Description

Technical Field

[0001] The utility model relates to the field of an appliance which is mounted on an alveolar bone to mount a denture on a jaw bone, in particular to an implant fixing bracket. Background Art

[0002] After tooth loss, alveolar bone often undergoes secondary resorption and atrophy, resulting in insufficient bone mass to support the stable placement of implants. This phenomenon is particularly common in the elderly and patients with long-term edentulousness.

[0003] With the rapid development of dentistry and biomaterials, bone augmentation has become an important means of addressing alveolar bone defects and improving the success rate of dental implants. Titanium abutment brackets, key components in bone augmentation procedures, have become a hot topic in research and application due to their excellent biocompatibility, mechanical strength, and corrosion resistance. Therefore, restoring sufficient bone volume through bone augmentation has become a pressing issue in the field of dentistry.

[0004] Titanium alloys are widely used in medical devices due to their excellent biocompatibility, high strength, and corrosion resistance. In dental implants, titanium has become the material of choice for components such as implants, abutments, and stents. Titanium abutment stents for bone augmentation, a crucial component of bone augmentation procedures, not only provide stable support but also promote the growth and differentiation of bone cells, accelerating bone healing.

[0005] In the early days, bone augmentation surgery and implant placement surgery were performed in batches. For patients, both surgeries would increase the number of pain episodes and prolong their discomfort. In addition, the recovery period of the surgical incision would also affect the patient's daily activities. Therefore, traditional dental implant technology is not mature and needs improvement and innovation. In order to promote the development of bone augmentation technology and improve surgical results, we continue to explore the design of new bone augmentation titanium abutment brackets. Utility Model Content

[0006] In order to solve the above problems, the utility model provides an implant fixing bracket, which is provided with a base for implantation, eliminating the need for implantation surgery again, thus saving operation time.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an implant fixing bracket, including a support structure adapted to the shape of the alveolar bone, a fixing part is provided on the support structure, and the support structure is fixed to the periphery of the alveolar bone through the fixing part, so that the support structure is tightly fitted with the surface of the alveolar bone to be repaired, and is characterized in that the support structure has contact surfaces corresponding to the inner and outer sides of the alveolar bone, and the contact surfaces are connected by a connecting surface that jumps over the alveolar bone, and a base connected to the crown is provided on the connecting surface, and there are multiple connecting surfaces, and the intervals between the connecting surfaces form a first opening portion for filling bone material, and a second opening portion is provided on the contact surface, so that the bone material supports the healed gums in the second opening portion.

[0008] Furthermore, the supporting structure is a surrounding bracket, and the surrounding bracket is formed by integrally molding a contact surface and a connecting surface.

[0009] Furthermore, the fixing portion is located on the edge of the contact surface, and the fixing portion is a positioning portion with a threaded hole.

[0010] Furthermore, the positioning portion is an arc-shaped positioning protrusion, and the protruding direction of the positioning protrusion points to the gums.

[0011] Furthermore, the contact surface has a curved surface portion connected to the connection surface.

[0012] Furthermore, the surrounding bracket is made of plastic titanium material.

[0013] Furthermore, the first opening and the second opening are both polygonal in shape, and have rounded corners between the edges.

[0014] Furthermore, an internal thread is provided on the base.

[0015] Beneficial effects of the utility model:

[0016] The utility model mainly provides an abutment connected to the crown on the supporting structure. Specifically, the abutment is located on the connecting surface of the two contact surfaces, which means that the supporting structure itself has already undergone part of the implant denture process. That is to say, the implant object of the implant is the supporting structure. For the patient, this simplification effectively reduces the contact surface between the implant and the jawbone, reduces the amount of bone in contact and reduces the difficulties that may be caused by bone loss. Therefore, it avoids another implant surgery at a later time and saves operation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] This embodiment is a planting fixing bracket, such as Figure 1-6 shown.

[0024] The bracket is directly applied in the oral cavity through implant surgery, and the bracket has a base 1 connected to the crown. This combination can reduce the harm caused to the patient again for the technical development of implant dentures. The traditional implantation method is to hollow out part of the new bone and then implant the implant, while the implant in the present invention is directly pre-installed on the bracket. Therefore, this reduction in the number of operations can shorten the surgical incision and reduce pain and difficulty of the operation.

[0025] This bracket includes the following structures:

[0026] An enclosing bracket is formed by connecting two contact surfaces 3 by a connecting surface 2. The contact surfaces 3 are distributed on the inner and outer sides of the alveolar bone. A fixing part is provided on the contact surface 3, and the fixing part is fixed to the mid-face pillar, piriform and zygomatic pillar by screws. There are multiple ones on the connecting surface 2, and they exist in the form of interval distribution. The intervals between the connecting surfaces 2 form a first opening 21 for filling bone material. The filling amount is consistent with the curvature of the alveolar bone and the connecting surface 2. The base 1 is set on the connecting surface 2.

