Digital smile design is a method that uses photos, video and digital models to plan aesthetic dental treatment. The aim is for the patient and dentist to be able to assess the intended result together before treatment starts.
The principle of the design
Digital smile design looks not only at the teeth but at the whole face. The facial midline, lips, smile line and gum levels are assessed together. Measurements guide the work, but the final design is shaped by the person's facial structure and expectations.
The process step by step
- Consultation: Expectations, concerns and priorities are discussed.
- Records: Standard facial and intraoral photos are taken, along with short videos while talking and smiling.
- Intraoral scan: A three-dimensional digital model of the teeth is created.
- Analysis: The midline, tooth proportions, smile line and gum levels are assessed.
- Digital design: The proposed tooth shapes and positions are prepared digitally.
- Trial (mock-up): Where suitable, the design is tried in the mouth with a temporary material; the patient can assess the new look in the mirror and in photos.
- Treatment plan: The treatments needed to achieve the design (orthodontics, whitening, bonding, veneers, gum contouring, etc.) are set out in order.
How it relates to orthodontics
If the teeth are out of position, the design often requires orthodontic treatment first. The digital planning used in clear aligner treatment can be run together with smile design. This way, if aesthetic restorations are needed, they can be done with less tooth reduction.
How long does the process take?
Taking the records and preparing the design usually takes from a few days to a few weeks. The total treatment time depends on the procedures needed to reach the design; it can be short if only whitening and bonding are needed, and longer if orthodontic treatment is needed.
Things to know
- Digital design is a planning tool; because of biological differences, the result may not match the design exactly.
- The design should be carried out once oral and gum health are in place.
- Treatment options should be discussed along with their advantages and limits.
