠髓造牙本质细胞增生,牙髓已基本恢复活力。本组实验体会横行软组织切口术野清晰、操作方便、创伤小、出血少、省时省力。为临床选择较适用的横行软组织切口提供了较为可靠的实验依据。
In this paper, animal experiments were compared to observe the vertical and horizontal incision of two kinds of soft tissue on the healing of teeth - bone, the incidence of complications and revascularization situation. Results The two types of wounds and teeth - bone healing were good, no significant complications. Histopathological examinations showed that dental pulp could be seen at 12 weeks after operation in both groups. Periodontal blood vessels were dilated, blood grains filled with ink particles, abundant vascular blood vessels, proliferation of essential cells in coronal pulp and restoration of viability of dental pulp. This group of experiments experience rampant soft tissue incision surgery field is clear, easy to operate, less trauma, less bleeding, saving time and effort. It provides a more reliable experimental basis for the clinical choice of transverse soft tissue incision.
