“…In the studies reported by Haradaet al, Iwase et al andBraber et al 9,10,12 , the authors assessed bite force, occlusion areas and chewing performance in prognathous and retrognathic patients, before and after orthognathic surgery, as well as in individuals with normal occlusion.Both studies verified that at the end of the follow-up period (that varied concluded that there was no statistically significant correlation of linear growth or decrease between the variables bite force and BMI.These findings are in agreement with those described in the study byBraun et al 3 , who conducted an investigation with the purpose of assessing the maximum human bite force and correlate it to several variables, among which are weight and height.The sample was composed of 142 individuals of both genders in between 26 and 41 years of age, and, in order to conduct the measurements, a transducer that measured the force in Newtons (N) was used. The correlation coefficients for weight and height were low.…”

“…Thus, the relationships between bite force and the type of dental occlusion have been studied for some time, without a present consensus in literature.Many studies justify that muscles, as well as teeth play an important role in the direction of the course of bite force and that muscle anatomy may both cause and reflect mandible movements and, thus the relative importance of the components of bite force may be associated to the different muscle anatomy of each one 4 .In addition, maximum bite force increases with the number of teeth that are present and the association between maximum bite force and the amount of occlusal contacts is more relevant in the posterior region and, as a consequence, the loss of molars, for instance, would result in a reduction of bite force 7 .There are studies that have found statistically significant differences between force measurements and the different types of occlusion, measured directly -using a force transducer -, with the smallest force having been found in individuals with malocclusion 7,8 .Studies conducted with prognathous patients before and after orthognathic surgery, measuring force in this same way, have shown that the parameters of bite force improve after surgery, although none reached the values of individuals with normal occlusion [9][10][11][12][13] .…”

OBJETIVO:analisar a máxima força de mordida na oclusão normal e maloclusões de Angle; observar a frequência de ocorrência dos tipos de oclusões; analisar a existência de diferença entre as medidas desta força e relacionar a força de mordida com índice de massa corpórea (IMC) de cada indivíduo.MÉTODOS: a amostra foi composta por 100 estudantes do curso de Fonoaudiologia, com faixas etárias entre 17 e 25 anos. Cada indivíduo realizou: 1) Anamnese: composta por dados de identificação pessoal, informações sobre alimentação diária; preferência mastigatória; peso e altura. 2) Classificação da oclusão dentária em: normal ou Classe I, II subdivisão 1ª e 2ª ou Classe III. 3) Avaliação da força de mordida por meio de um dinamômetro digital. Os resultados foram submetidos aos testes estatísticos: Kolmogorov-Smirnov, T-Student Pareado, Teste de Igualdade de Duas Proporções, Teste ANOVA, Comparação Múltipla de Tukey e Teste de Spearman.RESULTADOS:as maiores forças de mordida foram obtidas nos indivíduos com oclusão normal, seguida das maloclusões Classes I, II subdivisão 1ª e 2ª e III, respectivamente; houve maior frequência de ocorrência da maloclusão Classe I, seguida da oclusão normal, maloclusão Classes II subdivisão 1ª e 2ª e III; houve aumento da força média entre a primeira e terceira medida em ambos os lados; não houve correlação entre força de mordida e o índice de massa corpórea (IMC).CONCLUSÃO: o tipo de oclusão influenciou na força de mordida, sendo a maior força obtida após a terceira mensuração e não houve relação entre IMC e força de mordida.

“…With this dental prescale system, the distribution and magnitude of the occlusal force over the entire dentition can be measured close to that of natural occlusion. 23 The subjects were seated with the head in the natural position. The films were immediately read with a scanning apparatus (Dental Occlusion Pressuregraph 703; Fuji), and the maximum occlusal force was evaluated.…”

Objective: To clarify the relationship between occlusal force and mandibular condyle morphology using clinical data. Materials and Methods: The subjects were 40 female patients with malocclusion. The mandibular condyle morphology was assessed by using limited cone-beam CT imaging. The maximum occlusal force was calculated by using pressure-sensitive films. Maxillofacial morphologies were analyzed by using data from lateral cephalograms. Results: Correlation analysis showed that the occlusal force was correlated with the lateral and posterior radii of the condyles, and with the mandibular plane angle to the Frankfort horizontal plane (FH). Moreover, condylar length was significantly correlated with the occlusal plane angle to the FH, the mandibular plane angle to the FH, the ramus inclination, and the posterior facial height (S-Go). Low-occlusal-force patients tended to have smaller mandibular condyles. This sizerelated difference was more remarkable on the lateral and posterior side. Conclusions: Occlusal force influences not only maxillofacial morphology but also mandibular condyle morphology.

“…This system is now being used in various fields of dental research, particularly by Japanese researchers [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][22][23][24][25][26][27][28][29][30][31][32][33] . These studies have suggested that this system might help evaluating masticatory function and could be applicable to general dental clinical work.…”

We examined the feasibility of applying the Dental Prescale Occluzer System ™ to the evaluation of occlusion in orthodontic patients. The patients were classified according to the type of malocclusion or facial pattern. The values of occlusal contact area and occlusal force obtained from these individuals differed depending on the type of occlusion or facial pattern. These values were higher in individuals with normal occlusion than in patients with malocclusion and higher in patients with the Brachyo facial pattern than in those with the Dolico facial pattern. Because this system can very easily analyze the occlusal contact area, the mean pressure on each occlusal contact point, and the occlusal force during the process of orthodontic treatments, it can be useful as an aid for the initial diagnosis of occlusal problems, the observation of the changes in occlusion during treatment, and the establishment of the final goal of orthodontic treatments.
