Asymmetric severe skeletal Class II division 1 patient with temporomandibular joint disorder treated with zygomatic anchorage devices and Ni-Ti alloy wires

ABSTRACTObjectives: The aim of this study was to investigate the alveolar and symphysis region properties in hyper-, hypo-, and normodivergent Class II division 1 anomaliesMethods: Pretreatment lateral cephalograms of 111 young adult female patients with skeletal Class II division 1 anomalies were compared to those of 54 Class I normal subjects (control group). Class II cases were divided into hyperdivergent (n = 58), hypodivergent (n = 19), and normodivergent groups (n = 34). The heights and widths of the symphysis and alveolus and the depth of maxillary palate were measured on the lateral cephalogramsResults: Mean symphysis width was wider in the hypodivergent Class II group than in the other groups, while mean symphysis height was similar among all groups. Maxillary palatal depth, upper incisor angle, upper and lower molar alveolar heights, and Id–Id′ width were also similar among groupsConclusion: Symphysis width is the main factor in the differential diagnosis of Class II division 1 anomaly rather than symphysis height and hypodivergent Class II Division 1 anomaly is more suitable for mandibular incisors movements.

INTRODUCTION: This article demonstrates the description and use of a new appliance for Class II correction. MATERIAL AND METHODS: A case report of a 10-year 5 month-old girl who presented with a skeletally-based Class II division 1 malocclusion (ANB = 6.5º) on a slightly low-angle pattern, with ML-NSL angle of 30º and ML-NL angle of 22.5º. Overjet was increased (7 mm) and associated with a deep bite. RESULTS: Overjet and overbite reduction was undertaken with the new appliance, Fixed Lingual Mandibular Growth Modificator (FLMGM). CONCLUSION: FLMGM may be effective in stimulating the growth of the mandible and correcting skeletal Class II malocclusions. Clinicians can benefit from the unique clinical advantages that FLMGM provides, such as easy handling and full integration with bracketed appliance at any phase.

Class II, Division I malocclusion has been described as the most frequent treatment problem in orthodontic practice. Aim & objectives of the present case report was to evaluate the management of skeletal Class II division 1 malocclusion in non growing patient with extraction of upper first premolars. Clinical and cephalometric evaluation revealed skeletal Class II with Angles Class II division 1 malocclusion with mild mandibular anterior crowding and increased overjet, severe maxillary incisor proclination, mild mandibular crowding, exaggerated curve of spee, convex profile, incompetent lips, increased overjet and overbite. Maxillary first premolars were extracted followed by en-masse retraction of anteriors with the help of temporary anchorage devices (TADs) to avoid anchorage loss. Mandibular incisor was extracted to correct curve of spee. Following treatment marked improvement in patient’s smile, facial profile and lip competence were achieved and there was a remarkable increase in the patient’s confidence and quality of life.

Class Ii Division 1

A 61-year-old female patient with adenoid cystic carcinoma (ACC) of the right maxilla and Angle class II division 1 malocclusion had received a subtotal maxillectomy in right side and used a conventional clasp-retained obturator. After implants placement, a maxillary interim immediate obturator (IIO) and then a definitive obturator using six endosseous implants were fabricated. During one-year follow-up, the patient was completely satisfied. Ideally, after implants placement in edentulous patients suffering from hemimaxillectomy, an implant-supported obturator (ISO) is designed in order to prevent nasal reflux and to improve speech and swallowing. However, in the following case, because of skeletal class II division 1 malocclusion and implants insertion in the premaxilla, using an ISO was impossible because it would cause excessive upper lip protrusion and lack of anterior teeth contact. Therefore, a five-unit implant-supported fixed partial denture (FPD) was fabricated in the maxillary anterior segment so that anterior teeth contacts were possible and the patient’s normal lip support was achieved. A bar and three ball attachments were used in the maxillary posterior segment. A closed-hollow-bulb ISO was preferred. Conventional ISO in these patients results in several problems. Using a maxillary anterior FPD along with ISO caused satisfactory results in the current patient.

Aim & objectives of the present case report was to evaluate the management of skeletal Class II division 1 malocclusion in non growing patient with extraction of upper first premolars. Clinical and cephalometric evaluation revealed skeletal Class II division 1 malocclusion with severe maxillary incisor proclination, convex profile, average mandibular plane angle, incompetent lips, increased overjet and overbite. After extraction of upper 1st premolars, canine retraction was done which was followed by retraction of severely proclined upper anterior teeth by judicious control of third order bend in rectangular stainless steel arch wire with V loop . For anchorage management, intra oral anchorage with tip back & toe in bends in stainless steel arch wire was satisfactory. Following treatment marked improvement in patients smile, facial profile and lip competence were achieved and there was a remarkable increase in the patients confidence and quality of life.
