Facemasks using tooth-borne anchorages have been used primarily for the treatment of Class III malocclusion with maxillary undergrowth. However, when using a tooth as an anchorage, if the stability of the tooth used as an anchor is weak, the anchoring function may fail as the tooth tilts. Meanwhile, the use of skeletal anchorages such as implants, mini-implants, and mini-plates has been claimed to minimize the side effects of using dental anchorage. This case report describes the treatment of a six-year-old male patient with Class III malocclusion, presenting maxillary undergrowth and mandibular prognathism. Due to the mobility of the anchoring primary teeth, a device using dental anchorage was replaced with that using customized skeletal anchorage for the treatment. Customized guides and miniplates for the surgery were fabricated in advance through a computer-assisted system, in order to avoid possible damage to the adjacent tooth buds. The customized plates were accurately and passively placed on the intended part, showing the desired outcome.

Before the advent of skeletal anchorage distalisation of the lower arch was considered cumbersome. Individual lower molar distalisation followed by retraction into the distalised space created is very time-consuming. Therefore, to reduce the treatment duration lower arch distalisation can be attempted by using buccal shelf screws. Here we present a case of Angle’s Class III malocclusion which has been treated effectively with distalisation of lower arch using 2 buccal shelf screws (2x12mm) with elastic chains following lower third molars extraction. We achieved full arch distalisation of 3.5mm bilaterally in a span of 1.5 months into a class I molar and canine relationship with normal overjet and overbite. Total treatment duration was of 17 months. These results were stable. There were no changes in vertical facial dimensions.

ABSTRACT Introduction: Skeletal Class III malocclusion is one of the most challenging malocclusions to treat. In around 40% of Class III patients, maxillary retrognathia is the main cause of the problem and in most patients, orthopedic/surgical treatments includes some type of maxillary protraction. Objective: The aim of this case report was to describe a treatment method for a patient with maxillary retrognathia and Class III skeletal discrepancy using mandibular and maxillary skeletal anchorage with intermaxillary elastics. Case report: A 13-year-old boy with maxillary retrognathia and mandibular prognathism was treated using bilateral miniplates. Two miniplates were inserted in the mandibular canine area and two other miniplates were placed in the infrazygomatic crests of the maxilla. Class III intermaxillary elastics were used between the miniplates. Results: After eight months of orthopedic therapy, ANB angle increased by 4.1 degrees and ideal overjet and overbite were achieved. Mandibular plane angle was increased by 2.1 degrees and the palatal plane was rotated counterclockwise by 4.8 degrees. Conclusion: This case showed that the skeletal anchorage treatment method may be a viable option for treating patients with Class III skeletal malocclusion.

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.

The Stability

OBJECTIVE: To evaluate the stability of bimaxillary surgery in patients with skeletal malocclusion, with the use of rigid internal fixation. METHODS: Lateral cephalograms from 20 patients, 11 males and 9 females, mean age of 26 years and 1 month, were evaluated before surgery, immediately post-operative and at least 6 months after surgery. Nineteen cephalometric measurements were evaluated, and the results were statistically analyzed by means of the Student's t test and the Kruskal-Wallis test. RESULTS: The Le Fort I maxillary advancement surgery showed almost no relapse. There was lack of stability of mandibular setback, with relapse of 37.33% on point B, due to counterclockwise rotation of the mandible between post-operative periods, occurred by better intercuspation after surgery and muscle adaptation. The results showed the same tendencies for both genders. CONCLUSION: It was concluded that on the bimaxillary surgery treatment of Class III malocclusion, the maxillary surgery was very stable, but the mandibular setback recurred. No statistical differences were found in surgical stability between genders.

The current paper depicts the challenges faced during the treatment of a complicated case of mandibular condylar head fracture, facial asymmetry, and centric relation-centric occlusion (CR-CO) discrepancy along with Class III malocclusion. A 20-year-old female reported with the chief complaint of difficulty in chewing and concern with her appearance due to deviated jaw and had a history of trauma over chin region. The clinical and radiographic examination revealed significant facial asymmetry with long face, right-sided deviation of the mandible, fractured condyle, CR-CO discrepancy, cross- bite with Class III malocclusion, and a missing mandibular single incisor along with non-vital 21 and 22. She was treated with 0.022 MBT appliance along with guiding plane for CR-CO correction followed by asymmetric bilateral sagittal split osteotomy and differential set back on the right and left sides and finally rigid fixation. A good facial profile and functional occlusion were achieved and non-vital 21 and 22 were esthetically rehabilitated with PFM crowns. The stability of surgical as well as orthodontic corrections was excellent and appreciable in the records obtained 2-year post-treatment. When faced with mutilated malocclusion, with multiple problems, sequential correction of functional malocclusion with dental decompensation followed by skeletal correction with surgical approach has yielded a appreciable facial correction with good stability showing 2-year post-treatment follow-up.
