납착방법에 따른 임플란트 지지 보철물의 정확성 = The Accuracy of Implant Supported Prosthesis According to Soldering Method

다국어 초록 (Multilingual Abstract)

The Purpose of this study was to measure and compare the gap distance between implant fixture and implant framework fabricated by three techniques; (１) one-piece casting technique. (２) at the same time soldering technique after casting. (３) at the different time soldering technique after casting.
Four ３i (diameter ４.０ ㎜) implant fixtures were fixed in the stone block. Implant bar framework was completed with type １１１ gold alloys after it was waxed up with wax sleeve. Implant bar framework was soldered after it was cut with ０.２ ㎜ gap distance and fixed with pattern resin. Gap distances between each implant fixture and abutment, each gap distances were measured by means of stereomicroscope and micrometer ruler.
The results were as follows :
１. In comparison of gap distance between implant fixture and abutment, one-piece casting technique group was ５３１ ㎛, soldering at the same time group was ２５０ ㎛,soldering at the different time group was ４６ ㎛. Therefore, marginal adaptation of soldering technique group was higher than one-piece casting technique group. And marginal adaptation of soldering at the different time technique was higher than soldering at the same time technique.
２. In comparison of distance between abutment and abutment, one-piece casting technique group was ４４.１００ ㎜, soldering at the same time technique was ４４.０６４ ㎜, soldering at the different time was ４４.０５９ ㎜ and there were not significant differences.
