This study was undertaken to evaluate new technique, which claims to reduce treatment time while retaining the quality of treatment. The aim of this study was to compare complete dentures made by two techniques: with the use of face bow and without the use of face bow.
Twenty edentulous subjects were selected and each one received two pairs of complete dentures. Dentures were made from duplicated casts and each one followed different techniques. One technique used face-bow. Teeth were set using individualized wax rims as guides. In other technique an articulator was used, which avoids face-bow and teeth were set by the cast-analysis method. The number of occlusal contacts in centric relation and excursive movements were registered, in addition to this the opinion of patients regarding denture bearing during oral functions were taken.
Both groups had dentures with balanced occlusion, but the technique that avoids face-bow presented better results in regard to time taken, esthetics, comfort and stability. Balanced occlusion was provided even without face-bow and could be an alternative to obtain adequate complete dentures with a better prognosis.
For achieving better quality of denture in the form of esthetics, phonetics and function in short duration of time; a new technique was used to establish balanced occlusion in complete denture prostheses.
本研究旨在评估一种声称能在保持治疗质量的同时缩短治疗时间的新技术。本研究的目的是比较两种技术制作的全口义齿：使用面弓和不使用面弓。
选择20名无牙颌受试者，每人接受两副全口义齿。义齿由复制模型制作，每种技术采用不同的方法。一种技术使用面弓，以个性化蜡堤为导向排牙。另一种技术使用架，不使用面弓，通过模型分析方法排牙。记录正中关系和前伸运动时的咬合接触点数，此外，还收集了患者对义齿在口腔功能时承托情况的意见。
两组义齿均具有平衡咬合，但不使用面弓的技术在制作时间、美观、舒适度和稳定性方面表现更佳。即使不使用面弓也能实现平衡咬合，这可能是获得预后更好的合适全口义齿的一种替代方法。
为了在短时间内实现义齿在美观、语音和功能方面的更好质量，采用了一种新技术来建立全口义齿修复体的平衡咬合。
