Titanium implant functionalization with phosphate-containing polymers may favour in vivo osseointegration.

Aim: Osseointegration of titanium implants is predictable, but can be improved via surface functionalization.

Materials And Methods: One hundred and twenty implants were installed in parietal bone of 12 domestic pigs and left to heal for 1 or 3 months. Five groups were defined according surface treatments: immersion in water (H O), 10% polyphosphoric acid (PPA10), 1% phosphorylated pullulan (PPL1), 10% phosphorylated pullulan (PPL10) or 10% phosphorylated pullulan + 1 μg bone morphogenetic protein-2 (PPL10 BMP).

Dental Implant Macro-Design Features Can Impact the Dynamics of Osseointegration.

Purpose: The purpose of this study was to compare the clinical performance of two dental implant types possessing a different macro-design in the in vivo pig model.

Materials And Methods: Titanium Aadva(TM) implants (GC, Tokyo, Japan) were compared with OsseoSpeed(TM) implants (Astra, Mölndal, Sweden), with the Aadva implant displaying significant larger inter-thread dimensions than the OsseoSpeed implant. Implants were installed in the parietal bone of 12 domestic pigs and left for healing for either 1 or 3 months.
