Definitions

  • Figure IB is a side view of the dental implant of Figure IA.
  • Calcium phosphate ceramics such as tricalcium phosphate (TCP) and hydroxyapatite (HA) are examples of materials that can enhance osseointegration by changing the chemistry of the outer surface 40.
  • the outer surface 40 can comprise macroscopic structures, such as, for example, threads, micro-threads, indentations, and/or grooves that are configured to promote osseointegration and can be used alone or combined with the roughening and/or the coatings described above.
  • the outer surface 40 comprises a microstructure surface, such as a highly crystalline and phosphate enriched titanium oxide microstructured surface with open pores in the low micrometer range. An example of such a surface is sold under the trademark TiUniteTM by Nobel Biocare AB.
  • the depth of the thread 38 in the central portion 27 is between about 0.1 mm to about 0.5 mm, or between about 0.2 mm to about 0.4 mm, or about 0.3 mm. In some embodiments, the thread 38 pitch is between about 0.4 mm to about 1.0 mm, or between about 0.6 mm to about 0.8 mm, or about 0.7 mm.
  • the coronal flank 56 extends substantially perpendicularly from the longitudinal axis of implant 20. In some embodiments, the coronal flank 56 extends at an angle between about 45 degrees to about 90 degrees, or between about 60 degrees to about 90 degrees, or between about 75 degrees to about 90 degrees from the longitudinal axis of the implant 20. In some embodiments, the apical flank 54 is oriented at an angle between about 15 degrees to about 45 degrees, or between about 25 degrees to about 35 degrees, or about 30 degrees with respect to the coronal flank 56.
  • the peaks 84 can be located closer to either the buccal valley 86 or the lingual valley 87.
  • This configuration of the top edge 82 and the peaks 84 and valleys 86 and 87 result in an asymmetrical dental implant 20 that is well suited for matching asymmetrical bone-tissue morphologies, resulting in an aesthetically pleasing dental implant 20.
  • the peaks 84 and valleys 86 and 87 may have different heights. That is, the two peaks 84 may have different heights as compared to each other.
  • the two valleys 86 and 87 may have different heights as compared to each other, as described above for example. In this manner, the implant 10 can be placed in situations where the bone ridge has an asymmetrical shape with the buccal side being typically lower.
  • abutment 100 has been illustrated with a generally hexagonal interlock portion 106
  • suitable shapes may also be used.
  • Such alternative suitable shapes may comprise other shapes configured to mate with interlock recess 74 and to prevent rotation of the abutment 100.
  • FIGS. 5 A and 5B illustrate an embodiment of an abutment 100 that is configured to mate with the embodiment of the dental implant 20 illustrated in FIGS. 4A and 4B.
  • This embodiment of the abutment 100 is similar to the embodiments described above.
  • a different variation of an interlock portion 106 is shown.
  • the interlock portion is hexagonal.
