What is the perfect “smile style” for your new porcelain veneers or porcelain crowns? In my previous article about Smile Design, I discussed that there are over 30,000 different ways that a cosmetic dentist can create a new smile and one of the most popular “smile guides”, Dr. William Dickerson’s “LVI Smile Library”. This article features my other favorite “smile guides”, the Lorin Library, created by cosmetic dentist Dr. Lorin Berland of Dallas, TX. Each smile style is a combination of the teeth shapes for the front six teeth. For example, the four front teeth (incisors) could be either square at the corners (s), square at one corner and rounded at the other (sr), or rounded at both corners (r). Similarly, the cuspids or eye teeth (third tooth back) could be pointed (p), rounded (r) or flat (f). Combining these different shapes each produces a uniquely different smile style. Note that the first smile design on the top left has a r-r-f design, meaning the four incisors are rounded and the canines are flat. Please note, this smile library below is only to choose the basic shape of the front six teeth, and in no way reflect the color, length, surface texture or translucency that the porcelain veneers or crowns will have. Those other things are addressed in other aspects of smile design and choosing the best combination for your “sensational new smile”.
In creating a new smile for you with porcelain veneers or all-ceramic crowns, we could use any of the above 18 smile designs from the Lorin Library or any of the 12 smile designs from the “LVI Smile Library”. However, in general I recommend against smile designs that have the cuspids (third teeth back from the center) too pointy (p) or too flat (f). Pointy cuspids can make the smile look to aggressive and flat cuspids can render an older looking smile. It is so important in the beginning of treatment that my patient involve themselves in an active discussion with me regarding the different smile styles available and which would be most appropriate for them. We take into consideration the age, face shape, personality and a host of other things when recommending one smile style over another. Using our technique called “the trial smile” we’re able to make provisional veneers or crowns so that our patient can “test drive” their new smile prior to making any final decision regarding the smile design for their final porcelain veneers or porcelain crowns. This is very helpful, as many patients are very relieved that they can try out their smile before making their final decision.
