Orthodontic correction of maxillary flaring using provisional restorations.

An unconventional orthodontic correction can be accomplished by using preexisting provisional restorations, which can be modified for use in active tooth movement or splinted together for orthodontic anchorage. This technique has an advantage over conventional fixed appliance orthodontic therapy because it can accomplish tooth movement concurrently with restorative and periodontal therapy. Consequently, the timing or sequencing of periodontal and restorative treatment is optimal, and the overall treatment is more efficient. The learning objective of this article is to describe the minor tooth movement necessary to achieve the optimum occlusal scheme, crown form, and tooth position for the forces of occlusion to be displaced down the long axis of the periodontally compromised teeth. Once the occlusion, periodontal health, and crown contours for the provisional splinted restoration are acceptable, the final splinted restoration can be similarly fabricated, and it becomes an excellent orthodontic retainer.
