Medical and dental histories, clinical examination, study models, and photographs provide the data for a proper diagnosis and the treatment plan for esthetic dentistry. However, they do not offer all the information necessary to analyze the smile and create harmony with the lips and face without excessive intraoral adjustments. Dentolabial parameters vary according to lip dynamics and are influenced by both a static posed smile and a smile in motion as captured in video. This article describes a documentation protocol using smartphone videos to improve the analysis, smile design decisions, and elaboration of a 2D smile frame that will guide the 3D digital smile design project. The use of dynamic documentation of the smile (DDS) allows esthetic rehabilitative planning from a facial perspective, improvement of communication with the patient, integration between the specialists, and the predictable quality of the treatments.
