Background: Dental implantology is technique to replace missing teeth. Crestal bone loss along implant surface jeopardizes its longevity and success of treatment. The bone must remain healthy after dental implant is placed for the dental implant to last. However, the bone surrounding a dental implant is sometimes lost. There are several reasons for bone loss around a dental implant. In most cases, the bone loss starts at the top of the crest and progresses around the dental implant to form a saucer type defect. Materials and Methods: About 10 two-stage implants of life care implant system and 10 two-stage implants of Noble biocare implant system were placed in patients in fourth quadrant. Digital orthopantomograph (OPG) was taken on day of implant placement. After 6 months, at time of second stage surgery, the implant stability was evaluated by the periotest instrument. The crestal bone loss was evaluated on digital OPG. Same procedure for each system was carried out. Results: About 6 months after the implant placement, radiographic evaluation on digital OPG showed a mean crestal bone loss of 1.6 mm on the mesial side of implant and 1.8 mm on distal side of implant for Noble biocare system and radiographic evaluation on digital OPG showed a mean crestal bone loss of 0.7 mm on the mesial side of implant and 0.6 mm on distal side of implant for life care system. Conclusion: A study was conducted to evaluate crestal bone loss, occurring 6 months after implant placement in two implant systems, before loading it. More stress should be given on developing implant collar design to reduce the initial crestal bone loss. The smooth polished collar design of the implant may have contributed to crestal bone loss.
