ABSTRACT
Objective:
To establishing model of anterior disc displacement(ADD) of temporomandibular joint(TMJ) by persistent inducement of traction through orbit.Methods:
The inferior and posterior walls of orbit of right side in 8 rabbits were exposed. The anterior part of disc was vertically passed through using a suture needle with an elastic rubber. The double strands of the elastic rubber was stretched forward from 7 mm to 16 mm and fixed in the hole drilled in the zygomatic arch bellow inferior orbit. The rabbits were killed 1,2,4 and 8 weeks after operation respectively, then both TMJs of each were resected. The paraffin sections were made and stained with hematoxylin & eosin.Results:
The mandible of the rabbits deviated to the left side with inclined attribution of incisors. The disc was displaced forward and the degree of ADD in the rabbits was similar.Conclusions:
The disc anterior displacement of temporomandibular joint can be induced by persitent anterior traction of the disc.
