  • Patent number: 5846079
    Abstract: A system for making anatomically correct and aesthetically pleasing dental restorations, including a modeling structure for fashioning a custom-made impression coping and a method of using the model to form said impression coping. A healing abutment used in second stage surgery to form an opening in the gingiva of a dental patient is attached to an implant analog within the model. Impression material is poured into the modeling receptacle around the healing abutment so as to form a model of the patient's gingival layer, including a cavity in the model corresponding to the opening in the patient's gingival layer. A narrow coping shaft is attached to the implant analog within the modeling receptacle, and a modeling material is poured into the cavity and allowed to harden around the narrow coping shaft, thus forming an impression coping with a transmucosal section replicating the size and shape of the healing abutment.
