Progress and developmennt of reacent dental implant were observed remarkably during last twe to three decade years introducing two step technic with root form implant to get good osseointegration. The survival rate of each implant system was around 90% even though limited systems only showed the long term results of implant survival and cervical born resorption around implant.The porpose of this study is to develop the cinical indication and improve its success late using newly developeant porous-coated implant. This study was carried out keeping international cooperation amoung three resarch institute groopes, namely this study group, surported by Grant-in-Aid for Scientific Research・JAPAN (Nihon University), Prof.D.A.Deporter'group (University of Toronto, CANADA) and Dr.D.S.Sohn'grope (Taege Hyosung Catholic University Hospital, KOREA).Following results were obtained.(1) A number of follow up clinical study of porous-coated implant (ENDO-PORE IMPLANT) increased up to 240 cases.(2) As prof.Deperter proporsed new technic "Simplefying Management of the Posterior Max illa Using Shot, Porous-Surfaced Dental Implants and Stimultaneous Indirect Sinus Elevation", head investgater Dr.T.Saito carried out the interpreatation of the paper, and printed it on PRO-Japanese Edition (July, 2000. Quintessence Japan)(3) As prof.N.Meredith reported new prognostic for initial stability of implant, titled "Assesment of Implant Stability as Prognostic Determination" (International J.Prothodont. 1998.5.), head investgater Dr.T.Saito carried out the interpreatation of the paper, and sent it for print on I.J.Implant japanese edition (May, 2001. Quintessence Japan)(4) Head Investgater Dr.T.Saito visited to Taegu Catholic Hospital with two cooparator and discussed present problems such as a new thechnic of implantation immediate after tooth extraction and or imediate loading after implantation.

在过去的二十至三十年里，新牙种植体的进步和发展得到了显着的观察，引入了根形种植体的两步技术以获得良好的骨整合。尽管有限的系统仅显示植入物存活和植入物周围宫颈天生吸收的长期结果，但每个植入物系统的存活率约为90％。本研究的目的是使用新开发的多孔涂层植入物开发临床适应症并提高其后期成功率。本研究是在日本科学研究补助金（日本大学）、Prof.D.A.Deporter'group（多伦多大学，加拿大）和Dr.D.S.Sohn'grope（韩国太极晓星天主教大学医院）的资助下，由三个研究机构组（即本研究组）保持国际合作进行的。获得了以下结果。（1）多项后续临床研究 多孔涂层种植体（ENDO-PORE IMPLANT）的数量增加到240例。（2）Deperter教授提出新技术“Simplefying Management of the Poterior Max illa Using Shot, Porous-Surfaced Dental Implants and Stimultaneous Indirect Sinus Elevation”，首席研究员Dr.T.Saito对该论文进行了解读，并打印在PRO-日文版上（2000 年 7 月。 Quintessence Japan)(3) N.Meredith 教授报告了种植体初始稳定性的新预后，题为“Assesment of Implant Stability as Prognostic Decisionation”（International J.Prothodont. 1998.5.），首席研究员 Dr.T.Saito 对该论文进行了解释，并在 I.J.Implant 日文版上印刷（2001 年 5 月）。日本精髓）(4) 头 Investgater T.Saito博士与两位合作者一起访问了大邱天主教医院，并讨论了拔牙后立即种植的新技术和/或种植后立即负重等当前的问题。
