The fabrication of straight and angulated, custom, potentially modifiable abutments; straight, custom, potentially modifiable open tray impression posts; and straight and angulated, custom, potentially modifiable closed tray impression posts is provided. The custom abutments achieve the development of a three dimensionally customized gingival emergence profile according to the needs of each clinical case in different sizes and dimensions around the implant platform. Impression posts corresponding to the custom abutments in dimensions and angulations allow the recording and transfer of the developed gingival profile from the mouth onto the working cast in order for the final prosthesis to be fabricated accurately, while they also have independent parts that improve the quality of the results of the implant treatment process. The custom abutments and impression posts moreover can be modified to be temporary abutments used to support a temporary prosthesis and can also be scanned by a digital scanner in order to generate a digital impression and or digital working cast. |
