PURPOSE The aim of this study was to evaluate the influence of different 3D dental resins, using a manufacturer recommended printer and a third-party printer, on cellular responses of human gingival cells. MATERIALS AND METHODS Three NextDent resins (Denture 3D+, C&B MFH and Crowntec) were used to produce specimens on printers NextDent 5100 (groups ND, NC and NT, respectively) and Phrozen Sonic Mini 4K (groups PD, PC and PT, respectively). Human gingival fibroblasts were cultured and biocompatibility was evaluated on days 1, 3 and 7. IL-6 and IL-8 concentrations were evaluated at 3 days using ELISA. Surface roughness was evaluated by a contact profilometer. SEM and fluorescence micrographs were analyzed at days 1 and 7. Statistical analyses were performed using SPSS and mean differences were tested using ANOVA and post-hoc Tukey tests ( P < .05). RESULTS There was an increase in cellular viability after 7 days in groups PC and PT, when compared to group PD. ND group resulted in higher concentration of IL-6 when compared to PT group. SEM and fluorescence micrographs showed less adhesion and thinner morphology of fibroblasts from group PD. No significant differences were found regarding surface roughness. CONCLUSION The use of different printers or resins did not seem to influence surface roughness. NextDent 5100 and Phrozen Sonic Mini 4K produced resins with similar cellular responses in human gingival fibroblasts. However, Denture 3D+ resin resulted in significantly lower biocompatibility, when compared to C&B MFH and Crowntec resins. Further testing is required to support its long-term use, required for complete dentures.

The advent of computer-aided design and computer-aided manufacturing (CAD-CAM) technologies has revolutionized the fabrication of complete dentures [1]. Digital dentures provide numerous advantages, including saving patient data, shorter treatment times, better retention, improved mechanical properties, and simplified laboratory procedures [2][3][4][5][6]. The integration of CAD-CAM technology into denture fabrication has resulted in more precise and efficient fabrication processes, significantly transforming the field [7,8].In the relatively long history of CAD-CAM technologies in dentistry, the first attempt to fabricate digital complete dentures was reported in 1994 [9]. Currently, two main processes are used in the fabrication of digital complete dentures: (i) a subtractive approach that includes milling and grinding, and (ii) an additive manufacturing approach, often referred to as three-dimensional (3D) printing[10]. In the subtractive manufacturing process, the denture base is milled from a large pre-polymerized resin block. In general, artificial denture teeth are manually bonded to the denture base after milling [11,12]. Milled PMMA polymerized under high pressure and temperature exhibits excellent flexural properties, surface roughness, and hard-J Prosthodont Res. 2024; **(**): ****-****
