Description

An Improved Frankel-III Functional Regulator

Technical Field

The utility model belongs to the technical field of oral equipment, and specifically relates to an improved Frankel-III function regulator.

Background Art

Class III malocclusion is a common malocclusion in clinical practice and is very common in children and adolescents. It not only has a serious impact on the normal growth and development of the craniofacial area, but also affects the individual's chewing, pronunciation and other aspects. If left untreated, the degree of tooth misalignment will gradually worsen over time, leading to more serious dental and maxillofacial deformities, affecting beauty and self-confidence.

In orthodontics, the importance of tongue muscles in Class III malocclusion cannot be ignored. The tongue muscle is one of the important muscles in the oral cavity and plays a vital role in the growth and development of the maxillary and mandibular bones. In Class III malocclusion, it is generally believed that when the maxillary bone is underdeveloped, the maxillary arch is narrow or the palate is flat, the maxillary intrinsic oral volume is reduced, forcing the tongue to move forward and downward, which has an abnormal driving effect on the mandibular dental arch, or because of the need for respiratory function, the tongue moves forward, driving the mandible to continue to protrude. Therefore, tongue muscle abnormalities can lead to abnormal activities such as swallowing and language, which have a negative impact on the formation and development of Class III malocclusion.

Functional appliances can act on the lips, tongue, and jaw lifting muscles, etc. The functional activities of the oral and facial muscles and abnormal muscle habit positions are the main causes of malocclusion. The Frankel-III functional adjuster is an oral appliance used to treat Class III malocclusion. It is often used in orthodontic treatment for adolescents. It acts on the oral and facial muscle environment, adjusts the relationship between the upper and lower jaws, and restricts the growth of the mandible to correct the misalignment of teeth, thereby guiding the normal development of the jaw and dentition. This appliance has a simple structure, is easy to wear, and can correct Class III malocclusion. However, traditional Frankel-III functional adjusters usually have the following defects:

(1) The traditional Frankel-III functional adjuster cannot maintain the correct position of the tongue during swallowing and chewing. The traditional Frankel-III functional adjuster is equipped with a palatal arch and a lingual arch, which blocks the tongue from expanding the maxillary dental arch. The mandibular buccal screen can resist the lateral movement of the tongue, but cannot prevent the tongue from expanding the mandibular dental arch in the sagittal direction. In the presence of abnormal tongue body and tongue position, the tendency of the mandibular arch to continue to protrude may be increased. In the treatment process of the traditional Frankel-III functional adjuster, speech training and oral rehabilitation are needed to improve the movement and position of the tongue muscles, thereby helping the tongue muscles to play a normal role in growth and development.

(2) When discussing the formation mechanism of Class III malocclusion, the traditional Frankel-III functional regulator places more emphasis on limiting the sagittal and horizontal muscle tension of the upper lip and cheek muscles, and creates lip stops and cheek guards to counteract this muscle tension. However, it does not pay enough attention to the position and activity of the tongue muscles that maintain the balance of muscle dynamics inside and outside the oral cavity, and does not provide targeted corrections.

(3) Skeletal Class III malocclusion is usually accompanied by the lower front teeth tilting inwards and the upper front teeth tilting outwards. This is a compensatory phenomenon to allow the upper and lower teeth to occlude better. This compensation cannot be limited by the traditional Frankel-III functional adjuster. When using the traditional Frankel-III functional adjuster for correction, the compensatory phenomenon of the lingual tilt of the lower incisor may continue to exist, thus affecting the correction effect.

Please refer to FIG. 1 , and the improved Frankel-III functional regulator provided by the embodiment of the utility model will now be described.

As shown in Figure 1, the improved Frankel-III functional regulator of the embodiment of the utility model includes a cheek guard 1, a lip guard 2, a tongue guard 3 and a wire part, and the wire part includes a lip guard connecting wire 4, a mandibular labial arch 5, anterior palatal arch 6, posterior palatal arch 7 and a jaw support 8.

The cheek shield 1 is provided with two, namely the left cheek shield 1a and the right cheek shield 1b. The cheek shield 1 is used to be placed in the upper and lower vestibule grooves when correcting deformities, and its distal part covers the end of the molar, and the mesial part covers the distal of the canine. In this embodiment, the cheek shield 1 is a thermosetting plastic plate with a thickness of 1mm to 3mm to ensure the stability and durability of the cheek shield 1; the maxillary part of the cheek shield 1 is 3mm away from the upper alveolar space to provide an expansion space for the maxillary teeth; the mandibular part of the cheek shield 1 fits the upper alveolar space; and the shape of the cheek shield 1 should be adapted to the shape of the dental arch to ensure that the cheek shield 1 can fit the cheek correctly.

