Premium protocol for planning a periodontal-restorative approach: Conservative, predictable, and reproducible

Planning oral rehabilitation that involves an interdisciplinary approach is challenging, especially when it includes changes in the morphologic aspects of teeth and the architecture of gingival tissues. Patients commonly complain about the esthetics of maxillary anterior teeth, especially when diastemata are present. A guideline known as the golden proportion can be used to establish adequate width distribution of anterior teeth. Tooth proportion is also affected by incisogingival tooth length, hence gingival contouring should be evaluated as well. In these situations, the width-to-height ratio of 0.75:0.78 in the maxillary anterior teeth could be used to obtain wax-ups and a surgical guide, resulting in a more predictable esthetic outcome. Therefore, this clinical report describes a protocol for the planning of a periodontal-restorative approach with two wax-ups and a surgical guide using the golden proportion width-to-height ratio of 0.75:0.78 for the treatment of maxillary anterior teeth with diastemata using minimum thickness lithium disilicate veneers.
