Oral implants and related methods, systems, and apparatus. Some embodiments may comprise a silicon nitride bone anchor configured to be integrated with and affixed to alveolar bone of a patients oral bone cavity. The bone anchor may comprise a core and an outer layer comprising a silicon nitride ceramic material. The outer layer may have a density less than a density of the core. An anchor abutment may be coupled with the bone anchor, and may be configured to protrude above epithelial tissue of the patients oral cavity and provide a substrate for positioning and fixation of a dental component, such as a crown or bridge.
