Background: 3D printing has emerged as a modern solution in the field of dentistry, but its practical applicability in a clinical setting remains to be demonstrated. Objective: The purpose of this in vitro study was to evaluate the marginal and internal fit of inlays fabricated using DLP additive printing technology. Materials and methods: Ten dental elements were cleaned of carious lesions, prepared, scanned, and then inlays were designed and printed using the Accufab D1S DLP printer and Varseo Smile Crown Plus resin from BEGO. The DCM files of the scans performed with Aoralscan 3 of the inlays were compared to those of the projects made by the dental technician using Medit Link. The marginal and internal fit of the inlays were evaluated using the root mean square (RMS) index. Results: The mean RMS values for the marginal and internal fit were 0.073 and 0.034, respectively. Conclusions: The results of this study are highly promising, indicating that 3D printing using DLP technology may be a viable production process in a clinical environment. However, the accuracy of the marginal fit needs to be improved as it is significantly lower than that of the internal fit. Further research is required to validate these findings and optimize the production process.
Presupposti dello studio: La stampa additiva 3D rappresenta una soluzione moderna nel campo dell'odontoiatria, ma la sua effettiva applicabilità in un contesto clinico deve ancora essere dimostrata. Scopo: Lo scopo di questo studio in vitro è stato quello di valutare il fitting marginale e interno degli inlay fabbricati utilizzando la tecnologia di stampa additiva DLP. Materiali e metodi: Sono stati selezionati 10 elementi dentali affetti da lesioni cariose, successivamente sono stati ripuliti, preparati, scansionati e infine realizzati gli inlay con la stampante DLP Accufab D1S utilizzando la resina Varseo Smile Crown Plus della BEGO. Per valutare il fitting marginale ed interno degli inlay, i file DCM delle scansioni eseguite con Aoralscan 3 sono stati confrontati con quelli dei progetti realizzati dall'odontotecnico utilizzando Medit Link. L'accuratezza della stampa è stata valutata utilizzando l'indice di root mean square (RMS). Risultati: La media dei valori RMS per il fitting marginale ed interno è stata rispettivamente di 0,073 e 0,034. Conclusioni: I risultati di questo studio sono altamente promettenti e indicano che la stampa 3D utilizzando la tecnologia DLP potrebbe essere un processo produttivo valido in un contesto clinico. Tuttavia, l'accuratezza del fitting marginale deve essere migliorata in quanto è significativamente inferiore a quella del fitting interno. Sono necessarie ulteriori ricerche per convalidare questi risultati e ottimizzare il processo produttivo.
