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.

Dental implant

Expandable fixation assemblies, expandable cranial fixation assemblies, and expandable intervertebral implant assemblies are provided for securing structures to bone and for securing bones and/or bone segments with respect to each other. An expansion member can be moved through at least a portion of an expandable fixation body, thereby causing expansion of the expandable fixation body, such that bone engagement features of the expandable fixation body engage surrounding structure, such as bone.

Expandable fixation assemblies

A locking member for a bone fixation device can include a locking body that defines an outer surface, an opposed bone contacting surface, and a slot that extends from the bone contacting surface to the outer surface. The locking member can further include at least one locking tooth that extends into the slot and a biasing member that extends into the slot and defines an abutment surface that faces the at least one locking tooth. The slot can be configured to receive a toothed member along an insertion direction and the biasing member can be configured to bias the toothed member toward the at least one locking tooth such that at least one tooth of the toothed member engages the at least one locking tooth of the locking member so as to prevent the toothed member from translating through the slot along a direction that is opposite the insertion direction.
