Microscopical and chemical surface characterization of the gingival portion and connection of an internal hexagon abutment before and after different technical stages of preparation

Clinical Oral Implants Research, 05/17/2012

After technical procedures, presence of contaminants on the abutment surface in contact with the peri–implant tissues was confirmed. To prevent that such debris could interfere with biological stability of peri–implant tissues and, thus, enhance the implant–prosthesis integration, different cleaning protocols should be evaluated.
