Periodontal and restorative considerations with clear aligner treatment to establish a more favorable restorative environment.

Abstract

Although standard fixed appliances are better suited to control difficult tooth movement in three planes of space, clear aligner orthodontic treatment may be requested by patients because of the superior esthetics compared with conventional fixed appliances when clear aligners can be considered. Several clinical trials have shown improved periodontal status during orthodontic treatment with clear aligners while fixed appliances have almost always been associated with increased inflammation and mild periodontal breakdown despite preventive measures performed during treatment. There have been no reports of decalcification and only one reported case of root resorption with clear aligners, whereas with fixed appliances, numerous incidents of both decalcification and root resorption have been reported. In addition, studies have also shown significantly less pain from soft-tissue injuries and muscle soreness from parafunctional habits with computer-aided clear aligners. Restorative advantages include improved esthetics and comfort during treatment for better case acceptance and the ability to bleach teeth throughout treatment. Improving tooth alignment with orthodontic treatment with fixed or clear appliances increases the clinician's potential capability to perform more conservative restorative procedures, requiring less tooth structure removal and less endodontic involvement because of better tooth positions. In those cases in which clear aligner appliances may be appropriate, less damage may occur to existing porcelain restorations than might transpire from bonding of fixed appliances and their removal, as well as potentially reduced tooth wear during treatment. This article presents three case reports that demonstrate the periodontal and restorative aspects of treatment using the computer-aided clear appliances, which have either eliminated the need for certain restorative procedures or created a better periodontal and tooth position environment for performing these procedures.
