Clinical Evaluation of Combined Manual Pre-treatment and Negative-Pressure Cleaning for Dental Implant Instrument...

This study evaluates a combined manual pre-treatment and negative-pressure cleaning process for dental implant instruments to improve cleaning quality and efficiency. A total of 200 contaminated dental implant toolkits were randomly assigned to a control group (traditional manual cleaning) or an experimental group (manual pre-treatment combined with negative-pressure cleaning), with 100 toolkits in each group. Cleaning quality was assessed using visual inspection, magnification, residual blood detection, and ATP fluorescence testing, and cleaning time was recorded. The experimental group demonstrated higher qualification rates across multiple indicators compared to the control group, including improved outcomes under magnification and residual blood testing, as well as a higher complete qualification rate. Manual cleaning time was significantly reduced in the experimental group (6.48 ± 2.78 min) compared to the control group (28.94 ± 2.57 min). Although total processing time increased due to automated cleaning cycles, manual handling time was markedly reduced. Overall, the combined approach improves cleaning quality, reduces manual workload, and enhances standardization. This approach enhances efficiency, standardization, and safety in clinical instrument reprocessing.
