The aim of this study was to compare and analyze the survival rate, success rate, and loss of marginal bone of internal and external hexes and presence or absence of microthreads of implant immediately installed after tooth extraction. Forty-four implants were installed in 30 patients, average follow-up period was 80 months, and each product was divided into 3 groups. Group 1 is Osstem TS III implant, Group 2 is Osstem US II implant, and Group 3 is Implantium implant. Panoramic and periapical radiographs were used to measure the marginal bone loss. One implant was removed during the study period, and TS III had a survival rate of 100% and a success rate of 88%, US II had a survival rate of 100% and a success rate of 100%, Implantium had a survival rate of 95% and a success rate of 89%. These results suggest that Osstem and Dentium products show good clinical prognosis when implant is immediately installed after extraction, so it may be a good treatment option in the case of indications.
