PR-M (prevention – primary dentition)
The PR-M helps to wean harmful sucking habits and other malfunctions of the oral musculature. It has an ideal semi-circular shape for the rows of milk teeth. This allows teeth which are outside the dental arch to align due to the restoring force of the silicon material. The PR-M consciously closes the mouth without leaving any air slits in order to achieve more healthy nasal breathing instead of oral respiration.
- open mouth posure
- false resting position of the tongue
- poor lip closure due to muscular weakness
- infantile swallowing
PR-W (prevention – mixed dentition)
It´s efficacy lies in the restoring force of the basic material. It is able to align malpositioned teeth into an ideal dental arch. Extensive teeth movements are, however, limited and not comparable to the possibilities of other removable or permanently fitted dental braces. By shielding soft tissues which interfere in the mouth (tongue and mucous membranes of the cheek) as well as activating the musculature of the mouth and lips by the PW-W, the crooked teeth can align themselves into the correct position.
Training device for:
- open mouth posture, which leads to an imbalance in the oral cavity and to restrictions of the jaw
- removal of health-damaging oral respiration
- breaking sucking habits of all kinds
- alignment of irregularly erupting teeth
OB-M (open bite – primary dentition)
The OB-M for the treatment of frontal open bite in the primary dentition has an extended and strongly retroverted lip screen. In this way, the shortened upper incisors and the arched jaw section are complety enclosed.
The effect of the OB-M in eliminating the open bite is initially indirect: the tongue is prevented from permanently lying between the incisors. In this way, the teeth may extend further in a self-regulating manner.
OB-W (open bite – mixed dentition)
The OB-W for treatment of frontal open bite has an extended and strongly retroverted lip screen for the upper jaw. In this way, the shortened upper incisors and the arched jaw section are completely enclosed.
The effect of the OB-W when eliminating open bite is initially only indirect: the tongue is prevented from permanently lying between the incisors. In this way, the teeth may extend further in a self-regulating manner. In addition, a direct effect by pacing the lip screen of the upper jaw on the mostly protruding and shortened teeth is achieved, which in this way are guided towards the palate and lengthened at the same time.
By closing the open bite, incorrect articulation is removed, pronunciation improves and biting with the incisors is possible again.
Class II-M (lower jaw retraction - primary dentition)
The Class II-M is indicated for treating a retrusive bite of the lower jaw including elimination of the incisor ledging. The lip screen for the upper jaw is extended and strongly angled backwards. In this way, the mostly forward inclined incisors and the anterior alveolar process are completely enclosed.
The elimination of incisor ledging takes places partly indirectly by stimulating growth of the lower jaw.
Furthermore, there is a direct effect of the Class II-M by placing the particularly inclined lip screen against the mostly protruding incisors. These are guided toward the palate, which contributes to reduction of incisor ledging. The pronunciation is mostly improved and biting with the incisors is made easier by eliminating the incisor ledging.
Class II-W (lower jaw retraction – mixed dentition)
The Class II-W for treatment of a retrusive bite of the lower jaw including the removal of the incisor ledging has an extended and strongly retroverted lip screen for the upper jaw. In this way, the mostly forward inclined incisors and the anterior alveolar process are completely enclosed.
The effect of the Class II-W and the elimination of icisor ledging takes places party indirectly by stimulating growth of the lower jaw which incorrectly tends backwards. In this way, the position of the lower jaw to the upper jaw is aligned. This removes the incisor ledging. In addition, there is a direct effect by placing the lip screen of the upper jaw on the mostly spaced protruding incisors. They are guided toward the palate, which contributes to the reduction of incisor ledging. By removing the incisor ledging, pronunciation is improved and biting with the incisors is made easier.
DB-W (deep bite – mixed dentition)
The DB-W is used for elevating a distinct deep overbite and traumatic biting. The lip screen for the upper jaw has a steeper inclination, in order to allow the upper incisors which are mostly inclined toward the palate to straighten up. With the DB-W only the incisors of the upper and lower jaws bite on the device so that blocking of the posterior occlusal area takes place.
The effect of the DB-W is indirect due to the bite blockage of the posterior teeth. It stimulates the vertical growth of the posterior teeth according to the principle bite elevation of functional orthodontic devices (activator, bionator, functional regulator etc.).
BR-W (bruxism – mixed dentition)
The BR-W is indicated for treatment of infantile bruxism. It is manufactured from elastic silicone, which is able to withstand stronger chewing pressures, such as nightly teeth grinding.
Its effectiveness arises from the teeth clenching, which leads the grinding to stop and the jaw joint to relief. At the same time, the teeth are protected against abrasion and damage of the enamel. In case of other malfunctions due to the tongue or malalignments, these can also be stopped with the BR-W.
