STATEMENT OF PROBLEM: Many dental clinicians are concerned about immediate loading of inserted implants. However, there have been few clinical studies surveying the success rates of immediate loading, based on Korean implant systems. PURPOSE: The aim of this study was to evaluate the outcome of immediate functional loading of the implant (SinusQuick(TM) EB, Neobiotech Co., Seoul, Korea) in partially edentulous maxilla or mandible. MATERIAL AND METHODS: Total 15 implants were placed. Within 2 weeks after implant insertion, provisional implant-supported fixed partial dentures were delivered to the patients. Quantitatively, marginal bone loss was measured at the time of immediate loading, after 3-months of continued loading and at the last follow-up. The mean follow-up period was 4.8 months. RESULTS: Mean marginal bone loss from implant surgery to early loading, 3-months follow-up and last follow-up was 0.03 +/- 0.07 mm, 0.16 +/- 0.17 mm and 0.29 +/- 0.19 mm. No implant failed up to 6 months after insertion, resulting in a 100% survival rate. CONCLUSION: Immediate loading exhibited high success rate in partial edentulism for up to 6 months. Well-controlled long term clinical studies with large sample size are necessary to confirm this finding.

  • Fig. 1 (A) Two implants (SinusQuick™ EB, Neobiotech Co., Seoul, Korea) were inserted at #36 and #37 area (black arrows). (B) Provsional restoration (white arrows) was delivered 14 days after implant placement.

  • Fig. 2 Periapical radiograph was taken at the time of (A) immediate loading and (B) 3-months after continued loading. The platform (black arrows) was a reference point to measure marginal bone loss. Provsional resin restoration was made by polymethylmethacrylate that is radiolucent. Therefore, only temporary cylinders are seen (white arrows).
