Description

Technical Field

[0001] The present invention relates to the field of oral medical equipment, and in particular to an oral implant restoration opening degree measuring device and a use method thereof. Background Art

[0002] In the field of oral implant restoration, with the continuous development of dental implant technology, more and more patients choose to restore the function and appearance of missing teeth through dental implant restoration technology. Oral implant restoration is a treatment plan that replaces missing teeth by implanting artificial tooth roots into the alveolar bone and then connecting dentures through implants. This method can not only restore chewing function, but also significantly improve aesthetics. In order to ensure the stability and functionality of the implant, preoperative evaluation is crucial. Before the operation, detailed measurements of the patient's oral opening, tooth root pits and other key parts are required to provide a scientific basis for personalized restoration plans.

[0003] The measurement of oral opening is very important in the process of implant restoration. Oral implant surgery requires the patient to open his mouth at a certain angle to ensure that the doctor can smoothly operate and use the implant instruments. If the patient's mouth opening is insufficient, it may increase the difficulty of the operation and even affect the implantation angle and position. Therefore, accurate measurement of the patient's mouth opening angle and mouth opening in the posterior teeth before surgery can help the doctor evaluate the patient's mouth opening ability and provide a reference for surgical design, thereby ensuring the smooth progress of the implant surgery.

[0004] In addition, the measurement of the root pit is also an important part of implant restoration. During the implantation process after tooth extraction, the depth and width of the root pit determine the selection and size of the implant. Accurate root pit measurement not only affects the stability of the implant, but is also directly related to the success of the implant surgery. Improper measurement may cause the position of the implant to shift or the implant to be unstable. Therefore, accurate measurement of the root pit before surgery can help doctors accurately plan the implant placement plan and ensure the long-term stability and effect of implant restoration.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "front end", "back end", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0019] In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0020] This embodiment provides a device for measuring the degree of opening of an oral implant restoration. Figures 1 to 15As shown, it includes two positioning trays 1, two positioning trays 1 detachably connected to an angle measuring ruler 4, and the ends of the two positioning trays 1 are connected by a posterior tooth area measuring ruler 11; a fixing component 2 and a first slide rail 12 are provided in the positioning tray 1, the fixing component 2 is used to fix the positioning tray 1 and the teeth, and the first slide rail 12 is slidably connected to the root fossa measuring mechanism 3. The positioning tray 1 is made of memory alloy. At normal human body temperature, it can fit the teeth of different patients and has high adaptability. Through the fixation of the fixing component 2, it can be stabilized on the upper and lower teeth during the measurement process, thereby ensuring the measurement accuracy. The angle measuring ruler 4 is connected to the front part of the patient's upper and lower front teeth to measure the opening angle; the posterior tooth area measuring ruler 11 connects the upper and lower parts of the positioning tray 1 to measure the opening degree of the posterior tooth area. The root fossa measuring mechanism 3 is used to measure the depth and width of the root fossa exposed after the patient's tooth extraction.

[0021] Furthermore, the fixing assembly 2 includes a posterior teeth fixing band 21 and an anterior teeth fixing plate 22; the posterior teeth fixing band 21 connects the two ends of the positioning tray 1, and the anterior teeth fixing plate 22 is connected to the positioning tray 1 through two elastic fixing ropes 23 in the horizontal direction. Through a principle similar to dental floss, the posterior teeth fixing band 21 and the two elastic fixing ropes 23 can be inserted into the gap between teeth and provide a fixing effect. At the same time, the memory alloy material of the positioning tray 1 can also assist in a certain fixing effect through fitting and deformation. Therefore, through the joint action of the posterior teeth fixing band 21, the anterior teeth fixing plate 22 and the two elastic fixing ropes 23, the device can be effectively installed and stabilized on the upper and lower teeth.

