Molinero-Mourelle, Pedro / Canals, Silvia / Gómez-Polo, Miguel / Solá-Ruiz, Ma Fernanda / Del Río Highsmith, Jaime / Viñuela, Alicia Celemín
Purpose: To assess the marginal fit of provisional polylactic acid (PLA) crowns obtained via three-dimensional (3D) printing using a profile projector.
Materials and Methods: A stone cast was scanned, and 15 provisional dental crowns were designed and printed in PLA using a 0.2-mm nozzle and 135-degree build angle. The marginal fit was measured at six points on each crown using a profile projector.
Results and Conclusion: Within the limitations of this study, the marginal fit of PLA provisional restorations was clinically acceptable, and the results were comparable to those observed with polymethyl methacrylate provisional restorations.
