As is known, the upper jaw (maxilla) consists of two bones, and these two bones... There is a connective tissue (suture) between them. This anatomical structure thanks to upper jaw, palate and jaw expansion devices It is being expanded. Especially for straightening crooked and poorly positioned teeth. 15 palate expansion appliances used in orthodontic treatments that facilitate alignment Its use is well known. Palate and jaw expansion devices, for malocclusions. to correct and provide the necessary space for the alignment of the teeth the bony structure in the jaw and palate region or the palate between the molar teeth It is placed in that region and applies force to the teeth, causing the upper molar It causes the teeth to move towards the cheek side. Thus, 20 The upper jaw is widening, the arch perimeter where the teeth are aligned is increasing, and Space is created for the crowded teeth. The palate is adjusted according to the area where support is received. and jaw expansion devices with tooth-tissue support and / or bone support or being hybrid, supported by both teeth and mini screws. It is divided into three main parts. 25 Dental tissue-supported palate and jaw expansion devices help narrow jaws. widening, moving the molar and premolar teeth towards the cheek side for the purpose of removing hard and / or soft tissues from the teeth and / or palate area They fulfill their duties with the support of others. Thus, complexity and 30 In cases of jaw narrowing, teeth can be aligned without extraction, and Space is gained. Palate expansion devices supported by bone tissue are used. 2022.146 2 via mini screws or implants to the upper jaw palate surface It is being fixed. In one of the applications that exist in the known state of the art, the screw The carriers on it are a detachable, needle-shaped, pointed 5 It moves by turning the key around its own axis. This type In palate expansion devices, the patient's palate can be expanded. the wrench should fit perfectly into the hole on the screw and rotate on its own axis turning it around, and then removing the key again when the process is complete. It is necessary. However, it is quite difficult for the patient to perform this procedure. 10 and the operation is being performed by someone else, rotating around its own axis When the operation cannot be completed properly, the hole on the screw cannot be reached. Treatment flow is disrupted and creates bigger problems. Other One problem is when inserting the wrench, which has a needle-like tip, into the hole in the screw. This occurs when the key doesn't fit perfectly into the lock. 15 There is a risk of the key slipping and penetrating the palate, injuring the patient. The most important problem is when turning the screw with a wrench. The key could be dropped into the patient's mouth, posing a risk of the patient swallowing it. An application included in the known state of the art is 20 US7780445. It is described in a United States Patent. By sliding along the screw. a palate expander that opens and closes with a movable arm It is explained. Another document included in the prior art is EP2155104, number 25.

The palate and jaw expansion device described in the attached requests, carriers a screw that is moved by means of a lever that acts as a handle It involves a movement mechanism and balance through that movement mechanism. between the rod, the channel on the movement mechanism and this channel 5 By establishing a direct relationship with the seating of the protrusion on the balance bar. obtaining a more robust, safer and more precise tool This allows for more precise opening with arm movement. This is also achieved. For example, a 0.2 mm opening with one movement of the arm. is provided. 10 This invention allows the arm to be rotated around the horizontal axis along which the screw extends. Thanks to this, it can be activated or deactivated simply by pushing or pulling the lever. A palate and jaw expansion device has been developed that is put into a passive position. Gears that form the motion mechanism and move in one direction only. Thanks to this, the carriers can screw in more precisely, accurately and securely. to move on it and stop at the desired position This is ensured. Since the gears can move in only one direction, the carriers This prevents the screw from moving backward and the existing 20 They are enabled to maintain their positions. Screw threads tapped in opposite directions on both sides of the screw. This allows the carriers placed on both sides of the screw to be positioned. 25 This ensures that carriers, in the application of the invention, only The pieces move towards each other as they are assembled. The balance bar is positioned parallel to the screw, and the supports are attached to the screw. It ensures that they move stably on it. Balance bar 30 It guides the movement of the carriers on the screw. At the same time... the protrusion fitting into the channel located on the movement mechanism 2022.146 4 thanks to which the movement mechanism stays together on the screw and During the opening process, an undesirable situation occurred: the balance bar's single unit... It prevents unilateral slippage. Additionally, it expands the palate and jaw. The screw and the balance bar must be engaged when switching the device between the on and off positions. It is also ensured that it remains there. 5 Palate and jaw expansion device attaches to teeth inside the mouth via retainers. It can be fitted. Additionally, a palate and jaw expansion device can be fitted with the help of holders. via mini screws or implants on retainers, directly to the palate It can be fixed onto it. In addition, it can be attached to both teeth and mini 10 It is applied in a hybrid manner, supported by screws. All three In practice, the working principle of the palate and jaw expansion device is the same. Only the parts at the ends of the holders need to be replaced. In one application of the invention, the balance on the carriers, in the closed position, is 15. a step on the protrusion on the bar and where the first set sits It is located. The depth of this level is at least the protrusion and the thickness of the first set. It is approximately the size of a protruding part and fits into the first set of steps. The surface facing the carrier's movement mechanism is flush with the carrier's surface. This In this way, without increasing the size of the palate and jaw expansion device, the opening is 20 by increasing its capacity, the balance bar has more space between the carriers. It is made to move. In one application of the invention, a palate and jaw expansion device, maximum When it reaches the opening, it holds together even if turned further, the palate and 25 The parts that make up the jaw expansion device are separated from each other. both sides of the balance bar prevent it from falling apart and ensure it locks in place. With the first stopper located at the end, the carriers achieve maximum span. when it reaches the first stopper, inside the first hole It includes a step that narrows the diameter of the hole. This allows the patient to 30 the palate and jaw expansion device located inside the patient's mouth The pieces disperse inside, preventing the patient from swallowing them. 2022.146 Also, the palate and jaw expansion device, the second hole, the second set and the first on the adjacent side of the set, having a diameter larger than the diameter of the second hole, It includes a second stopper that has no grooves on its surface. Thus, the palate and the jaw expansion device, when it reaches maximum opening, is inside the carrier 5 In this second, non-grooved stopper, the screw rotates freely, expanding the palate and jaw. the parts that make up the instrument falling apart and into the patient's mouth is prevented. In one application of the invention, the first gear and the lever are interconnected. It is manufactured in parts. This minimizes the risk of the arm breaking. It is being downloaded. With this invention, 10 applied to the arm with just one finger. The palate and jaw expansion device is activated by pushing or pulling force. or it is brought to a closed, passive position. Thanks to this invention, orthodontic treatments benefit both the doctor and the patient. The palate and jaw expansion device provides comfortable use, 15 Palate and jaw expansion device can be used easily and without wasting time. after it is securely attached and the upper jaw expansion procedure is complete is extracted. With this invention, the palate and... can be extracted quite practically with the help of the arm. A jaw expansion device can be used. The patient can easily use it themselves. Turn the palate and jaw expansion device to the active or passive position 20 It is able to do so. The movement mechanism is a one-way gear system. It can be set up like a jack, resulting in the arm going full and coming back empty. It is possible to achieve this. In addition, thanks to the invention, other palate and jaw expansions can be performed. The size can be made quite small depending on the devices. This situation affects the patient. By increasing comfort, it allows the patient's tongue to feel more comfortable. 25 In addition, the palate and jaw expansion device is robust and safe. Its use is also increasing.
