Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a composite occlusal device and a manufacturing method thereof. Background Art

[0002] In the clinical treatment of temporomandibular joint disorders, articular disc displacement is a common and complex pathological condition. Arthroscopic surgery has become an effective minimally invasive intervention, especially for patients with limited mouth opening, locking joints, or chronic pain. The key to postoperative rehabilitation is to maintain the reduction of the articular disc and guide the mandibular movement trajectory back to the physiological pattern to prevent recurrence. Currently, jaw pads or bite plates are commonly used for postoperative adjuvant treatment in clinical practice. They mainly adjust the mandibular position by changing the occlusal relationship, reduce joint load, and promote tissue healing.

[0003] However, traditional jaw supports are mostly static and single-function devices, typically only enabling fixed mandibular advancement without dynamic guidance and graded control of mandibular movement. While they offer some traction, they often apply a large amount of advancement at once, which can easily lead to muscle discomfort, joint pain, and even new functional impairments. This can be particularly problematic during the early postoperative period of tissue sensitivity, leading to poor patient compliance. Summary of the Invention

[0004] Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a composite occlusal device and a method for manufacturing the same, which solves the technical problems in the prior art of using jaw pads or bite plate devices for postoperative auxiliary treatment, such as single function and single-stage traction, which leads to poor compliance of some patients.

[0006] Technical Solution

[0007] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] In a first aspect, the present invention provides a composite occlusal device comprising an upper brace, a lower brace, a stabilizing component, and a correcting component;

[0009] The stabilizing assembly includes an upper stabilizing block fixedly connected to the upper brace and a lower stabilizing block fixedly connected to the lower brace, wherein the upper stabilizing block and the lower stabilizing block form two first occlusal surfaces that cooperate with each other, and when the two first occlusal surfaces occlude with each other, the mandible is protruded forward relative to the upper brace by a first distance to achieve primary distraction of the mandible;

[0010] The correction component includes an upper occlusal pad fixedly connected to the upper braces, and a lower occlusal pad fixedly connected to the lower braces. Two second occlusal surfaces that can cooperate with each other are formed on the upper occlusal pad and the lower occlusal pad. When the two second occlusal surfaces are occluded, the mandible protrudes forward by a second distance relative to the upper braces on the basis of the first distance to achieve secondary traction of the mandible.

[0011] In one technical solution of the present invention, the first occlusal surface corresponding to the lower stabilizing block includes a first guide surface and a second guide surface smoothly connected to each other and arranged at an angle, and the second guide surface protrudes backward relative to the first guide surface.

[0012] In one technical solution of the present invention, the stabilizing component and the correcting component are detachably fixedly connected to the corresponding upper braces and lower braces.

[0013] In one technical solution of the present invention, the stabilization component and the correction component are set to various angles and sizes to form various stabilization levels and correction levels.

[0014] In one technical solution of the present invention, both the stabilizing component and the correcting component are located on the inner side of the teeth.

[0015] In one technical solution of the present invention, a guide groove and a guide protrusion are formed on the upper stabilizing block and the lower stabilizing block respectively; when the upper stabilizing block and the lower stabilizing block are matched, the guide groove and the guide protrusion can cooperate with each other to achieve occlusal positioning of the mandible.

[0016] In one technical solution of the present invention, a composite occlusal device is used as a correction device for arthroscopic disc reduction surgery.

[0017] In a second aspect, the present invention provides a method for manufacturing a composite occlusal device, which is suitable for producing the composite occlusal device in the above technical solution, and the manufacturing method comprises:

[0018] S1: Determine the patient's actual occlusal dynamics;

[0019] S2: Production of composite occlusal devices based on actual occlusal dynamics.

[0020] In one technical solution of the present invention, the actual occlusal dynamics of the patient are determined, specifically by multi-dimensionally integrating diagnostic information from CT, MRI, and a jaw articulator.

[0021] Beneficial effects

[0022] The beneficial effects of the present invention are: the composite occlusal device of the present invention has a stabilizing component including an upper stabilizing block and a lower stabilizing block. When the patient wears the occlusal device of the present invention and closes the lower teeth, the first occlusal surfaces on the upper stabilizing block and the lower stabilizing block will always cooperate with each other, thereby pulling the patient's mandible forward a smaller first distance. In this way, the position of the articular disc can be stabilized after arthroscopic surgery. At the same time, since the first distance will not be too large, it will not cause discomfort to the patient.

