Description

Technical Field

[0001] The invention belongs to the technical field of oral orthodontic tooth correction, and in particular relates to a method for quickly making an occlusal pad. Background Art

[0002] Bracketless invisible braces need to be removed when eating. For cases of malocclusion or other occlusal interference, the interference between the upper and lower teeth is difficult to eliminate due to the existence of occlusal movement. To solve this problem, occlusal pads are made on the teeth before the patient wears the braces, but the production is relatively complicated, and the shape of the occlusal pad must be trimmed during the correction process, which will undoubtedly have an adverse effect on the fit between the invisible braces and the tooth surface; another type of occlusal pad is composed of denture base material and a clasp made of bent stainless steel wire. It is large in size and less comfortable, and can only be used when eating. At other times, patients only wear invisible braces The locking relationship between the upper and lower jaws cannot be released, and the teeth cannot move to their normal positions. Therefore, in the prior art, the orthodontist can choose to make an occlusal pad directly on the invisible braces, and use a self-curing denture base material to line the occlusal surface of the invisible braces. After the material is completely cured, it is ground to an appropriate height, and the occlusal pad is completed. However, in the invisible braces technology without brackets, the teeth move slowly, and only one invisible braces with an occlusal pad usually cannot completely eliminate the occlusal interference. Patients often need multiple pairs of invisible braces with occlusal pads, and wear and replace them according to the doctor's orders to achieve the purpose of eliminating the occlusal interference.

[0003] However, in the bracketless invisible orthodontic technology, patients often need to replace a new pair of braces every 2 weeks. For patients who need to make occlusal pads, they need to go to the hospital for a follow-up visit every 2 weeks to make the occlusal pads. The conventional follow-up interval is 8-12 weeks. In this way, the production and wearing of the occlusal pads will greatly shorten the follow-up interval, causing inconvenience to patients, and making it impossible to reflect the significant advantage of bracketless invisible orthodontic treatment, "reducing the number of follow-up visits". In addition, the conventional process for making this occlusal pad in clinical practice is to add the prepared self-curing denture base material to the occlusal surface of each pair of invisible braces that need to make occlusal pads, trim and shape it, wait for it to solidify, and then wear each pair of invisible braces with occlusal pads into the patient's mouth for adjustment and grinding. In this way, each pair of invisible braces needs to be tried and adjusted repeatedly when making occlusal pads, which will complicate the occlusal pad production process, greatly extend the chairside operation time, and increase discomfort for patients. Summary of the invention

[0004] The object of the present invention is to provide a method for manufacturing an occlusal pad to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for making an occlusal pad, comprising an impression tray, a silicone rubber impression, an occlusal pad and an invisible orthodontic appliance required in the making method, and the specific steps are as follows:

[0006] Step 1: Grind the occlusal surface of the posterior teeth of the bracketless invisible braces. Take the mandibular parts of multiple invisible braces that need to be made into occlusal pads and opened to bite, and use a low-speed grinder to roughen the occlusal surface of the posterior teeth of the mandibular invisible braces.

[0007] Step 2: Mix the self-curing denture base material;

[0008] Step 3: Make the occlusal pad. The production method is as follows

[0009] S1: Take the first pair of invisible braces that need to be made into occlusal pads and open the bite, place the prepared self-curing denture base material on the roughened occlusal surface of the invisible braces, and trim and shape it;

[0010] S2: When the self-curing denture base material is completely solidified, put the invisible braces back into the patient's mouth, and also put the maxillary invisible braces in, and observe the degree of bite opening. If the upper and lower teeth are not separated, it means that the thickness of the self-curing material lining the occlusal surface of the invisible braces is insufficient, that is, the height of the occlusal pad is insufficient. It is necessary to mix the self-curing material again according to the above steps and add it to the occlusal surface of the invisible braces;

[0011] S3: When the upper and lower teeth are separated after the invisible braces are inserted, the production is successful;

[0012] Step 4: Take a silicone rubber impression, put the mandibular invisible braces with occlusal pad and the untreated maxillary invisible braces into the patient's mouth, observe the fit of the invisible braces to the tooth surface, and the proper distance between the upper and lower teeth, take an impression tray of appropriate size, and use the silicone rubber impression technology to make a mandibular silicone rubber impression. In this way, the height and shape of the occlusal pad of the first invisible braces with occlusal pad are recorded by the silicone rubber impression;

[0013] Step 5: To make occlusal pads for multiple sets of invisible braces, take the invisible braces that need occlusal pads in turn, roughen the occlusal surface of the invisible braces with a low-speed grinder, mix an appropriate amount of self-curing denture base material, and line the occlusal surface of the invisible braces. After rough trimming and shaping, place the invisible braces into the obtained silicone rubber impression, squeeze out the excess self-curing denture base material before the material solidifies and remove it, and after the remaining material is completely solidified, the occlusal pad of this set of invisible braces is completed, take out the invisible braces with the occlusal pad, and use the silicone rubber impression to make occlusal pads on multiple sets of invisible braces according to this step.

[0014] As a preferred technical solution in the present invention, the specific steps in step 2 are to take an appropriate amount of self-curing denture base powder into a rubber cup, then take an appropriate amount of denture base water, with a powder-liquid ratio of 1.0g:0.5ml, and stir until the sticky stage.