[0027] In summary, after using the present invention to implant an implant, the patient can reduce the number of surgeries and the number of postoperative recovery times, allowing the patient to adapt to daily activities more quickly.

[0028] With the development of digital technology, 3D printing, computer-aided design (CAD), and computer-aided manufacturing (CAM) have gained widespread application in the medical field. These technologies enable personalized design and precise manufacturing of implant scaffolds. By extracting the patient's CBCT images and performing 3D reconstruction, a titanium implant abutment scaffold can be designed to perfectly match the defect area. This abutment can then be printed using 3D printing technology and titanium materials, saving surgical time while improving precision and effectiveness.

[0029] The above-mentioned fixed part is one of the areas on the contact surface 3. In the present embodiment, the fixed part is a vestibular wing 33 with a screw hole. There are four vestibular wings 33. The vestibular wings 33 are located on the edge of the contact surface 3. With this design, the vestibular wings 33 can be closer to the mid-face pillars, piriform and zygomatic pillars (the bone thickness here is most likely to ensure stability), and the stability of the surrounding bracket is better.

[0030] Furthermore, the vestibular wing 33 is an arc-shaped positioning protrusion, and the protruding direction of the positioning protrusion points to the gums. This arc-shaped design mainly highlights the smooth effect of the positioning part to avoid damage to soft tissue.

[0031] Similarly, the contact surface 3 has a curved portion 32 connected to the connecting surface 2. This design also avoids the appearance of sharp corners, and the smooth surface improves the safety of installing the surrounding bracket in the oral cavity.

[0032] The connecting surface 2 is also in an arched arc shape.

[0033] A second opening 31 is provided on the contact surface 3. The second opening 31 has two effects. First, it is to enhance the plasticity of the surrounding bracket. The surrounding bracket is 3D printed using titanium material. A smaller usable area means that it is easier to bend and deform when subjected to force; second, the new bone heals with the gums through the second opening 31, making the surrounding bracket more stable on the alveolar bone.

[0034] The area between the second openings 31 on the contact surface 3 is a fixed connection point, so that the design of the bracket ensures precise matching with the alveolar bone surface and has good marginal closure to reduce the risk of soft tissue collapse and non-osteoblast growth.

[0035] The first opening 21 and the second opening 31 are both polygonal in shape, and have rounded corners between the edges. Of course, the purpose of providing the rounded corners is to avoid damage to soft tissues.

[0036] The base 1 is an implant used in conjunction with the dental crown, and an internal thread is provided on the base 1.

[0037] In this regard, the present invention, which is prepared using 3D printing technology, provides great flexibility in implant design by producing implant structures through additive manufacturing technology. Many shapes and geometries are easier to achieve than using traditional or alternative production methods. Combined with finite element analysis, it is possible to identify and strengthen the key points of the implant structure while reducing the number of fastening points and optimizing their positions. In addition, the simplification of manufacturing constraints helps to reduce the contact surface between the implant and the maxillary bone by 3, reducing the amount of bone in contact and reducing the difficulties that may be caused by bone loss. Ultimately, this treatment method can shorten the surgical incision, reduce pain and surgical difficulty, facilitate the fixation of implant screws through osteosynthesis, and reduce postoperative recovery, allowing patients to adapt to daily activities more quickly.

[0038] The steps for preparing the titanium abutment framework for implantation are as follows:

[0039] Step 1: Perform a CT scan of the oral cavity to obtain tooth and jaw data, and import the acquired data into the software to reconstruct a three-dimensional model of the alveolar bone;

[0040] Step 2: Based on the reconstructed 3D alveolar bone model, the defect location is determined. The size and structure of the design must match the patient's needs. Adjustments are made based on the defect size, biomechanical properties, and digital design. A 3D structural model of the implant titanium abutment bracket that perfectly matches the defect area is simulated and designed in the software.

[0041] Step 3: Import the three-dimensional structural model of the implant titanium abutment bracket into the 3D printing device, tilt it 30° to 60°, determine the support structure based on the placement of the implant titanium abutment bracket, and use laser powder bed melting technology to print layer by layer on the powder bed to generate a personalized implant titanium abutment bracket;

[0042] Step 4: After the implant titanium abutment bracket cools to room temperature, it is taken out of the equipment, the support is removed, and the implant titanium abutment bracket is surface treated to remove unmelted particles adhering to the surface;

[0043] Step 5: Surface treatment of the titanium abutment bracket also includes sandblasting and polishing. Sandblasting uses compressed air as a power source to form a high-speed jet beam that sprays 120-mesh aluminum oxide sand onto the surface of the titanium abutment bracket at high speed, giving the surface a uniform off-white color. After sandblasting, the surface achieves a certain degree of cleanliness and varying degrees of roughness, improving the surface's mechanical properties and fatigue resistance. After polishing, the bracket is ultrasonically cleaned in an anhydrous ethanol solution for 5 to 30 minutes. This results in the titanium abutment bracket.

[0044] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
