“…The linear and angular measurements of each segment of the entire dentition are important, 2 but, unfortunately, the oblique cephalogram, introduced by Cartwright and Harvold, 20 can bring only one side of the image into focus and, therefore, can only be used to evaluate the morphological characteristics and orthodontic tooth movement in posterior dentoalveolar segments separately on each side. 21 Orthodontic treatments of growing patients with openbite malocclusion have been conducted with one or more of the following appliances: (1) an edgewise appliance, 2,[12][13][14]22,23 (2) vertical elastics, 1,13,14,23,24 (3) high-pull headgear, 2,12,14,22,23 (4) a high-pull chin cup, 2,24,25 (5) a tongue crib, 1,2,26 (6) a posterior bite block, 25,27 and (7) a functional appliance. 28 In contrast, orthognathic surgery combined with edgewise appliance therapy has become widely accepted for adult patients with a severe skeletal open bite.…”

There are very few reports of extensive and detailed cephalometric investigations of nonextraction treatment changes for patients with anterior open bite. The purpose of this study was to evaluate changes in dentomaxillofacial morphology by way of lateral and oblique cephalograms of patients who had undergone multiloop edgewise archwire (MEAW) therapy for anterior open-bite correction. The subjects consisted of 21 Japanese female patients who received MEAW therapy without premolar extraction. The mean pre- and posttreatment ages were 16 years 9 months and 19 years, respectively. Lateral and oblique cephalograms were taken before and after treatment. Fifteen angular and 29 linear measurements were obtained from the lateral cephalograms; 17 angular and 20 linear measurements were obtained from the oblique cephalograms. Treatment changes were evaluated by the paired t-test. The upward and forward rotational changes of the mandible consequent to the use of the MEAWs and anterior vertical elastics were larger than the downward and backward rotational changes of the mandible, due to the extrusion of the posterior teeth by leveling and alignment. The uprighting and retrusion of the premolars and molars, and the extrusion, uprighting, and/or retrusion of the incisors and canines played important roles in the anterior open-bite nonextraction treatment by dint of the MEAW technique.

“…Also, Lawrence et al, [51] placed TPA to help widen maxillary arch, in a class II division I malocclusion patient with deep anterior overbite and facial imbalance. Additionally, in Class II division 1 open bite case, David et al, [52] used TPA for molar expansion in which a soldered TPA with expansion was cemented on the first maxillary molars. Similarly, Mikako et al, [53] reported to treat anterior open bite with Skeletal Anchorage System.…”

The advancement of technology has brought some successful and progressive innovative methodologies in treating orthodontic conditions such as unilateral cross-bite, protrusive malocclusion, molar derotation, dental asymmetry and premature loss of primary molar teeth. The Trans-Palatal Arch (TPA) is such innovative orthodontic treatment methodologies which have shown impressive treatment results. It comprises of stainless-steel bands around the posterior molar teeth and a looped wire that crosses the mouth palate without touching it. This review covers properties, uses and limitation of TPA in treating orthodontic conditions. Regardless of some limitations in the clinical use of TPA yet it is widely recommended for its various functions as advantages outweigh its limitations.

“…5,6 On the other hand, in adult patients attempts are made to physically intrude the molars into their bony support (active intrusion). 4,[7][8][9] Various treatment methods were reported for the correction of anterior open-bites such as: high pull headgear, [10][11] vertical-pull chincups, 6 vertical elastics, [12][13][14] functional appliances 15 and posterior bite-blocks. [16][17][18] In addition to the tongue cribs, 19 transpalatal arches, 20 multiloop edgewise archwire.…”

Objective:Objective: Objective: Objective: The aim of this study is to investigate the effectiveness of the mini-plate zygomatic anchorage for intrusion of maxillary molars in adult skeletal anterior open-bite patients. Materials and Methods: Materials and Methods: Materials and Methods: Materials and Methods: The study group was composed of 10 anterior open-bite patients with posterior dentoalveolar excess. Placement of the mini-plates in the zygomatic buttress was carried out under local anaesthesia. After placement of a double TPA, a closed Ni-Ti coil spring was placed bilaterally between the hook of the mini-plate just mesial and distal to the first molar buccal tube applying intrusive force of 450g per side. Lateral cephalograms and posteroanterior radiographs were taken before intrusion (T1: post upper segmental leveling) and after intrusion (T2). The cephalometric films were measured and compared. Results:Results: Results: Results: The mean amount of accomplished molar intrusion was 3.1mm ± 0.74mm, with a rate of 0.36mm per month ± 0.08mm per month and a bite closure of 6.55mm±1.83mm. Mandibular autorotation followed the molar intrusion, SNB and SN-Pog angles significantly increased while the ANB, MP-SN angle and N-S-Gn angle significantly decreased. There was no significant buccal tip in the right and left molars. Conclusion: Conclusion: Conclusion: Conclusion: Zygomatic anchorage can be used effectively for skeletal open-bite correction through posterior dento-alveolar intrusion.
