Description

TECHNICAL FIELD

[0001] The utility model belongs to the medical auxiliary equipment technical field, especially relates to a personalized interstice retainer after ameloblastoma operation. BACKGROUND

[0002] Ameloblastoma (AM) is a relatively common benign tumor of the head and neck, with an incidence of about 0.5 / 100,000, accounting for 1% of oral tumors. AM has the characteristics of local invasive growth, easy recurrence and other malignant tumors, often accompanied by loose teeth, persistent nerve numbness, jaw necrosis and other clinical symptoms, which greatly affects the quality of life of patients. At present, the treatment of ameloblastoma mainly includes local window curettage and radical osteotomy surgery with vascularized fibula repair. For patients who cannot be operated, radiotherapy, chemical drugs, targeted therapy and other treatments can improve the prognosis under the preservation of organs, but they are rarely used.

[0003] Radical osteotomy surgery is suitable for patients with solid type, recurrent type, multicystic type and malignant tendency of ameloblastoma.

[0004] Although the thoroughness is guaranteed, the operation incision is large, and local lesions and mandibular resection are required, which results in the loss of occlusion function after operation, and the fibula, which plays an important auxiliary supporting role in the lower limbs, needs to be sacrificed. Postoperative infection and vascular anastomosis failure lead to bone graft failure, which is devastating.

[0005] Window curettage is suitable for wall single-cystic ameloblastoma and single-cystic or multicystic ameloblastoma in young children, which accounts for the majority of ameloblastoma. Window curettage to some extent retains the patient's appearance and occlusion relationship, avoids the sacrifice of fibula and vascularized fibula transplantation and other high-difficulty surgeries. After the lesion is thoroughly cured and active dressing is performed, the new growth of the original cystic cavity of the mandibular bone can almost restore the mandibular bone to its original state, showing its superiority in treatment. However, the ameloblastoma of the mandibular bone has a relatively large cavity, and the healing time is relatively long. After operation, iodine formocresol gauze needs to be repeatedly replaced for dressing until the cystic cavity is reduced to disappear. This process takes more than half a year or even a year, and the odor of iodine formocresol gauze and the pain caused by the replacement of iodine formocresol gauze every time bring great pain to patients. Whether a substitute for iodine formocresol gauze dressing can be found to achieve its effect while reducing the occurrence of complications is of great significance to improve the quality of life of patients. UTILITY MODEL CONTENTS

[0006] In view of the above problems in the prior art, the utility model aims to provide a personalized interstitial retainer after ameloblastoma operation, which solves the problems of traditional use of iodine formocresol gauze to support windowing, such as replacement trouble, increased patient pain and poor patient experience.

[0007] In order to achieve the above-mentioned utility model purposes, the technical scheme adopted by the utility model is as follows:

[0008] Provided is an individualized interstice retainer after ameloblastoma surgery, which comprises a first base, which is used to cover alveolar bone, a window top and mucosa on both sides of the window; a bottomless support chamber is arranged below the first base and inside the window; a needle hole is arranged on the top of the first base and communicates with the bottomless support chamber; and an overflow hole is arranged on each side of the first base.

[0009] The basic principle of the individualized interstice retainer after ameloblastoma surgery in the utility model is that the bottomless support chamber is arranged on the first base and inside the window, so that the window after ameloblastoma surgery is supported, epithelial proliferation on the window top is avoided, a large cavity is formed, and infection is caused. When the window is flushed, a syringe can be used to flush the inside of the window through the needle hole, and the overflow hole is used to drain pus or other secretions from the window, so that the window is finally flushed, the traditional method of supporting the window with iodoform yarn is replaced, and the problems of replacement inconvenience, increased patient pain and poor patient experience are avoided.

[0010] Further, as a specific arrangement of the first base, the first base comprises a top covering portion, and side covering portions are arranged on both sides of the top covering portion; the top covering portion is used to cover alveolar bone and the window top, and the two side covering portions are used to cover mucosa on both sides of the window, respectively.

[0011] The needle hole is arranged through the top covering portion, and the two overflow holes are arranged through the two side covering portions, respectively.

[0012] When the first base is specifically manufactured, the mouth of the patient can be imprinted, and then the entire first base and the bottomless support chamber are customized according to the shape of the impression, so that the first base and the bottomless support chamber are adapted to each patient.

[0013] Further, the individualized interstice retainer after ameloblastoma surgery further comprises a denture portion, which comprises a denture fixedly connected to the front side of the top covering portion through a metal ring, and the denture is implanted on the alveolar bone. The purpose of designing the denture portion is twofold. First, the first base and the denture are fixedly connected through the metal ring, so that the position of the first base is fixed. Second, the problem of tooth loss at the window is solved. The arrangement of the denture can restore the occlusal force of the patient to a certain extent, and the influence on the quality of life of the patient is minimized.

[0014] Further, the denture part further comprises a second base, the front side and the back side of the second base are respectively used for fixed connection with the denture and the tooth reserved in surgery.

[0015] Further, the first base, the second base and the bottomless support chamber are all manufactured by 3D printing technology, and the materials of the first base, the second base and the bottomless support chamber are all resin, so that the personalized customization can be carried out according to the specific conditions of different patients, and the use requirements of different patients can be met.

[0016] Further, the diameter of the pinhole is 2cm, and the diameter of the two overflow holes is 1cm.

[0017] Further, the height of the top of the top covering part is lower than the height of the top of the denture, and the spacing between the height of the top of the top covering part and the height of the top of the denture is 3mm-4mm. The above arrangement makes the denture part bear part of the occlusal force, but the first base does not bear the occlusal force, so as to avoid jaw trauma.

[0018] The beneficial effects of the utility model are as follows:

[0019] 1. The personalized interstitial maintainer after ameloblastoma surgery, the bottomless support chamber is used for supporting the postoperative window, avoiding epithelial proliferation of the top of the window, forming a large range of cavities and causing infection; meanwhile, the syringe barrel is convenient to flush, replacing the traditional method of supporting the window by using iodoform gauze, so that the problems of replacement trouble, increased patient pain and poor patient experience are avoided.

[0020] 2. The personalized interstitial maintainer after ameloblastoma surgery, the denture part is additionally arranged, so that the occlusal force of the patient can be recovered to a certain extent, and the influence on the life quality of the patient is minimized.

[0021] 3. The personalized interstitial maintainer after ameloblastoma surgery, the structure is simple, and the use requirements of different patients can be met through personalized customization. DRAWINGS
