Molds for fabrication of custom and potentially modifiable abutments and impression posts for dental implants with various degrees of angulations (including zero degrees) and various dimensions are provided, with a generally oval shape that expands laterally upwards, a symmetrical or asymmetrical cross-section, and regular surfaces, that are fabricated as one piece, or as two coupling pieces snapping onto each other. Custom abutments achieve the development of a custom gingival emergence profile, three dimensionally, which is potentially modifiable according to the needs of each particular clinical case. Custom impression posts that correspond in dimensions and angulations to the abutments allow the accurate recording and transfer of the developed gingival emergence profile from the mouth onto the working cast, where the final implant prosthesis is fabricated. The custom abutments and impression posts have properties and design that allows their preparation and usage as temporary abutments for the cementation and support of temporary prostheses, following the same principals as per teeth temporary rehabilitation, but they can also be scanned by a digital scanner for the generation of a digital impression and the fabrication of a digital prosthesis. |