[0022] During specific use, taking into account the particularity of the use positions of the posterior teeth fixing belt 21 and the two elastic fixing ropes 23, the material of the device is generally recycled after one-time use; if it needs to be reused due to special circumstances, it should be thoroughly cleaned and disinfected before reuse. At this time, the posterior teeth fixing belt 21 and the two elastic fixing ropes 23 should be disassembled and replaced, and they can be replaced and fixed by simply threading and tying knots. Obviously, other conventional replacement and fixing methods can also be used in other embodiments.

[0023] Furthermore, the positioning bracket 1 is provided with a slot 13 corresponding to the connecting block 41 at the end of the angle measuring ruler 4. This allows the angle measuring ruler 4 to be more firmly connected to the positioning bracket 1, reducing the possibility of loosening or displacement during the measurement process, thereby effectively improving the stability of angle measurement.

[0024] Furthermore, the posterior teeth measuring ruler 11 includes a ruler body and a ruler strip rolled in the ruler body, the ruler body is arranged outside one of the positioning brackets 1, and the outer end of the ruler strip is connected to the edge of the other positioning bracket 1. The posterior teeth opening degree can be measured. The ruler strip can be freely extended and retracted during the measurement process to adapt to the posterior teeth width of different patients, and its rolled structure is convenient for storage when not in use.

[0025] Embodiment 2: Based on Embodiment 1, Embodiment 2 provides a specific structure of a tooth root socket measuring mechanism 3, such as Figure 7 and Figure 8 As shown, the tooth root socket measurement mechanism 3 includes an adjustment rod 31, a platform 32, a telescopic rod 33 and a multi-layer width measurement assembly 34; one end of the adjustment rod 31 is slidably connected to the first slide rail 12, and the other end is connected to the side of the platform 32; one end of the telescopic rod 33 is connected to the bottom surface of the platform 32, and the other end is connected to the multi-layer width measurement assembly 34. The adjustment rod 31 can flexibly adjust the position of the tooth root socket measurement mechanism 3 through the first slide rail 12. At the same time, the adjustment rod 31 is made of a metal material that is easy to bend under force and is stable and fixed. The measurement personnel can use the platform 32 to adjust the axial angle of the telescopic rod 33 so that it can accurately align with the tooth root socket after tooth extraction. The telescopic rod 33 can be adjusted to make the multi-layer width measurement assembly 34 accurately contact the bottom of the tooth root socket, and the elongation of the telescopic rod 33 can reflect the depth of the tooth root socket. The multi-layer width measurement assembly 34 is designed in layers and independently controlled, and can comprehensively measure the different widths of multiple depths of the tooth root socket, thereby improving the accuracy and comprehensiveness of the measurement.

[0026] Furthermore, if Figures 9 to 15 As shown, the width measuring assembly 34 includes a driving disc 341, a plurality of measuring links 342 evenly and symmetrically arranged, and a second slide rail 343 corresponding to the plurality of measuring links 342; the middle portion of the driving disc 341 is rotatably connected to the telescopic rod 33, one end of the plurality of measuring links 342 is evenly rotatably connected to the outside of the driving disc 341, and the other end is slidably connected to the second slide rail 343, and the second slide rail 343 is provided with a plurality of sliders 345 corresponding to the plurality of measuring links 342. The rotation of the driving disc 341 drives the plurality of measuring links 342 to move synchronously, so that the measuring links 342 can be unfolded and measure the width. Specifically, as shown in FIG. Fig. 9 In order to clearly illustrate the principle of contraction and expansion of the width measuring component 34, the multi-layer width measuring components 34 in the figure are contracted in sequence from bottom to top according to the number of layers.

