Article Synopsis
- - This study evaluates the machinability and machining accuracy of various polymer-based CAM blocks using the ISO 18675: 2022 merlon fracture test model.
- - The tested materials included hybrid disc blanks and PMMA disc blanks, with machinability scored based on the fracture range of merlons and accuracy assessed using CAD data.
- - A thickness of 0.3 mm is suggested for dental applications to ensure better machinability and accuracy, providing guidelines for creating precise dental restorations.
This study was aimed at preparing zirconia samples via additive manufacturing (AM) and subtractive manufacturing (SM) and testing the following aspects: (1) the manufacturing accuracy of the zirconia samples and (2) the bond strength of porcelain to zirconia to evaluate the applicability of the zirconia fabricated by AM in dental clinics. We used three milling machines for SM (AR, K5, and UP) and a 3D printer for AM (AO). The manufacturing accuracy of the zirconia specimen in the internal and marginal areas was evaluated by superimposing techniques to calculate the root mean square (RMS) values.
