To make dentures, a dentist creates an impression of your teeth and gums. Usually the dentist sends this impression to a laboratory, which constructs a stone model of your teeth, then fashions the dentures out of acrylic to fit the stone model. This may require multiple steps in which the dentist presses soft molding material similar to clay into your mouth to create an impression, then receives the dentures, then tries them in your mouth and makes adjustments so they fit properly.

If we are speaking of full dentures, then a person has no remaining teeth. A dentist will take impressions of your mouth. The impressions will have dental stone placed in them and when dry they are placed onto a dental articulator.
The articulator simulates the workings of your mouth. It is a replication of the relationship of your upper to lower jaws, the amount of space between them as is used to place the denture teeth.
A dental laboratory is used to place the denture teeth with a written prescription from the dentist. The laboratory works with records that the dentist took of your mouth, which provides the relationship of the upper to lower jaws, placement of denture teeth and orientation.
Wax rims are used to show the dental technician where to place teeth. Denture teeth are placed and secured into place with wax. The wax is used to simulate the gum anatomy.
When all considerations are satisfied, the denture wax up is placed in a container. Stone is poured in to hold it in place. The wax is boiled out of the container, which leaves room where dental acrylic is placed and adheres to the denture teeth. When finished a new set of dentures.
Dentures may take 4-5 visits as each step goes back and forth to a dental laboratory.

Dentures are made by a dentist and a dental laboratory after a thorough dental exam and x-rays. Generally, 5 appointments are necessary to make a denture. At the first appointment, molds of the jawbones are taken so that a custom-fitting tray can be made for making the impression for the denture. At the second appointment the custom tray is used to make the impression from which the denture will be made. At the third appointment, the bite and position of the teeth are determined. The color, shape, and size of the teeth are selected. At the fourth appointment, the denture is tried in the patient’s mouth. The bite, position of the teeth, phonetics of speaking with the denture, and esthetics are checked are verified. Any necessary changes are made and the denture is sent to the dental lab for processing. The denture is delivered to the patient at the fifth appointment and adjustments are made if needed.
