Abstract
To obtain a well formed soft tissue structure and inter-proximal papilla is challengeable work especially on anterior fixed prosthesis. In case of anterior region, transferring the information of well formed soft tissue which could be achieved by provisional restoration to the dental laboratory is important. In particular, the information of soft tissue around pontic area should be obtained with caution. It would be easily deformed when taking a final impression without support from provisional restoration, and the final prosthesis may not come out as intended by the clinician. Recently, the computer aided designed and manufactured (CAD / CAM) technique has widely spread, and an exact information of soft tissue around pontic could be transferred using CAD/CAM. In this case, a maxillary central incisors was extracted due to external root resorption and periodontal problem and the patients were treated an three-unit fixed dental prosthesis. Well formed soft tissue structure was obtained through provisional restoration, then, the exact information of soft tissue around pontic area was acquired without another appointment. The final prosthesis was successful in function and esthetics
