Brief Summary:
The effect of metal artifacts reduction protocols and tube potential difference on the metallic artifacts in cone beam computed tomography

Condition or disease Intervention/treatment Phase
Metal Artifacts Radiation: CBCT radiation Not Applicable

Detailed Description:
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

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 2 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Investigator, Outcomes Assessor)
Primary Purpose: Diagnostic
Official Title: Effect of Metal Artifacts Reduction Protocols and Tube Potential Difference on Metal Artifacts in Cone Beam Computed
Actual Study Start Date : September 10, 2018
Actual Primary Completion Date : October 30, 2018
Estimated Study Completion Date : December 10, 2019

Arm Intervention/treatment
Experimental: Tube Potential difference
Different kVp values of the CBCT machine 70, 80 ,90 kVp
Radiation: CBCT radiation
CBCT scanning

Experimental: MAR tool
MAR option in the software off and on
Radiation: CBCT radiation
CBCT scanning

Primary Outcome Measures :
  1. Dental implant linear measurement [ Time Frame: 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

Secondary Outcome Measures :
  1. Bone- implant interphase [ Time Frame: 1 month ]
    Qualitative assessment if bone - implant interphase, will be either zero or 1 zero indicate that bone implant interphase cannot be assessed , one indicate that the bone implant interphase can be assessed
