Dental waxes are used in restorative dentistry for laboratory procedures. They are thermolastic materials supplied in various forms like sheets and sticks. Dental waxes are used to make wax designs for complete and partial dentures, inlays, crowns and bridges. They are also used for boxing in impressions before pouring models and for registering occlusal bite relationships. Dental waxes come from natural sources like minerals, insects and vegetables or are made synthetically from petroleum. Common dental waxes include pattern waxes, processing waxes, and impression waxes used for tasks like making wax patterns and boxing impressions.