[0023] When the patient continues to bite, the two second occlusal surfaces cooperate, and under the traction effect after the two second occlusal surfaces cooperate, the lower occlusal pad will pull the mandible to continue moving forward a second distance. At this time, the upper stabilizing block and the lower stabilizing block are disengaged, and the correction component plays the role of correcting the mandible.

[0024] The stabilizing and correcting components never take effect simultaneously, but rather independently, with the stabilizing component always taking effect first, followed by the correcting component. This allows the mandible to be protruded before correction, reducing discomfort when the correcting component takes effect and improving the correction effect. Because the bite device combines the functions of mandibular stabilization and correction, it is more flexible to use and avoids the high cost and complicated replacement process associated with using two separate devices.

[0047] In order to better explain the present invention, so as to facilitate understanding, the following Figures 1-15 , the present invention is described in detail through specific implementation methods. Figure 1 The orientation is referenced.

[0048] Example 1:

[0049] ReferenceFigures 1-15 The embodiment of the present invention provides a composite occlusal device, comprising an upper brace 1 and a lower brace 2 respectively connected to the patient's upper teeth and lower teeth, as well as a stabilizing component 3 and a correcting component 4; the stabilizing component 3 comprises an upper stabilizing block 31 fixedly connected to the upper brace 1 and a lower stabilizing block 32 fixedly connected to the lower brace 2, and the upper stabilizing block 31 and the lower stabilizing block 32 respectively form first occlusal surfaces 3a that cooperate with each other. When the two first occlusal surfaces 3a occlude with each other, under the action of the inclined surfaces of the two first occlusal surfaces 3a, the mandibular joint is The upper braces 1 are extended a first distance to achieve primary traction of the mandible; the correction component 4 includes an upper occlusal pad 41 fixedly connected to the upper braces 1, and a lower occlusal pad 42 fixedly connected to the lower braces 2, and second occlusal surfaces 4a that can cooperate with each other are respectively formed on the upper occlusal pad 41 and the lower occlusal pad 42. When the two second occlusal surfaces 4a are occluded, under the interaction of the two second occlusal surfaces 4a, the mandible is extended a second distance relative to the upper braces 1 on the basis of the first distance to achieve secondary traction of the mandible.

[0050] In this embodiment, when a patient wears the occlusal device and engages in centric occlusion, the first occlusal surfaces 3a of the upper and lower stabilizing blocks 31, 32 constantly engage with each other, causing the upper stabilizing block 31 to exert a continuous forward thrust on the lower stabilizing block 32, thereby displacing the mandible forward relative to the skull base by a predetermined first distance. This thrust and first distance are set to a value sufficient to maintain the anatomical reduction of the disc-condylar complex after temporomandibular arthroscopy without inducing masticatory muscle spasm or temporomandibular joint pain, thereby reducing the risk of disc redislocation after surgery and improving patient compliance.

[0051] When the patient continues to bite, the two second occlusal surfaces 4a cooperate, and the upper occlusal pad 41 will generate a continuous forward pushing force on the lower occlusal pad 42. Under the traction action after the two second occlusal surfaces 4a cooperate, the lower occlusal pad 42 will pull the mandible to continue to move forward a second distance. At this time, the upper stabilizing block 31 and the lower stabilizing block 32 are disengaged, and the correction component 4 plays the role of correcting the mandible.

[0052] Stabilizing component 3 and correcting component 4 do not activate simultaneously, but always independently, with stabilizing component 3 always taking effect first, followed by correcting component 4. This allows the mandible to be protruded before correction, reducing discomfort when correcting component 4 takes effect, and also improving the correction effect. Because this bite device combines the functions of mandibular stabilization and correction, it is more flexible to use and avoids the high cost and complicated replacement process caused by using two sets of devices.

