Research Facts
Maxillary implant locators in regular stone model.
The model is made of regular stone, which is an adequate material for fabrication of an implant retained prosthesis.
In the model they have scribed a "post dam or finishing line" we do this to the model to know where the denture will end as well as compensation for the acrylic material shrinking while the acrylic is processing.
This looks like it might become an transitional/ temporary denture, which is made for the use of a few months to a year while the implant bone growth is occuring. After the necessary healing time has passed, a new denture or in this case most likely a bridge will be fabricated for a more permanent and aesthetic solution.
This type of implant, the metal screws which connect the denture to the base, were developed by Swedish surgeon Per-Ingvan Branemark in the 1960s, and they were a revolution in the field.
