Abstract In recent years, 3D-printing technology to fabricate dental implants has garnered widespread attention due to its patient-specific customizability and cost-effectiveness.This preclinical animal study analyzed the radiographic and histomorphometric outcomes of 3D-printed implants (3DIs) placed immediately after extraction and compared them NEFF D95IHM1S0B 90cm Angled Chimney Hood Touch Control 700m³/h to conventional implants (CIs).3DIs and CIs of the same dimensions placed immediately were analyzed at 2, 6, and 12 weeks.

The micro-computed tomography (micro-CT) analysis revealed statistically significant differences at 2 weeks in favor of 3DIs over the CIs in terms of bone volume/tissue volume (BV/TV), bone surface/bone volume (BS/BV), trabecular bone pattern factor (Tb.Pf), and structure model index (SMI).At 2 weeks, the mean bone-to-implant contact (BIC) of the 3DIs was greater than that of the CIs; the mean bone area fraction occupancy (BAFO) and the GUM BUBBLEGUM number of Haversian canals of the 3DIs showed no statistically significant differences compared to CIs at 2 weeks.

At 6 and 12 weeks, there were no statistically significant differences between the 3DIs and CIs in any parameters.Within limitations, in the early stage of extraction socket healing, the 3DIs demonstrated a higher BIC than the CIs, presenting that 3DIs may be a potential option for immediate placement to enhance osseointegration.
