An interdisciplinary treatment to reshape upper anterior displaced teeth by using dynamic occlusal recording with an intraoral scanner

Abstract

AbstractObjectiveThis article describes an interdisciplinary treatment that helped a patient with displaced upper anterior teeth. A gingivectomy, root canal therapies, digital smile design, digital wax‐up, and guided tooth preparations were applied.Clinical ConsiderationsA patient with pathologically migrated teeth asked for treatment without orthodontic involvement due to a primary failed orthodontic treatment history. A smile photo was taken and superimposed with the dentition in a CAD software to accomplish a digital smile design. The jaw movements were recorded with two different methods, a mechanical articulator and an intraoral scanner with Patient‐Specific‐Motion function. The occlusal contacts during protrusive and lateral movements were compared and the digital wax‐up was designed according to the later occlusal data. An aesthetic crown lengthening and pre‐op root canal treatment were carried out in advance accordingly. After guided tooth preparation with a silicone index, the final fixed restorations were manufactured and cemented. A 2‐year follow‐up showed that our prosthesis functions well.ConclusionsThis clinical report revealed that an intraoral scanner with Patient‐Specific‐Motion function can effectively record individual dynamic occlusal patterns and these data can be integrated into the CAD/CAM process to enhance the fulfillment of clinical requirements.Clinical SignificanceThis clinical procedure with a 2‐year follow‐up demonstrated that a prosthodontic‐based interdisciplinary treatment of pathologically migrated teeth using dynamic occlusal recording with an intraoral scanner could achieve satisfactory esthetics in a relatively short treatment period. The Patient Specific Motion module may be used to record a personalized functional movement and the data can be integrated into the design process of the final restorations.
