METHODS OF ALTERING BONE GROWTH BY ADMINISTRATION OF SOST OR WISE ANTAGONIST OR AGONIST
20230226086 · 2023-07-20 ·

The present invention provides a method of promoting local bone growth by administering a therapeutic amount of a Sost antagonist to a mammalian patient in need thereof. Preferably, the Sost antagonist is an antibody or FAB fragment selectively recognizing any one of SEQ ID NOS: 1-23. The Sost antagonist may be coadministered together or sequentially with a matrix conducive to anchoring new bone growth. Orthopedic and Periodontal devices comprising an implantable portion adapted to be permanently implanted within a mammalian body and bearing an external coating ofa Sost antagonist are also disclosed, as it a method ofincreasing bone density by administering to a mammalian patient a therapeutic amount ofa Sost antagonist together with an antiresorptive drug.

Dental pulp construct

Disclosed is a method for filling a root canal in a tooth. The method includes positioning a fiber in the root canal of the tooth, filling at least a portion of the root canal with an unset hydrogel composition, such that the unset hydrogel composition contacts at least a portion of the fiber, setting the hydrogel composition, thereby forming a set hydrogel, and removing the fiber from the set hydrogel, thereby leaving a channel in the set hydrogel. Methods and kits for repairing teeth are also described.
