Description

Technical Field

[0001] This invention relates to the field of dental instrument technology, and in particular to a rinsing assembly and opening method for a maxillary fixed spiral expander base. Background Technology

[0002] Maxillary fixed rapid arch expansion is a common method for treating maxillary hypoplasia. In clinical treatment, patients often experience problems such as palatal mucosal sensitivity, inflammation, and even bad breath due to food residue on the base of the maxillary fixed arch expander and inadequate cleaning. Effective cleaning methods can significantly reduce these clinical pain points.

[0003] Patients using maxillary fixed spiral expanders with plastic bases all showed varying degrees of food debris accumulation on the palatal side of the plastic base during clinical follow-up visits. This food debris was in direct contact with the palatal mucosa, but effective cleaning methods and means were lacking. This food accumulation not only easily caused bad breath, but may also trigger inflammation of the palatal mucosa, leading to redness, swelling and pain on the palate. Furthermore, the accumulated food debris may cause dysbiosis in the oral environment, resulting in other oral mucosal diseases caused by dysbiosis.

[0004] During maxillary expansion treatment, there are currently no means or equipment to directly clean the space between the base of the maxillary fixed spiral expander and the palatal mucosa. The existing technology "CN223143618U" is only used to clean around the implant pin of the maxillary fixed spiral expander, but it still cannot solve the problem of food residue between the maxillary fixed spiral expander with plastic base and the mucosa. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a rinsing component and opening method for a maxillary fixed spiral expander base. This rinsing component is suitable for patients in the maxillary expansion stage, and its main function is to clean the gap between the plastic base of the expander and the palatal mucosa, reducing oral problems caused by food residue.

[0006] To achieve the above-mentioned objectives, the technical solution of this invention is as follows:

[0007] A rinsing assembly for a maxillary fixed spiral expander base includes a rinsing head for rinsing the maxillary fixed spiral expander base by inserting it into an opening in the base, and an opening device for opening the maxillary fixed spiral expander base.

[0008] The flushing head includes a flushing head, a water outlet, a water outlet pipe, a water outlet tube, and metal wires inside the pipe wall.

[0009] The flushing head is a cone-shaped body with a base larger than the top. The flushing head has an outer surface that matches the opening of the maxillary fixed spiral expander base so that it can be inserted and fitted into the maxillary fixed spiral expander base. After the flushing head is inserted into the opening of the maxillary fixed spiral expander base, the outer surface of the flushing head inside the base corresponds to the shape of the opening of the maxillary fixed spiral expander base, so that the water outlet of the flushing head can enter the gap between the base and the palatal mucosa when the maxillary fixed spiral expander base is inserted.

[0010] Outlets: Outlets are evenly distributed around the end of the rinsing head and are connected to the water outlet pipe; the water outlet direction is directly opposite the rinsing gap between the opening of the maxillary fixed spiral expander base and the palatal mucosa.

[0011] Water outlet pipe: Connected to the bottom of the flushing head, it is a flexible material pipe that is easy to bend;

[0012] Water outlet pipe: a hollow pipe installed inside the water outlet pipe;

[0013] Metal wire inside the pipe wall: embedded between the pipe walls of the outlet pipe and the outlet pipe;

[0014] Opening: The opening of the maxillary fixed spiral expander base, machined on the maxillary fixed spiral expander base, is located between the metal wires inside the tube wall of the maxillary fixed spiral expander base. The two maxillary fixed spiral expander base openings in the single maxillary fixed spiral expander base are located on the palatal side of the deciduous canine region and the region from deciduous molar to first molar in the mouth. The gap between the maxillary fixed spiral expander base opening and the palatal mucosa is the rinsing gap. The gap between the palatal side of the maxillary fixed spiral expander base opening and the palatal mucosa is the fixed gap. The fixed gap is used for the entry of the rinsing head, and the rinsing gap is used for rinsing the opening. The width of the rinsing gap is greater than that of the fixed gap. During rinsing, the water flow enters the fixed gap from the rinsing gap.

