Changes of upper airway morphology and dentofacial soft and hard tissue in patients with anterior disc displacement of temporomandibular joint af-ter anterior repositioning splint treatment
摘要
Abstract
Aim:To investigate the changes of upper airway morphology and dentofacial soft and hard tissue in patients with anterior disc displacement of temporomandibular joint after anterior repositioning splint treatment.Methods:Totally 22 patients with anterior disc displacement of temporomandibular joint caused by mandibular recession were included.Cone-Beam CT(CBCT)and lateral cephalogram were taken before and after splint treatment,and the related indexes of upper air-way,dentofacial soft and hard tissue were measured,and the differences before and after treatment were analyzed.Results:After treatment,94.7%of the patients'bouncing symptoms were relieved or disappeared,84.6%of the patients'pain was relieved or eliminated,and 85.7%of the patients'limited mouth opening were improved or normal.The complete reduction rates of the disc-condylar relationship of the reversible and irreducible sides were 76.7%and 8.3%,respectively.SNB,SN-MP,ANS-Me,S-GO,facial process angle,mental lip angle,Sn-Mes increased significantly(P<0.05).ANB,Wits,S-CO,U1-L1 angle,overbite,overjet and upper lip protrusion decreased significantly(P<0.05).Velopharyngeal airway volume,glossopharyngeal airway volume and minimum velopharyngeal cross-sectional area increased(P<0.05).Conclusion:Ante-rior repositioning splint is effective in the treatment of anterior disc displacement of temporomandibular joint caused by man-dibular recession.By guiding the anterior and inferior displacement of the mandible,the bony characteristics and facial shape of mandibular recession can be improved,the stenosis of velopharyngeal section can be improved,the volume of upper airway can be increased,and the symptoms of snoring can be relieved.关键词
