| 摘要 |
A dental implant (10) includes a screw body (12) and screw threads (14). The screw body (12) has an apical end (16) and a coronal end (18). Screw threads (14) include a primary thread (20) and a secondary thread (22), which overlap in at least a portion of the screw thread (14). Thread depth progressively increases from the coronal end (18) to the apical end (16). The coronal end (18) may contain any suitable secondary characteristics, such as machined threads, grooves, micro-threads, or any other characteristics favorable to successful outcomes with dental implant treatment. A method of making such the dental implant (10) is also disclosed. |
