Abstract:
Objective To evaluate the adaption of the condyle position of patients with extensive tooth wear during occlusal rehabilitation,and the correlation between increased vertical dimensions and the changes of joint spaces.Methods Twenty-seven patients(five from Beifang hospital,others from Peking University School and HospitM of Stomatology)with extensive tooth wear were selected and received occlusal 1),1 month following delivery of temporary restoration(stage 2),and 1 month following delivery of permanent restoration(stage 3).Results The superior,anterior and posterior joint spaces were(3.24±0.16),(2.06±0.11),(1.89±0.13)mm at stage 1;(3.61±0.15),(1.94±0.10),(2.52±0.11)mm at stage 2;(3.49±0.19),(1.93±0.10),(2.40±0.13)mm at stage 3.The posterior joint spaces at stage 2 and stage 3 were significantly larger than that at stage 1(P<0.01).The superior spaces at stage 2 were significantly larger than that at stage 1(P<0.05).No correlations between the increased vertical dimensions and the changes of joint spaces were found in the three stages(P>0.05).Conclusions The condyle positions in the patients with extensive tooth wear changed after occlusal rehabilitation.
