Abstract
An implant for implantation into bone tissue includes an elongated body having an outer surface. The outer surface has at least one thread. The thread makes a number of turns around the body of the implant and includes a root, a flank and a crest. The root and a segment of the flank have a roughened portion compared to the crest. A method of forming an implant having a threaded outer surface including a root, a flank, and a crest includes treating the threaded outer surface at only the root and a portion of the flank while the crest remains untreated.
Claims20
A dental implant for implantation into bone tissue having an exterior surface comprising:
- an elongated body having an upper portion configured to receive a prosthesis, a lower portion for being submerged in said bone tissue, and an outer surface;
- and
- at least one thread on said outer surface making a plurality of turns around the elongated body between the lower portion and the upper portion, the at least one thread including a root, a flank, and a crest, wherein the root and a segment of the flank have a roughened portion relative to the crest, the roughened portion having a greater roughness as compared to the crest.
A dental implant for implantation into bone tissue, the implant having:
- at least one thread including a root, a flank, and a crest, the thread making a plurality of helical turns around the implant;
- and
- a roughened portion adjacent to the root of the thread, the roughened portion having a greater roughness as compared to the crest and helically extending along a length of the implant leaving the crest of the thread relatively smooth.
A method of forming a dental implant having a threaded outer surface including a root, a flank, and a crest, the method comprising:
- treating the threaded outer surface at only the root and a portion of the flank such that the crest remains untreated and the root and a portion of the flank having a greater roughness as compared to the crest.