[0027] Further, the measuring link 342 includes a movable curved rod 3421 and a push rod 3422. One end of the movable curved rod 3421 is rotatably connected to the outside of the driving disk 341, and the other end is rotatably connected to the push rod 3422. The push rod 3422 is slidably connected to the second slide rail 343, and the push rod 3422 abuts against the corresponding slider 345. The push rod 3422 is connected to the movable curved rod 3421 and slidably connected to the second slide rail 343. The rotation of the driving disk 341 drives the movable curved rod 3421 to move, thereby enabling the push rod 3422 to move smoothly along the second slide rail 343, thereby realizing the contraction and expansion of the measuring link 342, and pushing the slider 345 to slide on the second slide rail 343.

[0028] Specifically, before measurement, the measuring link 342 is in a retracted state, and the slider 345 abuts against the pushing rod 3422; after the root socket measuring mechanism 3 enters the root socket to be measured, the motor drives the measuring link 342 to expand, and the pushing rod 3422 pushes the slider 345. After the measuring link 342 abuts against the inner edge of the root socket and is blocked, the motor drives the measuring link 342 to retract; thereafter, the telescopic rod 33 retracts, and the root socket measuring mechanism 3 withdraws from the root socket to be measured; at this time, the distance that the slider 345 is pushed is the expanded length of the measuring link 342, and this expanded length plus the length of the outer side of the measuring link 342 from the axis of the telescopic rod 33 when the measuring link 342 is retracted can more accurately obtain the measured width radius of the root socket to be measured.

[0029] Working steps 1. Install the positioning bracket and fixing components The two positioning brackets 1 are respectively attached to the maxillary teeth and the mandibular teeth, and the posterior teeth fixing belt 21 is inserted into the gap between the posterior teeth, the anterior teeth fixing plate 22 is placed behind the anterior teeth, and the two elastic fixing ropes 23 are inserted into the gap between the anterior teeth. The fitting of the memory alloy material and the fixing function of the fixing component 2 are utilized to ensure that the positioning bracket 1 is firmly installed on the patient's upper and lower teeth, thereby ensuring the measurement accuracy.

[0030] 2. Connect the angle measuring ruler The angle measuring ruler 4 is connected to the two positioning brackets 1. The angle measuring ruler 4 is firmly combined with the card slot 13 through the connecting block 41 to reduce looseness or displacement during the measurement process, thereby improving the stability of the measurement. This step is used to measure the opening angle of the person being measured.

[0031] 3. Obtain the opening angle and opening degree of the posterior teeth The person being measured opens his mouth as required and maintains the opening width, and the measuring personnel obtain the opening angle and the opening degree of the posterior teeth area of ​​the person being measured through the angle measuring ruler 4 and the posterior teeth area measuring ruler 11. The posterior teeth area measuring ruler 11 can accurately measure the opening degree of the posterior teeth area by connecting the upper and lower positioning brackets 1.

[0032] 4. Adjust the tooth root socket measurement mechanism and perform measurement The measurement personnel adjust the adjustment rod 31 to align the tooth root socket measurement mechanism 3 with the tooth root socket corresponding to the tooth extracted by the measured person, and then perform the measurement. The specific measurement steps include: (1) Adjust the adjustment lever Adjust the adjusting rod 31, and the tooth root socket measuring mechanism 3 is axially aligned with the tooth root socket to be measured. The adjusting rod 31 is slidably connected to the first slide rail 12, and the measuring position can be flexibly adjusted to ensure that the tooth root socket measuring mechanism 3 can accurately align with the tooth root socket to be measured.

[0033] (2) Extend the telescopic rod The telescopic rod 33 is extended until it touches the bottom of the tooth root pit to be measured. One end of the telescopic rod 33 is connected to the bottom surface of the platform 32, and the other end is connected to the multi-layer width measurement component 34. The multi-layer width measurement component 34 can accurately contact the bottom of the tooth root pit through telescopic adjustment, and the depth of the tooth root pit is recorded by the extension of the telescopic rod.

