- Abstract
- Purpose: This study aimed to compare three-dimensional adaptation with the rinsing time ofthe temporary crown produced using the digital light processing method.
Methods: The maxillary right first molar abutment was scanned with a dental scanner. Atemporary crown was designed with the scanned abutment. The designed crown was madeof 10 temporary crowns using a digital light processing printer. The crowns were divided intothe 5-minute and 10-minute rinsing groups; 5 temporary crown washes were performed foreach group. In order to obtain the internal data, each group was scanned for a temporarycrown. The three-dimensional fit was measured by superimposing the scanned internal surfacedata and the abutment data. The average comparison of three-dimensional adaptationwas analyzed using the Mann–Whitney U test.
Results: The 5-minute rinsing group showed a significantly higher adaptation of 71.42±3.08μm as compared to the 10-minute rinsing group (67.52±0.92 μm) (p<0.05).
Conclusion: When making a temporary crown with a digital light processing method, a rinsingtime of 10 minutes is appropriate.