[0053] Specifically, the upper braces 1 and the lower braces 2 can be made of polymer materials, and the stabilizing component 3 includes an upper stabilizing block 31 fixed to the upper braces 1 and a lower stabilizing block 32 of the lower braces 2. In space, the lower stabilizing block 32 is closer to the front and the upper stabilizing block 31 is closer to the back. Their surfaces are micro-textured to form mutually occlusal surfaces. When the patient closes his lower teeth, the lateral component force generated by the contact between the front end surface of the upper stabilizing block 31 and the rear end surface of the lower stabilizing block 32 can pull the mandible forward by about 2-3 mm, that is, the first distance, which not only meets the forward traction requirement required for postoperative articular disc reduction, but also avoids excessive extension causing muscle spasms or pain. The correction component 4 is realized through the occlusal pad at the rear of the upper braces 1. When the patient bites further, the two second occlusal surfaces 4a cooperate with each other. The second occlusal surface 4a of the upper occlusal pad 41 is the front end surface, and the second occlusal surface 4a of the lower occlusal pad 42 is the rear end surface, so that the lower occlusal pad drives the lower braces and the mandible to slide along the preset trajectory, so that the mandible moves forward 2-4mm on the basis of the original protrusion, that is, the second distance. At this stage, the contact between the upper stabilizing block 31 and the lower stabilizing block 32 will be released, so that the correction force is concentrated on the mandible, avoiding the supporting force of the stabilizing component from interfering with the correction effect.

[0054] In this embodiment, when the patient initially closes the jaw, the mandible slides forward under the action of the occlusal force, resulting in an anterior displacement of 2-3 mm. At this time, the stabilizing assembly 3 provides a certain amount of continuous traction through surface contact. As the occlusal depth increases, the engagement of the lower bite pad 42 with the upper bite pad 41 guides the mandible to undergo additional anterior displacement, at which point the two first occlusal surfaces 3a separate from each other.

[0055] Specifically, the stabilizing components 3 are positioned on the upper and lower braces, corresponding to the wearer's molars. The corrective components 4 are positioned on the upper and lower braces, corresponding to the wearer's incisors. This ensures sufficient spacing between the two components, facilitating the required graded mandibular distraction. Furthermore, the stabilizing components 3 are arranged in two symmetrical groups, while the corrective components 4 are arranged in a single group, located in the middle of the braces.

[0056] Two sets of symmetrical stabilizing components 3 can improve the stability and effectiveness of the device during use. A set of corrective components 4 located in the middle of the braces can reduce the impact of the device on the eating process. The wearer can avoid the impact of the corrective components 4 by eating sideways, thereby improving the wearer's acceptance and comfort of use.

[0057] When stabilizing component 3 is active, the wearer's mandible is not fully closed to the maxilla. For most people, this state is relatively relaxed, and thus helps stabilize the mandible. The fully engaged state, on the other hand, corresponds to the active state of correcting component 4, which is a deliberate action by the wearer.

[0058] And the first occlusal surface 3a on the lower dental brace 2 can be further set as a stepped structure, so that the two first occlusal surfaces 3a have the ability to pull the mandible in multiple stages during the matching process, thereby further improving the flexibility of the device.

[0059] Specifically, referring to Figure 10 and Figure 11 , the first occlusal surface 3a on the lower dental brace 2 includes a first guide surface 3aa and a second guide surface 3ab which are smoothly connected and angularly arranged, and the second guide surface 3ab protrudes backward relative to the first guide surface 3aa, so that when the second guide surface 3ab matches the first occlusal surface 3a of the upper stabilizing block 31, it further pulls the mandible forward.

[0060] At the same time, when the wearer is completely relaxed in the normal state, the first guide surface 3aa and the corresponding first occlusal surface 3a can be matched to play a stabilizing role by setting the length and angle of the upper stabilizing block 31 and the lower stabilizing block 32, and when the wearer is partially relaxed, that is, slightly occluded, the second guide surface 3ab and the corresponding first occlusal surface 3a are matched to play a stabilizing role, providing the wearer with more diversified choices and further improving the comfort of the device.

[0061] The slope of the second occlusal surface 4a on the upper dental brace 1 is greater than the slope of the second occlusal surface 4a on the lower dental brace 2 relative to the vertical direction, so that when the two are occluded, the second occlusal surface 4a on the upper dental brace 1 will pull the second occlusal surface 4a on the lower dental brace 2 forward, thereby achieving the correction process. And only after the two first occlusal surfaces 3a are occluded, the two second occlusal surfaces 4a can be matched with each other.

