Abstract ▼ AI-Helper

Statement of problem. Reducing treatment time in implant dentistry is a matter of main concern. There are so many factors affecting the success rate of immediate or early loaded implant for the initial bone response. The especially microscopic properties of implant surfaces playa major role in the osseous healing of dental implant. Purpose. The aims of this study were to perform a histologic and histomorphometric comparison of the healing characteristics anodically roughened surface, HA coated surface and RBM surface implant, and to compare of ISQ values measured by $Osstell^{TM}$ for resonance frequency analysis in dogs mandible during 2 weeks. Material and method. Bone blocks from 2 dogs were caught after covered healing for 0 day(2 h); Group I, 1 week; Group II and 2 weeks; Group III. One longitudinal section was obtained for each implant and stained with hematoxylin and eosin. Histomorphometric analysis was done with Kappa Imagebase system to calculate bone-to-implant contact and bone volumes inside the threads. ISQ values were measured in every time of surgery schedule. Conclusion. The experiment revealed that: 1. The percentages of bone-to-implant contact on the fixture in each group were not significantly different(P > 0.05). 2. The percentages of bone area inside the threads on the fixture in each group were not significantly different(P > 0.05). 3. The ISQ level showed clinical stability of each fixture during 2 weeks(all ISQ level ${\geq}71$ ).

제안 방법

The aims of this study were to perform a his tologic and histomorphometric comparison of the healing characteristics of anodically roughened surface (TiUnitez Nobel Biocare, Gtiteborg, Sweden), HA coated surface (Replace select, Nobel Biocare, GtJteborg/ Sweden) and RBM surface (Kimplant Avana®, Osstem, Busan, Korea), and to compare of ISQ values measured by Osstell™ for reso nance frequency analysis in dogs mandible dur ing 2 weeks.

대상 데이터

I) Each transducer is calibrated by the manufacturer, which makes all measurements directly compa rable. In this study, transducer “Type F13 L5;100132, ' for Replace select and “ Type Fl L 8.5; 10050', for external hexagon(Kimplant and TiUnite) were used.
The partially extracted mandibles were prepared for the sites of fixtures and washed and decontaminated with Betadine (Sung Kwang, Buchunz South Korea) and prior to surgical draping. One milliliter of 2% lidocaine (Yu-han; 1:100, 000) was administered local to the implant sites.

데이터처리

In calculation bone volumes inside threads, polygonal tool of system was used, which con nected the boundary line of bone, vacant space, and threads. And then the ratio was calculated by Microsoft Excel.
Mean values of bone contact ratio and bone area in each group were calculated and subjected to a repeated measure ANOVA to test for signifi cant differences. Statistical testing was carried out at the 5% significance level.

성능/효과

1. The percentages of bone-to-implant contact on the fixture in each group were not signifi cantly different(P > 0.05).
2. The percentages of bone area inside threads on the fixture in each group were not signifi cantly different(P > 0.05).
3. The ISQ level measured by OsstellTM showed clinical stability of each fixture during 2 weeks (all ISQ lev이 >71).
In this study, no significant difference was found from histomorphometric analysis between Kimplant and other commercially available implants. In conclusion Kimplant were devel oped successfully in comparison with the results of commercially used TiUnite and Replace Select in 2 weeks study.
