RESUMO

The influence of occlusion contacts on the temporomandibular articulation dynamics and the tonus of mastication muscles have been stated in many researches. The harmony among these components of the mastication system will only be obtained, if the contacts that occur on the occlusion surface of the teeth, either during the end of closing or during mandible excursions, are identified in a precise method. Today there are many materials and techniques that were developed to attend this necessity. However, up to this date it is still a complex and time demanding job. The present research objectified to evaluate the occlusion contacts obtained at the end of mandibular closing, with the help of carbon paper straps and the association of a T-Scan computerized sensor system and carbon paper straps. Twenty-three individuals possessing Angle?s Class I, complete natural dentition, with no prior dental losses (except for third molars) and presenting occlusive contacts between the posterior teeth of the dental arcs were selected. The occlusion contact registers were obtained with the mandible positioned in maximum intercuspation. The data obtained were visually and statistically analyzed using the Biostart 3.0 software (Wilcoxon and Mcnemar tests). The visual analysis results revealed that the number of occlusion contacts registered in the mouth, much as carbon paper straps as sensor associate et carbon paper straps, were equal in all subjects. Also, the location of each contact point registered on the occlusion surfaces, for both techniques, was the same for each individual of the sample. When the number of occlusion contacts registered in the mouth, much as carbon paper straps as sensor associate et carbon paper straps, were to pair it the Wicoxon test, was verified that there were no differences among techniques (p=1). When the locations of the occlusion contacts registered in the mouth, much as carbon paper straps as sensor associate et carbon paper straps, were analyzed by the Mcnemar test, no differences were also observed between techniques (p=1). The technique that associates a sensor (T-Scan II) to carbon paper straps permitted the registration of location, number, distribution, sequence, time and relative intensity of occlusion contacts in a precise method
