Article Synopsis
- * Materials and Methods: Twelve Ti and twelve Zr implants were placed in human mandibles with half simulated for bone graft loss. CBCT images were taken with varied MAR settings, and five evaluators assessed graft loss using a scoring system.
- * Results: Using MAR on the OP300 unit improved diagnostic accuracy for both implant types, while extreme MAR mode on the Eagle 3D unit decreased accuracy. Overall, Ti implants showed higher diagnostic values than Zr implants.
Objectives: To investigate artefacts produced by different orthodontic brackets and wires in cone-beam computed tomography (CBCT) scans.
Materials And Methods: Two dental arches were made using extracted human teeth and plaster. Three pairs of acetate plates containing different brackets - metallic, ceramic, and self-ligating ceramic with NiTi clip - along with a control plate (i.
Objective: To investigate the association of perforation of the maxillary sinus floor by dental implants with mucosal thickening and to describe its characteristics in perforated cases.
Study Design: One-hundred and twenty-nine maxillary sinuses of 93 patients presenting 202 dental implants in the maxillary posterior region were retrospectively assessed in cone-beam computed tomography scans and classified according to maxillary sinus perforation, bone graft, mucosal thickening, and mucosal appearance. Logistic regression determined the chance of mucosal thickening in perforated maxillary sinuses.

Objective: The objective of this study was to evaluate the effects of spatial resolution and the application of enhancement filters in the diagnosis of simulated furcation defects and image quality with intraoral radiographs.
Study Design: Periapical images were acquired with photostimulable phosphor plates of molars in dry skulls (n = 8) and mandibles (n = 10) with 4 stages of furcation defect simulation. The plates were scanned in fast scan and high resolution modes to produce different spatial resolutions.
