Molar Uprighting: A Considerable and Safe Decision to Avoid Prosthetic Treatment

Abstract

Background:Tipped lower molar over edentulous space is very common in orthodontics practice when adults seek treatment. The segmented arch technique features a predictable force system that provides a controlled release of force that can produce light and continuous tooth movement.Case Description:A female adult patient, who lost a permanent lower first molar, needed correction of the position of her permanent first molar place. Instead of making space for rehabilitation, it was closed after second molar uprighting and a balanced interdigitation was created without prosthetics. The patient was successfully treated with segmented arch technique using root correction spring activated with geometry VI to promote uprighting of a tipped molar and Niti spring coil to promote space closure.Practical Implications: Segmented arch technique is known to provide predictable light and continuous forces, which is very much indicated in adult treatment. There are several things to consider when orthodontically treating adult patients. Their periodontal conditions might not be ideal, less bone apposition may occur, and side effects of orthodontic tooth movement are expected. Thus, a predictable and controlled orthodontic treatment is needed.

Orthodontic Management of Residual Spaces of Missing Molars: Decision Factors

“…Also, due to mesial tipping of teeth 37, the mesializing movement was performed at the same time as the root correction using a miniscrew-supported spring. Temporary anchorage devices were indeed widely described and reported to be efficient in achieving accurate control of anchorage [15,29] provided that the orthodontists master their biomechanics well. In case 3, as the space of lost 47 was quite large and the orthodontic abnormality not very complicated, the ideal choice was to maintain 47 space and a prosthetic rehabilitation.…”

Camouflage treatment of posterior bite collapse in a patient with skeletal asymmetry by using posterior maxillary segmental osteotomy

“…The second molar protraction enhances new alveolar bone formation during space closure and avoids bone damage mesial to the protracted teeth. 23 The important issue related to occlusal plane canting correction is its stability. Vertical asymmetry correction by maxillary orthognathic surgery is reported to be the most stable.…”

Molar protraction using miniscrews (temporary anchorage device) with simultaneous correction of lateral crossbite: An orthodontic case report

“…There is also evidence that orthodontic movement is an excellent way to reclaim new alveolar bone and soft tissue when closing spaces and avoids crestal bone damage mesial to the second molars after treatment. [ 17 ] Although corticotomy assisted molar protraction is a possibility, limited duration of the corticotomy effect on the rate of tooth movement, if considered within the context of a prolonged treatment time observed with molar protractions appears to be unjustified. [ 18 ] Molar protraction needs high anchorage, and tipping of the molars and root resorption can happen if anchorage is inadequate.…”
