An Alumina Toughened Zirconia Composite for Dental Implant Application: In Vivo Animal Results

Figure 5

Representative histological images of cortical bone at 8 days. Note: E&E stain showing sporadic necrotic lacunae within cortical bone in proximity to the implant surface at 8 days (a) and healthy bone (b). This phenomenon occurred only at the earliest time point in a few cases for both alumina toughened zirconia and titanium implants and may be due the preparation of the implant site by drilling.