[0062] Embodiment 2:

[0063] Referring to Figures 1-15 , the embodiments of the present application further have the following technical solutions in addition to all the technical solutions of the above embodiments:

[0064] The stabilizing assembly 3 and the correcting assembly 4 are detachably fixedly connected with the corresponding upper dental brace 1 and lower dental brace 2.

[0065] In this embodiment, the modular, detachable structural design gives the device extremely high clinical adaptability and treatment flexibility. Doctors can easily replace or reconfigure the stabilization block and bite pad according to the specific needs of patients at different stages of rehabilitation, such as adjustment of traction strength, change of reduction target, or the need for oral hygiene maintenance. For example, in the early postoperative period, a component with a higher amount of traction is used to achieve rapid reduction, and then replaced with a maintenance component after the joint adapts to consolidate the therapeutic effect; or when cleaning the braces, functional components can be removed separately to avoid contamination of the entire device and improve patient comfort and compliance. In addition, the detachable design also facilitates the disinfection, maintenance and long-term use of the device, reducing the risk of overall scrapping due to component damage and extending its service life.

[0066] The stabilization component 3 and the correction component 4 are available in a variety of angles and sizes to create a variety of stabilization and correction levels. Each model differs in structural height, inclination angle, contact area, or guiding slope, resulting in varying degrees of stabilization and correction. For example, the stabilization component 3 offers three levels of stability: low, medium, and high, corresponding to different depths and locking strengths of the first occlusal surface 3a, suitable for different clinical needs, ranging from mild release to strong guidance. The correction component 4 offers an upper bite pad 41 with a variety of protrusions and vertical heights, achieving a secondary distraction effect ranging from mild to significant. These different models can be used in conjunction with a detachable connection structure, allowing clinicians to flexibly select and combine the most appropriate stabilization and correction levels based on the patient's preoperative imaging assessment, intraoperative joint status, postoperative recovery progress, and individual tolerance. In the early stages of rehabilitation, a combination of high stability and medium correction can be used to ensure stable disc reduction. As function gradually recovers, the patient can transition to medium stability with a progressive correction component 4 to train the coordination and proprioception of the surrounding muscles. This multi-model, modular configuration strategy not only expands the device's adaptability to meet the needs of patients with varying anatomical features and pathological severity, but also makes the treatment process more refined and step-by-step, avoiding the risks of over-traction or undercorrection. Combined with the ease of cleaning and component replacement afforded by a detachable design, the entire system significantly enhances patient comfort, treatment safety, and long-term compliance while ensuring precise mechanical transmission. This helps accelerate postoperative functional restoration, reduce recurrence rates, and achieve superior clinical rehabilitation outcomes.

[0067] Example 3:

[0068] Reference Figures 1-15 In addition to all the technical solutions of the above embodiments, the embodiments of the present invention further have the following technical solutions:

[0069] The upper dental brace 1 and the lower dental brace 2 are provided with an insertion block 5 corresponding to the upper stabilizing block 31, the lower stabilizing block 32, the upper bite pad 41 and the lower bite pad 42, and the upper stabilizing block 31, the lower stabilizing block 32, the upper bite pad 41 and the lower bite pad 42 are all provided with an insertion slot X;

[0070] The upper stabilizing block 31 and the upper bite pad 41 can cooperate the insertion slot X and the insertion block 5 from bottom to top, and the lower stabilizing block 32 and the lower bite pad 42 can cooperate the insertion slot X and the insertion block 5 from top to bottom.

[0071] In this way, the occlusion action of the wearer is conducive to establishing a connection relationship between the stabilizing assembly 3 and the correcting assembly 4 and the upper dental brace 1 and the lower dental brace 2, thereby effectively avoiding the falling of the two, and improving the use reliability of the stabilizing assembly 3 and the correcting assembly 4.

[0072] Specifically, the insertion block 5 and the insertion slot X can be respectively provided as a T-shaped block and a T-shaped slot.

[0073] More specifically, the T-shaped block and the T-shaped slot can further be provided with locking convex points and locking grooves to improve the locking reliability of the two. The two can also be locked by means of interference fit.

