[์˜๋ฌธ]The success of dental implant therapy in esthetic aspect, relies mainly upon the presence and maintenance of the bone adjacent to the implant since the preservation of bone support is essential for the pink esthetics. Therefore, there have been many efforts to reduce the marginal bone loss by modifying the implant design, and microthread is one of them. The purpose of this study is to evaulate the long-term effect of microthread on the maintenance of marginal bone level. In this study, 17 patients were selected and two types of Astra Tech implants(Astra Tech AB, Molndal, Sweden) were used, one with microthread and one without it. In these patients, Astra Tech Single Tooth Implant(ATST) with microthread and Astra Tech TiOblast Implant(ATTB) without it were installed adjacent to each other within the same partially edentulous sites and marginal bone loss was evaluated by radiographic image. Using the level of marginal bone around the implant at the time of prosthesis insertion as reference, the change of bone level at 1-year, 2-year, and 3-year follow-ups were analyzed. 1. There was a statistically significant difference in the amount of annual marginal bone loss between ATST and ATTB(p<0.05).2. Marginal bone loss of ATST was stabilized after the first year, but ATTB reached a steady state after the second year. In couclusion, the microthread might be effective on maintaining and stabilizing the marginal bone loss against loading.ope
