Influence of different zirconia surface treatments on biofilm formation in vitro and in situ.

ABSTRACT:

Objectives

To determine whether the surface treatment of zirconia affects biofilm formation in an in vitro three-species biofilm model and in situ.

Material and methods

Zirconia surfaces considered for the transmucosal portion of a zirconia implant were compared with polished pure titanium grade 4 (Tp). Disks 13 mm in diameter of either polished (Zp), polished and heat-treated (Zpt), machined (Zm), machined and heat-treated (Zmt) and sandblasted, etched and heat-treated (Z14) zirconia were fabricated. Surface roughness and wettability of specimens was measured. Biofilm formation was evaluated by safranin staining and scanning electron microscopy (SEM) using a three-species model, and intraorally with 16 volunteers carrying oral splints in two independent experiments.
