Clinical evaluation of digital repositioning splint in the treatment of temporomandibular anterior disc displace-ment with reduction
Objective To analyze the clinical effect of digital anterior repositioning splints on anterior disc displace-ment with reduction.Methods Totally 40 patients diagnosed with anterior disc displacement with reduction were in-cluded and randomly divided into 2 groups(digital group and traditional group,n=20).The patients in digital group were treated by digital anterior repositioning splints while those in traditional group were treated by traditional anterior re-positioning splints mounted by self-curing resin.Time consuming of try-in,the patient-experience index,visual ana-logue scale(VAS)score and Fricton's craniomandibular index were compared between the two groups.Results Time consuming of try-in of the digital group was(379.8±91.0)s,obviously less than that of the traditional group[(816.9± 102.0)s]with statistically significance.Lower patient-experience index indicated better patient satisfaction:the digital group obtained lower scores than traditional group in three aspects(the try-in experience,influence on appearance and the odour of the splints)with statistical significance(P＜0.05).There were no statistically significant differences in the VAS scores or Fricton's craniomandibular index scores between the two groups(P＞0.05).The VAS of the digital and traditional group was(1.71±0.56)and(1.80±0.40)at 6 months after the treatment,obviously decreased when com-pared with that before treatment[(2.97±0.83),(2.94±0.79)],there being statistical significance(P＜0.05).The Fric-ton's craniomandibular index of both groups were significantly decreased after 6-month treatment(P＜0.05).Conclu-sion Digital anterior repositioning splints can achieve similar clinical effects when compared with the traditional anterior repositioning splints in the treatment of anterior disc displacement with reduction,with higher clinical efficiency and better patient experience.
