颞下颌关节紊乱病(TMD)是一种由关节结构、咬合、肌功能异常及精神心理等多种因素综合作用形成的口颌面部疾病。闭锁型深覆[牙合]、个别前牙与后牙反[牙合]、后牙锁[牙合]、一侧后牙反[牙合]、下颌偏斜、磨牙伸长、磨牙倾斜等是诱发TMD的高危险[牙合]因素。从整体分析,正畸治疗与TMD并无密切相关性,但部分病例TMD的发生仍可能与正畸治疗不当有关。良好的牙齿排列、正常的前牙覆[牙合]与覆盖关系及后牙尖窝对应关系、牙位与肌位一致、下颌前伸与侧[牙合]平衡是有效预防与缓解TMD的可靠保证。本文对错[牙合]畸形及正畸治疗与TMD的相关性研究文章进行系统回顾,结合正畸临床实际,分析错[牙合]畸形与TMD的内在联系,以及正畸治疗中TMD的风险和防治策略。 相似文献

Objective: The aim of the present study was to evaluate the prevalence of self-reported temporomandibular disorders (TMD) symptoms and clinically diagnosed TMD among Finnish prisoners. Material and methods: Altogether 100 prisoners from the Pelso Prison, Vaala, Finland, underwent dental and TMD clinical examinations performed by a calibrated and well-trained dentist. Symptom Questionnaire and clinical examination according to a Finnish pre-final version of the DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) Axis I protocol were used to evaluate the prevalence of TMD sub-diagnoses. Results: The most common TMD symptoms were facial pain (54.0%), temporomandibular joint noises (43.0%) and headache (37.0%). The prevalence of joint-related TMD diagnoses was four and a half times higher than diagnoses attributed with pain (76.0% vs. 17.0%). The most common TMD diagnoses were degenerative joint disease (33.0%) and disc displacement with reduction (33.0%). Conclusions: The prevalence of self-reported TMD symptoms and clinical assessed TMD, especially join-related TMD diagnoses, is high among Finnish prisoners. Examination and treatment of TMD should become a common practice also in prison dental care. 相似文献

Temporomandibular joint dislocation is defined as the loss of joint congruency between the mandibular condyle and the glenoid fossa of the temporal bone. Multiple therapeutic options have been proposed for the treatment of recurrent TMJ dislocation. The aim of this paper is to present two recently treated cases with a modification of Wolford's technique, replacing the Mitek anchors with orthodontic screws. Case series: The first case concerns a 36 year-old women with recurrent temporomandibular dislocation, and the second one a 26 year-old patient with the same diagnosis. In both cases, one 8mm orthodontic screw was placed in the lateral pole of mandibular condyle, sutured with PremiCron® 2/0 to a hole made in the root of each zygomatic arch. At twelve-month follow-up (first patient) and at six-month follow-up (second patient), patients had not presented new episodes of mandibular dislocation and mouth opening range remained stable.This technique can be considered as an alternative to Wolford's technique in treating recurrent temporomandibular dislocation when conservative management fails. 相似文献

The objective of this systematic review was (a) to establish the prevalence of temporomandibular disorders (TMDs) in patients seeking orthodontic treatment and (b) to determine the association between the presence of TMD and sex, age and malocclusion. A systematic literature search was performed according to PRISMA guidelines from 1969 to 2019 using the PubMed and LIVIVO databases. Eight study articles met the inclusion and exclusion criteria. An additional three contributions were identified through manual searching of the reference lists of retrieved articles. The methodological quality of the 11 articles was assessed with the Joanna Briggs Institute Critical Appraisal Checklist for prevalence studies. TMD prevalence ranged from 21.1% to 73.3%. The frequency of painful TMD signs/symptoms varied from 3.4% to 65.7%, while non-painful signs/symptoms ranged from 3.1% to 40.8%. The percentage of males and females presenting with TMD varied from 10.6% to 68.1% and 21.2 to 72.4%, respectively. In all studies, TMD prevalence was higher among females. The majority of articles reported more TMD signs/symptoms in individuals older than 18 years as compared to younger ones (≤18 years). While in four studies no association between TMD and malocclusion was found, another three investigations indicated that TMD may be related to certain occlusal traits. The TMD prevalence in patients seeking orthodontic treatment was high, with many individuals presenting painful TMD signs/symptoms. Female and older patients appear to have a greater occurrence of TMD. Although no strong association between TMD and malocclusion was established, several occlusal traits were implicated. 相似文献

