The orthodontic miniscrew implants in tooth migration

Abstract

Background: The bone loss, tooth loss and gingival inflammation are the most common harmful factors that might cause pathologic tooth migration. Taking into consideration that miniscrews implants are used in orthodontic treatment of both pathologic and physiologic tooth migration, we were interested to mark out the advantages and disadvantages of miniscrew usage. Conclusions: Development of implants industry and particularly miniscrew anchorage has been rapidly increased in the recent years, but nevertheless there still are some risk factors of miniscrews use and success of treatment depends a lot on techniques of miniscrew insertion and stability elements. The anchorage control during tooth movement is one of the main factors for ensuring successful orthodontic treatment and the most important keys for achievement of success in clinical orthodontics. The advantages of miniscrews, in comparison with other methods of orthodontic treatment might be resumed to: lower costs, easy placement, no need for patient cooperation, high quality and efficiency of treatment. Among the most undesirable side effects of miniscrews use can be marked out the screw fracture, screw-root proximity, damages of soft and hard tissues, displacement under orthodontic loading, etc.
