OBJECTIVES: The objective of this study was to evaluate bone formation/osseointegration following surgical treatment of experimental @entity737 at dental implants with different surface characteristics exposed to ligature induced breakdown conditions. METHODS: Ten turned (control), 10 sandblasted/acid etched (SA) and 10 SA/ @entity692 nano-coated (HA) implants were installed into the edentulated posterior mandible in five @entity235 and allowed to osseointegrate for 12 weeks. Ligature induced @entity154 were then induced over 23 weeks using stainless steel wire ligatures. The ligatures were removed and soft tissues allowed to heal for 3 weeks. Next, exposed implant surfaces were decontaminated followed by guided bone regeneration using a collagen membrane and submerged wound healing. The animals were euthanized for histometric analysis at 12 weeks postsurgery. RESULTS: The radiographic analysis showed vertical @entity604 following ligature induced breakdown without statistically significant differences among implant technologies. The histometric analysis showed significantly enhanced bone formation (height) at SA and SA/HA compared with turned implants (p = 0.028) following reconstructive surgery. Bone formation area was greater at SA/HA compared with turned implants, however the difference did not reach statistical significance. CONCLUSIONS: While ligature induced defect progression does not appear implant surface dependent in this animal model, bone formation at the decontaminated implant surfaces appears more favorable at SA and SA/HA over turned implants following reconstructive surgery.
