Accuracy and efficiency of guided veneer preparation: a narrative systematic review

Aim The aim of the present study is to investigate the studies published related to precision and efficiency of digital versus conventional guided veneer preparation for optimal preservation of the enamel.

Materials and Methods Medline-PubMed, Scopus, and Web of Science were analyzed in order to identify randomized controlled trials. Evaluating the outcomes of guided veneer preparation, manual research was performed as well.

Results A database search produced 1624 records. After removal of duplicates and meticulous examination of titles and abstracts, three papers were included in this systematic review once the reviewers discovered them.

Conclusions  According to available data regarding the guided veneer preparation, it can be considered a conservative treatment for optimal enamel preservation, which does not need a cautionary selection of cases and a skilled dentist. Guided veneer preparation can be enhanced by using additive manufacturing technology. The study concludes that further randomized control trials are needed to assess the effectiveness of guided veneer preparation. In addition, controlled clinical research is necessary to clearly identify predictable clinical protocols and evaluate the long-term outcomes of such guided preparation.
