研究室紹介
Professor Sori Kim's research lab specializes in digital dentistry and prosthetic restorations, focusing on the precision, accuracy, and biocompatibility of CAD/CAM-fabricated dental prostheses. The lab investigates critical factors influencing the clinical performance of dental crowns and bridges, including material bonding strength, machining parameters, and three-dimensional fit. Research spans from material science—such as non-precious alloy and porcelain bonding—to advanced digital workflows involving 3D scanning, CAD design, and CNC milling. The lab emphasizes evidence-based optimization of dental prosthetic fabrication to enhance long-term clinical outcomes.

3Purpose: This study aimed to investigate the shear bond strength for non-precious alloy castings without beryllium, which has been used repeatedly for economical reason. Methods: The Schmitz-Schulmeyer test method was used to evaluate the shear bond strength between the nonberyllium Ni-Cr alloy Vera Bond 2V(AlbaDent, Inc. USA) and the Ceramco 3(Dentstply, York, PA, USA) porcelain powder. The maximum loading and shear bond strength were measured. The average shear strength( ) was analyzed with th
Purpose: The purpose of this paper was to evaluate the occurrence of errors regarding adaptation by conducting a three-dimensional assessment comparing the bridge type dental restoration after the cutting process, which has multiple abutments, with a single type dental restoration. Methods: By using ten identical files obtained by scanning the master model, thirty designs were created consisting of ten maxillary right first premolars and ten maxillary right first molars with single crown abutmen
Purpose: The purpose of this study is to evaluate the trueness and fitness of machined prostheses according to drill radius setting in CAD software. Methods: For this study, standard abutment were replicated in Type Ⅳ stone. The stone abutment were scanned using a dental scanner. The CAD design software was designed using scanned abutment data. When designing, the drill radius was set to 0.3 mm and 0 mm, respectively, and saved. The saved design data was milled using a milling machine (n=13). Th