[0015] As a preferred embodiment, the flushing head is made of rigid plastic, and the top of the flushing head is provided with a solid soft rubber ball head. A ring of protrusions at the junction of the soft rubber ball head and the rigid plastic forms the most prominent edge of the rigid head of the flusher. The water outlet is located slightly towards the end of the water outlet pipe body of the most prominent edge of the rigid head of the flusher.

[0016] As a preferred embodiment, the rinsing head has an adhesive soft rubber ball embedded at its tip to reduce the irritation to the palatal mucosa when the rinsing head enters the opening of the maxillary fixed spiral expander base; the diameter of the soft rubber ball is smaller than the diameter of the most protruding edge of the rigid tip of the rinsing head, and the soft rubber ball is fixed to the tip of the rinsing head by adhesive bonding inside the rinsing head.

[0017] As a preferred embodiment, the aperture holder is divided into a positioning body and a retaining body.

[0018] The retainer includes: a concentrically arranged retainer base, a retainer, a retainer base functional surface, and a retainer palatal suction cup.

[0019] The base of the retaining post is wider at the lower end away from the retaining post than at the upper end near the retaining post.

[0020] Retention post: Connected above the retention post base, the retention post is used to fix the in place body during the base opening molding;

[0021] The functional surface of the retention post base is the outer contour surface of the retention post base. The functional surface of the retention post base is a downwardly widening slope. The downwardly widening slope of the functional surface of the retention post base is used to create a certain gap between the opening on the palatal side of the base and the palatal mucosa when the opening of the base is formed during the molding of the maxillary fixed spiral expander base. This gap connects the fixation gap and the rinsing gap, so that when the rinsing head is used at the opening of the maxillary fixed spiral expander base, the water flow can smoothly enter the rinsing gap and the fixation gap from the opening.

[0022] Palatal suction cup for retention body: Connected below the functional surface of the retention post base, used to fix the base of the maxillary spiral expander. During the drilling and molding process, the retention body can be adsorbed onto the palatal top of the maxillary model to complete the fixation of the retention body.

[0023] The in-place body includes the body portion, the retention channel, and the functional surfaces.

[0024] The body of the placement device: After the base of the maxillary fixation spiral expander is formed, the placement device is removed from the opening of the base of the maxillary fixation spiral expander;

[0025] The positioning body retention channel is a hollow tube located inside the upper part of the positioning body. The diameter and depth of the tube correspond to the size and length of the retention post of the cylindrical positioning body. The edge of the base plane of the retention post of the positioning body is aligned with the edge of the wall of the positioning body retention channel, so that the palatal opening and the lingual opening are smoothly transitioned when the base of the maxillary fixation spiral expander is formed, without the generation of a stepped plane.

[0026] The positioning body functional surface is formed by the outer contour surface of the upper end of the positioning body fixation channel. The positioning body functional surface is a downwardly widening inclined surface. The axial convergence degree of the positioning body functional surface corresponds to the shape of the rinsing head. The positioning body functional surface is used for the lingual opening of the maxillary fixed spiral expander base during molding. The shape of the positioning body functional surface corresponds to the shape of the lingual opening of the base and the shape of the rinsing head, so that the rinsing head can smoothly enter the opening of the maxillary fixed spiral expander base and maintain a tight fit with the opening of the maxillary fixed spiral expander base.

[0027] As a preferred method, the palatal opening shape of the maxillary fixed spiral expander base corresponds to the size and shape of the functional surface of the retention post base, and the lingual opening shape corresponds to the size and shape of the functional surface of the insulated body.

[0028] As a preferred embodiment, the palatal suction cup of the retainer is circular.

[0029] As a preferred embodiment, the upper end of the positioning body is a gradually decreasing frustum shape, and the lower end is a cylindrical positioning body portion, with the positioning body portion and the positioning body fixation channel being concentrically arranged.

[0030] As a preferred embodiment, the positioning channel is a hollow cylindrical channel.

