The provision of orthodontic anchorage in the adult patient can be compromised due to reduced periodontal support, insufficient number of teeth and limited supra-gingival tooth tissue. Where tooth borne anchorage is unavailable for significant orthodontic movement implants represent a viable alternative. This paper describes the use of dental implants for orthodontic anchorage in a partially dentate patient with a severe unilateral cross-bite where orthognathic surgery was the only other realistic option. The implants were successfully engaged using a composite bridge and a modified quad helix appliance for correction of the malocclusion. Once orthodontics was completed the patient was restored using highly sintered ceramic crowns and bridges. This paper highlights the importance of the multi-disciplinary team and the close liaison between the restorative dentist, orthodontist and technician in treatment planning and provision.