[0034] (3) Measuring the width of the tooth root pit The measuring link 342 is in a retracted state, and the slider 345 abuts against the pushing rod 3422; after the root socket measuring mechanism 3 enters the root socket to be measured, the motor drives the measuring link 342 to expand, and the pushing rod 3422 pushes the slider 345. After the measuring link 342 abuts against the inner edge of the root socket and is blocked, the motor drives the measuring link 342 to retract; then, the telescopic rod 33 retracts, and the root socket measuring mechanism 3 withdraws from the root socket to be measured; at this time, the distance that the slider 345 is pushed is the expanded length of the measuring link 342, and this expanded length plus the length of the outer side of the measuring link 342 from the axis of the telescopic rod 33 when the measuring link 342 is retracted can more accurately obtain the measured width radius of the root socket to be measured.

[0035] (4) Disassembly After the measurement is completed, the measuring device is gradually disassembled. First, the angle measuring ruler 4 is removed, then the posterior tooth area fixing belt 21 and the two elastic fixing ropes 23 are removed, and finally the positioning bracket 1 is removed.

[0036] Specific application cases: In a dental clinic, a dentist needs to perform an evaluation for a patient before an oral implant restoration surgery. The main purpose is to measure the patient's mouth opening and the depth and width of the root pit after tooth extraction in order to determine the best implant restoration plan. At this time, the mouth opening measurement device of the present invention can be used, as follows.

[0037] 1. Prepare the device Before use, first ensure that all parts of the oral implant restoration mouth opening measurement device are intact and sterilized.

[0038] 2. Install the positioning bracket The dentist fits the two positioning trays 1 to the patient's upper and lower teeth respectively. The two ends of the positioning trays 1 are inserted into the gaps between the posterior teeth through the posterior teeth fixing belt 21, and then the front teeth fixing plate 22 is placed behind the front teeth and inserted into the gaps between the front teeth through two elastic fixing ropes 23, so that the positioning trays 1 are firmly fixed on the upper and lower teeth.

[0039] 3. Connect the angle measuring ruler The dentist connects the angle measuring ruler 4 to the two positioning brackets 1 so that the connecting block 41 is firmly combined with the clamping slot 13, thereby being able to measure the opening angle of the patient.

[0040] 4. Measure the opening The dentist asks the patient to open his mouth and maintain the opening width as required, and then measures the patient's opening angle and the opening degree of the posterior teeth area by using the angle measuring ruler 4 and the posterior teeth area measuring ruler 11 .

[0041] 5. Adjust the tooth root socket measurement mechanism The position of the tooth root socket measuring mechanism 3 is flexibly adjusted by using the adjusting rod 31 so that it is axially aligned with the tooth root socket to be measured. The adjusting rod 31 is slidably connected to the first slide rail 12 to ensure that the tooth root socket measuring mechanism 3 can be correctly aligned with the tooth root socket after tooth extraction.

[0042] 6. Measure the depth and width of the tooth root pit The telescopic rod 33 is extended until it touches the bottom of the tooth root pit, and the extension of the telescopic rod 33 is recorded to reflect the depth of the tooth root pit. At the same time, the measuring link 342 is driven to expand by the motor, and the push rod 3422 pushes the slider 345, so that the measuring link 342 abuts against the inner edge of the tooth root pit and is blocked, and then the motor drives the measuring link 342 to retract. The distance that the slider 345 is pushed is recorded, and this distance is the expanded length of the measuring link 342. When the measuring link 342 is added to the length of the outer side from the axis of the telescopic rod 33 when the measuring link 342 is retracted, the width radius of the tooth root pit can be obtained.

[0043] 7. Data recording and analysis The measured opening angle, the opening degree of the posterior teeth, and the depth and width of the root pit are recorded and analyzed. These data will be used to develop a personalized implant plan to ensure the accuracy and success rate during the operation.

[0044] 8. Disassembly After the measurement is completed, the measuring device is gradually disassembled. First, the angle measuring ruler 4, the posterior tooth area fixing belt 21 and the two elastic fixing ropes 23 are removed, and then the positioning bracket 1 is removed.
