Abstract The surface roughness of the implanted titanium improves the attachment of implants to the bone and prevents undesirable cellular adhesion. The roughening of titanium surfaces is accomplished by using a continuous wave (CW) Nd: YAG laser. The characterization of surface topography and chemical composition was done by means of scanning electron microscopy and electron dispersive spectroscopy, X-ray diffraction, and surface roughness. The ability to generate precise topographies and increase Ti's roughness is obtained by using a laser. The most advantageous effects in terms of Ra (2.57nm) and Rz (2.96) for the roughness increase were observed, displaying better roughness values. Nd-YAG laser; in addition to strong thermal results, coniferous pulses reveal a sequence of irregular characteristics with dimensions within the order of tens of micrometers generated on the titanium surface. The quantity of the TiO phase will increase because of expanded heat input. The measured roughness increases with excessive laser power as an instantaneous end result of remelting. The usage of the appropriate continuous wave ND-YAG laser on the surface of titanium utilized in dental implants can increase osseointegration.
