简要总结
The effect of metal artifacts reduction protocols and tube potential difference on the metallic artifacts in cone beam computed tomography
详细描述
Our study is a quantitative as well as a qualitative assessment of the metal artifacts in the CBCT images in a bio models with multiple adjacent dental implants and single isolated implants , while using different MAR protocols inherited in the CBCT soft ware , as well as change in the tube potential difference of the CBCT unit

研究组 & 干预措施
Tube Potential difference
Different kVp values of the CBCT machine 70, 80 ,90 kVp
干预措施: CBCT radiation (Radiation)
MAR tool
MAR option in the software off and on
干预措施: CBCT radiation (Radiation)
结局指标
主要结局
Dental implant linear measurement
时间窗: 1 month
The implant length and width in millimeters will be assessed in the presence of the artifacts with and without the activation of the MAR tool of the CBCT soft ware, also change in the potential difference will be done with and without the activation of MAR tool
次要结局
- Bone- implant interphase(1 month)
