Invisalign treatment of lower incisor extraction cases

Abstract Aim To demonstrate the use of the Invisalign appliance in lower incisor extraction cases. Method Twelve patients, consecutively treated by the removal of a single lower incisor and Invisalign appliances, were selected from the author’s private practice. Pretreatment, treatment and post-treatment photographic records were obtained and are presented. Results All cases completed treatment, with a mean treatment time of 42 weeks. Fifty percent of the cases required a brief period of refinement (average six weeks) at the end of the initial projected treatment period. Conclusion The Invisalign appliance, in correctly diagnosed cases, with careful ‘ClinCheck’ set-ups and good clinical monitoring, can routinely produce satisfactory outcomes in patients who require the removal of a lower incisor.
