“…The second treatment option was intrusion of the posterior teeth to correct the anterior open bite. Therefore, molar intrusion considered to be the best treatment choice because it leads to an autorotation of the mandible in the counterclockwise direction, thus improving the long anterior facial height (11,12) . However, intrusion of posterior or anterior dentition is always difficult to achieve without the side effect of extrusion of the anchorage teeth (12)(13)(14)(15)(16) .…”

“…If it is possible to orthodontically intrude posterior teeth, the accompanying changes in occlusal plane, mandibular plane, lower anterior face height, and anterior dental overbite would close the patient's open bite. However, intrusion of posterior or anterior dentition is always difficult to achieve without the side effect of extrusion of the anchorage teeth (10)(11)(12)(13)(14)(15)(16)(17) .…”

Corticotomy for Correction of Skeletal Anterior Open Bite Using Miniplates as Skeletal Anchorage (A Clinical and Cone Beam Comparative Study)

et al. 2017

Objective: This study was designed to evaluate the effect of corticotomy and miniplates' usage as skeletal anchorage for maxillary molars' intrusion during correction of skeletal anterior open bite (SAOB). Patients, materials and methods: A sample of 22 patients with an age range from 14 to 22 years, suffering from skeletal anterior open bite with increased posterior maxillary vertical height. The participants were randomly divided into two groups according to the corticotomy approach. Group I: both buccal and palatal corticotomies were performed. Group II: only buccal corticotomy was performed. Buccal miniplates and palatal mini-screws were used as skeletal anchorage for maxillary molars' intrusion assisted by corticotomy. The measurements, including maxillary dento-alveolar heights (mm), bucal crestal alveolar bone heights (mm), bucco-palatal angulations (B-P˚) and mesio-distal angulations (M-D˚) of right and left maxillary first permanent molars, 4.5 months after intrusion commencement. Results: The dento-alveolar height as well as the buccal crestal alveolar height decreased significantly after intrusion in both groups (p≤0.001 and p≤0.05, respectively), but without significant differences between them. Similarly, the M-D and B-P angulations increased significantly after intrusion in both groups (p≤0.01 and p≤0.001, respectively), with no significant differences between both groups. Conclusions: The current corticotomy approaches and temporary anchorage devices (TADs) were similarly effective for maxillary molar intrusion in cases of (SAOB), but complete correction of SAOB was not achieved. Both the posterior maxillary dento-alveolar and buccal crestal alveolar bone heights diminished similarly in both corticotomy methods. Neither mesio-distal nor bucco-palatal angulations of maxillary first permanent molar crown revealed major changes in matching both approaches of intrusion.

“…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.

“…2,3 The anterior open bite is one of the most challenging cases to treat in adult patients. 4 Several surgical and non-surgical treatment approaches have been used to manage these cases. Surgical treatment approach involves maxillary impaction allowing forward and upward rotation of the mandible which decrease the lower anterior facial height and correct anterior open bite.…”

Aim: This case report aims to demonstrate the successful utilization of zygomatic miniplates in the treatment of an adult patient with anterior open bite (AOB). Background: During treatment of anterior open bite, incisor extrusion may compromise facial esthetics in cases with long facial height and/or sufficient incisor exposure at rest and smile.The intrusion of posterior teeth has the advantage of correcting vertical dimension and maintaining proper incisors show. Case description: The patient, a 22-year-old boy, had an anterior open bite of 4.5 mm with increased lower facial height, bilateral posterior crossbite, and two different occlusal planes in the upper arch. Titanium miniplates were used to intrude maxillary posterior teeth with a trans-palatal arch appliance to limit buccal tipping.The intrusive force was then applied through elastomeric chains placed bilaterally in the maxillary arch between the miniplate and posterior teeth.The anterior open bite was corrected within 7 months of intrusion with decreased lower facial heightand significant improvement in anteroposterior jaw relationship. Conclusion: This report emphasizes the significant role of facial appearance and smile. Clinical significance: Most of the non-surgical approaches are not suitable for open bite correction in cases with long facial height and/or sufficient incisor exposure at rest and smile because of their extrusive mechanics which compromise the facial and smile esthetics. The intrusion of posterior teeth using min iplates allowing a counterclockwise rotation of the mandible to correct anterior open bite without compromising facial esthetic and smile.
