Description
Technical Field
The invention relates to the technical field of dental implantation aesthetic restoration, in particular to a personalized abutment-crown integrated temporary restoration and a preparation method and application thereof.
Background
Current dental implant restoration treatments for patients with aesthetic defects of dentition typically include three main steps: (1) implanting an implant in a first operation; (2) performing a second-stage operation after the implant is implanted for 3-6 months, exposing an implant sealing screw, replacing the implant sealing screw with a finished healing abutment or a manually-made implant support temporary crown, and performing implant peripheral soft tissue shaping; (3) and 3-4 months after the soft tissue is shaped, taking a mold to manufacture a permanent abutment and a crown restoration body, and fixing the permanent abutment and the crown restoration body on the upper implant to finish the dental implantation restoration treatment. The second stage of operation and the subsequent soft tissue shaping are one important intervention for the aesthetic effect of the implanted denture and are necessary steps for obtaining healthy and beautiful implant gum penetrating cuffs.
At present, the peri-implant soft tissue shaping generally adopts the following two methods: firstly, a finished product healing abutment is adopted for soft tissue shaping, but the implant formed after shaping has a single gum penetrating cuff shape, has larger difference between the shape and the size and the natural gum penetrating outline, is difficult to match the individual gum shape of a patient, cannot realize the optimal soft tissue aesthetic effect, and cannot wear a proper crown prosthesis in the tooth lacking area of the patient during shaping, thereby influencing the beauty and pronunciation; when a finished product healing base platform with the diameter of the gum penetrating part smaller than the diameter of the neck of the corresponding part of the natural tooth is selected, because the finished product healing base platform cannot well support soft tissues around the implant, the edge of the shaped soft tissues is positioned in the crown of the natural tooth gum, the axial length of the crown is insufficient after final restoration is finished, and the curve of the front dentition gum is not attractive. When the diameter of the gingiva penetrating part of the finished healing abutment is larger than the diameter of the neck of the natural tooth, soft tissues are excessively retracted after shaping, and the edge of the soft tissues is positioned at the root of the natural tooth and the gum, so that the axial length of the tooth crown is lengthened after final repair is finished, the gum curve is not coordinated, and the appearance is influenced. The shape of the finished healing abutment is greatly different from the shape of the neck of the natural tooth, and the finished healing abutment has single shape and lacks diversity: if the shape of the upper anterior tooth healing abutment of the finished product is cylindrical or truncated cone-shaped, the cross section is circular, the shape of the cross section is greatly different from that of the irregular circular triangle at the neck of the natural upper anterior tooth, and the ideal shaping effect of the peripheral soft tissue of the implant is difficult to achieve. And the finished healing abutment is mostly made of titanium and titanium alloy, the appearance is difficult to change, and the gingival penetrating form consistent with the natural tooth is difficult to obtain. The temporary crown is formed by manually stacking and molding resin on the temporary abutment, compared with a finished product healing abutment, the method can achieve a more ideal gum shaping effect, but a patient needs to see a doctor many times during shaping, the temporary crown is repeatedly detached from a patient implant many times, the gum penetrating outline of the temporary crown is adjusted and changed beside a chair, the number of times of patient seeing a doctor is increased, the repeated detachment of the temporary crown is easy to affect the healing of soft tissues at the gum penetrating cuff and cause pain and discomfort of the patient, and the monomer released by adding the resin when the temporary crown is adjusted and changed beside the chair and the surface of the temporary crown after adjustment and change are difficult to highly polish, so that local soft tissues can be stimulated, and the health of the patient can be affected. (Wittneben JG, Buser D, Belser UC, Bragg U.S. Peri-Implantation soft tissue conditioning with a compressive recovery in the destructive zone: the dynamic compression technique. int J Periodonics retrieval 2013,33(4)) furthermore, the shaping effect of the temporary crown made by manual stacking is completely dependent on the experience of the technician or clinician, the quality being difficult to control.
