The Influence of Surface Treatment on Osseointegration of Endosteal Implants Presenting Decompressing Vertical Chambers: An In Vivo Study in Sheep.

Purpose: To qualitatively and quantitatively evaluate histologic osseointegration parameters of implants designed with decompressing vertical chambers between the threads with two different surface treatments (TiO blasting + maleic acid vs TiO blasting + maleic + HCl) in a large translational animal model at 3 and 6 weeks in vivo.

Materials And Methods: Nine female sheep were used, and 72 implants with trapezoidal threads and decompressing vertical chambers of 0.6 mm in diameter and 0.

Effect of supplemental acid-etching on the early stages of osseointegration: A preclinical model.

Purpose: To evaluate the effect of two surface modifications on early osseointegration parameters of conical implants in a translational pre-clinical model.

Materials And Methods: Conical implants with progressive trapezoidal threads and healing chambers were evaluated consisting of two different surface conditions: 1) Implacil surface (IMP Sur), and 2) Implacil surface + Supplemental Acid-etching (IMP Sur + AE). Surface characterization comprised of the evaluation of roughness parameters (S, S and S), surface energy and contact angle.
