Fabrication of Full-arch Implant Prostheses using a One-step Method for Recording the Jaw Relation

Fabrication of Full-arch Implant Prostheses using a One-step Method for Recording the Jaw Relation

In completely edentulous patients, reference points for determining the occlusal plane and vertical dimension are lacking. Therefore, accurately recording the jaw relation is essential for the fabrication of dentures or implant prostheses. Traditional methods using occlusal rims for bite registration require time for fabrication and intraoral adjustments, leading to patient discomfort with multiple visits. Recently, several methods have been developed to address these limitations by simultaneously obtaining impressions and jaw relation records. The JB Fork (PNUADD Co., Ltd., Busan, Korea) is a one-step jaw-relation recording system that can be integrated with digital protocols for fabrication of dental prostheses. It allows for simultaneous impression-making, verification of the maxillary anterior tooth arrangement, and recording of vertical and horizontal jaw relations, thereby facilitating the transfer of the occlusal plane. This case report aims to present a method for acquiring jaw-relation records using a JB fork and digital scan data.