[0031] A second objective of this invention is to provide a method for opening a flushing assembly of a maxillary fixation spiral expander base, comprising the following steps:

[0032] (1) Place the aperture holder at the opening position on the model for fabricating the maxillary fixed spiral expander. The opening position is located in the maxillary bilateral anterior tooth region and the maxillary bilateral deciduous or permanent molar region. Use the palatal suction cup of the abutment to attach it to the model for fabricating the maxillary fixed spiral expander before the base of the maxillary fixed spiral expander is molded.

[0033] (2) After adsorption and fixation are completed, the body is fitted to ensure that the fixation column of the fixation body is completely inserted into the fixation channel of the body.

[0034] (3) After fixation, the base of the maxillary fixed spiral expander is filled with glue and molded. After molding, the body is removed and the molded maxillary fixed spiral expander and the base of the maxillary fixed spiral expander can be removed, thus completing the opening of the base of the maxillary fixed spiral expander.

[0035] As a preferred embodiment, the method of creating the opening involves making different numbers of openings on a single-sided base.

[0036] The working principle of this invention is as follows:

[0037] Connect the irrigator head to the water outlet container. Before use, bend the water outlet tube of the irrigator head to a suitable shape. Insert the irrigator head into the opening of the base of the maxillary fixed spiral expander, ensuring a tight fit between the irrigator head and the opening. The water outlet should be positioned in the gap between the palatal side of the base and the palatal mucosa, allowing water to flow smoothly into the gap between the palatal mucosa and the base, reducing food residue. The two openings on the base of the maxillary fixed spiral expander on one side can be used for cleaning, reducing problems such as blocked openings that prevent proper cleaning. Using the irrigator head to clean the gap between the palatal mucosa and the base of the maxillary fixed spiral expander effectively reduces oral problems caused by food residue in this gap, maintaining a healthy oral environment.

[0038] The beneficial effects of this invention are as follows:

[0039] 1. The opening in the base of the maxillary fixed spiral expander does not reduce the effect of expander treatment.

[0040] 2. During maxillary expansion treatment, the gap between the palatal mucosa and the base of the maxillary fixed spiral expander is opened, reducing oral problems caused by inability to clean or lack of effective cleaning methods.

[0041] 3. The use of annular openings allows water to diffuse in all directions, improving cleaning efficiency.

[0042] 4. It can be combined with a water flosser to maintain the water flosser's function of cleaning between teeth and also to increase the cleaning of the palatal mucosa and the gap between the base of the maxillary fixed spiral expander, thereby improving the oral cleaning efficiency of patients undergoing maxillary expansion treatment.

[0043] 5. The addition of metal wires inside the tube wall provides a more flexible and shape-adjustable water outlet tube than conventional water flosser heads, offering personalized rinsing options for patients with different needs.

[0044] 6. The structure is reasonably designed, with minimal foreign body sensation, and it is easy to fix to the base opening of the maxillary fixation expander.

[0045] 7. The device is simple and easy to manufacture.

[0046] Meanwhile, a soft rubber ball is added to the tip of the irrigator head to reduce the foreign body sensation and irritation experienced by patients, thereby improving the efficiency of use. Attached Figure Description

Detailed Implementation

[0054] The preferred embodiments of the present invention will now be described in detail with reference to the figures, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0055] like Figure 1 As shown, a flushing assembly for a maxillary fixed spiral expander base includes a flushing head for flushing the maxillary fixed spiral expander base 18 by inserting it into the opening 20 of the maxillary fixed spiral expander base, and an opening device for opening the maxillary fixed spiral expander base 18.

[0056] The flushing head includes a flushing head 4, a water outlet 3, a water outlet pipe 5, a water outlet tube 6, and a metal wire inside the pipe wall 7.

[0057] The rinsing head 4 is a cone-shaped body with a bottom larger than the top. The rinsing head 4 has an outer surface that matches the opening 20 of the maxillary fixed spiral expander base so that it can be inserted and fitted with the maxillary fixed spiral expander base 18. After the rinsing head is inserted into the opening 20 of the maxillary fixed spiral expander base, the outer surface of the rinsing head inside the base corresponds to the shape of the opening of the maxillary fixed spiral expander base, so that the water outlet 3 of the rinsing head can enter the gap between the base and the palatal mucosa when it is inserted into the maxillary fixed spiral expander base 18.

