简要总结
An important consideration to take into account during the planning of orthodontic treatment is anchorage control. Even with the usage of different methods to reinforce anchorage, desired outcomes are not always achieved. Conventional anchorage system predominantly involve the patient’s teeth or depend on their compliance, leading to uncontrollable and often undesirable movement.
Several strategies have been developed to address this crucial issue in orthodontics.
Skeletal anchoring techniques have gained significant among them.
From the utilization of vitalinum screws to conventional osteointegrated implants for orthodontic anchorage, several methods have been used miniplates, onplates, palatal implants, miniimplants.
These serve as valuable tools for achieving treatment goals.
The key benefit of TADs is their provision of optimal biomechanics for both tooth movement and anchorage control, even in uncooperative patients.
The other advantages of TADs are cost effectiveness, simplicity in their in their insertion and removal, and minimal occurence of complications during application.
An early loss or loosening of a miniscrew is considered a failure that hampers therapeutic objectives
Therefore many research focuses on examining variables influencing TADs stability during orthodontic tooth movement.
Factors such as patient’s oral hygiene, oral and systemic conditions, smoking habits, surgical protocol (including implant location), loading technique (duration,force and direction) and type of TAD are among possible factors which might miniimplant failure.
However conducting a compenhensive study of TAD stability is a difficult task therefore the need to establish patient group to ensure accurate findings and recommendations.
Although small diameter miniimplants are convient to use as TADs in the maxilla and mandible they could compromise on primarily stabilty. To compensate for inadeqyuate intial stability in case of inferior bone quality and quantity large diameter diameter and long length implants may be used.
Hence, this study aims to evaluate the impact of diameter of orthodontic miniimplants on their stablity during enmasse retraction of anterior teeth.