In recent years, digitization techniques have been used in implant denture repair treatments. The digital impression of dentition and oral cavity soft tissue of a patient and the three-dimensional position of an implant are obtained through an optical scanning technology, the three-dimensional image data of hard tissues such as teeth, jaw bones and the like of the patient are obtained through a Cone Beam CT (CBCT) technology, and an implant abutment and an upper part repairing structure (a crown, a bridge and the like) are designed and manufactured through a CAD/CAM technology by combining the data of the dentition and the oral cavity soft tissue of the patient and the three-dimensional image data of the hard tissues such as the teeth, the jaw bones and the like. The development of these digital techniques provides the possibility to make an implant support temporary restoration with a personalized, transgingival contour more closely resembling the transgingival morphology of natural teeth. It has been reported that a digital technique is used to make a personalized healing abutment for peri-implant soft tissue shaping (Jodat, Ferrari M, Braegger U.A digital approach for one-step formation of the superior-implantation procedure with an induced CAD/CAM healing. J-procedure Res.2016; 60(3): 220) 223). The mode can acquire individualized gum-penetrating outline to a certain extent, but because it lacks the dental crown, influence the patient beautifully during moulding, pronounce, especially do not have the adjacent relation with adjacent tooth, can't form the extrusion effect to gum abduction clearance department soft tissue with adjacent tooth during moulding, be difficult to rebuild the gum nipple that lacks the tooth area and miss, easily lead to the front gum abduction clearance department to leave "black triangle" after the restoration, can't obtain the most ideal soft tissue aesthetic effect.
Therefore, it is highly desirable to provide a personalized abutment-crown integrated temporary prosthesis suitable for individual patients and consistent with the natural gum-penetrating contour of the teeth, so as to solve the above problems and obtain more natural and plump aesthetic effect of soft tissues around the implant.

The embodiment provides a specific application of the personalized abutment-crown integrated temporary prosthesis in aesthetic dental implant repair, which is as follows:
before shaping, the soft tissue shape of the maxillary anterior tooth area, the soft tissue edge position around the implant, the shape of the implant gum-penetrating cuff are different from those of the natural tooth and are not harmonious.
The temporary restoration is arranged on the dental implant through a titanium screw matched with the titanium substrate, and the application time of the personalized abutment-crown integrated temporary restoration is the time of the second-stage implant operation after the implant is implanted for 3-6 months and stable osseointegration is achieved.
Because the gum penetrating outline of the temporary restoration is obtained by mirroring the same-name natural tooth on the opposite side, the gum penetrating outline is more consistent with the gum penetrating outline of the natural tooth, the individualized shaping can be carried out on the soft tissue around the dental implant, the soft tissue around the dental implant is completely healed at the moment, and the gum recession is not easy to occur during the shaping, so that the soft tissue around the dental implant which is more close to the natural gum form (including the gum margin level, the near-middle gum papilla and the far-middle gum papilla) can be obtained, and the more ideal aesthetic effect of dental implantation restoration is achieved.
In the personalized abutment-crown integrated temporary restoration, the form of the same-name tooth on the opposite side of the missing tooth is copied by extracting CBCT data and mirrored to the missing tooth area to obtain the form of the temporary restoration (including the gum penetrating outline), and the integrated temporary restoration is obtained by cutting resin or ceramic material through computer numerical control and adhering the resin or ceramic material with a titanium substrate, so that the soft tissue around the dental implant can be molded conveniently, and the form of the gingiva more approximate to the natural tooth can be obtained.
The abutment-crown integrated temporary prosthesis solves the problems that in the peripheral soft tissue shaping process of the implant in the oral cavity American area, the difference between the gingival penetrating outline and the size of a finished healing abutment is larger than that of a natural tooth, the appearance is difficult to adjust and change, the soft tissue shaping effect is poor, and the tooth lack area lacks a crown in the shaping period, so that the appearance and the pronunciation of a patient are influenced; the temporary crown made of the manual stack-molding resin needs a patient to see a doctor for many times, and the temporary crown is repeatedly disassembled and assembled during the soft tissue molding period to influence the healing of the gum-penetrating cuff and the health of the soft tissue.
In conclusion, the invention obtains the individual abutment-crown integrated temporary prosthesis which is suitable for the individual patient and is consistent with the natural tooth gum-penetrating outline, and the prosthesis can be well applied to the dental implantation restoration treatment in the American area to shape the soft tissue around the implant.
The soft tissue contour which is harmonious and consistent with the natural gingival margin is formed by adopting the peri-implant soft tissue form which is formed by the personalized abutment-crown integrated temporary restoration.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
