The surface morphology of dental implants affects the primary stability (mechanical stability), the secondary stability (osseointegration), and the tertiary stability (long-term stability). In this work, the effects of surface etching on commercially pure titanium grade 4 (cp Ti G4) were investigated. The objective was to study the influence of temperature and time of acid etching on surface roughness and morphology. The roughness parameters were measured with 3D optical surface profilers and the surface morphology was analyzed by scanning electron microscopy. The results showed that the roughness parameters Ra, Rsk, Rz, Rms, peak size and valley depth increased as the temperature and time of etching increased. An empirical mathematical model was developed relating the etching variables to the roughness parameters. Based on this mathematical model, one may choose the optimum temperature and time of etching to obtain the best surface roughness parameters for osseointegration.
