_Patient-specific restorations are the focus of state-of-the-art dentistry. A treatment concept tailored to the specific situation has also become indispensable in implant dentistry. Based on the case presented, this article describes how a cus- tom abutment can be used to create an implant- supported crown very similar to the natural tooth in shape and soft-tissue profile. A leading-edge treatment protocol distinguishes itself by a perfectly coordinated surgical-prosthetic procedure with the goal of harmony and long-term stability of peri-implant bone and keratinized mu- cosa. The key parameters of the concept are implant positioning in the lingual or palatal third of the alveolar ridge to ensure a buccal bone plate with aminimumthicknessof1.5mm.1,2 Inaddition,azone I case report _ dental implantology Fig. 1_The radiograph (OPG) of the initial situation.