[0015] As a preferred technical solution in the present invention, in S2, the specific parameter for observing the degree of bite opening is that the distance between the upper and lower teeth should be controlled within 2 mm. If it exceeds 2 mm, a low-speed grinder is required to grind off the excess self-curing material on the orthodontic appliance in small amounts and multiple times until the upper and lower teeth are separated and the distance is within 2 mm, while ensuring uniform contact between the bilateral posterior teeth.

[0016] As a preferred technical solution in the present invention, in step five, the height of the occlusal pads of subsequent multiple pairs of invisible braces is consistent with the height of the occlusal pads of the first pair of invisible braces with occlusal pads, there is no need to adjust the occlusal pads, and the degree of bite opening meets the orthodontic clinical requirements.

[0017] As a preferred technical solution in the present invention, the longitudinal section of the impression tray is a "Y"-shaped structure, and the inner surface of the impression tray is in contact with the bottom end surface of the silicone rubber impression.

[0018] As a preferred technical solution in the present invention, the occlusal pad is combined with the invisible braces to form an invisible braces with a self-curing denture base material.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention adopts a method of directly making an occlusal pad on an invisible brace appliance with a self-curing denture base material, and adopts silicone rubber impression technology. When the patient returns for a follow-up visit, the occlusal pad can be simply and quickly made on multiple braces without the need for repeated trial wearing and adjustment, thus saving chairside operation time and, more importantly, extending the follow-up interval of the patient, providing great convenience for the patient.

[0027] Step 1: Grind the occlusal surface of the posterior teeth area of ​​the bracketless invisible braces 32, take the mandibular parts of multiple pairs of invisible braces that need to be made into occlusal pads and open the bite, and use a low-speed grinder to roughen the occlusal surface of the posterior teeth area of ​​the mandibular invisible braces;

[0028] Step 2: Mix the self-curing denture base material;

[0029] Step 3: Make the occlusal pad 31, the making method is as follows

[0030] S1: Take the first pair of invisible braces 32 for which an occlusal pad is to be made, open the occlusal surface, and place the prepared self-curing denture base material on the roughened occlusal surface of the invisible braces 32 to shape it;

[0031] S2: When the self-curing denture base material is completely cured, the invisible appliance 32 is put back into the patient's mouth, and the maxillary invisible appliance is also put in, and the degree of occlusal opening is observed. If the upper and lower teeth are not separated, it means that the thickness of the self-curing material lining the occlusal surface of the invisible appliance 32 is insufficient, that is, the height of the occlusal pad 31 is insufficient, and the self-curing material needs to be mixed again according to the above steps and added to the occlusal surface of the invisible appliance 32;

[0032] S3: When the upper and lower teeth are separated after the invisible braces 32 are put in, the manufacturing is successful;

[0033] Step 4: Take the silicone rubber impression 2, wear the mandibular invisible appliance 32 with the occlusal pad 31 and the untreated maxillary invisible appliance into the patient's mouth, observe whether the upper and lower invisible appliances fit the tooth surface, and whether the upper and lower teeth are separated by an appropriate distance, take the impression tray 1 of suitable size, use the silicone rubber impression technology to make the mandibular silicone rubber impression 2, and adopt the method of making the occlusal pad 31 directly on the invisible appliance 32 with a self-curing denture base material. At the same time, the silicone rubber impression 2 technology can be used to make occlusal pads 31 on multiple appliances during the patient's follow-up visit, without the need for repeated trial wearing and adjustment, saving chairside operation time, and more importantly, extending the follow-up interval of the patient, providing great convenience for the patient;

[0034] Step 5: To prepare the occlusal pads 31 for multiple pairs of invisible braces, take the invisible braces 32 that need to be prepared with the occlusal pads 31 in turn, use a low-speed grinder to roughen the occlusal surface of the invisible braces 32, mix an appropriate amount of self-curing denture base material, and line the occlusal surface of the invisible braces 32.

[0036] In this embodiment, in S2, the specific parameter for observing the degree of bite opening is that the distance between the upper and lower teeth should be controlled within 2 mm. If it exceeds 2 mm, a low-speed grinder is required to grind off the excess self-curing material on the orthodontic appliance in small amounts and multiple times until the upper and lower teeth are separated and the distance between them is within 2 mm. After debugging is completed, proceed to the next step, while ensuring uniform contact between the bilateral posterior teeth.

[0037] In this embodiment, in step five, the height of the occlusal pads 31 of the subsequent multiple pairs of invisible braces 32 is consistent with the height of the occlusal pads 31 of the first pair of invisible braces with occlusal pads 31, the height of the occlusal pads of the subsequent multiple pairs of invisible braces does not need to be adjusted again, and the degree of bite opening meets the orthodontic clinical requirements.

[0038] In this embodiment, the longitudinal section of the impression tray 1 is a "Y"-shaped structure, and the inner surface of the impression tray 1 is fitted with the bottom end surface of the silicone rubber impression 2. When making the silicone rubber impression 2, the silicone rubber impression 2 material is placed in the impression tray 1, and the silicone rubber impression 2 material can be shaped and placed in the oral cavity together with the impression tray 1. After the silicone rubber impression 2 material solidifies, it is taken out together with the impression tray 1, and the height and shape of the occlusal pad 31 of the first pair of invisible braces 32 with occlusal pad 31 can be recorded, and the silicone rubber impression 2 is completed.
