Orthodontic set with guide cap and compatible screw

Description

Technical Field

[0001] The invention relates to an orthodontic set of a guiding cap and a compatible screw that allows the insertion of the orthodontic screw with the desired direction and depth to the bone.Prior art

[0002] WO2022035392A1 and WO2020245007A1 both show an orthodontic screw having a threaded head and a cylindrical neck with a smaller diameter than the threaded head. The threaded head engages a corresponding threading in a support bar.

[0003] In the classical method, the orthodontic appliances are supported by teeth. Nowadays, mini screws have been added to these classical appliances and bone-supported types have begun to be widely used.

[0004] Instead of getting support from the teeth, providing this support from mini screws that implanted into the palate bone, significantly increases the efficiency of the orthodontic appliance.Application steps of mini screw supported appliances

[0005] In order to apply a mini screw-supported orthodontic appliance in the mouth, screws must be inserted in the palate in the first appointment.

[0006] Afterward, the clinician must take an impression for inserted screws. This impression is sent to the technician and the mini screw-supported orthodontic appliance is prepared in the laboratory according to the position of the screws on the palate. In the second appointment, the appliance that comes from the technician is applied to the mouth.

[0007] In this method, it may be possible that the appliance does not fit properly on the screws. This is entirely dependent on the experience and skill of the clinician and technician. At the same time, the appliance must be applied at the next appointment, not at the first session where the screws are inserted.

[0008] In this old treatment method, the patient must make two appointments for the procedure. If the clinician could not place the mini screws in parallel in the first appointment, the appliance produced for the second appointment could not adapt on the screws. As a result of this technique used today, problems such as loss of time and repetition of production always pose a risk for clinicians.The Aim of the Invention

[0009] The invention relates to an orthodontic set of a guiding cap and a compatible screw that can solve the above-mentioned problems.

[0010] The main purpose of the invention is to ensure that the screw placed inside the guiding cap is applied in a single session, in the desired direction and depth, without deviation, with the help of the guide surface in the cap structure.

[0011] The aim of the invention is to enable orthodontists to successfully apply orthodontic appliances to patients at single session and without the need for additional operations.Detailed Description of the Invention

[0012] The subject matter of the invention, the orthodontic set of guiding caps, and the compatible screw are shown in the appended figures.Figures;

[0014] In the figures above, the parts are numbered as follows. 1-Screw 2- Guide surface inside the cap, compatible with the screw 3-Threaded head 4-Threaded part of the guide cap 5-Guide cap 6-Threaded tip of the screw 7-Cylinder guide surface compatible with the cap

[0015] The subject of the invention is a locking apparatus used in orthodontic operations comprising a screw and a guide cap as defined in claim 1.

[0016] It consists of a screw(1) that allows the appliance to be fixed in the palate bone. The guide cap(5) contains an inner guide surface(2) that allows the screw(1) to align in the desired direction. The threaded part of the cap (4) and the threaded head (3) of the screw head provide locking to each other (Figure- 1).

[0017] Structurally, the screw(1) consists of a threaded tip(6) which is inserted in the palate bone during the application and a cylinder guide surface(7) which has a flat form providing the screw (1) to be aligned in the guide cap(5).(Figure -2)

[0018] The guide cap(5) is the component that provides the locking of the screw and connection to the applaince(1). There are two structural parts in the guide cap (5), which are the inner guide surface(2) and the threaded part(3).

[0019] The guide surface inside the cap(2) is of the same form as the cylinder guide surface(7). The length of the guide surface inside the cap(2) is at least 1 / 3 of the length of the cylinder guide surface (7). When the insertion of the screw(1) in the palate bone is completed, the threaded head(3) is connected to the threaded part of the cap(4). (Figure -4)

[0020] The diameter of the cylinder guide surface(7) is greater than the diameter of the threaded tip of the screw end(6).

[0021] This allows the screw(1) to be inserted properly into the guide cap(5) and the operation can end safely(Figure-3).

[0022] As the screw (1) begins to move into the palatal bone, the cylinder guide surface (7) gets closer to the inner guide surface (2) of the cap. While the movement of the screw(1) , the cylinder guide surface(7) makes a tight fit into the guide surface inside the cap(2).

[0023] By aligning the cylinder guide surface(7) to the inner guide surface inside the cap(2), the screw(1) is prevented from bending and moving in an unwanted direction. This prevents anatomical tissue damage that may occur during application(Figure-5).

[0024] With the help of the guide surface (2) inside the cap, into which the cylindrical surface(7) on the screw (1) structure is aligned, the direction of the screw (1) in the palate bone is fixed during and after the operation, and in case more than one screw is used, they are ensured to be parallel to each other.

Claims

1. A locking apparatus for use in orthodontic operations, comprising a screw (1) consisting of a threaded tip (6) to be inserted in the palate bone, a cylindrical guide surface (7) continuing from said threaded tip (6) of the screw (1), and a threaded head (3) continuing from said cylindrical guide surface (7); and a guide cap (5) with an inner guide surface (2) that secures the alignment of said cylindrical guide surface (7) to said inner guide surface (2) allowing the screw (1) to advance in the palate bone without bending, and a threaded part (4) so that when the insertion of the screw (1) in the palate bone is completed, the threaded head (3) of the screw (1) is connected to the threaded part of the cap (4); wherein the diameter of said cylinder guide surface (7) is equal to the diameter of said threaded part of the guide cap (4).
