Depth of resin penetration into enamel with 3 types of enamel conditioning methods: A confocal microscopic study
Introduction The clinical efficiency of a bonding material relies on its bond strength and debonding characteristics; the depth of resin penetration into enamel affects both of these factors. The depth…
Comparison of deformation of 3 orthodontic miniplate lever arms
Introduction Deflections of the lever arms on 3 commercially available miniplates (Stryker, Kalamazoo, Mich; KLS Martin, Tuttlingen, Germany; and Synthes, West Chester, Pa) were compared to determine whether orthopedic forces…
Biodegradation of orthodontic metallic brackets and associated implications for friction
Introduction This study aimed to assess the effect of clinical exposure on the surface morphology, dimensions, and frictional behavior of metallic orthodontic brackets. Methods Ninety-five brackets, of 3 commercial brands,…
Registration accuracy in the integration of laser-scanned dental images into maxillofacial cone-beam computed tomography images
Introduction A precision 3-dimensional (3D) head model can be fabricated by integrating a digital dental model into a maxillofacial 3D image. The integration requires accurate registration of 2 image modalities….