[0058] Outlet 3: Outlets 3 are evenly distributed around the end of the rinsing head 4 and are connected to the water outlet pipe 6. The water outlet 3 is directed towards the rinsing gap between the opening 20 of the maxillary fixed spiral expander base and the palatal mucosa.

[0059] Water outlet pipe 5: Connected to the bottom of the flushing head 4, it is a flexible material pipe that is easy to bend;

[0060] Water outlet pipe 6: a hollow pipe installed inside water outlet pipe 5;

[0061] Metal wire 7 inside the pipe wall: embedded between the pipe wall of the water outlet pipe 6 and the water outlet pipe;

[0062] Opening: The opening 20 of the maxillary fixed spiral expander base 18 is machined on the maxillary fixed spiral expander base and is located between the metal wires inside the tube wall of the maxillary fixed spiral expander base. The two maxillary fixed spiral expander base openings 20 in the single maxillary fixed spiral expander base 18 are located on the palatal side of the deciduous canine area and the area from the deciduous molar to the first molar in the mouth. The gap between the maxillary fixed spiral expander base opening 20 and the palatal mucosa is the rinsing gap. The gap between the palatal side of the maxillary fixed spiral expander base opening 20 and the palatal mucosa is the fixed gap. The fixed gap is used for the entry of the rinsing head. The rinsing gap is used for rinsing the opening. The width of the rinsing gap is greater than that of the fixed gap. During rinsing, the water flow enters the fixed gap from the rinsing gap.

[0063] Preferably, the flushing head 4 is made of hard plastic, and the top of the flushing head 4 is provided with a solid soft rubber ball head 2. A ring of protrusions at the junction of the soft rubber ball head 2 and the hard plastic forms the outermost flange 1 of the hard head end of the flusher. The water outlet 3 is located slightly towards the water outlet pipe end of the outermost flange 1 of the hard head end of the flusher.

[0064] Preferably, the rinsing head 4 has an adhesive soft rubber ball head 2 embedded at its tip to reduce the irritation to the palatal mucosa when the rinsing head enters the opening 20 of the maxillary fixation spiral expander base; the diameter of the soft rubber ball head 2 is smaller than the diameter of the most protruding edge 1 of the rigid tip of the rinsing head, and the soft rubber ball head 2 is fixed on the tip of the rinsing head 4 by adhesive bonding inside the rinsing head.

[0065] like Figure 2C As shown, preferably, the aperture opener is divided into a positioning body 15 and a retaining body 16.

[0066] like Figure 2B As shown, the retainer 16 includes: a retaining post base 9, a retaining post 8, a retaining post base functional surface 10, and a retainer palatal suction cup 11, all arranged concentrically.

[0067] Retention post base 9: The lower end of the retention post base 9, away from the retention post 8, is larger than the upper end, which is closer to the retention post 8.

[0068] Retention post 8: Connected above the retention post base 9, retention post 8 is used to fix the positioning body 15 during the base opening molding;

[0069] The functional surface 10 of the retention post base is the outer contour surface of the retention post base 9. The functional surface 10 of the retention post base is a downwardly widening slope. The downwardly widening slope of the functional surface of the retention post base is used to create a certain gap between the opening on the palatal side of the base and the palatal mucosa when the base of the maxillary fixation spiral expander 18 is formed. This gap connects the fixation gap and the rinsing gap, so that when the rinsing head is used at the opening of the base, the water flow can smoothly enter the rinsing gap and the fixation gap from the opening.

[0070] Palatal suction cup 11 for fixation body: connected below the functional surface 10 of the base of the fixation column, used to fix the maxillary spiral expander base 18. During the opening and forming process, the fixation body can be adsorbed at the palatal top of the patient's maxillary model to complete the fixation of the fixation body.

[0071] like Figure 2A As shown, the positioning body 15 includes a positioning body body 12, a positioning body retaining channel 13, and a positioning body functional surface 14.

