The Shear Bond Strength Between Milled Denture Base Materials and Artificial Teeth: a Systematic Review

Objectives of Investigation: The data about shear bond strength between digitally produced denture base materials and artificial teeth are scarce. Several studies investigated shear bond strength values between milled denture base material and different types of artificial teeth. The aim of the present study was to compare and evaluate the available evidence through a systematic review, and to enable the selection of optimal material for a given clinical situation. Methods Used: A bibliographic search was conducted in Pubmed, Scopus, and Web of Science to assess adequate studies published up to June 1st 2022. This review followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta- Analyses) guidelines. The studies that determined the shear bond strength values between milled denture base materials and artificial teeth were selected. The search identified 15 studies which were included in PRISMA 2020 flow diagram for new systematic reviews. Studies that scored between 0 and 3 were categorized as being at low risk of bias, studies with score between 4 and 7 as moderate risk, and scores between 8 and 10 as high risk. Results: Only 3 studies met inclusion criteria and according to PRISMA 2020 present moderate risk of bias (score 6). The risk of bias is as follows: single operator of the machine, depiction of the sample size calculation, and blinding of the testing machine operator. The scores for these parameters were basically low (score 2) when compared to other risk of bias parameters (score 0). Conclusion: Bonding agents ensure bonding strength at least similar to the conventional methods. In order to upgrade the quality of future studies, it would be advantageous to use larger number of specimens with standardized dimensions, and blinded testing machine operator to decrease the risk of bias.
