“…In addition, incisor extrusion is a therapeutic alternative for anterior open bite. In several published case reports, the authors used two or four buccally placed mini-implants to achieve molar intrusion and bite closure [ 12 , 16 ]. Our treatment plan involved for the placement of just one mini-implant in the palate's front region, which decreased treatment costs, improved circumstances for maintaining oral hygiene, and reduced the possibility of implant loss compared to buccal placement.…”

A 26-year-old woman had a masticatory dysfunction, straight profile, retrognathic maxilla and mandible, and Angle’s class I with a tendency to class III malocclusion on both sides, with bilateral posterior crossbites and a 4 mm anterior open bite. Orthognathic surgery and orthodontic camouflage with and without tooth extraction were considered as treatment options. The patient’s preferred method of treatment was orthodontic camouflage without extraction. The transpalatal arch had been placed for the bilateral molars’ derotation. After 3 months, the upper segmented fixed appliance was implanted to address the posterior crossbites in the premolar’s region. One mini-implant was inserted into the anterior palatum after the transpalatal arch was removed, and a supporting device was attached to the first permanent molars to give indirect skeletal stability. Orthodontic treatment’s active phase lasted 23 months, and all treatment objectives were achieved during that time: the desired facial profile, adequate occlusion, appropriate overbite, and overjet.

“…Open bite is indeed a common issue in the adult Class III population. Camou age treatments may be applicable in speci c cases, encompassing the utilization of diverse techniques like intermaxillary elastics [12,14], miniplates or extra-alveolar mini implants [24,25], premolar extractions, NITI modi ed curved archwires [26], and the MEAW technique [7,[12][13][14]24]. Mini implants can be used to intrude posterior teeth effectively without extruding anterior teeth or increasing lower facial height [25].…”

Background: Orthodontists believe that temporomandibular disorders (TMDs), as a group of multifactorial diseases, should be carefully examined before treatment, closely monitored during the process, and maintained stably after treatment. Stabilization splint, as a traditional treatment method, owns the characteristics of low cost and risk compared to joint surgery. This treatment combines traditional stabilization splint and multiloop edgewise archwire (MEAW) techniques, aiming to treat complex clinical cases through non-surgical and non-invasive methods to achieve relatively stable orthodontic outcomes. Case Presentation: This case report illustrates the two-phase treatment of a 17-year-old male patient characterized by an anterior open bite, Class III malocclusion, mandibular deviation, and severe temporomandibular joint symptoms. In phase one, the patient was provided with a stabilization splint for a duration of 9 months. This initial phase aimed to alleviate symptoms and reposition the condyle by eliminating the locking relationship between the upper and lower teeth, while establishing a new muscular and articular balance. In phase two, the patient underwent multiloop edgewise archwire treatment, which involved the use of a reverse-curve archwire, short class III traction, and anterior vertical traction. After 26 months of treatment, a functional and esthetic occlusion, normal overjet and overbite and a relatively well-balanced facial profile was established. After a 6 years post-treatment follow-up, the results of this case have demonstrated long-term stability. Conclusion: The report provides substantial evidence supporting the effectiveness and long-term stability of the MEAW appliance in managing these complex clinical scenarios.

“…TADs (mini-screws and plates) have been shown to successfully treat AOB by molar intrusion through skeletal anchorage. 8,9 Surgical techniques for the correction of skeletal AOBs in skeletally mature patients include Le Fort I maxillary osteotomy, bilateral sagittal split osteotomy (BSSO), and bimaxillary osteotomies. [10][11][12] In Le Fort I maxillary osteotomy, impaction of the posterior maxilla effectively raises the vertical position of the molars, which allows mandibular autorotation.…”
