“…The presence of TMD has been largely discussed in all stages of DFD treatment, and the literature shows that subjects present a high rate of TMD signs and symptoms in the pre-surgical orthodontic treatment phase as compared to post-surgical one [15][16][17][18][19][20][21][22] . Nevertheless, although some authors have verified a reduction in the occurrence of TMD in individuals, following the orthognathic surgery, they report no relationship between dentofacial deformities and TMD 23,24 .…”

Resumo:OBJETIVO:verificar a ocorrência de disfunção temporomandibular em indivíduos com deformidade dentofacial.MÉTODOS:foram avaliados 60 indivíduos de ambos os gêneros e idade entre 18 e 40 anos (média=27 anos), sendo formados dois grupos, um composto por 30 sujeitos com deformidade dentofacial, em tratamento ortodôntico pré-cirúrgico e um grupo controle constituído por 30 indivíduos com equilíbrio dentofacial, pareados segundo o gênero e a idade com o grupo deformidade. Para avaliação da articulação temporomandibular, foram aplicados o questionário anamnésico de disfunção temporomandibular e o Eixo 1 do Research Diagnostic Criteria for Temporomandibular Disorderspara verificar e classificar o grau e o tipo da disfunção temporomandibular, respectivamente.RESULTADOS:os resultados da aplicação do questionário demonstraram que o grupo com deformidade apresentou maior grau e escore da disfunção que o grupo controle (p<0,01). A partir do Research Diagnostic Criteria for Temporomandibular Disorders verificou-se maior ocorrência de diagnósticos de deslocamento de disco (p=0,02) e de artrite, artralgia e artrose (p<0,01) no grupo com deformidade em relação ao grupo controle.CONCLUSÃO:indivíduos com deformidade dentofacial apresentaram maior ocorrência de disfunção temporomandibular, quando comparados aos indivíduos com equilíbrio dentofacial, na amostra estudada.

SUMMARY:The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3%) CR was observed , with a 97.6% (122) female. CR was related to 118 cases with mandibular deficiencies with high mandibular plane (advancement surgery). CR were present principally in bi maxillary surgery with a 103 cases (75.2%) and only two papers show any analysis to the relation with TMJ dysfunction. Current evidence in CR is poor but supports those female patients with mandibular deficiency and high mandibular plane angle submitted to bi maxillary surgery with change in occlusal plane (counterclockwise) are associated with condylar resorption after orthognathic surgery.

“…Some studies demonstrated that the degree of dysfunction may be maintained, even after surgery (27,28) . This highlights the need of further studies relating the skeletal and functional disorders present in the presurgical stage, by assessment of the TMJ and masticatory function, to effectively assess the improvement in the postsurgical treatment.…”

Introduction: Individuals with dentofacial deformity (DFD) show impairment in dental occlusion, which may alter the masticatory performance and, consequently, the bite force. No research was found on the relationship between temporomandibular disorders (TMD) and bite force for this population. Purpose: To determine if the presence of TMD symptoms influence the maximum bite force (MBF) in individuals with DFD. Methods: Sixty individuals were evaluated, 30 with DFD (GDFD) and 30 with normal occlusion (CG). The TMD was assessed by an anamnesis questionnaire (AQ) containing 10 questions that allow classification of the presence and degree of signs and symptoms of TMD. MBF was assessed using a mandibular force sensor, of the EMG System 810c electromyograph. Three records of bite force were obtained, with 10-second duration each. The Spearman correlation coefficient was used, at a significance level of 5%. Results: The results of AQ showed higher prevalence of TMD symptoms in GDFD in relation to CG. Also, lower MBF was observed in subjects with DFD compared to CG. In addition, negative and significant correlations were found between scores obtained in the application of AQ and the MBF; therefore, the higher the severity of TMD symptoms, the lower the bite force. Conclusion: The presence and severity of TMD symptoms influenced the MBF in individuals with DFD, demonstrating the importance for interdisciplinary intervention during all stages of surgical-orthodontic treatment.
