Abstract:Digital impressions have been studied for better gingival retraction in including the under subgingival finish line condition. Here, we employed swept-source optical coherence tomography (SS-OCT) of 1310 nm wavelength, which is capable of noninvasive, high-resolution, and high-speed, to discern the utilization-possibility for supporting the fabrication of the dental crown. A three-dimensional (3D) abutment was used at the 0.5 mm of the subgingival finish line below the level of the gingiva. The SS-OCT system s… Show more
“…Previous studies have reported that areas which cannot be visually assessed can be examined using OCT [13][14][15][16][17][18][19][20][21][22][23][24]. Others have also reported that nondestructive, noninvasive, and objective evaluations are possible using an OCT system [13][14][15][16][17][18][19][20][21][22][23][24]. In this study, internal cracks not seen on visual inspection were found; these cracks extended to the interior due to external impact (Figs.…”
