Surface micro‐structuring of zirconia dental implants

Abstract

Sandblasting with 105-μm alumina followed by 1 h HF etching at room temperature and 1 h heat treatment at 1250°C is a reliable and tolerant process to create a surface roughness of about Ra = 1.2 μm on zirconia implants.

Evaluation of a one‐piece ceramic implant used for single‐tooth replacement and three‐unit fixed partial dentures: a prospective cohort clinical trial

“…To create a rough endosseous surface, the implants were sandblasted with alumina, etched with 38–40% HF, and finally heat‐treated at 1250 °C for 1 h to reduce the monoclinic fraction (Fischer et al. ). The process generates a mean average roughness ( R a ) of 1.2 μm.…”

Guided bone regeneration at zirconia and titanium dental implants: a pilot histological investigation

“…The obtained surface roughness was in the range of Ra = 1.2 μm (Fischer et al. ). Titanium bone level implant was used as control (OsseoSpeed™ S, ASTRA TECH Implant System, DENTSPLY Implants, Mannheim, Germany).…”
