Research Facts
Mandibular (lower jaw) implant locators in a die stone model with simulated gingiva (gum) silicone.
As in the previous photos, the "grey" stone is known as die stone. For this model, the implant locators are again covered in silicone to preserve the details of the implant base. These implants could possibly be used for an anchor for a bridge, using the implants and the remaining closest tooth for anchors.
The difference between a bridge and a crown: a bridge will use neighboring teeth for support and a crown gets the support from the tooth it is placed on or an implant.
On the back of the front teeth looks to be a cemented retainer that was picked up in the impression. This is used to keep the teeth in their proper position after braces (orthodontic treatment)
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.
