Problems solved by technology

There are several problems: one is that the model cannot accurately reflect the situation in the mouth
Because the mouth opening degree of the patient is reduced after the operation, and the opening position is not limited to the alveolar ridge, the plaster model taken may not accurately reflect the actual situation in the mouth, which ultimately affects the smooth placement of the plug
The second is the fracture residue of the impression material
Because the cavity opening is often smaller than the inner diameter of the cavity, the material is easy to break and leave the cavity when the impression is made, which increases the risk of postoperative infection
Thirdly, the production cycle of the plugging device based on the plaster model is long, which increases the risk of cyst infection and window reduction
Fourth, for large cysts with multiple directions, there is a possibility of leaving distal cysts due to premature healing of the window and premature bone formation near the opening after fenestration, resulting in failure of fenestration treatment
However, there are many aspects that need to be improved, including the early healing of the large jaw cyst near the window after fenestration, leaving a distal cyst cavity, which leads to the failure of fenestration treatment, and the inconvenience of self-rinsing for patients with deep fenestrations, etc.

Embodiment 1

[0039] Such as figure 1 As shown, this embodiment provides a 3D printing step-back jaw cyst stopper, which is formed together by 3D printing, including a functional part 3, a retaining part 1 and a joint connected to the The piercing part 2 between the functional part 3 and the retaining part 1, wherein the functional part 3 is designed according to the shape of the capsule cavity of the patient's CT data, it is made of elastic material, and its volume is smaller than the patient's capsule cavity, used for Protrude into the patient's cavity; the retaining part 1 is designed according to the tooth and gingival tissue around the opening to play a retaining role, and it is designed to be connected to the dental crown in an embracing and / or mucosa-supporting manner based on the oral scan data. Dental and gingival tissues.

[0040] When in use, the functional part 3 is penetrated into the patient's cystic cavity, and the retaining part 1 and the tooth body and dental tissue around...

Embodiment 2

[0047] This example is an extension of Example 1. For cysts involving two anatomical regions (such as the mandibular body and the ramus of the mandible), the distal cyst is left in order to avoid premature bone formation near the opening of the cyst cavity. The functional part 3 needs to protrude into the cystic cavity in different directions according to the shape of the cystic cavity. At this time, the plugging device is divided into two parts, and the functional part 3 is designed to be in place separately, such as figure 2 shown. And it gradually adjusts its length as the patient's cyst cavity shrinks.

[0048] As for the blocking type stopper, there are two sets from the retaining part 1 to the functional part 3, and their directions are opposite.

[0049] For the flushing type plug, there are two sets from the retaining part 1 to the functional part 3, and their directions are opposite, and their ends are all provided with openings, the diameter of which is 4-6mm, and ...

Embodiment 3

[0051] This embodiment is another extension of Embodiment 1. When the depth of the patient's cyst cavity is large, in order to avoid premature bone formation of the cyst cavity near the opening of the larger cyst cavity and leave the distal cyst cavity, this embodiment Example is also provided with an extension function part 30, such as image 3 shown.

[0052] For the occlusion-type stopper, the functional part 3 includes an extension functional part 30, which protrudes from the end of the functional part 3 and extends to the distal end of the patient's cystic cavity, and gradually adjusts its length as the patient's cystic cavity shrinks, In order to prevent premature bone formation near the opening of the cyst cavity and leave the distal cyst cavity, the extended functional part 30 can be detachably connected or integrally connected with the functional part 3 .

[0053] For the flushing plug device, the functional part 3 includes an extended functional part 30, which protr...

Abstract

The invention relates to the field of auxiliary medical instruments, and particularly relates to a 3D printing step-back type jaw cyst plugging treatment device and a preparation method thereof. The 3D printing step-back type jaw cyst plugging treatment device is integrally formed and comprises a functional part, a retention part and a penetrating part connected between the functional part and the retention part, wherein the functional part is designed according to the CT data cyst cavity form of a patient, is made of an elastic material, is smaller than the cyst cavity of the patient in size and is used for protruding into the cyst cavity of the patient; and the retention part is designed according to the tooth body and gingival tissue conditions around an opening to achieve a retention effect, and a dental crown clamping and holding type and/or a mucous membrane supporting type are/is designed according to oral cavity scanning data. The 3D printing step-back type jaw cyst plugging treatment device is designed according to the CT data cyst cavity form of the patient and is smaller than the cyst cavity, meanwhile, the in-place convenience is considered, the plugging treatment device is manufactured in a 3D printing step-back mode, a doctor can design the shape and size of the plugging treatment device according to the cyst form of the patient, the manufactured plugging treatment device is more adaptive, and the manufacturing process is simpler and more convenient.

Description

technical field [0001] The invention relates to the field of auxiliary medical devices, in particular to a 3D printed step-back jaw cyst stopper and a preparation method thereof. Background technique [0002] Jaw cystic lesion is one of the common benign lesions in the oral and maxillofacial region. For large cystic lesions of the jaw, fenestration decompression is the first choice for clinical treatment. The reason is that it has less trauma and is easy to operate. Fenestration and decompression can often effectively reduce the cyst cavity, and even if a second cyst curettage is required, the damage to adjacent anatomical structures will be greatly reduced. The plug is the key device to ensure the decompression effect of window opening. Traditional plugging devices such as removable partial denture mucosa tooth support plugging device, ring lip bow type plugging device and silicone rubber drainage plugging device and so on. These stoppers need to be made on plaster mode...
