BACKGROUND: Three-dimensional printing to prepare a digital model can improve the accuracy of orbital fracture repair, and has a good clinical prospect.OBJECTIVE: To evaluate the effect of individualized titanium mesh based on the digital model in the reconstruction of orbital fracture.METHODS: Twelve cases of orbital fracture were admitted at the Hospital of Stomatology, Southwest Medical University from January 2014 to October 2015. CT scanning in axial, coronal, sagittal planes and three-dimensional reconstruction were performed routinely in all cases preoperatively. Digital model was designed by 3D printing technology according to the CT data. Individualized titanium mesh was shaped based on the digital model and used to repair orbital fracture. The accuracy of the reconstructed orbit was assessed based on the postoperative CT scan.RESULTS AND CONCLUSION: Postoperative CT scans showed that the implanted individualized titanium meshes were capable of accurately reconstructing the fractured orbit in all the 12 patients, and there was no infection, and titanium mesh loosening, prolapse, and rejection. With healthy eyes as controls, 11 cases of eyeball retraction were corrected completely, and only 1 case was still under correction. Diplopia symptoms disappeared in the 8 of 9 cases, and relieved in the 1 of 9 cases. Seven cases of eye movement limitation recovered postoperatively. To conclude, the individualized titanium mesh has great accuracy to repair orbital fractures in patients without serious complications,which has achieved good clinical outcomes in the orbital reconstruction.

BACKGROUND: Apical sealing ability is the key to ensure the long-term curative effect of root canal therapy. The post space preparation exposes some inevitable influence on root canal sealing ability, so how to minimize this effect becomes a hot spot.OBJECTIVE: To explore the effects of immediate or delayed post space preparation on the apical sealing ability of different root canal sealers.METHODS: Forty-eight extracted human premolar teeth were obtained, and the tooth crown was cut off. The samples were randomly divided into three groups (n=16 teeth per group). Group A underwent the immediate post space preparation; group B underwent the delayed post space preparation; group C without the post space preparation. Then all groups were subdivided into two groups, and then were filled with the gutta-percha/AH-Plus (groups A1, B1 and C 1)or the gutta-percha/mineral trioxide aggregate (groups A2, B2 and C2). The depth of apical dye penetration was measured using pressure-driven system. RESULTS AND CONCLUSION: There were no significant differences in the apical microleakage between groups A1 and B1, A2 and B2, C1 and C2 (P > 0.05). The apical microleakage in the group A1 was significantly higher than that in the group A2, and the group B1 also showed higher apical microleakage than the group B2 (P < 0.05). Our findings suggest that either immediate or delayed post space preparation exposes little influence on the apical microleakage after root canal filling with gutta-percha/mineral trioxide aggregate, which exhibits better apical sealing ability than the AH-plus.
