Posterior Discrepancy

Antero-posterior deficiencies are one of the major concerns in adolescents especially when presented with class III malocclusion and anterior cross bite. These discrepancies are generally corrected by protraction of maxilla and expansion during growth period. A 16 year old boy and 12 year old girl presented with midface deficiency with anterior cross bite and Class III malocclusion. Antero-posterior expansion was planned with Hyrax and Jack screw appliances respectively. Anterior cross bite and Class III malocclusion was corrected. Majority of these antero posterior discrepancies can be corrected with antero-posterior expansion, hence are of prime importance.

The aim of this article is to report a case series of a miniscrew-anchored maxillary protraction therapy (MAMP). Two male patients presenting with Class III malocclusion were included in this report. The treatment consisted of a hybrid expander and two miniscrews at the anterior region of the mandible anchoring Class III elastics for maxillary protraction. Effective maxillary length, ANB angle and Wits appraisal increased after treatment. Slight dental effects were observed. MAMP therapy produced substantial skeletal effects and might be a good treatment option for Class III growing patients.

Effective Result

The prevalence of Class III malocclusion in the Asian population is between 9% to 19%. Early treatment for Class III malocclusion can be done with some modified intervention on the growth stage. The inverted labial bow appliance was applied on Class III malocclusion patient in growth period show an effective result. The study showed the effectiveness of inverted labial bow appliance on Class III malocclusion. A 9 years 4 months old girl patient came with unaesthetic problem. Lateral cephalometric examination revealed a skeletal Class III malocclusion (ANB -1°, Wits appraisal -8 mm). Removable orthodontic appliance with inverted labial bow and expansion screw was applied on the maxilla of this patient. The treatment was carried out for 9 months. The result of this treatment was skeletal Class I (ANB 2°, Wits appraisal -4 mm). This procedure was simple and effective to correct the skeletal Class III malocclusion on growth stage patient.

Maxillary hypoplasia is one of the forms of class III malocclusion. On average, 60%  class III malocclusions are characterized by maxillary underdevelopment in all three directions. Anomalies in position, size and the shape of facial bones, maxilla in particular, usually appear in childhood, become more pronounced in adolescence until the end of the growth period. The aim of the paper is to show the camouflage treatment of the patient in adolescence with maxillary hypoplasia. Using the RME method in the upper jaw, extraction in the lower jaw and fixed orthodontic devices in both jaws, a satisfactory result was achieved.

ABSTRACT Objectives To investigate the hypothesis that there is difference in the treatment outcomes of milder skeletal Class III malocclusion between facemask and facemask in combination with a miniscrew in growing patients. Materials and Methods Patients were randomly divided into two groups. In one group, the patients were treated with facemask therapy (FM group: 12 males, eight females, average age: 10 years, 5 months ± 1 year, 8 months). In the other group, patients were treated with facemask therapy along with a miniscrew (FM+MS group: 12 males, seven females, average age: 11 years, 1 month ± 1 year, 3 months). A lingual arch with hooks was fixed to the maxillary arch in both groups and a protractive force of 500 g was applied from the facemask to the hooks. The patients were instructed to use the facemask for 12 hours per day. In the FM+MS group, a miniscrew was inserted into the palate and fixed to the lingual arch. Results Mobility and loosening of the miniscrew were not observed during treatment. Lateral cephalometric analysis showed that SNA, SN-ANS, and ANB values were significantly increased in the FM+MS group compared with those for the FM group (SNA, 1.1° SN-ANS, 1.3° ANB, 0.8°). Increase in proclination of maxillary incisors was significantly greater in the FM group than in the FM+MS group (U1-SN, 5.0°). Conclusions During treatment of milder skeletal Class III malocclusion, facemask therapy along with a miniscrew exhibits fewer negative side effects and delivers orthopedic forces more efficiently to the maxillary complex than facemask therapy alone.

Molar Extraction

A skeletal Class III malocclusion with open bite tendency is considered very difficult to treat orthodontically without surgery. This case report describes the lingual orthodontic treatment of an adult skeletal Class III patient with mandibular deviation to the left side, lateral open bite, unilateral posterior crossbite, zero overbite and negative overjet. The lower incisors were already retroclined to compensate with the skeletal discrepancy. The patient was treated by asymmetric molar extraction in the mandibular arch to retract the lower incisors and correct the dental midline, with the help of intermaxillary elastics. Lingual appliance was used with over-torqued lower anterior teeth’s brackets to control the torque of mandibular incisors. After a 30-month treatment, satisfactory smile and facial esthetics and good occlusion was achieved. A 12-month follow-up confirmed that the outcome was stable. Asymmetric molar extraction could be a viable option to retract mandibular incisors in Class III malocclusion with lower dental midline deviation.

Abstract Background A systemic right ventricle (RV) after atrial switch in transposition of the great arteries (TGA) or congenitally corrected TGA (ccTGA) often results in advanced heart failure in adulthood. Case summary Four patients with INTERMACS Class III underwent durable ventricular assist device (VAD) implantation for a systemic RV. Two patients were diagnosed with ccTGA and underwent tricuspid valve replacement, and two were diagnosed with TGA in childhood and underwent Mustard repair. The two patients with ccTGA received an EVAHEART (Sun Medical, Nagano, Japan) and HeartMate 3 (Abbott Laboratories, Abbott Park, IL, USA) at the age of 56 years and 34 years, respectively. Of the patients with TGA, one received a Heartmate II at age 40 years, and one received a HeartMate 3 at age 40 years. All patients were weaned from cardiopulmonary bypass without subpulmonic VAD support and transferred to the intensive care unit with optimum VAD support. No in-hospital deaths, cerebrovascular accidents, or other major complications occurred. The post-VAD right heart catheter study showed a remarkable reduction in pulmonary capillary wedge pressure in all patients. Discussion The indications for and surgical technique of durable VAD implantation for a systemic RV after atrial switch of TGA or ccTGA have not been fully established. A durable VAD, including the HeartMate 3, was successfully implanted in four such patients in this study. Pre-operative three-dimensional computed tomography images and intraoperative transoesophageal echocardiography guidance helped to determine the positions of the inflow and pump.

Abstract Background Mandibular prognathism (MP) is a craniofacial deformity resulting from the combined effects of environmental and genetic factors. Although various linkage and genome-wide association studies for mandibular prognathism have identified multiple strongly associated regions and genes, the causal genes and variants responsible for the deformity remained ambiguous. Aim This research work was aimed to study the association between polymorphism rs10850110 of the MYO1H gene and skeletal class-III malocclusion in our local population. Materials and Methods Thirty patients with skeletal class III due to mandibular prognathism in the study group and 30 patients with skeletal class I in the control group were selected for this study. These patients were from both sexes and above age 10 years. Based on the cephalometric values, patients were categorized into study and control groups. SNB (angle between sella, nasion and point B at nasion) greater than 82 degrees with an ANB (angle between point A, nasion and point B at nasion) of less than 0 degrees in the study group and ANB (angle between point A, nasion and point B at nasion) of 2 to 4 degrees in the control group were categorized. The polymorphism (rs10850110) of the MYO1H gene was genotyped using polymerase chain reaction and restriction fragment length polymorphism. Associations were tested with SNP exact test using SNPstats software. Results The single-nucleotide polymorphism rs10850110 showed a statistically significant association with mandibular prognathism. The G allele of marker rs10850110 (5′ of myosin1H - MYO1H) was overrepresented when compared with the “A” allele in mandibular prognathism cases (p < 0.0001), and this was very significant. Conclusion These results suggest that the rs10850110 polymorphism of the MYO1H gene is associated with an increased risk for mandibular prognathism.
