No-preparation ceramic veneers: a systematic review
Aim The main objective of the present systematic review was to investigate the validation of no-preparation ceramic veneers as restorations.
Materials and Methods Pubmed, Evidence-Based Dentistry, BMJ Clinical Evidence, Embase, Dynamed and Opengrey were analyzed in order to identify randomized controlled clinical trials evaluating the clinical outcomes of no-preparation ceramic veneers; manual researches were performed as well.
Results Database search produced 2551 records. After removal of duplicates and a careful examination of titles and abstracts, the reviewers excluded all of the studies. Manual and grey literature did not yield any other relevant article.
Conclusions Due to the lack of data, at the moment achieving a definitive clinical statement regarding the “no-prep” technique is not possible. Further clinical studies are needed to assess the effectiveness of no-preparation ceramic veneers. No-prep veneers can be considered as conservative treatments which should be carefully recommended and request a cautious selection of cases. Further controlled clinical researches are necessary to clearly identify predictable clinical protocols and evaluate the long-term outcomes of such restorations.
