Abstract
Aim: This study evaluated the precision and trueness of endodontic access guides fabricated using a cost-effective desktop LCD 3D
printer compared to a higher-cost SLA printer for guided endodontics.
Materials and methods: Thirty-two root canals from Nissin typodont teeth were divided into two groups: LCD and SLA. Virtual
planning was performed, and endodontic guides were fabricated using both 3D printing technologies. Pre-operative and postoperative
cone beam tomography (CBCT) scans were taken, and the linear deviation between the planned and actual access paths
was measured at two axial levels: the occlusal entry point and the canal orifice. Statistical analyses were conducted using independent
samples t-test at α = 0.05.
Results: At the occlusal entry point, the SLA printer demonstrated significantly higher accuracy with lower linear deviations
compared to the LCD printer (p < 0.05). However, at the canal orifice level, no significant difference in deviation was observed
between the two groups. Both 3D printing technologies successfully detected all root canals without perforations, showing
comparable precision at the orifice level.
Conclusion: Although the SLA printer exhibited better accuracy at the occlusal level, the cost-effective LCD printer provided
comparable results at the orifice level. These findings suggest that LCD 3D printers are a viable
