文题释义:
口腔软组织缺损模型:利用标准化的直径为5 mm的组织环切钻在动物硬腭前部中份制备软组织缺损,不仅符合动物造模的标准一致性原则,还可以避免单纯利用手术刀片、量尺进行术区制备可能引起的误差及操作不便,简化了实验操作,节约了手术时间,并使得该动物模型稳定性相对更好。
新西兰大白兔:具有性情温顺,抗病性及适应性强、饲料利用率高、易于管理及价格经济等优点,加之其硬腭黏膜与人口腔软组织的组织学结构类似,在其上制备软组织缺损能更好地接近并反映人类口内软组织创伤修复的一般规律。


 

背景:在口腔种植临床,对术区软组织缺损修复方法及材料的研究一直在深入。而通过建立可靠的实验动物口腔软组织缺损模型,会对该领域的探索研究产生积极的深远影响。
目的:实验旨在建立一种兔口腔软组织缺损动物模型,以供对口腔软组织缺损修复治疗进行深入的研究。
方法:在18只3月龄雄性新西兰兔的硬腭前部中份,分别距上颌门齿、左右硬腭黏膜边缘2 mm处以直径为5 mm的组织环切钻制备圆形软组织全层缺损。分别于建模后3,7,14,21,28,56 d对创面进行形态学和组织学观察。
结果与结论:①创面形态:建模后3,7 d,创口炎症反应明显;随着时间推移,炎性反应消退,伤口逐渐愈合。在建模后21,28,56 d可见明显瘢痕形成;②创面组织学变化:在伤后3,7 d,炎细胞大量浸润,组织坏死面积较大,建模后7 d后,随着结缔组织增殖和新生毛细血管的广泛形成,伤口逐渐塑形完整;③结果说明:实验成功构建口腔软组织缺损模型兔,符合创伤愈合的生理规律和人类口腔软组织缺损愈合特点。

Abstract:

BACKGROUND: In clinical, the research on the method and the material of the soft tissue defect of the operation area has been in depth. It will have a positive impact on our exploration and research in this field through the establishment of reliable experimental animal oral soft tissue defect model.

OBJECTIVE: To establish a rabbit model of oral soft tissue defects for oral treatment of soft tissue defects in-depth study.
METHODS: Eighteen 3-month-old male New Zealand rabbits were enrolled. A tissue ring cutting drill of 5 mm diameter was used to prepare round full-thickness soft tissue defects in the front part of the hard palate and, respectively, from the back of the maxillary incisors, about 2 mm from the hard palate mucosal edge. Morphology and histology were observed at 3, 7, 14, 21, 28 and 56 days after model establishment. 
RESULTS AND CONCLUSION: (1) Morphological observation: After 3 and 7 days, the wound’s inflammatory reaction was obvious. As the time goes, the inflammatory response subsided, the wound gradually healed. Scar formation was observed at 21, 28 and 56 days after surgery. (2) Histological observation: 3 and 7 days after injury, many inflammatory cells were infiltrating, and tissue necrosis area was larger. At 7 days after surgery, with the extensive formation of connective tissue proliferation and new blood capillaries, the wound gradually shaping completely. (3) Results indicated that a rabbit model of oral soft tissue defects was successfully established, which was in line with the physical laws of wound healing and the characteristics of human oral soft tissue defects healing.
