Application of the radiosurgery assisted gingival displacement technique in the aesthetic area: a case report

Abstract

The use of digital tools offers a new perspective to daily clinical activities even though sometimes different clinical approaches are necessary. This case report of a maxillary anterior rehabilitation demonstrates the application of a gingival displacement technique to enhance the recording of subgingival finish line by means of an intraoral optical scanner (IOS). The temporary restoration was used as a guide for the radiosurgery tip in order to displace the gingiva in a guided and mini-invasive approach. It was then possible to create the space between the tooth structure and the soft tissues for the light beam of the IOS to properly detect the finish lines of the dental preparation. Six single porcelain fused to zirconia crowns were delivered. This technique could be considered as a solution of complex cases with subgingival dental preparation to be detected by means of an IOS.
