Failure Analysis and Preventive Maintenance Framework for Dental Treatment Units in a Specialized Oral Hospital
Abstract: This study analyzes common failure patterns in Dental Treatment Units using 1744 maintenance records from a tertiary oral hospital over 24 months. Failures were classified through subsystem analysis and prioritized using Pareto analysis, identifying five components responsible for most maintenance events. Based on root cause analysis, targeted troubleshooting procedures and a tiered preventive maintenance framework integrating TPM and condition based maintenance were developed. Implementation reduced downtime, lowered maintenance costs, and extended service life. The findings provide practical evidence for optimizing DTUs maintenance management in specialized oral healthcare institutions.
