What are the basic uses of dental disposable oral molds?

The primary use of impressions in dentistry is to produce accurate (varying degrees of accuracy) negative reproductions of the teeth, surrounding tissues and dental arches. These impressions are used for fabrication of various dental prostheses, including crowns, bridges, veneers and dentures, to name a few.

During the impression making process, your healthcare provider will dispense a putty-like impression material into plastic or metal trays. These trays are then placed over your teeth, where the impression material sets and hardens.

A dentist will then send the trays to a dental laboratory where a technician will pour stone into your impressions to create a cast of your mouth. The cast, or negative impression, will be a precise, custom-fit model that will help the dental lab develop your dental restorations.

Digital Impression Systems

The latest in impression technology is digital mouth scanning, which uses lasers or optical scanners to capture the details of your teeth and gums. The digital data is then transferred to a computer, where it can be used to design and mill your restorations, often in just one appointment.

Currently, dental impressions are made with a variety of materials, but technique, accuracy, taste, ease of manipulation, cost and dimensional stability all play a role in choosing the best material for your case. Using the wrong material can lead to delays and complications in your dental treatment. In addition, impression materials can be toxic to your body.
