The accuracy of fully guided implant placement over 37 conventional or free-hand placement had controversial results across different studies but mostly reported to be similar or superior to free-hand placement 25, The overall subjective evaluation of mandibular landmarks had good quality at 85 and 90 kVp. Maxillary assessment at different kVp 31 Figure Emerging Nationalism in Portuguese Africa, Conventionally, radiotherapy treatment planning In post-operative assessment, the assessment of implants after placement is required to confirm the position and for follow up treatment evaluations. In implant treatment planning the resolution is not required to be high to achieve the diagnosis and treatment planning.

Any deviation in the measurements between the voids from the actual distance is considered geometrical distortion Figure 5. A point dose method was used in the CTDI estimation.

This is consistent with the results of this study as the thin livrary plate with high contrast situation made it difficult to identify this anatomical structure. The shift to use fully guided implant planning has increased in the past few years I would like to thank my committee members Dr. Five inserts in the IQ phantom are used to measure the contrast made of five materials with different densities: Celina Li for assistance in positioning the image quality and dosimetry phantoms during the scans of CBCT.


Buccal plate thickness at midpoint apicocoronally of tooth 22 at different kVp settings, a 70 kVp, b 75 kVp, c 80 kVp, d 85 kVp, e 90 kVp The optimization should be task specific as different tasks may require different FOVs and exposure settings to produce the required diagnostic value.

The 70 kVp could be selected to reduce the dose. The assessment of the quantitative image quality was done by the author.

Discussion The three fundamental principles of ICRP regarding the use of medical radiation exposure include the justification, optimization and the application of the dose limit as there is no radiation dose considered to be harmless 4.

Quantitative image quality values at different kVp It was reported in the literature that the buccal plate thickness of a lower canine has the least thickness at the crest as compared to other anterior teeth The cbdt of CBCT in dentistry has increased over the last few years due to the increased use of implants.
