The goal of construction of occlusion rims is:
1- To obtain the occlusal plane, vertical dimension, tentative centric relation, face low transfer, placement of the teeth. ***
2- To obtain the protrusive condylar guidance.
3- To obtain the lateral condylar posts and incisal guide.
4- None.

The occlusal plate, also called "occlusal splint", is a temporary dental appliance, entirely made in dental laboratory, transparent or opaque, resin, hard or soft. In the latter case, these are thin plates preformed industrially and then thermoformed on plaster models of the dental arches of the patient.
The occlusal plate should never be confused with a "retro-incisive bite plan" (PMRI), a transitional device made of transparent, hard, self-curing resin.
It is worn exclusively in the upper jaw and is mainly made in the mouth in order to effectively treat oral dysfunction (PMRI and PMRI-PO).
Occlusal treatment is followed by a permanent fixed prosthesis made of metal or porcelain; to be as durable in time as the enamel of natural antagonistic teeth (opposite teeth).

The occlusal splint helps to restore normal dental occlusion in case of joint problems in the lower jaw.
It is worn on the entire dental arch, usually the bottom, to create an extra thickness between the teeth

Definition and uses of the occlusal splint:

What is an occlusal splint?
The occlusal splint, or protective gutter, is a kind of fitted and thin mouthguard, usually made of resin.
It is most often placed on the teeth of your lower jaw.
Its purpose is to prevent complete occlusion of your teeth to relax your masticatory muscles.
It allows to create an extra thickness to act on the contacts between your teeth.
The occlusal splint can be flexible or rigid and there are two types: those found in the trade and those made at your dentist, thermoformed gutters (adjusted to the teeth through heat).
The latter fit perfectly to the shape of your dental arch.

Different uses of an occlusal splint:
The occlusal splint, often mandibular (placed on the lower jaw), is used to treat bruxism (nocturnal grinding of teeth) and SADAM (algo-dysfunctional syndrome of the manducatory system).
- In the case of bruxism, the occlusal splint is worn at night and relieves too much clenching of teeth by releasing the masticatory muscles.
- In the case of SADAM, she wears all day except during meals.
This syndrome is an operating disorder of the joint between the skull and the lower jaw, the temporomandibular joint (TMJ), placed in front of the ears.
It causes joint and muscle pain in this region.

Properties of the occlusal gutter:
Occlusal splints are usually made of resin or plastic.
Occlusal splints for the treatment of muscle and joint pain (bruxism or TMJ dysfunction) are made "custom-made" by your dentist from the imprints of your teeth.
They are then made by a prosthetist and are perfectly adjusted and molded on your dental arch.
The thermoformed gutters have the property of keeping themselves adjusted to the shape of the teeth after having been heated.
They adapt to dental contacts, to your occlusion.
This type of gutter needs to be adjusted regularly (once a month, at the beginning) by your dentist, then replaced in case of wear (after 1 to 3 years).

How much does an occlusal splint cost?
The cheapest occlusal gutters, but not adapted to your own occlusion, are the commercially available gutters. We find them between 50 and 80 €.
The most reliable gutters are the occlusal splints made to measure at the dentist's.
Their price is around 200 € including the imprints of your teeth and the installation of your occlusal gutter adjusted.
Social Security reimburses 70%, like a dental care. You can ask your mutual to refund the remaining 30%.
