Combining DIgital Smile Design with Kois Dento Facial Analyzer: Optimising Esthetic while Preserving tooth Structure
This case of an adult male patient with missing maxillary lateral incisors who was unhappy with his smile focuses on implementation of the digital smile design (DSD) concept. Combined with the use
of a dento-facial analyzer, DSD, which employs a series of extraoral photographs, allowed the clinician to preoperatively plan different approaches to the treatment and visualize the outcome of each one, as well as to effectively communicate critical tooth position references to the laboratory technician and the patient. The additive approach used in this case minimized tooth preparation while creating an esthetic smile.

Preoperative close-up view showing excess spacing in the maxillary anterior regionPreoperative view of the patient as he presented with concerns about an unattractive smile. The facial midline marked using DSD. Close-up view with the interdental ruler in place showing the position of tooth No. 8 in the facial midline The existing tooth positions could be accommodated with minimally invasive preparations if the dental midline was shifted 2 mm to the left (as indicated by green line)Photograph showing the changes proposed to the length of tooth No. 8 (lengthen 1.5 mm), No. 9 (lengthen 1 mm), and No. 10 (shorten 1 mm). Photograph showing that the new width of the central incisors will be 9.5 mm. he 12 o’clock view photograph, taken from the top of the face, provided a view of the upper incisor position, which is recommended to be at the wet border of the lower lip. In this case the central incisor edge will be moved labially 1.5 mm.Placement of the dento-facial analyzer to record the occlusal plane orientation.The maxillary cast mounted against the platform. The 9.5-mm incisor width index tray was selectedThe technician was able to efficiently fabricate the wax-up by using the proportion guideThe trial smile in place.Minimal prep with 0.3 mm chamfer Periodontal surgery completed via laser treatment. Postoperative close-up view of the maxillary anterior teeth.Full view of the successful new smile.This case was published in Compendium Jan 2016. you can download in google scholar.
