Abstract

The available methods for veneer evaluation are limited to clinical and radiographic examinations, which may not allow the appropriate identification of failure. In this report, we demonstrate the use of optical coherence tomography (OCT) as a noninvasive diagnostic and follow-up method to evaluate gingival recovery and the adhesive interface in aesthetic oral rehabilitation involving periodontal plastic surgery and ceramic laminate veneers. OCT was efficient for evaluating both soft and hard tissues, as well as the quality of the adhesive interface. In conclusion, OCT was found to be a promising approach for the professional evaluation of aesthetic oral rehabilitation, as it was capable of generating images that enabled the analysis of gingival recovery and the adhesive interface.

  Fig. 1 Clinical photographs of the patient. Extraoral (A) and intraoral (B) photographs show the presence of yellowish teeth, generalized anterior diastema, and a gummy smile. C. Mock-up placed on teeth for the clinical simulation of the treatment outcome. The treatment consisted of periodontal plastic surgery, tooth whitening, and cementation of ceramic veneers. D. View of the patient's smile after periodontal plastic surgery and tooth whitening. E. Immediate clinical view after the cementation of the veneers.

  Fig. 2 Sagittal optical coherence tomography images. The cervical (A), middle (B), and incisal (C) thirds of the right maxillary central incisor showing a normal tooth and its surrounding periodontal structures, such as enamel (E), dentin (D), the dentino-enamel junction (DEJ), the cemento-enamel junction (CEJ), gingiva (G), gingival sulcus (S), and incisal border (IB). D. Cervical third of the tooth at 15 days (E) and 60 days (F) after the periodontal plastic surgery demonstrating gingival recovery, given the formation of a new gingival sulcus around the teeth and close contact of the gingiva with the tooth, as shown before surgery. The cervical (G), middle (H), and incisal (I) thirds of the right maxillary central incisor after cementation of the ceramic veneers showing the tooth and its surrounding periodontal structures, as well as the presence of the cementation line (*), bubbles (B), and the laminate veneer (L).
