Description
Technical Field
The invention belongs to the technical field of dental restoration devices, and particularly relates to a personalized immediate restoration device after immediate planting.
Background
With the popularization of the implant concept with restoration as a guide, the standard of implant success is not only limited to obtaining good osseointegration and long-term stability, but also puts higher demands on post-implant aesthetic restoration. Especially in the anterior maxillary dental region, the time of missing teeth of patients is reduced as much as possible during the implantation and repair, and better aesthetic effect is obtained.
In conventional implant restorations, the patient needs to wait for the implant to complete osseointegration after implantation of the implant before final restoration can be performed, so the patient has a toothless period of at least 4-6 months. This time can cause significant inconvenience to the patient's daily life, work, and social interaction. Meanwhile, the gum shape can be changed after the teeth are missing, after the suffering teeth are removed, the gum nipple can collapse and shrink due to the lack of hard tissue support, and the gum height can be reduced to different degrees, so that the difficulty of aesthetic repair can be increased, and the aesthetic effect after repair is affected. Immediate restoration by implantation immediately after tooth extraction, i.e. immediate implantation of an implant and immediate installation of a temporary restoration after tooth extraction, has the advantages of reducing the number of times of patient's visits, reducing wounds, shortening the period of no tooth deficiency, retaining the amount of soft and hard tissues to the greatest extent, and the like, and therefore, is receiving more and more attention.
In clinical practice, the implant can be repaired immediately only if the initial stability of the implant is more than 35N cm, otherwise, the implant is in failure risk. In most cases, particularly in the anterior maxillary dental region, the alveolar fossa is deep and wide in diameter after tooth extraction, and the gap between the alveolar bone and the implant is large, so that the alveolar bone cannot provide sufficient initial stability for the implant, and the implant cannot be repaired immediately after tooth extraction is performed on a patient. At this time, the doctor can only make extra operation incision on the adjacent gum soft tissue, and transfer the surrounding soft tissue valve to close the open wound after tooth extraction and implantation. At the same time, the restoration of the dental crown can be delayed until 4-6 months later.
For the front tooth area, which is an aesthetic relevant area noticed by people in the social process, the initial stability of the implant after implantation is poor due to large implantation gaps and the like, so that the patient cannot repair the implant immediately after tooth extraction. Therefore, the patient still has a toothless period of 3 months to half a year after the implant implantation is completed, and the social contact of the patient is hindered. In the clinic, a patient is planted to obtain a temporary prosthesis, the temporary prosthesis is often required to be repaired by adopting a removable denture (movable denture), but the removable denture cannot provide support for the papilla of the gingiva, so that the natural shape of the gingiva at the tooth-missing site cannot be maintained, the shaping of the shape of the gingiva at the aesthetic area of the later stage of the patient is difficult, and the movable denture is required to be taken down and cleaned by the patient after each meal, so that the temporary prosthesis is inconvenient to use.

Advantageous effects
The invention discloses a personalized immediate restoration device after immediate implantation, which comprises an absorbable film material, a temporary dental crown and a bridge-like connecting device connected with adjacent teeth on two sides. The absorbable membranous material is contacted with the bottom of the temporary dental crown, and can isolate the temporary dental crown from the implant implanted in the bone, thereby avoiding micro-motion caused by the fact that the implant is required to provide temporary dental crown retention when the temporary dental crown is used for immediate restoration at present, and avoiding force interference of the implant and bone combination in the occlusion process, and even bone combination failure. The temporary dental crown can be adjusted and ground by the natural dental crown pulled out by a patient, the temporary dental crown is fixed by the bridge-like connecting device through the double-side adjacent teeth, and the forces in the occlusion process are dispersed by the bridge-like connecting device by utilizing the periodontal potential of the adjacent teeth, so that the temporary dental crown has higher firmness as a substitute of the removable denture in the prior art, and the temporary dental crown can be used by the patient to normally occlude or even attempt to bite harder foods. The bridge-like connection device uses a fiber splint and a photo-curing flowable resin to connect the temporary crown and the adjacent teeth on both sides after the photo-curing lamp irradiates light. The device can instantly recover the dentition defect after tooth extraction, so that a patient can instantly repair even if the initial stability of the implant is insufficient, the whole tooth extraction-implantation-repair process has no tooth deficiency period, and the appearance of the patient is ensured to be attractive.
Meanwhile, the device can effectively seal the planting wound immediately after tooth extraction and maintain the natural outline form of the gum soft tissue, thereby laying a good foundation for the aesthetic effect of final restoration of later planting.