[0074] Embodiment 4:

[0075] With reference to Figures 1-9 In addition to the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0076] The stabilizing assembly 3 and the correcting assembly 4 are located on the inner side of the teeth, i.e. close to the tongue side or the palate side. This layout design fully considers the comfort, aesthetics and naturalness of the oral function of the patient. Placing the functional components on the inner side of the teeth avoids setting protruding structures on the labial and buccal sides, significantly reduces the friction and pressure on the labial soft tissue, reduces the common foreign body sensation and mucosal irritation in the early wearing period, and improves the patient's tolerance and compliance. At the same time, the inner side arrangement makes the overall appearance of the device more concealed, and the patient is not easily noticed in daily communication or social occasions, effectively relieving the psychological burden caused by wearing the device. In addition, this position is closer to the mechanical axis of the temporomandibular joint, which helps to transmit the traction force along a path that is more in line with the physiological direction, reduces unnecessary lateral component or rotational moment, thereby improving the accuracy and stability of the disc reduction.

[0077] Embodiment 5:

[0078] With reference to Figure 14 and Figure 15 In addition to the above-mentioned embodiments, the embodiments of the present application further have the following technical solutions:

[0079] The upper stabilizing block 31 and the lower stabilizing block 32 are respectively formed with a guide groove 3b and a guide protrusion 3c; when the upper stabilizing block 31 and the lower stabilizing block 32 are matched, the guide groove 3b and the guide protrusion 3c can cooperate with each other to achieve occlusal positioning of the mandible.

[0080] In this embodiment, when the upper and lower braces 2 are closed and the stabilizing blocks are close to each other, the guide protrusion 3c can be accurately inserted into the corresponding guide groove 3b, realizing mechanical guidance and limiting. This guide structure plays a positioning role when the patient performs the bite action, ensuring that the upper stabilizing block 31 and the lower stabilizing block 32 are always fitted with the preset path and angle, avoiding the deviation of the traction direction due to lateral slippage, rotation or dislocation. The cooperation between the guide groove 3b and the guide protrusion 3c not only speeds up the bite into place, allowing the patient to reach the target mandibular position more naturally and conveniently in daily use, but also significantly improves the consistency of each bite reduction, which is crucial for establishing a stable mandibular physiological position in the early postoperative period. Especially when the patient's muscles are still in the adaptation or spasm recovery stage, this guide mechanism can help them quickly and accurately find the correct protrusive position, reducing the adverse effects caused by subjective judgment errors.

[0081] Specifically, the guide groove 3b and the guide protrusion 3c are both provided on the corresponding first occlusal surface 3a to ensure that the two can fit together and play a guiding role when the two first occlusal surfaces 3a are matched.

[0082] Example 6:

[0083] The composite occlusal device is used as a correction device for arthroscopic disc reduction surgery, so the correction device after arthroscopic disc reduction surgery has all the beneficial effects of the occlusal device in any of the above embodiments.

[0084] After the articular disc reduction surgery is completed under arthroscopy, the inflammatory response in the joint cavity has not completely subsided, and the articular disc and surrounding ligaments and synovial tissues are in the early stages of repair. At this time, it is crucial to maintain the stable position of the mandible and avoid abnormal movement. After the patient wears the device, during the mouth closing process, the stabilization component 3 first plays a role, and through the precise fit of the occlusal surfaces of the upper stabilization block 31 on the upper brace 1 and the lower stabilization block 32 on the lower brace 2, the mandible is guided to produce a moderate forward displacement of the first distance, achieving a first-level traction. This amount of traction is set through precise preoperative evaluation and is sufficient to maintain the normal anatomical relationship between the articular disc and the condyle, and prevent re-dislocation caused by muscle spasms or habitual retraction in the early postoperative period. At the same time, because of its mild displacement, it will not cause excessive traction on the newly reduced joint tissue, effectively reducing postoperative pain and discomfort, which is conducive to patients' rapid adaptation and persistence in wearing, and ensuring the initial stability of the reduction results.

