Missing Maxillary Lateral Incisors; What the Restorative Dentist and Orthodontist Should Expect From Each Other

Howard A. Fine, D.M.D.

The Maxillary lateral incisors are an integral part of the smile in frontal view, as part of the "social six" set of teeth. Missing Maxillary lateral incisors is, by definition, a multidisciplinary problem in dentistry because ideal restoration of the smile depends on orthodontic intervention and prosthetics, in order for ideal results to be achieved.

The restorative dental team and the Orthodontist must be in communication throughout the case.  The Orthodontist is expected to prepare the site for implants and/or prosthetics.  The restorative dental team can then place bridges and/or implants to idealize the function and esthetics of the case.

This presentation will focus on techniques designed to idealize site preparation by the Orthodontist and subsequent restorative techniques that are required to maintain the site and prepare for prosthetics, sometimes years later.  More importantly, the presentation will underscore the need for integrated orthodontic and restorative protocols that reduce the need for re-treatment because the site has been compromised.
