Digital Smile Design

Abstract

One of the important ways of social interaction is through verbal and nonverbal communication. The human face is capable of eliciting multi-response according to the situation; amongst them, a smile plays a significant effect in relaying a positive communication that can immensely influence societal outcomes. An important part of dental treatment is to restore the tooth to functionality and to esthetically rehabilitate it, which forms the core of esthetic dentistry. Modern advancements have led us to various esthetic treatment options. Recently, due to the boom of information technology, we are progressing into the digital age where everything has almost been made through computers and the internet. In the dental field, advanced software is being used to modify and create smiles, thereby completely revolutionizing esthetic dentistry. Digital smile design is a recently introduced concept and software which analyzes the smile of an individual through various input scanners and photographs. They provide a plethora of solutions and predictions as to how the smile can be designed, to the point it can pinpoint minor corrections. Here, we discuss the importance of smiles and the analysis using digital smile design.

After facial photographs uploaded, two baselines are drawn on the center of the slide so that it forms a + sign and The three facial lines are grouped together to analyze the relationship between the lips, gingiva, and teeth

A template tooth is placed over the original photograph so that relationships are established and Drawing the three reference lines that will allow to evaluate whether the intraoral photograph is concurrent with facial baseline data

A rectangle guide representing the ideal tooth proportion is placed over the, teeth thereby comparing the preoperative proportion to the ideal one.[23]

A digital ruler is used to evaluate the esthetic adjustments needed to be done (i.e., crown lengthening, margin placements in the veneers).[24]

The reference lines measured through the ruler are then transferred onto a cast with precision using a caliper device
