“…Also, Kucera et al 12 found that in the skeletal open bite group, the incisor height was significantly elongated compared with CG by approximately 3 mm. Our results were consistent with those of previous studies, [12][13][14][15][16][17][18][19] but they contradict those reported by Nahoum,20 who found smaller values for incisor height in patients with open bite with respect to CG. None of these studies took into account the sagittal skeletal pattern.…”

“…Intrusion of the posterior teeth as the treatment of choice has been indicated by some studies, 12,13 although the long-term stability of molar intrusion is still controversial. According to Baek et al, 18 relapse occurred on an average of 23% of the amount of molar intrusion facilitated by microscrews within 3 years of the postretention period.…”

Objective: To compare the anterior dentoalveolar and skeletal maxillary cephalometric factors involved in excessive upper incisor crown exposure (UICE) in subjects with skeletal open bite Class II (SOBCIIG) and Class III (SOBCIIIG) against an untreated control group (CG). Materials and Methods: Seventy pretreatment lateral cephalograms of orthodontic young adult patients (34 men, 36 women) were examined. The sample was divided into three groups according to both sagittal and vertical growth pattern and occlusion. The CG group (n 5 25) included Class I, normodivergent cases with adequate overbite, and the SOBCIIG group (n 5 25) and SOBCIIIG group (n 5 20) included skeletal Class II or III malocclusions, respectively, with hyperdivergent pattern and negative overbite. Several cephalometric measurements were considered (skeletal and dental). Analysis of variance, multivariate analysis of covariance, and Tukey HSD post hoc tests were used. Principal component analysis (PCA) was used for reducing the number of cephalometric variables related to UICE. Finally, a multiple linear regression was calculated. Results: Significant differences in UICE were found between the groups (P , .05). UICE was 3.9 mm in SOBCIIG, 2.5 mm in SOBCIIIG, and 0.4 mm in CG. PCA showed that a nondental component-including vertical maxillary height (VMH) and upper lip height (ULH)-was the only component significantly associated with UICE. The regression model had a moderate prediction capability. Conclusions: Although the UICE was statistically different in SOBCIIG, the values were within the esthetic standards. The UICE was mainly influenced by VMH and ULH. (Angle Orthod. 2015;85:72-79.)

“…Maxillary molar intrusion showed a 0.1-mm relapse and the mandibular plane a 0.178 relapse, in agreement with Deguchi et al 6 and Baek et al 10 Some of the methods used for AOB correction described in the literature are either invasive (miniplates, miniscrews, extractions) or require patient collaboration (removable bite-blocks). The therapy …”

“…[12][13][14][15]18 It is not possible to assess the real success of AOB treatment unless long-term stability is evaluated, as relapse often occurs during the first years of retention. 4,6,10 In the present study, measurements were taken before and immediately after treatment, and also some years after treatment (after an average of 32.9 months and never less than 12 months).…”

“…8 Some studies with long-term follow-up periods indicate that both surgical and nonsurgical treatments close the AOB effectively, but are prone to some relapse 9 in the first years of retention. 4,6,10 Orthodontists usually obtain bite closure by combining incisor extrusion or uprighting and molar intrusion, ideally obtaining a counterclockwise rotation of the mandibular and occlusal planes.…”

Objective: To (1) evaluate the efficacy of build-ups in the correction of anterior open bite in adults, (2) evaluate their efficacy in producing molar intrusion, (3) analyze skeletal and dental changes, and (4) assess the long-term stability. Materials and Methods: The sample consisted of 93 lateral cephalograms from 31 patients with skeletal and dental anterior open bite. The patients had received orthodontic treatment consisting of bonded resin blocks on the maxillary molars combined with Tip-Edge Plus bracket appliances. Cephalometric measurements were performed on radiographs taken before treatment (T1), after treatment (T2), and after a retention period (T3), which were analyzed and compared. Results: Significant dental and skeletal changes were observed after treatment. Molar intrusion averaging 1 mm; 1.44 and 1.57 mm extrusion of mandibular and maxillary incisors, respectively; and a mean of 3.98 mm overbite increase were observed. The mandibular plane angle showed a mean closure of 1.198, and there was a mean decrease in anterior facial height of 0.7 mm. A mild relapse tendency was observed, but long-term stability was acceptable. Conclusions: Build-ups are an effective treatment alternative for anterior open bite in adults. Outcomes remain significantly stable during the retention period. (Angle Orthod. 2017;87:33-40)
