Bad Teeth: Porcelain Veneer Failures |

Porcelain Veneer Failures
Poor bonding procedures, old bonding treatments, bruxing, untreated decay or leakage, inadequate tooth preparation, veneer sizing errors and a failure to monitor eating habits and malocclusion (bad bite relationships) can cause a variety of veneer laminate failures.
Missing, failed or inadequate use of diagnostic wax up modeling with try-in's of veneer temporaries (for multi unit veneer applications) can lead to errors in shaping, sizing, color shading, gumline disturbances that produce cosmetic outcomes not expected by veneer patients.
The graphic pictures below demonstrate some of the more common failures that can occur with laminated teeth.

Concierge Veneers? Cosmetic and reconstructive dentistry is being offered more and more through popular travel marketing companies that promise what can be some astounding dentistry for patients.
Thailand, Costa Rica and Mexico are popular treatment resources for patients in the United States. While we are aware of reports of patients having excellent results.... here is an example of what can go wrong.
Veneer makeover services were marketed on "cost only", made possible by "streamling" the veneer treatment protocol... which essentially means that certain steps in the protocol were eliminated.
No or minimal diagnostic waxup, no matching of tooth prep requirements to match the thickness of the veneer product, no temporary veneer try-ins and quite obviously not even a crude occlusal analysis was performed for this patient.
This chiclette veneer treatment is now being redone with strict adherence to treatment protocols established in the US, which will recreate the appearance of natural teeth with natural sizing.

Substandard Veneer Placement Protocol
Ara Nazarian, DDS |
| Bonding surfaces prepared through the customary tooth preparation procedures are usually maintained by the patient while they are using veneer, temporary try-ins. The same principal applies to temporary crowns. Patients are typically given instructions by the dentist on how to care for the gingival margin areas, learning specifically how to prevent bacteria from seeping into the prepped area of the tooth. This photo depicts what can happen when patients are not diligent about the oral health habits while waiting for the fitting of their permanent restorations. |

Bonding Surface Failures - Veneers

| Broken and fractured porcelain veneers, porcelain veneers falling off, bad bite, bad occlusion, improper tooth guidance, bad dental bonding, improper tooth and bite balance deep over bite, TMJ issues, bruxism and grinding. |

Broken Fractured Veneers - Bruxism
S. Muslin DDS MAGD |
| Patient had veneers provided by a dentist whose "attention to detail" was seemingly poor. The obvious characterstics include poor contour, poor gingival symmetry, too thick - bulky, wrong selection of shade and color, wrong shape, no surface texture (projects appearance of natural teeth), no incisal translucency (natural teeth have a slight transparency at biting edges), opaque finish (flat homogenous color is not natural), grey gumlines, flat incisal edges - fake looking. Treatment (repair) recommendation must include preplanning with study models, diagnostic wax up, temporary guides, and reduction guides to assure patient that beauty and function are maintained (no disturbances of bite and occlusion. Diode laser for contouring gum tissue as needed for natural appearance.

Veneer Cosmetic Failure
Ira Koeppel, DDS |
| Too white, over contoured, poor bonding and leakage around margins, dark gum line, one color (monochromatic) not natural, no incisal translucency, poor gingival fit, black triangles in between teeth. Treatment would require replacement of all veneers with a detailed diagnostic waxup and possible multiple try-in's of different shaded temporaries to assure an accurate selection of shading that provides the best cosmetic result (complement facial and smile characterstics rather than stark contrast), regrowth of papillae.

Veneer Bonding and Cosmetic Failure
Ira Koeppel, DDS |
| Female patient has overbulked veneers and extremely poor contours, very fake looking, opaque color and shading, no opalescence, buck teeth - flared teeth appearance. Because of the overbulked teeth, one can’t see bicuspids in buccal cooridor. No incisal translucency, no symmetry. Treatment to regain a natural appearance would require new veneers with precision diagnostic wax up modeling.

Tooth Preparation and Veneer Sizing Failure
Ira Koeppel, DDS |
A young female patient with flat, opaque looking veneers. Translucency characteristics, a hallmark of a quality veneer treatment is practically non-existant. Technical errors in shade selection, tooth preparation, cementation process and possibly errors in the layering of porcelain during fabrication (amount of layering is usually determined by the dentist). Papilla also lost on some tooth structures
Treatment recommendations could include veneer replacement or bridgework, if teeth have been overpreped.
