Effect of implant surface properties on peri-implant bone healing: a histological and histomorphometric study in dogs

Abstract

The present study showed that SLActive(®) and NanoTite™ implants induce a similar bone response after implantation for 2, 4 and 8 weeks in a non-submerged position in the mandible of dogs.

Sandblasted and Acid-Etched Implant Surfaces With or Without High Surface Free Energy: Experimental and Clinical Background

“…Nevertheless, modSLA implants have also been directly compared to implants with different geometrical and surface chemistry designs. In comparison to calcium phosphate nanoparticlemodifi ed dual acid-etched (DCD/CaP) implants (Nanotite ® , 3i implant innovations, Biomet 3i, Palm Beach Gardens, USA), modSLA implants showed no signifi cant differences concerning BIC, fi rst BIC, and amount of bone volume after 2, 4, and 8 weeks of unloaded healing when inserted in canine mandibles with suffi cient native bone volume [ 157 ]; however, when the same types of implants were inserted in canines with buccal dehiscence-type defects that were created immediately following implant placement (compare above), modSLA implants revealed statistically signifi cantly increased amounts of new bone height and BIC after 2 and 8 weeks of unloaded healing in comparison to DCD/CaP implants [ 158 ]. In another study, Gottlow et al compared modSLA implants and titanium implants with an oxidized surface (TiUnite ® , Nobel Biocare AB, Gothenburg, Sweden; OX) in rabbits after 10 days and 3 and 6 weeks of integration.…”

Histological and Histomorphometric Evaluation of Zirconia Dental Implants Modified by Femtosecond Laser versus Titanium Implants: An Experimental Study in Fox Hound Dogs

“…The surface properties of zirconium dioxide (zirconia) make today impossible to produce the same textures as titanium implants by means of chemical and physical surface modifications. This is because zirconia is resistant to chemical treatment, especially acid attack, acid etching being a technique often used to treat titanium implant surfaces …”

Hard and soft tissue responses to three different implant materials in a dog model

“…Y-TZP also shows similar osseointegration as Ti implants 7,8) . Various modifications have been applied to experimental implants in order to improve the properties of zirconia implants for bone response, inflammatory response, biocompatibility and bacterial adherence [9][10][11][12] . Y-TZP has been compared with Ti in in vivo study and peri-implant bone response was not apparently different 13) .…”
