“…In the present systematic review, the mean AOB before treatment ranged from -0.63 mm to −4.75 mm. Marzouk et al (20) noticed the initial AOB of −4.75 mm. The mean amount of correction at T2 varied from 0.2 mm to 2.6 mm, with highest (2.6 mm) correction noticed by Silva et al (15).…”

“…In the present review, eight studies (8,10,(12)(13)(14)16,17,20) used mixed malocclusion (Class I, Class II, and Class III). Out of eight studies, five studies did not find any significant difference in malocclusion type and long-term stability of corrected AOB (8,10,14,17,20), and two studies showed significant relapse in Class II cases compared to Class III (12,16). The study by Tietten et al (13) showed Class II cases with low facial heights have less relapse compared to Class III subjects with high mandibular plane angles.…”

“…In the present systematic review, eight studies used the non-extraction method to correct AOB (8,(12)(13)(14)(15)(16)18,19), five studies used extraction and non-extraction patients (7,9,10,17,24), and one study used only extraction cases (20). Out of five studies that compared extraction and non-extraction methods to treat open-bite malocclusion, four studies (7,9,17,24) did not find any statistically significant difference between extraction and non-extraction methods in long-term stability of treated open-bite, whereas the study by Janson et al (10) showed that the subjects with extraction presented with a high level of stability (74.2%) compared to non-extraction cases (61.9%).…”

“…They include severity of AOB malocclusion prior to treatment, extractions of premolars, correction of open-bite with or without orthognathic surgery, or different methods of retention (4,5). Recently, many studies have been conducted to check the long-term stability of corrected AOB malocclusion (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). When we searched the literature, we came across two systematic reviews of case series studies conducted to assess the effectiveness of orthodontic and orthopedic treatment in AOB correction (4,5).…”

Objective: The present systemic review was conducted with the main purpose to evaluate the quantitative effects of orthognathic surgeries, extraction versus non-extraction treatment, and the type of malocclusion in the stability of anterior open-bite (AOB) correction over the long-term. Methods:The systematic search for studies was conducted through MEDLINE, CINAHL, EMBASE, Scopus, PsychINFO, various key journals, and review articles; November 30, 2016, was the last date for the search. The Quality Assessment Tool for Quantitative Studies was used to grade the methodological quality of the studies.Results: The present review included 14 studies. Stability of the corrected AOB ranged from 61.9% to 100%. The studies with orthognathic surgeries showed a stability of 70-100%. The studies without orthognathic surgeries showed the stability of 61.9-96.7%. All of the studies were retrospective. The mean change in AOB before (T1) and after treatment (T2-T1) was 0.1 mm to 6.93 mm and the mean change in overbite from T2 to T3 (T3-T2) was −0.06 mm to 2.5 mm. Conclusion:Studies with orthognathic surgeries presented with high amount of long-term stability in corrected AOB. No significant difference was noticed in relation to the type of malocclusion and extraction or non-extraction cases.

“…Several studies have reported successful treatment of such cases by intruding maxillary and/or mandibular posterior segments using miniplate and miniscrew anchorage. [20][21][22][23][24][25][26][27][28][29] A recent systematic review has summarized the studies conducted on this subject. 30 Deguchi et al 27 studied the effect of molar intrusion followed by premolar extraction on several soft tissue parameters.…”

Objective: This study was conducted to determine the effect of premolar extraction and incisor retraction on the soft tissue profile of skeletal open bite adults following maxillary posterior teeth intrusion. Materials and Methods: Lateral cephalometric radiographs of 28 adults with skeletal open bite (age = 22.6 ± 2.1 years) were taken following molar intrusion with zygomatic miniplate skeletal anchorage and after four first premolars extraction. Several soft tissue variables were measured. Correlations, mean ratios and regression equations between the change in lip position and incisor retraction were calculated. Results:Both the upper and lower lips moved backwards by 3.46 mm ± 0.84 mm (P ≤0.01) and 0.87 mm ± 0.23 mm (P ≤ 0.05) respectively, with a significant reduction in the angle of convexity by 1.36° ± 0.24° (P ≤ 0.05). Strong correlations were found between the amount of upper incisor retraction and backward movement of the upper lip with a mean ratio of 1.04:1 (r = 0.812, P ≤ 0.01) and with the reduction of soft tissue convexity angle with a mean ratio of 2.65:1 (r = 0.814, P ≤ 0.01) and between the lower incisor retraction and backward movement of the lower lip with a mean ratio of 0.76:1 (r = 0.802, P ≤ 0.01). Conclusion: The pattern of change in soft tissue profile in this study was similar to studies of premolar extraction without prior molar intrusion. However, the ratio of change of upper lip position relative to the upper incisor retraction was higher compared to ratios reported in the literature which may be attributed to the underlying long face skeletal pattern.