[0072] The positioning body 12: After the opening and molding of the maxillary fixation spiral expander base 18 is completed, the positioning body is taken out from the opening 20 of the maxillary fixation spiral expander base;

[0073] The positioning body retention channel 13 is a hollow channel located inside the upper end of the positioning body 12. The diameter and depth of the channel correspond to the size and length of the retention post 8 of the cylindrical positioning body 16. The edge of the plane of the retention post base 9 of the positioning body is aligned with the edge of the wall of the positioning body retention channel 13, so that when the base 18 of the maxillary fixation spiral expander is formed, there is a smooth transition between the palatal opening and the lingual opening, without the generation of a stepped plane.

[0074] The positioning body functional surface 14 is formed by the outer contour surface of the upper end of the positioning body fixation channel 13. The positioning body functional surface 14 is a downwardly widening inclined surface. The axial convergence degree of the positioning body functional surface 14 corresponds to the shape of the rinsing head 4. The positioning body functional surface 14 is used for the lingual opening of the base during molding. The shape of the positioning body functional surface 14 corresponds to the shape of the lingual opening of the maxillary fixed spiral expander base 18 and the shape of the rinsing head 4, so that the rinsing head can smoothly enter the opening 20 of the maxillary fixed spiral expander base and maintain a tight fit with the opening 20 of the maxillary fixed spiral expander base.

[0075] Preferably, the palatal opening shape of the maxillary fixation spiral expander base opening 20 corresponds to the size and shape of the functional surface 10 of the retention post base, and the lingual opening shape corresponds to the size and shape of the functional surface 14 of the placement body.

[0076] Preferably, the palatal suction cup 11 of the retainer is circular.

[0077] Preferably, the upper end of the positioning body 15 is a gradually decreasing frustum shape, and the lower end is a cylindrical positioning body part 12. The positioning body part 12 and the positioning body fixing channel 13 are concentrically arranged.

[0078] Preferably, the positioning channel 13 is a hollow cylindrical channel.

[0079] This embodiment also provides a method for opening the irrigation component of the maxillary fixation spiral expander base, including the following steps:

[0080] (1) Place the aperture opener at the opening position on the model for fabricating the maxillary fixed spiral expander 19. The opening position is located in the maxillary bilateral anterior tooth region and the maxillary bilateral deciduous molar or permanent molar region. Use the palatal suction cup 11 on the retainer 16 to adhere to the model for fabricating the maxillary fixed spiral expander 19 before the base 18 of the maxillary fixed spiral expander is molded.

[0081] (2) After adsorption and fixation are completed, the retaining column 8 of the retaining body 16 is fully inserted into the retaining channel 13 of the retaining body 15.

[0082] (3) After fixation, the base 18 of the maxillary fixed spiral expander is filled with glue and molded. After molding, the positioning body 15 is removed and the molded maxillary fixed spiral expander 19 can be removed, thus completing the opening of the base 18 of the maxillary fixed spiral expander.

[0083] Preferably, different numbers of openings can be made on the base 18 of the unilateral maxillary fixation spiral expander.

[0084] Four arc-shaped openings are centrally symmetrical at the head of the irrigator to ensure that the irrigating water flow is evenly distributed to the gap between the base and the palatal mucosa;

[0085] The protruding edge 1 of the rigid end of the flushing device has a circular structure, which fits and tightly wraps around the soft rubber ball head 2; the protruding edge 1 of the rigid end of the flushing device is used to fix and limit the deformation of the soft rubber ball head 2, while facilitating access to the opening of the base.

[0086] The soft rubber ball head 2 is approximately spherical in shape and fits into the head end of the rinsing head 4. Its diameter is below the most protruding edge 1 of the hard head of the rinsing device and is bonded and fixed to the rinsing head 4. The soft rubber ball head 2 is used to reduce the impact force on the palatal mucosa when the rinsing head enters the base opening.

[0087] The water outlet 3 consists of four small arc-shaped openings surrounding the most protruding edge 1 of the rigid head of the irrigator. Its shape presents a discontinuous ring on the irrigator head. The water outlet is used to guide the direction of water flow and has the function of increasing water pressure in order to improve the efficiency of the irrigator head in rinsing the gap between the base and the palatal mucosa.

