Veneer Replacement DentistryAdvancements in Veneer Fabrication - Bonding ChemistryAs discussed in detail on our Veneer page, porcelain laminates are being used in more and more creative ways to address a number of cosmetic issues and, for some patients, even dental function problems related to bite and occlusion.
Advancements in bonding chemistry have increased how veneers can be bonded to different types of tooth structure with differing degrees of "health" of each tooth. In many instances, bonding chemistry has enabled some veneer dentists to accelerate the bonding process. Veneers Gone Bad: Bonding versus Product FailureIt is becoming well known that a bad experience with dental veneers is typically not a product failure.... but rather a failed bonding relationship between a particular tooth and veneer.The quality, integrity and strength of each veneer bond is dependent upon several factors... not just the cement product.. as many patients assume. Anatomy of a Dental BondFactors that determine how strong and permanent a particular bond will be can include: the location of the tooth (anterior-posterior), rotational factors (crooked-turned position), quality of existing tooth enamel, dentin health, contamination factors (saliva, breath, operatory air quality), bonding cement characteristics (traditional versus one-step, specialty cements for compromised dentin, colorized, stain blocking agents, etc) and lastly, bite and occlusal factors that for some patients... can cause veneers to fail repeatedly for certain types of bites.
Technique Sensitive - Experience RequirementsBonding chemistry provides a wider range of restorative procedures that dentists can perform today, compared to just a few years ago. But... the factors that play a determining role in how well a veneer endures hasn't changed much.As with many technologies, practitioners who were proficient with early versions of a technology tend to acquire advanced abilities to apply the technology as advancements occur. In short, technical expertise increases. Unfortunately however, many advancements create the impression that the application of it becomes "easier." Patients, and even some dentists, assume that the "process" of veneer bonding can be quicker. Instant Makeovers, a term popularized on TV makeover shows, may be partly at fault. Veneer treatments frequently fail because of certain protocols (steps) not being followed or the alloted time frames for completing each step is shortened. Reasonable ExpectationsPatients, first of all, should assure themselves that their favored dentist has documented evidence (before and after pictures) of treatment needs and results similar to what is being sought. Many different brands of porcelain are used by different dentists.Since different veneer products have different cosmetic and structural qualities, make sure the favored dentist has the resources to create the cosmetic and/or dental function desired. If treatment involves 4 or more veneers, expect, and moreover, require, to have impressions and stone models made that enable you to "sculpt" the cosmetic effect you want... with precise detail. Occlusal issues should be closely monitored by the dentist. Maintaining a watchful eye on bite characteristics that undergo unwanted change prevents veneer failure that is caused by unusual physical forces that are out of balance in the occlusal plane. The diagnostic waxup (created by the patient and the dentist) creates the veneer temporaries that should be worn for several days to assure the veneers look good, feel good, don't disturb or change bite characteristics, produce no signs of sensitivity, have the desired Smile Line and proportional sizing desired. Veneer temporaries can and should be a tool used by the patient and dentist to assure all cosmetic and functional goals of treatment are being met. There is no substitute for wearing and "trying in" of temporary veneers. Patients with uneven gingival tissues or certain gummy appearances that may become more evident with new veneers should discuss additional treatment before the final veneers are placed. In our office, Dr. Marinic works closely with each and every veneer patient, to assure every critical step is initiated and completed, to the patient's satisfaction ... and to the doctor's satisfaction. All cosmetic and functional characteristics of each veneered tooth structure are evaluated on a unit by unit basis, and on an occlusal plane basis (bulk of unwanted bite changes occur if this step is not followed). Replacing Veneers - RepairVeneers that require replacement, as in the case of normal wear and tear (10-20 years of service), can be replaced with a choice of many new veneer products. The cosmetic qualities of today's veneers offer more dramatic results for many patients.Repairing or fixing a veneer(s) is possible for single or multiple veneers. Most repair issues arise from a failure of not following a particular step, as outlined above, or skipping certain steps altogether. Bad cases of inadequately prepared bonding surfaces may require special preparations or the use of hybrid bonding methods, depending upon the original cause of failure. Porcelain jacket veneers can be used to effectively treat certain occlusal issues that have caused failures. Laminated jackets also work well in managing certain types of tooth sensitivity issues Questions?Veneer dentistry enables many experienced dentists the ability to recreate or create, for the first time, cosmetic and occlusal properties that Mother Nature overlooked. Given diligent control or management of potential failure factors, veneers can reasonably be expected to endure 10 to 20 years or more.Veneer Dentistry offers patients an almost unlimited ability to recreate or create almost any type of smile or smile line change imagineable, provided that recommended procedures are followed closely. Failures do occur however, most with some degree of predictability when certain protocols aren't followed. Persons with a special veneer issue or cosmetic issue that isn't addressed on this page or our veneers page are invited to contact Dr. Marinic directly with their questions. Use our convenient on-line Consult Request form or the Ask The Dentist form. Dr. Marinic will respond to you directly with the answers or information you need to make an informed decision.
