Abstract: Objective: To investigate the application of 3D printed cyst plug in the mandibular cystic lesion. Methods: Forty patients with mandibular cystic lesion were randomly divided into the control group and 3D printed cyst plug group. The control group was made with traditional cyst plug, and 3D printed cyst plug group was digitally designed surgical plan and 3D printed cyst plug through a preoperative model and oral examination. Two groups of patients were followed up for a long time. The reduction rate of the cyst volume was compared, and the patients' satisfaction with the cyst plug was studied. Results: The volume of the cyst was reduced in both groups, and the reduction of cyst volume in the first 3 months after surgery was more obvious than that in the next 3 months. The group of 3D printed cyst plug was better than the control group in the comfort (P<0.05) and wearing (P<0.05), but there were no significant differences in the retention between two groups (P>0.05). Conclusion: The 3D printed cyst plug is an effective device to keep the pressure balance of cyst after decompression.
