the cornerstone of the smile has always been the central incisors.
These are the most visible teeth in the smile
and where symmetry, height-to-width ratio and incisal edge position are critical —making or breaking a good result.
In this article, we will discuss the restoration of both central incisors and how to properly use the software to execute perfect
symmetry, midline and interproximal contacts.
Perfecting Symmetry
With Central Incisors
Creating an Esthetic Result
A 43-year-old male presented with existing crowns on tooth #8
and #9 (Fig. 1). His main goal was to improve the esthetics with
brighter restorations. Tooth #9 had a previous distal fracture that
was repaired with composite resin. When doing the consulta-
tion with the patient in this scenario (replacing central incisor
restorations), the five questions I ask myself are:
• Is the incisal edge in the correct position?
• Is the midline correct?
• Do the teeth have proper symmetry?
