How custom-made sport guards appliances have been fabricated?
Steps in fabrication of custom made mouthguards.
Step 1: Impression Taking. It is recommended that dentists produce casts from accurate maxillary and mandibular alginate impressions and a centric occlusion registration at approximately 5-mm opening anteriorly.
This is made possible by taking an impression of the mouth. A negative copy of the upper and lower teeth is taken, so that a plaster cast can be created from it. The cast is also called the model cast or mould and it is used by the dental laboratory to make the custom sport guard.
Step 2: Sport Guard Fabrication. Several options in the manufacture of custom-made mouth guards are available with respect to materials and developed techniques. The standard thickness is 4-mm for most contact sports. The dental mould plays a key role in how the guard is fabricated. The material is shaped around the mould to form a perfect-fitting protective barrier for upper and lower teeth.
Step 3: Delivery. As soon as the sport guards have been fabricated, they are delivered to the patients along with proper instructions for wear and care.
