Abstract
This study was carried out to evaluate the effectiveness “Disk Recapturing Bite Plane” for the treatment of anterior disk displacement without reduction (closed lock).
The conclusions are summerized as follows.
1. Eight subjects were selected for this study. They were diagnosed as anterior disk displacement without reduction by clinical physical examinations, radiographic examinations, and chewing movement analysis using Sirognathograph Analysing System.
2. All subjects were treated by “Disk Recapturing Bite Plane”. This bite plane was adjusted so that symptomatic side was unilaterally high (0.5-1.0mm) at premolar and molar legion.
3. After treatment, evaluations were done as follows.
1) All signs and symptoms were disappeared.
2) Rapid recovery of mouth opening degree and appearance of clicking were observed.
3) The condyles of the patients with condylar retrodeviation were located centrally in the mandibular fossa after the treatment.
4) Bone changes of the TMJ components were disappeared.
5) Characteristic chewing patterns of closed lock were disappeared.
4. As mentioned above, it was suggested “Disk Recapturing Bite Plane” could successfully recapture the disk of the patients with closed lock.
