Abstract:
Objective:To compare the changes of marginal bone resportion between immediate implantation and delayed implantation after 12 to 24 months of definitive prostheses finished.Methods:41 patients were recruited and divided into immediate implant placement group(n =20) and delayed implant placement group(n =21).All implants were evaluated via radiograph after surgery,6 months after implantion,1 year and 2 years after prostheses placement respectively,the height of marginal bone was measured 6 month after implation,1 year and 2 years after prostheses placement.Results:After 6 month,1 year and 2 year the mesial marginal bone attachement (MBA) of immediate implant placement group increased by (1.35 ± 1.12),(2.16 ± 1.73) and (2.53 ± 1.65) mm,the distal by (1.46 ± 1.17),(1.94 ± 1.16) and (2.32 ± 1.68) mm,respectively (among the 3 time points of examination,P ＜ 0.05).As for the delayed implantation group,in the mesial area MBA increased by (-0.52 ± 0.47),(-0.69 ± 0.58) and (-0.97 ± 0.78) mm,in the distal area by (-0.46 ± 0.44),(-0.60 ± 0.45) and (-0.72 ± 0.63) mm (among 3 time points,P ＞ 0.05).Conclusion:Immediate implantation is superior to delayed implantation for marginal bone attachement of dental implant.
