Development of Harmonious Occlusion For Complete Denture Patient Using Functionally Generated Path Technique - A Case Report.

The edentulous state represents a compromise in the integrity of the masticatory system . The common treatment option for rehabilitation of edentulous state is the conventional complete denture. Occlusal paths and Cuspal paths generated on the mechanical articulator often differ from those that are actually generated in the mouth . Functionally generated path technique is one such approach which aids in the automatic determination of the geometric harmonious relation between the functional occlusal path and condylar paths at chosen vertical dimension . This technique permits the registration of the cusp movements as determined by the functional mandibular movements and thus helps in development of harmonious occlusion. This article describes a case report in which a step by step approach was used to develop functionally generated occlusal path in fabricating a complete denture.

Differences in opening and protrusive mandibular movements between Class I and II malocclusions in healthy adolescents / 대한치과교정학회지

OBJECTIVE: The aim of the study was to compare the opening and protrusive mandibular movements between Class I and Class II malocclusions in healthy adolescents by clinical and axiographic evaluations. METHODS: Mechanical axiography was performed on non-orthodontically treated, temporomandibular disorder (TMD)-free adolescents (12 - 16 years) with Class I (n = 38, 16 boys, 22 girls) or Class II (n = 40, 19 boys, 21 girls) malocclusion. Opening and protrusive movements were measured clinically and axiographically. Intergroup comparisons were evaluated by t-tests. RESULTS: In opening movement, the maximum clinical opening capacity was significantly different (p < or = 0.05) between the groups. In protrusive movement, the Class II group had significantly greater maximum clinical protrusion (p < 0.001) and maximum axiographic protrusive length (p < 0.01) than the Class I group. No significant difference in the other opening and protrusive axiographic measurements was observed. CONCLUSIONS: TMD-free adolescents with Class II malocclusion have increased protrusive capacity compared with TMD-free adolescents with Class I malocclusion; however, the detected differences could be normal variations during adolescence.
