The major challenge for dental implants is achieving optimal esthetic appearance and a concept to fulfill this criterion is evaluated.\r\nThe key to an esthetically pleasing appearance lies in the properly manage the soft tissue profile around dental implants. A novel\r\nimplant restoration technique on the surface was proposed as a way to augment both soft- and hard-tissue profiles at potential\r\nimplant sites. Different levels of roughness can be attained by sandblasting and acid etching, and a tetracalcium phosphate was\r\nused to supply the ions. In particular, the early stage attaching and repopulating abilities of bone cell osteoblasts (MC3T3-E1),\r\nfibroblasts (NIH 3T3), and epithelial cells (XB-2) were evaluated. The results showed that XB-2 cell adhesive qualities of a smooth\r\nsurface were better than those of the roughened surfaces, the proliferative properties were reversed. The effects of roughness on\r\nthe characteristics of 3T3 cells were opposite to the result for XB-2 cells. E1 proliferative ability did not differ with any statistical\r\nsignificance. These results suggest that a rougher surface which provided calcium and phosphate ions have the ability to enhance\r\nthe proliferation of osteoblast and the inhibition of fibroblast growth that enhance implant success ratios.
