The current study introduces photocurable macromolecular resin (KIS resin) and aims to assess its use as a basic material for implant surgical stent fabrication using 3D printing and the digital light processing (DLP) technique. The biological and physical properties of KIS resin were evaluated, and radiological analysis was performed to assess the clinical accuracy of a 3D-printed surgical stent. The physical characteristics were analyzed in accordance with the guidelines of certified standards, and cell adhesion analysis was performed to evaluate the viability of human gingival fibroblast (hGF) cells exposed to KIS resin and conventional orthodontic acrylic resin. Radiological analysis of animals was carried out by pairwise overlap of pre- and postoperative images. The physical characteristics of KIS resin met the ISO 20795-1, ASTM D695, and ASTM D638 standards. The hGF cells on KIS resin samples exhibited better cell attachment and connection compared to those exposed to conventional resins. The findings of the radiological analyses showed statistically significant differences in the deviations between DLP-printed surgical stents and conventional stents, with the horizontal linear deviations being smaller in the coronal and middle levels of the former. Moreover, the angular deviation was also smaller in the DLP stent group. Therefore, KIS resin exhibited favorable physical properties and cell viability, highlighting its potential for use as a basic material for 3D-printed implant surgical guides. Further evaluation of the use of implant surgical stents fabricated using KIS resin and the DLP method as a proper tool for implant placement with clinical utility should be carried out.
