    摘要: A bone fixture with various moduli has an implant body. The implant body includes a first implanting segment adapted to be implanted into a cortical bone of a bone and a second implanting segment adapted to be implanted into a cancellous bone of the bone and located below the first implant segment. A first young's modulus of the first implanting segment is smaller than a second young's modulus of the second implanting segment. Because the first young's modulus of the first implanting segment adapted to be implanted in the cortical bone is smaller than the second young's modulus of the second implanting segment adapted to be implanted in the cancellous bone, forces applied to the bone fixture can be evenly distributed to avoid the stress concentration at the cortical bone of the bone.

    摘要: The present disclosure provides a dental implant configured to be inserted in a hole in jaw bone and to be at least partially situated in the bone tissue when implanted and includes: a coronal region, an apical region, a longitudinal axis extending from the coronal region of the dental implant to the apical region of the dental implant; an implant surface configured to form an interface between an implant material and the oral environment/surrounding tissue and a surface layer formed on at least part of the implant surface, the surface layer including crystalline titanium oxide in the anatase phase and wherein the surface area roughness Sa and the pore size of the implant surface on which said surface layer is formed increase from the coronal region toward the apical region of the dental implant along the longitudinal axis.

    摘要: The present disclosure relates to a medical cement composition containing calcium silicate in an amount of less than 20 wt % of a total weight of the composition, with a lithium salt being added thereto. The medical cement composition of the present disclosure has a low compressive strength of 12 MPa or less, after being hardened, for easy removal, excellent stability in storage, and high bioactivity.

    摘要: A dental pulp capping composition can comprise a particulate base material which is non-toxic, and capable of forming a structural capping matrix; and a particulate setting material which is non-toxic, water-soluble, biocompatible, and capable of setting the composition. Optional growth factors can also be introduced into the composition to facilitate dental tissue repair. A complimentary method of restoring damaged tooth features can comprise removing diseased and/or damaged portions of the tooth to expose a prepared tooth region. Water can be added to the dental pulp capping composition to form a workable coherent paste. The workable coherent paste can be introduced into the prepared tooth region. The workable coherent paste can then be shaped within the prepared tooth region and then set to form a rigid biomimetic structure within the prepared tooth region.
