Hallym University Sacred Heart Hospital proves the clinical effect of digital cement implants for the first time...Reduce treatment time by half and improve safety
Oct 29, 2025
Professor Park Sang-yoon and Yang Byung-eun of Hallym University Sacred Heart Hospital (Hospital Director Kim Hyung-soo) have demonstrated the clinical efficiency and safety of a digital cementless Screw-Retained Prosthetics (CL-SRP) that fixes prosthetics only with screws without using cement during implant procedures for the first time in Korea. The findings were published in the October issue of the Journal of Functional Biomaterials.
Most existing implant procedures attach prosthetics using cement, but safety controversy has continued because cement residues can cause inflammation or bone loss if they remain in the gums. To solve this problem, the research team conducted clinical trials on the CL-SRP system developed by applying a precision screw connection structure instead of cement and incorporating 3D digital design technology.
The study was conducted on 35 patients (40 single implants) at Hallym University Sacred Heart Hospital. As a result of comparing the existing mixed method (CSCRP) with CL-SRP, the total procedure time was reduced by 57% on average and the time to obtain impressions (tooth patterning) was reduced by less than half. The procedure accuracy and gum shape change remained the same as before, and the amount of bone absorption around the implant decreased by more than 30%, confirming long-term stability.
The study was conducted with the support of the Ministry of Trade, Industry and Energy's medical device commercialization project and the Korea Institute of Industrial Technology Evaluation and Management (KEIT). In particular, it is of great academic significance in that it is the first randomized controlled trial (RCT) for digital cementless implants in Korea. In particular, the risk of infection is low because there is no cement removal process, and the procedure is completed in a 'one-abutment-one-time' manner, greatly reducing patient discomfort.
Professor Park Sang-yoon "This study demonstrated that a cementless implant incorporating digital technology can improve both the efficiency and safety of the procedure."It will be a new alternative to reducing the risk of infection for patients and increasing the productivity of care for medical staff."
Professor Yang Byung-eun emphasized that "Digital implants without cement are a treatment paradigm that can realize patient-specific treatment and prognostic stability at the same time" and that "Digital dental care led by Hanlim University Sacred Heart Hospital will spread to the new standard."
