The main objective of impressions for fixed dental prostheses is to displace the gingival tissue and register the finish lines and prepared abutments accurately. To acquire preventive therapeutic, and aesthetic properties, the margins of restoration are accurately positioned in the prepared finish line of the abutment. In tooth-supported and implant-supported fixed prostheses, impression making requires an accurate record of the prepared finish line area, particularly where the finish line is located at the same level as gingiva or sub-gingiva. The Gingival retraction can cause tissue injury, bleeding, apical recession when proper positioning and minimal force application are not followed. Ideally, the retraction technique choice must be simple, quick, and inexpensive and should not cause damage to periodontal tissues. This article is an attempt to present the technique that involves the fabrication of a customized gingival cuff for abutment tooth by 3D printing technology using thermoplastic polyurethane material. Aim: The primary goal of this technique is to reversibly displace the gingival tissues such that an adequate amount of low viscosity impression material can be introduced into the widened sulcus and records the marginal detail. Result: The customized 3D printed gingival cuff was packed into the gingival sulcus using a cord packer facilitated easy gingival retraction without damaging the surrounding gingival tissue. Conclusion: This technique greatly reduces the marginal discrepancy of the final restoration with minimal trauma to the gingival tissues and achieve a desirable emergence profile of the restoration especially when the finish line is at, or just within, the gingival sulcus&#13;
