Interdisciplinary management of single-tooth implants

Orthodontists treat many patients who are missing maxillary lateral incisors and/or mandibular second premolars. In the past, if the canines could not be substituted for lateral incisors, conventional full-coverage bridges were the common restoration. Recently, resin-bonded Maryland bridges became a popular substitute for conventional bridges to avoid crowns on the nonrestored abutments. However, resin-bonded bridges have a poor long-term prognosis for retention, lasting on average about 10 years. Since implants were introduced into dentistry by Swedish researchers in the mid-1980s, they have become a promising substitute for conventional or resin-bonded bridges. However, to successfully place and restore single-tooth implants in young orthodontic patients several questions must be answered. This article will discuss the many interdisciplinary issues that are involved in placing and restoring single-tooth implants in orthodontic patients.

Guidelines for managing theorthodontic-restorative patient

Occasionally, patients require restorative treatment during or after orthodontic therapy. Patients with worn or abraded teeth, peg-shaped lateral incisors, fractured teeth, multiple edentulous spaces, or other restorative needs may require tooth positioning that is slightly different from a nonrestored, nonabraded, completely dentulous adolescent. Generally, orthodontists are not accustomed to dealing with patients who require restorative intervention. Should the objectives of orthodontic treatment differ for the restorative patient compared with the nonrestorative patient? How should the teeth be positioned during orthodontic therapy to facilitate specific restorations? Should teeth be restored before, during, or perhaps after orthodontics? The answers to these and other important questions are vital to the successful treatment of some orthodontic patients. This article will provide a series of eight guidelines to help the interdisciplinary team manage treatment for the orthodontic-restorative patient.
