Abstract:
Purpose: The aim of the present study was to assess the marginal fit of interim restorations fabricated by 3D printing technique compared to conventional technique.
Methods: Typodont model of maxillary 1st molar was prepared for full coverage crowns. The prepared model was digitally scanned by 3D scanner. Duplication of master die into 20-epoxy resin dies. Interim crowns were constructed by two techniques: conventional chair side technology using a bis-acrylic based self-cure temporary material (structure-2- Voco, Germany) and 3D printing technology using (Next-dent C&B resin, Netherlands) material. The specimens were divided into 2 equal groups (n=10). Marginal adaptation was evaluated using stereomicroscope.
Results: The mean marginal gap value of 3D printing interim crowns (38.76±27.21 μm) was significantly lower than that of conventional chair-side crowns (120.43±32.63 μm).
Conclusion: Interim crowns fabricated by 3D printing showed superior marginal accuracy than conventionally constructed crowns.
