CONSERVATIVE PORCELAIN VENEERS WITHOUT DRILLING – NO-PREP VENEERS
Teamed with world famous ceramist Matt Roberts CDT, our office is proud to announce the development of “No-Preparation” or “Minimum-Preparation Veneer” systems, the newest most advanced conservative dental restorative product in the world today. One of the newer innovations in cosmetic dentistry is
the technological development of dental porcelains used for porcelain veneers or porcelain laminates that can be created ultra-thin (as thin as 0.2mm) and still be strong and durable. Low preparation means only a small amount of drilling or tooth reduction is performed. No or low-preparation veneer styles still allow Dr. Fondriest to restore smiles with natural contours (not thick or overcontoured) with zero or minimal tooth reduction! Most veneer porcelain types are extremely brittle and will easily break during the bonding process when made thinner than 0.5mm thickness. This new non-brittle porcelain can be made in especially thin sheets that will bond without cracking. The healthy tooth enamel is maintained. In many cases no anesthesia is required to create and deliver these beautiful restorations.
Unlike the similar highly marketed product, Lumineers™, our no or minimal reduction versions can be built with multiple artistic layers with varying colors and levels of translucency of porcelain as opposed to the single colored one-dimensional Lumineers. Much greater and natural esthetics can be achieved with no removal of enamel.
Many patients are uneasy and hesitant about having any enamel removed, especially when the teeth are in a healthy condition. No-preparation or low-preparation laminates offer the conservatism of composite bonding while delivering the durability and beauty of regular porcelain veneers. These paper-thin translucent ceramic sheets are basically show-through and manifest a contact lens effect, allowing the normal color of the natural enamel beneath to come through while fixing any imperfections or blemishes and improving the overall shape and symmetry. This type of restoration is especially useful when the teeth are too small, due to wear or genes.
What determines how much tooth reduction or drilling is needed to do a porcelain veneer?
The amount of reduction is a factor that needs significant discussion when planning your treatment choices. The amount of tooth reduction should be matched to your goals and priorities. There are positives and negatives with both heavy and light enamel removal which significantly affect the quality of outcome. Veneers with minimal reduction are a good choice when modest improvement in symmetry and tooth alignment is desired as well as making a more uniform surface morphology. The best cases for the more conservative designs are those without diastemas (gaps or spaces between the teeth), no gingival recession, or loss of gum papillae (black triangles). Conservatively prepared laminates are not a good choice when the goal is to change the brightness of the teeth.
If the case selection is not ideal, minimal-preparation laminates can be more technically challenging for the practitioner and the technician than with conventional designs. The practitioner is responsible t
o control undercuts, create a line of draw, and
to hide margins. Significant improvements in outcome can be achieved with small amounts of tooth preparation to create a margin, to open buccal and incisal embrasures, to ensure a line of
draw, and to round out sharp edges.
The Philosophy of Minimally Invasive and Conservative Dentistry
Respecting the value of the original natural tissue. Said another way, nothing artificial is as good as what Mother Nature has created. Dr. Fondriest tries to do the minimum necessary to restore your teeth to their natural healthy condition. When doing optional cosmetic driven dental restorations, the doctor will do as little drilling as possible to fulfill the goals of the procedure. This is especially important with elective cosmetic care. Many dentists will drill teeth down to small stumps when it is not necessary. Because nothing is permanent, the heavy loss of tooth structure precludes multiple replacements and it limits future restorative options. Our goal is to limit the amount of drilling to the minimum, helping our patients keep their natural teeth in a healthy state throughout their lifetimes.
Advantages of Normal Preparation Over Low Preparation
- The ability to drill improves the ability to make the teeth straight and symmetrical
- More control of buccal/lingual placement of incisal edges
- Better control of midline alignment
- Shade changes are easier without creating unnatural opacity
- Less bulky emergence contours, especially on the cuspids
- It is easier for the dentist to place the restorations with multiple lines of draw
- Less technique-sensitive for the dentist and technician
- Easier to hide margins or the edges of the restorations
- More symmetrical shapes, especially of lateral incisors
- Nicer surface textures
- Nicer incisal characterization
