Periotest^ⓡ를 이용한 임프란트지지 보철물의 적합도 평가에 관한 연구 = An evaluation of precision fit of implant-supported prosthesis using the periotest^ⓡ

다국어 초록 (Multilingual Abstract)

In this study, the Periotest value was measured with Periotest?? to evaluate precision fit of the 2-unit and 3-unit implant-supported prosthesis by modifying the size and location of ill-fitted conditions. The 2-unit prosthesis was fabricated with the right implant fitted incorrectly and the 3-unit prosthesis with the right and center implant fitted incorrectly.
To evaluate the effects of the ill-fitted sizes, 4 groups were divided.: The control group being the accurately fabricated sample group fitted properly. Group 1 was constructed with 40㎛ ill-fitted conditions, group 2 with 70㎛ and group 3 with 100㎛ ill-fitted conditions.
The Periotest value was measured at each implant site after tightening 10Ncm.
The results was follows:
1. The PTV on the ill-fitted area in the 2-unit implant-supported prosthesis increased as the ill-fitted conditions increased. There was a statistically significant difference among groups (p<0.05).
In the same ill-fitted sample, the PTV depending on the measured location demonstrated a statistically significant difference (p<0.05).
2. The PTV on the ill-fitted area of the 3-unit implant-supported with an ill-fitted condition in the right implant increased as the ill-fitted conditions increased. There was a significant difference among groups (p<0.05).
In the same ill-fitted sample, the PTV depending on the measured location demonstrated a statistically significant difference (p<0.05).
3. In the 3-unit implant-supported prosthesis with ill fitting conditions in the center implant, the PTV on the ill-fitted area demonstrated a statistically significant difference between the control group, group 1 and group 2 (p<0.05).
In the same ill-fitted sample, the PTV depending on the measured location demonstrated significant difference between the gap side and the adjacent side with over 70㎛ ill-fitted conditions (p<0.05).
The results suggest that Periotest is a valuable objective method for evaluating the precision fit of an implant superstructure.
