Abstract

Management of the patient with worn dentition has been required the reestablishment of occlusal vertical dimension and comprehensive treatment planning for each case. In the present study, the effect of increased occlusal vertical dimension with dental restoration on the EMG activities and functional indices of masticatory muscles have been evaluated. The rehabilitation of three patients with worn dentition was presented. Before and after the restorative treatment, EMG recordings were taken and the activity index and asymmetry index were measured. The functional indices have been found more related to occlusal contact stability.

Keywords

Diş aşınması olan hastalarda dikey boyutun yeniden yapılandırılması sonrasında çiğneme kaslarının EMG aktivitesinin değerlendirilmesi: Vaka Serisi

Abstract

Aşınmış diş yapısına sahip hastanın tedavisi, oklüzal dikey boyutun yeniden oluşturulmasını ve her bir vaka için kapsamlı tedavi planlamasını gerektirir. Bu çalışmada diş restorasyonu ile artan oklüzal dikey boyutun çiğneme kaslarının EMG aktiviteleri ve fonksiyonel indeksleri üzerindeki etkisi değerlendirildi. Dişlerinde aşınma olan üç hastanın rehabilitasyonu sunuldu. Restoratif tedavi öncesi ve sonrasında EMG kayıtları alınarak aktivite indeksi ve asimetri indeksi ölçüldü. Fonksiyonel indekslerin oklüzal temas stabilitesi ile daha fazla ilişkili olduğu bulunmuştur.
