Clinical Longevity of Ceramic Laminate Veneers Bonded to Teeth With and Without Existing Composite Restorations up to 10 Years

Rationale: Survival rates of teeth with laminate veneers were reported to have more marginal caries and discoloration when existing restorations are present. However in these studies no conditioning of the existing restorations was performed. Objective: This study evaluate the survival rate of ceramic laminate veneers bonded to teeth with and without existing composite restorations Study design: Prospectief Cohort research Study population: the participants received laminate veneers and older then 18 years. Intervention (if applicable): The participants received laminate veneers in the past. No intervention. Main study parameters/endpoints: Survival and success of laminate veneers with existing restorations: Survival (no loss of laminate veneer during follow up time), Success was measured using USPHS health criteria. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The participants are asked to come for a check-up of their restorations, the investigators will evaluate the laminate veneers by sight and take some light photo's and a patient questionnaire will be given.