The left and right ends of the lip stopper connecting wire 4 are respectively fixedly connected to the front upper part of the left cheek screen 1a and the front upper part of the right cheek screen 1b; the lip stopper 2 is fixed on the lip stopper connecting wire 4, and the lip stopper 2 is used to fit the mucosal turning point of the labial side of the upper incisor when correcting the deformity. In this embodiment, the diameter of the steel wire used in the lip stopper connecting wire 4 is 0.8mm-1.2mm, preferably 0.9mm, and the material is stainless steel to ensure the stability and durability of the lip stopper connecting wire 4; the lip stopper 2 is symmetrically provided with two, and the lip stopper connecting wire 4 between the two lip stops 2 is U-shaped and avoids the upper lip frenulum; the lip stopper 2 is a thermosetting plastic plate with a thickness of 2mm to 3mm; the distance from the lip stopper 2 to the maxillary vestibule is 3mm to 5mm, and the lip stopper 2 is parallel to the alveolar ridge; the distance from the upper edge of the lip stopper 2 to the mucosal membrane of the labial side of the upper incisor is 1mm to 2mm. This design enables the lip stopper to effectively act on the upper lip and push the upper lip forward, forming a negative pressure space between the upper lip and the maxilla, which can promote the forward and outward growth of the maxilla. At the same time, such a lip stopper can also limit the closure of the upper lip, so that the upper lip cannot form a closed ring with the lower lip, which will inhibit the development of the maxilla; it can also increase the tension of the upper lip, so that the upper lip exerts a continuous pulling force on the maxilla, which can stimulate the bone hyperplasia of the maxilla. Therefore, the stimulation of the maxilla by the lip stopper is through multiple mechanisms, making the development of the maxilla more balanced and coordinated.

The left and right ends of the anterior palatal arch 6 are respectively fixedly connected to the front middle of the left cheek screen 1a and the front middle of the right cheek screen 1b. The anterior palatal arch 6 is used to pass through the distal surface of the canine and fit on the lingual protuberance of the upper incisor of the patient's palate when correcting the deformity. In this embodiment, the diameter of the steel wire used in the anterior palatal arch 6 is 0.8mm-1.2mm, preferably 1.2mm, and the material is stainless steel to ensure the stability and durability of the anterior palatal arch 6; when in use, a pre-tightening force can be applied to the anterior palatal arch 6 to slightly push the upper front teeth forward.

The front part of the anterior palatal arch 6 is covered with a protective pad 9 in contact with the lingual side of the upper incisor; the tongue grid 3 is composed of a plurality of steel wires extending downward, the upper end of the tongue grid 3 extends into the protective pad 9 and is fixedly connected to the anterior palatal arch 6, and the tongue grid 3 is used to be set between the two canines on the maxillary palate side when correcting deformities, and is adapted to the patient's tongue size and the distance from the tongue tip to the center of the front teeth. In this embodiment, the protective pad 9 is preferably a thermosetting plastic plate. In order to make the tongue grid 3 have good strength and air permeability, 4 steel wires of the tongue grid 3 are arranged at intervals, and the diameter of the steel wire of the tongue grid 3 is 0.8mm-1.2mm, preferably 0.8mm.

The left and right ends of the mandibular labial arch 5 are respectively fixedly connected to the front lower part of the left buccal screen 1a and the front lower part of the right buccal screen 1b. The mandibular labial arch 5 is used to fit in the middle of the labial side of the lower incisor and slightly apply a pre-tightening force when correcting deformities. During production, a small groove is engraved on the neck of the lower front teeth of the mandibular working model, which is equivalent to the position of the cusp papilla, and the bent mandibular labial arch 5 is placed in the small groove. This ensures that when the orthodontic appliance is worn, the lower labial arch 5 is in close contact with the lower front teeth, and the mandibular labial arch 5 is placed as close to the neck of the lower front teeth as possible to prevent the lower front teeth from lingually tilting. In this embodiment, the diameter of the steel wire used for the mandibular labial arch 5 is 0.8mm-1.2mm, preferably 1.2mm, and the material is stainless steel to ensure the stability and durability of the mandibular labial arch 5.

The left and right ends of the posterior palatal arch 7 are respectively fixedly connected to the middle of the rear side of the left cheek screen 1a and the middle of the rear side of the right cheek screen 1b. The posterior palatal arch 7 is used to pass through the distal surface of the last molar and fit on the upper palate of the patient when correcting the deformity. In this embodiment, the diameter of the steel wire used in the posterior palatal arch 7 is 0.8mm-1.2mm, preferably 1.2mm, and the material is stainless steel to ensure the stability and durability of the posterior palatal arch 7.

The jaw supports 8 are provided with two, namely the left jaw support and the right jaw support. The left jaw support extends from the middle of the back side of the left cheek screen 1a and bends forward, and the right jaw support extends from the middle of the back side of the right cheek screen 1b and bends forward. The jaw supports are used to be placed in the central fossa of the bilateral second deciduous molars or the first permanent molars when correcting deformities, thereby limiting the outward expansion of the posterior molar area, which helps to correct the molar relationship of Class III malocclusion and plays a role in auxiliary fixation. In this embodiment, the steel wire used in the jaw support 8 has a diameter of 0.8mm-1.2mm, preferably 1mm, and is made of stainless steel to ensure the stability and durability of the jaw support 8.

In summary, the improved Frankel-III functional regulator of the utility model is particularly suitable for developmental Class III malocclusion patients with a large tongue, bad tongue habits, and a tongue that leans forward and downward. It can effectively restore the normal position of the tongue, maintain the balance of muscle strength inside and outside the oral cavity, alleviate the compensatory trend of the upper and lower front teeth, promote the forward development of the maxilla, inhibit the continued forward and downward growth of the mandible, and will not aggravate the existing malocclusion. It has high clinical use value.

The above is only a preferred embodiment of the present invention.
