RESUMO

This study aimed to observe the graphs of mandibular movements and the usual closing point of mandible, without external influence, before and during the use of Nóbilo s Complete Denture with Sliding Plates, through intraoral graphic registers. Twelve completed toothless patients, alleast for 10 years, and in the age between 50 and 80 years old, were selected. The Nóbilo s Complete Dentures with Sliding Plates were made based on face s Vertical Dimension, equable to facial golden proportions. The rates of bipupilar-Iabial comissure and nose bases-chin were equivalent to those which the patients showed before the installation of the disfunction, evidenced by analyses of photographs taken in the time when the patients had their natural teeth. Theses Dentures presented plane and smooth occlusal plataforms, which permitted mandible movement with more liberty. Proposed Dentures were evaluated during 120 days, adjusted weekly in the first month, and fortnightly until the end of 120 days. Allregisters of maxillomandibular relations of the patients were obtained through the plataforms of the intraoral registers according to Nóbilo s technic. Although, to make easy the graphics registers ofhorizontal movements, we idealise interchangeable metallic plates that were used during the times: O (zero), 15,45,75 and 120 days, in 10 patients. We obtained registers of 8 of these patients after 365 days of use of Nóbilo s Complete Denture with Sliding Plates. With 120 days of use of the proposed Complete Dentures, we observed that in 70% of patients, there was harmony in their trace of the gothic arch, and 90% of patients brought near of the usual closing point of Centric Relation. The vertex of the gothic arch was considered as the position of Centric Relation
