The purpose of this study was to compare the performance of each system by examining the satisfaction of dentists with dental laser and implant engines. 21 dentists at Kyungpook National University dental hospital and the dental clinic in Daegu were selected. A multi-type laser and implant engine system (BLP10/CRB46LN/LSR20NN, Saeshin, Daegu, Republic of Korea), an implant engine system (SurgicPro+/X-DSG20L, NSK, Kanuma, Japan), and a laser engine system (Epic 10/surgical handpiece 6400479, Biolase, Irvine, USA) were used for evaluation. The survey was conducted with 10 items for the implant system and 9 items for the laser system. The blind test was conducted without providing product information. After using each product, the questions were evaluated using a 5-point Likerttype scale and the satisfaction of the dentist was quantified. The statistical significance for product comparison was evaluated using the Kruskal-Wallis test (α=0.05). In the user satisfaction of the implant engine system, there was a significant difference when comparing Saeshin product and NSK product in ‘Cutting force when forming holes’ and ‘Fixability of the drill’ of functional items (P<0.05). In the user satisfaction of the laser engine system, there was a significant difference when comparing Saeshin product and Biolase product in ‘Adequacy of output during soft tissue incision’, ‘Ease to attachment and detachment of laser tip’, ‘Convenience of adjusting the angle of the laser tip’ of functional items (P<0.05). There was a significant difference in ‘Adequacy of handpiece weight’ and ‘Detachable method of laser tip’ in items for laser handpiece design (P<0.05). Each system had a significant difference in satisfaction with function and handpiece design, and improvements for each system could be observed.
