Molar uprighting

Sunil Sunny, Denny P Joseph, Neethu Mathew, Roshini Sara Rajan, Eldo Kurian
The fixed lingual arches that are used for mandibular molar uprighting works in two dimensions, whereas the 3D lingual arch works in all the three dimensions. The 3D lingual arch was fabricated from a 0.028 "round S.S wire with parts consisting of an adaptor, activator, friction lock and extender. The friction lock was inserted into the vertical stubs welded on the molar bands of the lingually tipped molar. They provided greater stability and anchorage to the molars. Up righting of the lingually tipped mandibular molars was attained within one month after insertion of the Wilson's 3D lingual arch...

Severe skeletal open bites may be ideally treated with a combined surgical-orthodontic approach. Alternatively, compensations may be planned to camouflage the malocclusion with orthodontics alone. This case report describes the treatment of an 18-year-old man who presented with a severe open bite involving the anterior and posterior teeth up to the first molars, increased vertical dimension, bilateral Class III molar relationship, bilateral posterior crossbite, dental midline deviation, and absence of the maxillary right canine and the mandibular left first premolar...

Well-coordinated interdisciplinary dental treatments provide the best esthetic, functional, and long-term results for patients. However, the length of such treatment, which may involve orthodontics, ridge augmentation, and dental implants, often deters patients from pursuing them. The two case reports presented here aim to present the advantage of simultaneous orthodontic molar uprighting and ridge augmentation procedures for future implant site development. Selective decortication of the alveolar bone, performed simultaneously with bone grafting, can accelerate the tooth uprighting process and synergistically reduce treatment duration...

PURPOSE: Impacted mandibular second molars can cause caries and root resorption on adjacent molars and can lengthen orthodontic treatment. Surgical uprighting is one management option. The purposes of this study were to 1) evaluate radiographic outcomes for surgical uprighting of impacted mandibular second molars and 2) propose an etiology for impaction. MATERIALS AND METHODS: This was a retrospective cohort study of patients who had surgical uprighting of mandibular second molars and had preoperative and at least 12-month postoperative panoramic images and an age- and gender-matched control group of patients undergoing routine orthodontic treatment...

INTRODUCTION: The aim of this study was to determine the effects of the leveling of the curve of Spee in subjects treated with preadjusted appliances in different skeletal vertical patterns. METHODS: The study sample consisted of 90 white patients (39 male, 51 female; age, 19 years 4 months ± 1 year 9 months), with a curve of Spee of 2 mm or greater before treatment. They were categorized into 3 groups: low-angle group (30 subjects; 12 male, 18 female; age, 19 years 1 month ± 1 year 4 months), normal-angle group (30 subjects; 14 male, 16 female; age, 19 years 6 months ± 2 years 1 month), and high-angle group (30 subjects; 13 male, 17 female; age, 19 years 7 months ± 1 year 5 months) by their vertical facial types...

A 22-year-old woman came with a unilateral missing mandibular first molar and buccal crossbite. The open space was closed by protraction of the mandibular left second molar and uprighting and protraction of the horizontally impacted third molar using temporary skeletal anchorage devices, and her buccal crossbite was corrected with modified palatal and lingual appliances. The total active treatment time was 36 months. Posttreatment records after 9 months showed excellent results with a stable occlusion.

INTRODUCTION: When the mandibular permanent second molar becomes impacted, it is identified as a malocclusion that needs treatment as it often leads to unwanted complications such as caries and periodontitis of the adjacent permanent first molar. Other less common complications include root resorption of the adjacent first molar root or continued root development to be in close proximity to the inferior dental alveolar nerve. MATERIALS AND METHODS: This paper seeks to differentiate various levels of severity of impaction and review treatment options that are considered clinically available for the proper management of the impacted mandibular permanent second molar...

UNLABELLED: Revalence of impaction of mandibular permanent second molars is between 0.06 and 2.3 percent. In order to reduce treatment time and complications associated with tooth impaction, intervention should take place once the problem is detected. The usual treatment options consists of surgical exposure, luxation of the impacted tooth, extraction of adjacent third molar, orthodontic treatment, and uprighting with brass wires or mini-screws. AIM: The present paper reports a case of bilateral impaction of mandibular permanent second molars ' (MM2s) treated with extraction of the mandibular third molars (MM3s) and surgical-orthodontic uprighting with the brass wire technique...
