Purpose: This study evaluated the potential of a vacuum-brazed dental diamond dresser as an alternative to commercially available electroplated diamond dressers and assess its suitability for clinical use.
Methods: Commercially available electroplated diamond dressers were selected as the control group (n=5), whereas vacuum-brazed diamond dressers with 80 grit and 100 grit particles were fabricated as the experimental groups (n=5 each). Prepared specimens were evaluated for surface roughness, wear resistance, and abrasiveness against a wear-inducing element (ZrO₂ ball). The results were reported as means and standard deviations. Statistical analyses were performed using one-way ANOVA followed by Tukey’s HSD test using SPSS Statistics ver. 23.0 (IBM), with the significance level set at 0.05.
Results: Surface roughness was highest in the 80 grit group (23.99±3.62 μm) followed by the 100 grit group (20.38±1.79 μm) and the control group (17.59±0.56 μm). Wear resistance was greatest in the control group (0.0060±0.0009 g) followed by the 80 grit group (0.0018±0.0003 g) and the 100 grit group (0.0013±0.0001 g). Abrasiveness against the ZrO₂ ball was highest in the 80 grit group (0.120±0.007 g) followed by the 100 grit group (0.101±0.007 g) and the control group (0.086±0.004 g).
Conclusion: This study offers key insights for enhancing the performance of diamond dressers through vacuum-brazing and is expected to aid in the development of more efficient and durable diamond dressers for future applications.