[0088] The flushing head 4 is approximately conical in shape, with a larger bottom and a smaller head. The internal hollow shape is similar to the external shape. A soft rubber ball head 2 is attached to the head end. There are four water outlets 3 around the soft rubber ball head 2. The bottom is connected to the water outlet pipe 5, and the bottom is attached to the metal wire 7 inside the pipe wall. The flushing head 4 is used to enter the opening 20 of the base of the maxillary fixation spiral expander. Its narrow shape can increase the water pressure before the water flows to the water outlet.

[0089] The water outlet pipe 5 is attached to the bottom of the rinsing head 4. It is hollow in shape and easy for patients to hold when using it. The pipe wall is embedded with a metal wire 7. The water outlet pipe 5 is used to guide the water flow to the rinsing head and can be bent into any shape for use by patients with different conditions.

[0090] The metal wire 7 inside the pipe wall is embedded in the pipe wall of the water outlet pipe 5. Its shape is parallel to the water outlet pipe 5, and its diameter is slightly smaller than the pipe wall of the water outlet pipe 5. It is used to bend and fix the shape of the water outlet pipe 5 when the patient uses the irrigator, so as to facilitate the patient's use.

[0091] As a preferred embodiment, the soft rubber ball head 2 is made of silicone balls with a diameter ranging from 1.0 to 2.5 mm. The head end of the rinsing head 4 has a semi-spherical concave shape. The diameter of the soft rubber ball head 2 enters the concave part of the head end of the rinsing head 4 and is slightly lower than the most protruding edge 1 of the hard head end of the rinsing device, thereby fixing the soft rubber ball head 2.

[0092] As a preferred embodiment, the width of the water outlet 3 is 0-1mm, and it is a hollow opening that connects to the hollow interior of the flushing head 4, forming an arc around the most protruding edge 1 of the rigid head of the flusher.

[0093] As a preferred embodiment, the rinsing head 4 is made of rigid polyvinyl chloride (PVC), polypropylene (PP) or acrylic (PMMA) material, with a head diameter of approximately 3.0-4.0 mm and a bottom diameter of approximately 6.0-8.0 mm.

[0094] As a preferred embodiment, the water outlet pipe 5 is a hollow tubular shape with an outer diameter of 6.0-8.0 mm and an inner diameter of 3.0-4.0 mm. It is usually made of soft polyvinyl chloride (PVC) and metal wire, and one end is attached to the bottom of the flushing head 4.

[0095] As a preferred embodiment, the water outlet pipe 6 is a tubular shape with a diameter ranging from 3.0 to 4.0 mm, used for the passage of water.

[0096] As a preferred embodiment, the metal wire 7 inside the pipe wall is a straight metal wire with a diameter of 0.7-1.5mm, used to shape the form of the water outlet pipe.

[0097] The base 9 of the retaining post is a circle that is slightly larger than the retaining post and forms a concentric circle with the retaining post.

[0098] The retaining post base functional surface 10 is a downwardly widening inclined surface connected to the upper plane of the retaining post base 9. The height of the retaining post base functional surface 10 and the downward widening are used to create a certain transition gap between the base and the palatal mucosa when the base is formed. This is referred to as the flushing gap. This gap allows the water flow when the flushing head enters the base opening to flow smoothly from the opening into the flushing gap and fixing gap between the base and the palatal mucosa.

[0099] The palatal suction cup 11 of the retainer is a centrally symmetrical circle and is connected to the retainer base 9. It is used to attach the retainer to the model during the base to fix the retainer and achieve the purpose of completing the base to punch the hole.

[0100] The positioning body 12 is a cylindrical structure of a certain length, used to remove the positioning body from the opening of the base after the base is formed.

[0101] The positioning channel 13 is a hollow cylindrical channel. The hollow channel is inside the positioning body 12. The size and depth of the positioning channel correspond to the size and length of the positioning column of the positioning body, and are used to fix the base during molding.

[0102] The axial convergence degree of the functional surface 14 of the in-place body corresponds to the shape of the head end of the flusher head. It is used for the tongue opening of the base during molding, so that the tongue opening of the base, the functional surface 14 of the in-place body, and the shape of the outlet 3 of the flusher head away from the ball end are equal, so that the flusher head can smoothly enter the opening and maintain a certain degree of tightness.

