The current evidence and implications of lingual orthodontics

Abstract

The purpose of this review is to investigate the current evidence and implications of lingual orthodontics. The electronic database search was done on PubMed, Cochrane Library, Embase, EBSCOhost, Web of Knowledge, and Google Scholar reporting on appliance design, bonding, and laboratory setup, biomechanics, survey studies, case reports, and treatment outcomes to find the current evidence of lingual orthodontics. The evidence available on lingual orthodontics traces a very clear and predictable pattern. The 80's was devoted to the limitation and progression of the concept; the 90's to the comparison between labial and lingual and the evolution of laboratory technique and bracket system. The last decade focuses on innovations, the predictability of outcomes, the impact of white spot lesion, and the patient acceptability. This review also shows that biomechanical principles of lingual orthodontics are well understood and established today, any case that can be treated with labial orthodontic appliance, can also be treated effectively with lingual orthodontic appliance as the completely customized lingual appliance can provide predetermined treatment outcome.
