The effect of non-submerged implant and immediate load technique on the early crestal bone loss around dental implants

Objective:To evaluate the clinical results of immediate loading to implants.Methods:A total of 49 ITI implants were placed in the mandibles or maxillae of 30 patients who required implant restoration.Thirty-two implants were used traditional implanted method and delayed loading,and 17 implants were immediately loaded with a provisional crown.The crestal bone loss around dental implants were measured at the day of implant and 1 week,1 month,3 month,6 month,12 month after implant.Results:There was no implant failure,and there was no significant difference in crestal bone loss around dental implants at all periods between traditional group and immediate load group.Discussion:Early implant theories thought that the osseointegration of implant must be completed under no load condition.However,further study showed that the load immediately imposed to implants can be used as a physiological stimulus to promote the bone tissue mineralization surrounding implant as long as the load was controled at a certain range.Conclusion:The application of non-submerged implant surgery and immediate load technique will not affect the crestal bone loss around dental implants,and it is an effective treatment option in implant dentistry.