[0085] As the patient actively performs deeper bite action in the rehabilitation training, the correction assembly 4 intervenes. Since the device can realize two-stage traction during use, this process is designed to make the stable assembly 3 and the correction assembly 4 not work at the same time, that is, when the correction assembly 4 works, the upper stable block 31 and the lower stable block 32 are out of contact, ensuring that the function switching is clear and does not interfere with each other. This phased and progressive traction mechanism simulates the physiological mandibular protrusion process, allowing the posterior band of the disc to smoothly and fully cover the front edge of the condyle, significantly increasing the joint space and relieving the intra-articular pressure, providing a favorable biomechanical environment for the repair of synovial and ligament tissues. What is particularly important is that since the two-stage traction is carried out on the basis of the first-stage stability, the mandible has been pre-adapted to the partially protruded state, so that when entering a deeper correction position, the muscle stretch felt by the patient is significantly reduced, effectively avoiding muscle tension or joint area pain caused by sudden large-scale forward movement, and improving the safety and comfort of treatment.

[0086] In addition, the device integrates the functions of stability and correction, eliminating the need to replace two independent devices at different stages after surgery, avoiding treatment interruptions, bite reference loss, and additional molding, production costs, and clinical recheck times caused by the replacement process.

[0087] Embodiment 7:

[0088] Embodiments of the present application provide a production method of a composite bite device, which is suitable for producing the composite bite device in any of the above embodiments. The production method comprises:

[0089] S1: determining the actual bite dynamics of the patient;

[0090] S2: producing the composite bite device based on the actual bite dynamics.

[0091] Determining the actual bite dynamics of the patient specifically refers to determining the actual bite dynamics of the patient through CT, nuclear magnetic resonance, and multi-dimensional integration of jaw frame diagnostic information.

[0092] In this embodiment, the production method of the composite bite device aims to accurately adapt to the individual anatomical structure and postoperative rehabilitation needs of the patient, ensuring that the device produced can effectively realize the stable reduction and functional reconstruction of the temporomandibular joint disc after arthroscopic surgery. The method comprises comprehensively collecting and analyzing the actual bite dynamics of the patient, and customizing the production of the composite bite device based on the dynamic data.

[0093] In step S1, the actual occlusion dynamics of the patient is determined not relying on a single image or static model, but through the integration of multi-dimensional information from CT, magnetic resonance imaging (MRI), and mechanical jaw frames. CT provides accurate three-dimensional morphology of the bony structure, including the maxilla, mandible, and the bony relationship of the temporomandibular joint; MRI clearly presents the position and shape of the disc and its relative relationship with the condyle, especially the dynamic changes in the open and closed positions, which can determine whether there is disc displacement, deformation, or adhesion; by importing the above image data into a digital analysis system and combining facebow transfer technology to accurately transfer the movement trajectory of the patient's mandible relative to the skull base to an adjustable jaw frame, a virtual or physical model that can simulate the actual mandibular movement path is constructed. On this basis, the patient's preoperative ideal reduction state, including the range of mandibular protrusion, lateral movement, and vertical opening, is further recorded, and a "actual occlusion dynamics" database is formed, which includes spatial position, movement trajectory, and occlusal contact characteristics. This process not only reflects the static anatomy, but also captures key parameters in functional movement, providing physiological basis for subsequent device design.

[0094] In step S2, based on the actual occlusion dynamic data obtained, a composite occlusion device is produced using digital design and manufacturing technology. First, the inner fitting shape of the upper and lower dental braces 1 and 2 is constructed using software to ensure a high fit with the patient's dental arch contour on the lingual / palatal side, taking into account retention and comfort. Then, according to the preset primary traction distance, the relative positions of the upper and lower stabilizing blocks 31 and 32 are simulated on the virtual jaw frame, and the matching structure of the occlusal surface angle, guide groove 3b, and guide protrusion 3c is designed to ensure stable fitting and precise guidance at the target protrusion position. At the same time, it enables smooth sliding of the mandible to the final functional position during the secondary traction stage. All components are parameterized modeled according to multi-model standards to facilitate selection of appropriate grades according to clinical needs. Finally, the dental brace body can be integrally formed using high-precision 3D printing or numerical control cutting technology with biocompatible medical materials, and the detachable stabilizing blocks, occlusal pads, and other modules can be processed into independent components through standardized interface structures to realize modular assembly of the device. This production method not only ensures the high consistency of the device with the individual occlusion dynamics of the patient, but also supports the replacement of different types of functional components during postoperative follow-up according to the recovery situation, enabling dynamic adjustment and long-term use, significantly improving the precision, repeatability, and clinical adaptability of the treatment.
