Bcp® Surface Treatment
Implants were placed in the femurs of miniature pigs. After 3 and 6 weeks respectively, the implants were removed and analyzed. Signifi cant differences were noted in the percentage of B.I.C. (Bone Implant Contact). Polished, sandblasted with fi ne grit, or acid etched implant surfaces had the lowest percentage of B.I.C. (B.I.C. < 25%). Grit-blasted (coarse grit) or T.P.S. (Titanium Plasma Spra...
متن کاملPhotodynamic treatment for surface sanitation
The bactericidal effect of visible light illumination on bacteria treated with non-toxic photosensitizers (PS) has been shown previously, its effectiveness depended on both cell type and nature of photosensitizer used. The photosensitizer (PS)-mediated bactericidal effect of light against different types of microorganisms including vegetative bacteria (both in planktonic form and in biofilms), ...

For centuries, clinicians have been attempting to replace missing teeth with suitable synthetic materials. Dental implants are fixtures that serve as replacements for the root of the missing natural tooth and becoming popular in the current day dental practice. Success or failure of the dental implant treatment is mainly based on the principles of creating and maintaining an interface between t...
متن کاملEffect of surface treatment on enamel surface roughness
PURPOSE To compare the effects of different methods of surface treatment on enamel roughness. MATERIALS AND METHODS Ninety human maxillary first premolars were randomly divided into three groups (n=30) according to type of enamel surface treatment: I, acid etching; II, Er:YAG laser; III, Nd:YAG laser. The surface roughness of enamel was measured with a noncontact optical profilometer. For eac...
