“…In the presence of an increased mandibular plane angle, the lower incisors tended to show more pronounced lingual inclination, which is consistent with results reported by Beckmann et al, 11 Bjö rk, 15 Bjö rk and Skieller, 16 and Frost et al 19 Although NCOBG did not differ significantly from CG, significantly retroclined upper incisors were noted in COBG. This finding corresponds to results reported by Beckmann et al 11 and Kuitert et al 26 Proclination of incisors during poorly managed biomechanics can result in iatrogenic bite opening in compensated open bite patients. Outcomes related to incisor compensation in skeletal open bite subjects were corroborated by analysis of the three groups according to sagittal skeletal relationships.…”

“…When we evaluated incisor height along the long axis of the alveolar process, where the results are not biased by the inclination of incisors, dentoalveolar height of the mandibular incisors (MDIABHb) provided the greatest contribution to the dental compensatory process, as published previously by other authors. 11,25,26 Therefore, vertical dentoalveolar compensation in skeletal open bite adult patients appears to be caused by significant elongation of both upper and lower incisors, with lower incisors playing a more important role. This confirms that excessive extrusion of incisors in open bite treatment may bring results that are neither stable nor esthetic.…”

“…The choice of treatment protocol depends on many factors, including esthetic and occlusal aspects, morphologic characteristics, and the severity of the skeletal anomaly. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] The indication for molar intrusion is often based on the assumption that the value of molar height in open bite patients is greater than in the ''normal population.'' 2,6,10,[27][28][29] Many authors state that increased molar height is one of the common features of individuals with dentoskeletal open bite, and they advocate molar intrusion to correct the disharmony.…”

Objective: To evaluate the skeletal and dentoalveolar components in adult subjects with skeletal open bite in the presence or absence of dental compensation. Materials and Methods: The study sample included 69 adult female subjects who belonged to three groups according to skeletal vertical relationships and overbite. A total of 15 variables (5 angular, 10 linear) were evaluated. Values in the dentally compensated open bite group (COBG), the dentally noncompensated open bite group (NCOBG), and the control group with normal vertical skeletal relationships and overbite (CG) were compared by means of parametric statistics. Results: The COBG and the NCOBG showed significantly greater incisor and molar heights in both jaws than the CG. No significant difference in upper or lower molar height was found between COBG and NCOBG. Incisor height was significantly greater in COBG than in NCOBG. Elongation in the incisor region was accompanied by significant narrowing of the lower anterior alveolar process in both skeletal open bite groups. Proclination of the upper incisors was significantly smaller in the COBG than in the other groups. Conclusions: Dentoalveolar components consisting of incisor elongation and inclination play a significant role in compensating for skeletal open bite configuration in adult subjects. Increased molar height is a common finding in adults with skeletal open bite. (Angle Orthod. 2011;81:564-569.)

“…16,17,18 The type II anti-clockwise mandibular rotation presents its center at the incisor contact area, 9 and is not normally related to overbite. However, if occlusion of the incisors is unstable, the fulcrum point will be located more posteriorly, and the bite will deepen with time.…”

“…Normal overbite in individuals with an elongated face may be maintained by limited inferior dentoalveolar compensation. 17 Some factors may influence the occurrence of compensatory mechanisms. Compensation requires that the eruptive system be normal and that the forces exercised by soft tissue be in balance.…”

Association between overbite and craniofacial growth pattern

The purpose of the present study was to assess the association between overbite and craniofacial growth pattern. The sample comprised eighty-six cephalograms obtained during the orthodontic pretreatment phase and analyzed using the Radiocef program to identify the craniofacial landmarks and perform orthodontic measurements. The variables utilized were overbite, the Jarabak percentage and the Vert index, as well as classifications resulting from the interpretation of these measurements. In all the statistical tests, a significance level of 5% was considered. Measurement reliability was checked by calculating method error. Weighted Kappa analysis showed that agreement between the facial types defined by the Vert index and the direction of growth trend established by the Jarabak percentage was not satisfactory. Owing to this lack of equivalency, a potential association between overbite and craniofacial growth pattern was evaluated using the chi-square test, considering the two methods separately. No relationship of dependence between overbite and craniofacial growth pattern was revealed by the results obtained. Therefore, it can be concluded that the classification of facial growth pattern will not be the same when considering the Jarabak and the Ricketts analyses, and that increased overbite cannot be associated with a braquifacial growth pattern, nor can openbite be associated with a dolichofacial growth pattern.
