초록

본 연구는 상악동골이식술에 사용된 다양한 골이식재와 자가치아골이식재의 효율성을 비교하고 조직형태계측학적으로 평가하는 것이다. 2007년 10월부터 2009년 9월까지 분당서울대학교병원에서 상악동골이식술을 시행 받은 24명의 환자들을 대상으로 하였다. 환자들의 평균 나이는 $52.51{\pm}11.86$세였다. 모든 증례들은 사용된 골이식재의 종류에 따라 3그룹으로 분류되었다. 1군: 자가치아골이식재, 2군: OrthoblastII(integra lifescience corp. Irvine, US)+Biocera(Osscotec, seoul, korea), 3군: DBX(Synthes, USA)+BioOss(Geistlich Pharm AG, Wolhusen, Switzerland). 총 37개의 임프란트가 식립되었다(1군: 7, 2군: 10, 3군: 20). 신생골 형성, 직골과 층판골의 비율, 신생골과 골이식재의 비율을 조직형태계측학적으로 평가하였다. 통계처리는 SPSS Ver. 12.0을 사용하여 Kruskal-Wallis test를 시행하였다. 신생골 형성 비율은 1군 $52.5{\pm}10.7$, 2군 $52.0{\pm}23.4$, 3군 $51.0{\pm}18.3$였고 통계적으로 유의성 있는 차이는 없었다. 직골과 층판골의 비율은 1군 $82.8{\pm}15.3$, 2군 $36.7{\pm}59.3$, 3군 $31.0{\pm}51.2$였다. 신생골과 잔존골이식재의 비율은 1군 $81.3{\pm}10.4$, 2군 $72.5{\pm}28.8$, 3군 $80.3{\pm}24.0$였다. 4개월의 치유기간 후에 모든 군에서 양호한 신생골 형성이 이루어졌다. 본 연구의 제한적인 범위 내에서 자가치아골이식재는 상악동골이식에 사용될 수 있는 새로운 골이식재료라고 사료된다.

The aim of this study was to evaluate histomorphometrically and compare the efficiency of various bone graft material and autogenous tooth bone graft material which were used in sinus bone graft procedure. Subjects were the 24 patients who had treated with sinus bone graft using lateral approach from October 2007 to September 2009 at SNUBH. The average age was $52.51{\pm}11.86$ years. All cases was taken after 4month of procedure and divided into 3 groups according to bone graft material. Group 1: autogenous tooth bone graft material, Group 2: OrthoblastII(integra lifescience corp. Irvine, US)+Biocera(Osscotec, seoul, korea), group 3: DBX(Synthes, USA)+BioOss(Geistlich Pharm AG, Wolhusen, Switzerland). Total 37 implant placement area were included and evaluated(7 in group 1, 10 in group 2, 20 in group 3). Evaluation of new bone formation, ratio of woven bone to lamellar bone, ratio of new bone to graft material were performed on each tissue section. Kruskal-Wallis test was used for statistical analysis(SPSS Ver. 12.0, USA). New bone formation were $52.5{\pm}10.7%$ in group 1, $52.0{\pm}23.4%$ in group 2, $51.0{\pm}18.3%$ in group 3. There were no statistical significant differences between each groups. Ratio of woven bone to lamella bone were $82.8{\pm}15.3%$ in group 1, $36.7{\pm}59.3%$ in group 2, $31.0{\pm} 51.2%$ in group 3. Ratio of new bone to graft material were $81.3{\pm}10.4%$ in group 1, $72.5{\pm}28.8%$ in group 2, $80.3{\pm}24.0%$ in group 3. After 4 month of healing period, all group showed favorable new bone formation and around graft material and implant. Within limitation of our study, it is suggested that autogenous tooth bone graft material might be used as novel bone graft material for sinus bone graft.
