Steps to Success Models - Prep Design - Shade - Bonding |
|
| Porcelain veneers are often the preferred restorative choice for patients who are seeking very aesthetic anterior treatment. A successful case not only restores the treated teeth but often has the added benefit of restoring a smile and the patient’s self-confidence. |
Since we have the benefit of making these types of ceramic restorations every day, we are able to share some tips and information that will help ensure successful results for your patients. The following information covers a variety of subjects from basic to advanced. All are very important for the ultimate success of an all-ceramic restoration. |

| Bonding As a word of caution, check material expiration dates carefully; use only fresh bonding materials. Debonding, breakage, and discoloration are often traceable to old silane primer and occasionally to out-of-date bonding resins. A recurring debond problem is usually caused by a contaminated tooth interface. Pumice and re-etch should solve this problem. |
Models Pre-op, post-op, diagnostic wax-ups and/or acrylic mock-ups are all helpful in communicating proper incisal edge position, contour and basic morphology. Providing this essential information through models will insure that we meet the patient's expectations. |
| Communicate
Shade Provide photos before and after preparation. Select the shade tabs that match the pre-op tooth and post-op preps (stump shade). Position the shade tabs so that they are visible in the photo with the tooth and/or prep. Send us your undeveloped 35-mm roll of film, and we will develop and return your slides or photos with a new roll of film. Or, e-mail your digital photo file to:  Nothing communicates shade and characterizations better than photographs. |
|
| Prep Design DEPTH - Dark stump shades require deeper preparation (0.75-1.0 mm) to enable the ceramist to build a first layer of blocking porcelain (opaceous dentin) and still have enough room for the surface layers of translucent porcelain. Preps with stump shades that closely match the desired finished restoration shade can be prepped more conservatively (0.5 mm). MARGIN - Shallow chamfer margins enable us to provide the best results. Thin slices or bevels don't hold up well to the mechanical etching (sandblasting) and chemical etching (hydrofluoric acid) processes required to fabricate this type of restoration. |
