Abstract

The excessive gingival display is anesthetic problem that can affect patient simile. This aesthetic unwelcome issue can be caused by altered passive eruption and a surgical treatment can be required. The diagnosis and treatment plan are performed in these cases by using a manual probe, the cementenamel junction is located, and the gingival excess evaluated. However, this procedure is complex, and an experienced examiner is required to perform it properly. Based on it, the cone-beam computed tomography (CBCT) technique became an interesting alternative approach. The aim of this study is present a 6 months follow-up case of aesthetic crown lengthening guided by CBCT. According to the case reported above, the cone-beam computed tomography wearing a plastic lip retractor is a useful and predictable tool in the diagnosis and planning of aesthetic crown lengthening surgery.
