The Clinical Effect Of Occlusal Adjustment In The Treatment Of Temporomandibular Disorders Evaluated With T-Scan Ⅱ System

Objective:To investigate the effects of occlusal adjustment in the treatment of temporomandibular disorders(TMD) by using the T-Scan II system.Methods: 10 cases were chosen from the patients whose chief complaint was maxillofacial region muscle pain and temporomandibular joint (TMJ) clicking in our hospital, according to the indication of occlusal adjustment.All the cases were measured and analysised by the T-Scan II system prior and post the occlusal adjustment.Through the clinical examination and the value of visual analogue scale (VAS) to evaluate the clinical effect of occlusal adjustment by using the T-Scan II system.Results:1.After three months of the occlusal adjustment,all the 10 patients' clinical examination symptom were reduced or disappeared.2.Compared to pre-treatment,the value of all the TMD patients' VAS decreased obviously, and had statistical meaning.3. All the patients' COF tend to the center,and got the bilateral simultaneous occlusal contacts.4.The DT had significant reduced ,that is all posterior teeth disclude near instantaneously once a mandibular excursion is commenced(within 0.5s).Conclusions:1 .After the occlusal adjustment by T-Scan II system,the bilateral simultaneous occlusal contacts and all posterior teeth disclude near instantaneously once a mandibular excursion is commenced.So the disharmony relation of occlusion , muscle and the joint were relived.Thereby,the clinical complaint were improved.2.The occlusion disorder is a very important etiological factor of TMD.3.The date and the picture the T-Scan II system reflect were objective, exact and precise.It's an effective way to use this system to treat the TMD patients.
