Introduction: Despite the increasing use of modern materials such as various alloys, composites, and ceramics, gold still plays an important role, especially in the fabrication of high-quality dental prostheses. One example of high-quality restorations with excellent stability and fit is the conical or telescopic supported complete denture, particularly with galvanically deposited gold secondary crowns. Conical crowns have a specific geometry, with the outer surfaces of the primary crowns shaped as a cone. The taper angle of the primary crowns usually ranges between 1° and 8°. Compared to telescopic crowns, which have parallel sides with a 0° angle, conical crowns are easier to insert because the taper provides additional manoeuvring space. Aim: The aim of this thesis is to examine the use of gold in laboratory dental prosthetics, its biocompatibility, as well as its advantages and limitations. The thesis also aims to present the double crown system, highlighting the differences between conical and telescopic crowns, with a particular focus on the fabrication of secondary crowns using the electrodeposition method, illustrated through the example of a conical-supported complete denture. Methods: The thesis employed both descriptive and experimental research methods. In the descriptive part, literature was collected from various websites and databases in Slovenian and English using relevant keywords. The experimental part was conducted in a dental laboratory, where double crowns for a conical-supported complete denture were fabricated using galvanization based on prosthetic knowledge and techniques. Results: The fabrication process of a conical-supported complete denture with galvanically deposited gold secondary crowns is presented using visual material according to chronological stages. Discussion and Conclusion: Dental prosthetics continuously evolve due to increasing patient demands, with gold maintaining an important role because of its biocompatibility, durability, and exceptional precision of galvanic double crowns. The example of a complete denture on conical crowns demonstrated stability, favourable occlusal force distribution, and aesthetic refinement. Therefore, gold will remain indispensable in complex prosthetic treatments where alternatives cannot provide the same level of quality, despite higher costs.
