“…Based on the relationship between the condyle and articular fossa, some investigators reported posterior displacement of the mandibular position. [11][12][13] Hence, assessing the GS patterns is extremely interesting, and a significant evaluation regarding the relevance of occlusion/articulation and TMDs may be possible by using this method.…”

“…Further, posterior displacement of the mandible, determined on the basis of the relationship between the condyle and articular fossa, is dangerous and leads to TMJ dysfunction. [11][12][13] It is usually difficult to measure the loading and displacement of the condyle caused by the occlusal force associated with a parafunction such as bruxism. The quality of occlusion may be assessed by analyzing the pattern of condylar behaviors in relation to the articular fossa during lateral-border movement in the absence of tooth contact and in cases of bruxism in which there is strong contact between the upper and lower teeth; this is the first report regarding condylar dynamics.…”

We assessed the feasibility of a new classification method of condylar movements by determining condylar dynamics. This classification will help in understanding the influence of occlusion on condylar movement and may be used to diagnose the quality of functional occlusion. AbstractPurpose: The purpose of this study was to classify condylar dynamics to understand stomatognathic disorders and design effective treatments for functional occlusal disorders by considering comprehensive mandibular function. This assessment of categorizing of condylar movement in combination with frequency analyses will contribute to the diagnosis and treatment of functional occlusal disorders. Methods:Lateral-border movements with/without tooth contact were recorded from a reference condylar position in 102 patients (30 males and 72 females; mean age, 41.5±15.9 years) by using the CADIAX ® III (GAMMA, Klosterneuburg, Austria). After superimposing the two types of movement on both sagittal and horizontal planes, a trace of lateral movement with tooth contact was compared in terms of direction with the trace of the lateral movement without tooth contact. The area in the sagittal view was then classified into the following four categories: no-shift, upward shift, downward shift, and rearward shift. We obtained 10 grinding shift (GS) patterns by combining the four area categories of each condylar movement. Results:The data set of condylar movements-a total of 204 sides of the 102 patients-permitted us to classify the pattern of each subject into 1 of the 10 GS patterns. Conclusion:Since the GS patterns provided an active image of mandibular behavior during grinding movement, this newly developed classification is expected to improve the diagnosis of stomatognathic disorders.

“…Combining the previous research results, it can be estimated that approximately 35-45% of the population will develop Class II malocclusion in the permanent dentition. Much research has shown that the retrognathic mandible rather than the prognathic maxilla is the defining feature of Class II malocclusion [11,16] and this group of malocclusions often leads to craniomandibular disorders [12,25]. Class II malocclusion presents a substantial risk to oral health, and we therefore urge dental professionals to recognize the condition in the earliest stage possible in order to implement early therapeutic interventions.…”

Purpose: In order to examine the relationship between the vertical dimension change and the growth of the maxillo-facial complex in the mixed dentition, we applied a denture frame analysis including the measures of vertical dental and skeletal height, and maxillo-mandibular growth.Materials and methods: The materials used in this study consisted of 225 pair of dental casts in occlusion and serial lateral cephalograms of 25 children. We observed their occlusion and growth in the initial stage (Stage 1), beginning of exchange of the buccal segment (Stage 2), end of exchange of the buccal segment (Stage 3), and final stage (completion of occlusion, Stage 4).Results: Most of the dentition (58%) became Class I molar relation before Stage 2 and almost all of the Class II at Stage 2 remained as Class II occlusion at the final occlusion (Stage 4), indicating rarely available Lee way space for obtaining Class I molar relation. The skeletal Class II group showed a significantly higher eruption of the lower first molar in Stages 2 and 3, while Class III skeletal group showed a significantly higher eruption of upper first molars at Stage 4. There were significant differences of posterior occlusal plane (POP) in different skeletal frames.Conclusion: The results suggested that the increase in vertical dimension and inclination of the POP influence the growth of the mandible in obtaining Class I molar relation and that improper vertical dimension and inclination of POP are related to the development of skeletal malocclusions.

“…Vários trabalhos identificaram a falta de concentricidade do côndilo em relação à fossa articular como característica própria de indivíduos sintomáticos. A posição mais posterior do côndilo foi considerada fator predisponente a desarranjos articulares (ARTUN;TRUELOVE, 1992;MIKHAIL;ROSEN, 1979;PULLINGER et al,1986;WEINBERG, 1983). Porém, Pullinger et al (1985) verificaram que não se poderia indicar tratamento da posição condilar nãoconcêntrica por esta apresentar-se também em população assintomática.…”