[0103] As a preferred embodiment, the diameter of the retaining post 8 is 1-2 mm, and it is a solid cylinder connected to the retaining post base 9, which is made of stainless steel with high yield strength and corrosion resistance.

[0104] As a preferred embodiment, the retaining post base 9 and the retaining post 8 are manufactured as a single unit, made of the same material, and its outer diameter is slightly larger than that of the retaining post.

[0105] As a preferred embodiment, the material of the functional surface 10 of the retaining post base is the same as that of the retaining post 8, and its bottom diameter is slightly larger than the diameter of the upper plane of the retaining post base 9, with a reference value of 1-3mm for the excess.

[0106] As a preferred embodiment, the palatal suction cup 11 of the retainer is a flat vacuum suction cup made of PVC or TPE material. The diameter of the suction cup should be slightly larger than the bottom diameter of the functional surface of the retainer base, and the difference should be 2-4 mm.

[0107] As a preferred embodiment, the positioning body 12 is made of the same stainless steel material as the retention post 8, and its length should preferably be 1-2 cm longer than the maxillary expander base, so as to facilitate the removal of the positioning body 15 after the base is molded.

[0108] As a preferred embodiment, the material of the positioning channel 13 is the same as that of the positioning body 12, and the size of the positioning channel is the same as that of the positioning post 8.

[0109] As a preferred embodiment, the material of the positioning body functional surface 14 is the same as that of the retaining column 8, and a frustum-shaped axial surface with a small opening and a large bottom is formed by machining the outer circle, with the bottom diameter being the same as the diameter of the positioning body part 12.

[0110] This device can be used by first obtaining a dental model, then making an appropriate-sized hole in the irrigator head when fabricating the maxillary fixed expander base on the model, and finally wearing the expander into the patient's mouth for daily use of the irrigator head.

[0111] like Figure 3B As shown, before using this device, the opening tool paired with the irrigator head needs to be used to open the base 18 of the maxillary fixed spiral expander. The palatal suction cup of the retention body is attached to the model of the maxillary expander made on the patient before the base is molded. After attachment and retention are completed, the placement body is used to ensure the retention post is fully inserted into the placement body's retention channel before the base is molded. After molding, the placement body is removed, and then the molded maxillary expander and base can be taken out, completing the opening of the maxillary expander base. This method allows the irrigator head opening tool to make two openings in the maxillary expander base, enabling cleaning from one opening to another opening on the same side of the base.

[0112] like Figure 3A As shown, patients undergoing maxillary expansion therapy complete the expansion treatment by rotating the spiral expander 21. When using this device, the tip of the irrigator head is inserted into the opening of the maxillary fixed spiral expander base 18, and then pressed down to be located at the opening 20 of the maxillary fixed spiral expander base. At this time, the water outlet is located in the gap between the maxillary fixed spiral expander base 18 and the palatal mucosa. The sprayed water can diffuse outwards through the outlet into the gap between the maxillary fixed spiral expander base 18 and the palatal mucosa 24. The water flow cleans the gap between the base and the palatal mucosa, reducing food residue residue. The irrigator head's design, with a large base and small opening, facilitates entry into the oral cavity and into the opening of the maxillary expander base.

[0113] The rinsing head is comfortable to use, provides good cleaning, and is easy to use, improving the cleaning efficiency during maxillary expansion treatment.

[0114] This method utilizes a maxillary fixed spiral expander base 18 with perforations. Water flows from the rinsing gap on the palatal side of the base to the surrounding areas and then to the fixed gap beneath the base. This effectively removes food debris from both the rinsing and fixed gaps. Simultaneously, the two perforations on the same side of the base reduce the likelihood of food clogging the perforations and hindering cleaning. This effectively reduces oral problems caused by the inability to clean the space between the base and the palatal mucosa.

[0115] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although modifications are made to the technical solutions described in the foregoing embodiments, or equivalent substitutions are made to some of the technical features, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
