MCG School of Dentistry Quality Assurance Manual
Bonding and Veneering
General Guidelines
Bonding and veneering are useful methods to satisfy patient’s
esthetic requirements. They assist the dentist in producing and
enhancing an esthetically harmonious and cosmetically appropriate smile.
Veneers are state of the art; superior esthetics can be achieved and
their permanence is superior to chairside bonding. Bonding is most
appropriate for smaller esthetic changes, such as diastema closure.
Certain aspects of treatment planning demand
special consideration:
-
Diagnostic models, photographs and imaging
techniques are useful as preoperative records and as a means of
planning the definite restoration;
-
Periodontal health should be established
and any periodontal treatment completed before placement of veneers
or bonded procedures.
-
A high caries level is a contraindication
due to the increased possibility of recurrent decay;
-
Occlusal contraindications may include
bruxism, clenching, wear facets, fractured teeth, tooth mobility and
craniomandibular dysfunction;
-
Bonding and veneers are esthetic
enhancements and can be replacements for orthodontic therapy.
Malocclusions remain as such, but can be given a more esthetic
appearance. The patient must be informed when orthodontics is
indicated;
-
The patient must be made aware of the
potential longevity of the chosen restoration and the cosmetic
results they should expect. They do not have the usual longevity of
crowns and may require repair or replacement in the future.
Bonding and Veneer - Quality Evaluation Criteria
|
ITEM |
RATING AND EXPLANATION |
|
|
ACCEPTABLE |
NOT ACCEPTABLE |
|
Operational explanation |
The restoration is of acceptable
quality and is expected to enhance patient esthetics. |
The restoration is not of
acceptable quality. Damage to the tooth and/or surrounding
tissue has occurred or is likely to occur. |
|
Indications |
Bonding or veneers are the
restoration of choice for requested cosmetic enhancement.
Treatment creates no or minimal harm to teeth or adjacent
tissues. |
Restoration was made without
consideration of other treatment possibilities. Special
considerations requiring evaluation are not discovered or taken
into consideration. Restoration may cause damage or adversely
affect the prognosis of the treated tooth or teeth. |
|
Surface and color |
The surface of the restoration is
smooth. No irritation of adjacent tissue is occurring. There is
harmony in color, shade, and translucency between restorations
and adjacent teeth. |
Surface is irregular or fractured.
Color discrepancy is outside the range of color, shade, or
translucency of adjacent teeth. |
|
Anatomic form |
Restoration contours are confluent
with adjacent teeth and soft tissues, and its exhibits
acceptable anatomic form. |
Restoration is grossly over
contoured or under contoured. Contours are contributing to
traumatic occlusion, caries, or periodontal disease. |
|
Marginal integrity |
There is minimal evidence of
marginal discrepancy into which an explorer will penetrate.
Margins are not thick or bulky. |
Marginal discrepancy is evident.
Marginal overhangs are present or contacts are faulty.
Discoloration is found between restoration and tooth structure,
excess cement is present, and restoration is mobile or
fractured. Caries is detected. |
