Smile Design in restorative dentistry has helped clinicians achieve optimal results for their patients while simultaneously improving their treatment planning skills.
That being said, the three types of scenarios we most commonly hear from dentists when it comes to Digital Smile Planning narrows down to:
Whichever type of dentist you can associate yourself with, digitally planning your smiles helps improve your aesthetic clinical planning and gives the patient a better understanding of the treatment that you propose.
Before starting your journey in the world of Digital Smile Planning, it is necessary to first understand why you are carrying out visual planning before starting the treatment, which is often irreversible.
The primary path is to understand why your patient came to your clinic and know how you can help them have oral health that goes beyond their expectations.
What our patients see is not always the only problem to be solved to ensure the quality of health.
Through clinical exams, photographs, and supplementary imaging examination, we are able to identify the path to why more focused attention on multidisciplinary dentistry will establish more comfort and longevity in the aesthetic and masticatory balance.
Primary care should be done at your first appointment. When you receive your patient, your eyes shouldn’t be focused only on the oral cavity but also on the patient’s face, paying close attention to the way the patients speak and the movements of their mouth and lips.

Most of us have faces that are not symmetrical with the patterns given from scientific articles. This is due to proper genetic functions, posture, or habits. Thus, focusing only on the oral cavity can lead to a mismatch in harmony between the smile and the face and future occlusal balance due to lack of attention on the face. See the example below:
[Figure 1] A frontal facial smiling picture of a patient was taken. With its respective mirror image two other pictures were created: both right sides and both left sides showing that assessment of these images evinces the existing bilateral facial discrepancies.
There are three facial features which do play a major role in the smile design:
And three dental features which also play an important role in the smile design:
[Figure 2] The interpupillary line should be perpendicular to the midline of the face and parallel to the occlusal plane from an anterior view.
[Figures 4-6] And the position of the central incisors should follow the facial imaginary line that consists of the center of glabella, tip of the nose, philtrum (cupid bow) and tip of the chin.
To make these observations, a good photograph of the patient must be taken.
Among the various photographs we took in our field, such as intraoral photos, profile photos, 45 degrees, let’s talk about the frontal image with an open smile to start our orofacial aesthetic analysis.
A photograph of a spontaneous smile must be captured to show the maximum elevation of the upper lip with a spontaneous smile and the mouth slightly opened, to evaluate the parallelism of the curvature of the upper arch with the lower lip helping to identify deviations of the upper and lower occlusal planes in comparison to the face. 
Position your patient standing up straight, with no hats or glasses, and hair tucked behind the ears. In a room with great lighting, frame the patient’s face inside the screen of your camera eliminating shoulders.
[Figure 7] To prevent distortions on the smile curve of the patient’s current conditions, level the lens of the camera to the eyes of your patient and make sure that your camera is straight. Looking at the lens of the camera, ask your patient to give a big wide smile, with the mouth slightly open.
For a more comprehensive treatment plan, using your clinical knowledge, Digital Smile Planning can give you better aesthetic overview and ideal position of teeth in the upper arch in relation to the face for each patient, facilitating the communication with other dentists and involving them in the multidisciplinary treatment workflow. A workflow everyone can benefit from.
