Physiotherapeutic methods of treatment of mandibular distal occlusion and the progress of therapy: A case report

BackgroundStudies have demonstrated a relationship between dental malocclusion and posture defects. The aims of the study were to present (1) the effect of a physiotherapeutic approach to a patient with a distal occlusion defect with the use of a set of exercises to strengthen the muscles responsible for mandibular protrusion, and (2) a non-invasive and easy-to-use method to monitor the effects of therapy.MethodsFive year old girl with a distal occlusion and with a low basic postural tone was referred to physiotherapy. A therapeutic program i.a. concerning a strengthening of the temporomandibular joint muscles with the use of a flexible tape was proposed. To assess the functional changes of the masticatory apparatus a photoanthropometric method was used. In side-face photos, proportions of 2 linear measurements and values of two angles on the first day of therapy, after 2 and after 4 months of exercises, with the mandible located freely and in the maximum protrusion were compared.ResultsA comparison of indices and angles showed a marked improvement in mandibular mobility already after two and four months of the exercises. Using the elastic resistance tape in addition to general developmental exercises allowed for increasing the mobility in the temporomandibular joint.ConclusionMalocclusion should not be considered separately, without taking into account the body posture. The work of the physiotherapist can benefit the orthodontist, correcting postural defects and consequently affecting malocclusion. A comparison of linear measurements and angles can be used to assess the progress of the therapy.

2种量表在评定青少年主观(牙合)美观程度中的应用

目的:采用视觉模拟量表(visualizedanaloguescale,VAS)和正畸治疗需要指数的美学量表(aestheticcompo鄄nent,AC)分别量化评定青少年的自身牙合美观程度,比较两者的评定效能及信度。应用SPSS11.0统计软件包进行相关分析。方法:随机抽取上海地区11～13岁青少年共302例(男148例,女154例),分别采用2种量表进行牙合美观程度的主观评价,同时由正畸医生进行牙合美观程度的客观评定。结果:Spearman相关检验显示,自评AC及VAS均与性别无关(P>0.05);VAS分值与主观牙合美观满意度显著相关(r=0.80,P=0.000),且与正畸医生的专业评定一致性较高;自评AC等级与主观牙合美观满意度无显著相关性(P=0.441)。结论:应用VAS量表评定青少年主观牙合美观程度的可信度较高且简单易用,适合定量分析,为今后量化评定主观正畸治疗需求提供了一种新方法。     

SEGMENTAL LEFORT I OSTEOTOMY FOR TREATMENT OF A CLASS III MALOCCLUSION WITH TEMPOROMANDIBULAR DISORDER

This article reports the case of a 19-year-old young man with Class III malocclusion and posterior crossbite with concerns about temporomandibular disorder (TMD), esthetics and functional problems. Surgical-orthodontic treatment was carried out by decompensation of the mandibular incisors and segmentation of the maxilla in 4 pieces, which allowed expansion and advancement. Remission of the signs and symptoms occurred after surgical-orthodontic intervention. The maxillary dental arch presented normal transverse dimension. Satisfactory static and functional occlusion and esthetic results were achieved and remained stable. Three years after the surgical-orthodontic treatment, no TMD sign or symptom was observed and the occlusal results had not changed. When vertical or horizontal movements of the maxilla in the presence of moderate maxillary constriction are necessary, segmental LeFort I osteotomy can be an important part of treatment planning.     

错矫治治疗颞下颌关节紊乱病临床疗效分析

目的 分析并评价矫治错(牙合)同时治疗颞下颌关节紊乱病(TMD)的临床效果。方法 采用直丝弓技术矫治各种错(牙合)畸形伴TMD患者42例,详细记录治疗前、治疗6个月、治疗结束、治疗结束后2年的牙(牙合)情况及TMD症状、体征变化、颞下颌关节(TMJ)X线片情况。结果 30例患者TMD症状及体征基本痊愈,占71.4％;好转7例,占16.7％;无效或加重5例,占11.9％。结论 错(牙合)畸形伴TMD的年轻患者经正畸矫治可以恢复咬合或作(牙合)重建,建立(牙合)平衡,使颞下颌关节、下颌回复到正常解剖位置。但已经发生器质性损害或TMJ解剖结构不对称的患者,治疗效果有待于进一步观察。     

骨性Ⅲ类错畸形对语音功能的影响

为了探讨骨性Ⅲ类错畸形对语音功能是否有影响，我们以２０名骨性Ⅲ类错畸形的成年患者为研究对象，由语音专家对其语音进行判听，同时应用计算机语音工作站（ｃｏｍｐｕｔｅｒｉｚｅｄｓｐｅｅｃｈｌａｂ）进行了语音声学分析。结果表明：①多数此类错患者存在语音功能异常，在ｚｈ、ｃｈ、ｓｈ、ｚ诸辅音上最常出现发音错误，错误类型为发音失真（ｄｉｓｔｏｒｔｉｏｎ）和发音替代（ｓｕｂｓｔｉｔｕｔｉｏｎ）。②语音声学分析显示，与正常辅音相比，有发音错误的辅音频率下限下移，频率分布范围变宽，低频成份增加。本项研究结果表明，骨性Ⅲ类错畸形能导致语音功能异常，在口腔正畸外科正畸联合矫治骨性畸形的同时，应考虑患者语音功能的改善。