Objective: The aims of this study were to assess the prevalence of temporomandibular disorders (TMD) among adolescents and to contrast the prevalence of TMD according to the DC/TMD clinical examination protocol versus the prevalence of pain related to TMD according to two screening questions. Material and methods: Two hundred and ten adolescents living in the county of Bergen, Norway, were offered an additional examination for TMD in connection with their regular dental check-up appointment. Five dental clinics were selected with differing socio-economic patient populations, as reflected by stratification of average levels of DMFT, and an equal number of girls and boys were invited to participate. The participants answered two screening questions for pain related to TMD followed by a clinical examination according to the DC/TMD protocol by five calibrated examiners. Results: Acceptable calibration results were obtained. Approximately 80% of eligible participants consented to partake. According to the criteria of DC/TMD, the prevalence of TMD among the study participants was 11.9%, with a peak at 16 years of age. According to the self-reported screening questions for pain related to TMD, 7.2% responded positively. Only seven participants with a TMD diagnosis established according to the DC/TMD clinical examination protocol reported also pain related to TMD based on answering the two screening questions. Conclusion: The prevalence of TMD is higher for girls than for boys and the prevalence of TMD established according to the DC/TMD criteria was higher than the prevalence of pain related to TMD estimated by use of two screening questions for self-reported pain. 相似文献

A temporomandibular disorder (TMD) screening history and screening examination was performed on 523 young adult males. The screening forms were similar to those TMD forms developed and formulated under the auspices of the American College of Prosthodontists. In turn, the substance of the latter forms was initially derived from the recommendations of the President's TMD Conference of the American Dental Association, with 62 eminent researchers, educators and clinicians as participants. Each subject was given a TMD self-administered screening history form to complete, formatted in a check - the block format. It included all items considered to be classic TMD symptoms. The screening examination was performed extraorally and included (i) range of jaw movement, (ii) digital palpation of selected masticatory muscles and palpation over the pre-auricular temporomandibula joint (TMJ) area and (iii) digital palpation for TMJ sounds during jaw movement. The subjects were categorized into the following four categories: 0 = no symptoms/signs, 1 = insignificant moderate symptoms and/or signs, 2 = significant moderate symptoms and/or signs, and 3 = severe symptoms and/or signs. The overall results showed that 75% of the subjects had TMD symptoms and/or signs. There were 6.9% in category 1, 51.4% in category 2, and 16.7% in category 3. It was recommended that subjects in category 2 and 3 should have a comprehensive TMD evaluation, in order to further identify the recommended need for TMD Therapy. 相似文献

Objective: The aim of this study was to identify clinical factors predisposing to the development or worsening of temporomandibular disorders (TMDs) following orthodontic surgical treatment for Class III malocclusion. Methods: A retrospective cohort study was performed on 88 patients with Class III malocclusion having undergone a combined orthodontic and orthognathic surgical treatment. Temporomandibular joint and masticatory muscle examinations were available prior to treatment and one year post-operatively. Multivariate logistic regression was used to predict the development of post-operative TMDs, and linear regression was used to predict the worsening of TMDs using Helkimo indices. Results: Patients with Class III malocclusion presenting with pre-treatment anamnestic TMJ clicking (OR = 5.8; p = 0.03) and undergoing bimaxillary osteotomy procedures (OR = 18.6; p = 0.04) were more at risk for the development of TMDs. Discussion: TMDs must be evaluated, monitored, and managed with caution in patients with Class III malocclusion presenting with pre-treatment joint clicking and who are planned for bimaxillary osteotomies. 相似文献
