The purpose of this article is to investigate the effect of the restoration of single tooth by crown on chewing movement. Chewing movement was recorded and analyzed by Sirognathograph Analyzing System on 12 subjects both on restored side chewing and on contralateral side chewing, with the restoration and without the restoration.
The result showed there were no common evident difference among those experimental circumstances in all subjects. However, there were several parameters which might be affected among those circumstances in individuals. The parameters were the lateral deviation of closing path and the duration of occluding phase in the restored side chewing and the lateral deviation of closing path near intercuspal position and the duration of occluding phase in the contralateral side chewing.
