Three types of mandibular bone resorption and their re- spective bone augmentation techniques for successful dental implant treatments DrKeiichiNaruse With reference to older and the latest research, particularly Naruse et al., I share my opinions and ex- perience on bone augmentation techniques accord- ing to the condition of the bone or degree of bone re- sorption. Bone augmentation in patients with resorbed mandibular ridges due to severe periodontal disease requires the use of advanced techniques. Mandibular bone resorption and the respective bone augmenta- tion techniques are divided into three types based on the condition of severely and vertically resorbed mandibular ridges. One bone augmentation tech- nique entails using non-autogenous bone. I agree with other researchers that autogenous bone, owing to its osteogenic, osteoinductive and osteoconduc- tiveabilities,ispreferredasabonereplacementmate- rial in bone augmentation. However, I am also aware thatthisinvasivetechniquemaycausesubsequentin- fection in the donor site. Therefore, in order to per- form minimally invasive surgery, I performed 15 mm bone augmentation without using autogenous bone and the case was successful. Reference K.

Effect of metal artefacts on the visualization of periim- plant anatomy in cone-beam computed and volumetric tomography images DrShoheiIkeda The objective of this study was to assess the effect of metal artefacts on the confidence levels of ob- serversintheanalysisofcross-sectionalperi-implant anatomy in the buccolingual plane using CBCT and volumetric tomography (VT). The VT machine used was OP200 D (Instrumen- tarium Dental) and the CBCT machine was 3DX (Morita). ITI implants (Straumann; Ø 3.8 mm, L 15 mm) were used.
