M a t e r i a l s a n d m e t h o d s Threemonthsafterextractionofallmandibularpremolarsandfirstmolars in six Labrador dogs, two implants, one with a novel turned surface (Combed) and a second with a moderately rough surface (ZirTi), were placedineachsideofthemandibleinthepremolarregionofeachdog.The 3-D parameters to express roughness and density of peaks were Sa = 1.399 μm and Sds = 0.065 μm2 forthe ZirTi surface and Sa = 0.600 μm and Sds = 0.314 μm2 for the Combed surface, respectively. Abutments were attached and the flaps were sutured to allow non- submerged healing. The animals were sacrificed after four months of healing, and ground sections were obtained for histomorphometric assessments of the hard-tissue integration. R e s u l t s All of the implants were osseointegrated. Mineralized bone-to-implant contact was 50.6 ± 18.3% and 56.3 ± 18.6%, while bone density was 54.6 ± 9.6% and 43.0 ± 9.0% at the Combed and ZirTi surfaces, respec- tively.Thedifferencebetweenthetwosurfaceswasstatisticallysignificant (p = 0.046) for both parameters evaluated. C o n c l u s i o n Implant surface characteristics influence the degree of osseointegration of implants placed in the alveolar process.
