Abstract
Description
Technical Field
[0001] This utility model relates to a periodontal drug delivery time extension guide plate, belonging to the field of oral auxiliary medical technology. Background Technology
[0002] In oral diseases, some occur between the teeth and gums, affecting both. Treatment typically involves topical periodontal medications. Some medication carriers require the patient to close their lips to hold them in place after treatment, or rely on simple oral movements to compress them. However, this method of administration often results in the medication leaking out with saliva and during oral movements, reducing its effectiveness.
[0003] Existing drug delivery methods cannot simultaneously meet the requirements of precise drug targeting and long-term drug retention: on the one hand, drugs or patches are easily diluted or washed away by saliva or bleeding gums, leading to a decrease in drug concentration and making it difficult to maintain an effective concentration, which restricts the clinical efficacy of long-term drug delivery.
[0004] Therefore, a periodontal medication time extension guide is needed to prevent drug leakage, increase the time the drug stays at the affected area, and ensure the therapeutic effect of the drug. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a periodontal drug time extension guide plate, which solves the problems of easy drug leakage and insufficient drug residence time at the affected area.
[0006] The technical problem to be solved by this utility model is achieved by the following technical solution: 1. A periodontal medication time extension guide plate, comprising...
[0007] Guide plate,
[0008] The guide plate can be positioned at the patient's periodontal location.
[0009] The guide plate has an occlusal opening at its top, through which the top of the patient's teeth can protrude.
[0010] The bottom of the guide plate covers the patient's gums, and the guide plate has a periodontal drug coverage area at the position between the patient's gums and teeth, which can accommodate the drug.
[0011] Preferably, the guide plate is made around the patient's upper or lower teeth.
[0012] Preferably, the periodontal medication coverage area is placed on the affected area of the patient, and the periodontal medication coverage area is a hollow groove that does not come into contact with the patient.
[0013] Preferably, the bottom of the guide plate is fitted to the patient's gums, and the top is fitted to the patient's dental crown.
[0014] Preferably, the guide plate is integrally formed by 3D printing.
[0015] Preferably, the model of the guide plate is derived from the scanning model of the patient's teeth by the oral scanner.
[0016] The beneficial effects of this utility model are:
[0017] This invention utilizes a guide plate that wraps around and positions the patient's maxilla or mandible, preventing displacement or loosening during wear and ensuring precise positioning. Through digital design and integrated 3D printing manufacturing, the guide plate achieves a high-precision fit to the patient's tooth-gingival anatomical contours, significantly improving sealing, preventing saliva from eroding the drug reservoir, and extending drug retention time. An occlusal opening allows the patient to maintain normal biting and chewing functions while wearing the guide plate, without affecting speech or breathing, improving comfort and compliance. A periodontal drug coverage area ensures stable containment and microenvironmental sealing of antibacterial gels, microspheres, or sustained-release tablets, allowing for continuous drug release and deep penetration into the periodontal pocket within a predetermined timeframe.

[0022] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Example 1
[0024] like Figures 1-3 As shown, a periodontal medication time extension guide includes a guide plate 1, on which an occlusal opening window 2 and a periodontal medication coverage area 3 are provided.
[0025] In this embodiment, the guide plate 1 is U-shaped and is integrally formed according to the patient's maxillary or mandibular dentition and gingival contour. It mainly includes the guide plate 1, the occlusal opening window 2, and the periodontal drug coverage area 3.
[0026] The guide plate 1 is equidistantly encircled along the dental arch, extending from the edge of the guide plate 1 to the mesial and distal ends of the molars to ensure stable positioning. The bottom of the guide plate 1 fits against the patient's gingiva, and the top of the guide plate 1 fits against the patient's crown, forming a relatively closed environment.
[0027] An occlusal opening 2 is provided at the top of the guide plate 1. The shape of the occlusal opening 2 corresponds to the shape of the patient's teeth. Each tooth that needs to participate in occlusion corresponds to one occlusal opening 2, and the center of the occlusal opening 2 corresponds to the center of the tooth crown. The edges of the occlusal opening 2 are rounded to avoid damage to the patient's oral soft tissues.
[0028] After wearing the tooth, the patient can bite, chew, and eat normally. The occlusal opening 2 ensures that the patient's daily functions are not affected. The occlusal opening 2 can also be closely aligned with the crown, further facilitating the installation of the guide plate 1.
[0029] A periodontal medication coverage area 3 is provided on the guide plate 1. The periodontal medication coverage area 3 is a hollow groove, specifically a ring-shaped or strip-shaped groove set along the dentition. The cross-section of the periodontal medication coverage area 3 is semi-circular or isosceles trapezoidal. It is located on the inner side of the guide plate 1, at the junction between the patient's tooth and gingiva, with a certain gap between it and the patient's tissues. The periodontal medication coverage area 3 is integrally formed with the guide plate 1, without any sharp angles, reducing the risk of scratching the patient.
[0030] The periodontal medication coverage area 3 can accommodate medications, such as antibacterial gels, microspheres, or sustained-release tablets.
[0031] The periodontal drug coverage area 3 enables continuous drug release: relying on the closed or semi-closed space formed by the guide plate 1 and the tooth-gingiva, it blocks saliva rinsing and prolongs the drug retention time. The periodontal drug coverage area 3 maintains a certain gap with the gingiva, which allows the drug to penetrate below the gingiva without causing excessive pressure on the soft tissue.
[0032] In this embodiment, the guide plate 1, the occlusal opening window 2, and the periodontal drug coverage area 3 are formed in one step by the same digital model in 3D printing, which can avoid assembly gaps.
[0033] During the manufacturing process of the guide plate 1, intraoral scanning is first used to obtain digital data of the patient's dentition and gingiva, and then 3D printing is used to form a single piece to ensure that the inner and outer surfaces of the guide plate are precisely fitted with the patient's overall features.
[0034] During use, the specific working principle of the guide plate 1 is as follows: after periodontal treatment is completed and periodontal medication is placed, the patient puts on the guide plate 1, exposes the teeth in the occlusal opening window 2, and ensures that the teeth can bite normally; the medication is fixed in the periodontal medication coverage area 3.
[0035] At this time, the top of the guide plate 1 presses against the patient's crown and the bottom presses against the patient's gums, forming a nearly closed space, allowing the medication to be slowly released and deeply penetrated within the predetermined time. After wearing, it is removed, cleaned and disinfected, and can be reused after replenishing the medication as needed.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
