Description
Technical Field
The invention belongs to the technical field of dental implants, and particularly relates to a method for manufacturing a dental crown or an abutment by using a biological anatomical structure healing scanning body.
Background
The dental implant is a tooth missing restoration method which is based on a lower structure implanted into bone tissue to support and retain an upper dental prosthesis. It comprises a lower supporting implant and an upper dental prosthesis. It adopts artificial material (such as metal, ceramic, etc.) to make implant (generally similar to tooth root form), and adopts the operation method to implant into tissue (generally upper and lower jaws) and obtain firm retention support of bone tissue, and utilizes special device and mode to connect and support the dental prosthesis of upper portion.
The healing abutment is an important connecting part of the implant and the dental prosthesis, has the functions of forming gum closure and forming gum cuffs, and the gum penetrating height, the material and the shape of the healing abutment all affect the health and the aesthetic effect of the implanted denture gums and cuffs. The existing finished abutment used clinically has few selectable forms and angles and limited adjusting and modifying range. The cross section of the abutment is usually circular, the shape of the abutment can not be completely consistent with the shape of the neck of a natural tooth, the problems of food impaction, inflammation and infection of gums and the like are easily caused, and the personalized function and aesthetic requirements of patients are difficult to be considered.
The later stage is planted to the tooth, needs scan the gum contour earlier after the gum shaping, then takes off and plants base station installation scanning rod or shift the pole and scan, or is scanning through impression draw mode, need install the healing base station again after the scanning is accomplished, dismantles many times and can cause the wound to the gum cuff of healing for doctor's work load is big, the patient must bear more misery, and scanning rod data is unique, can't realize individualized customization.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a method for manufacturing a dental crown or an abutment by utilizing a biological anatomical structure healing scanning body, and solves the technical problems that the existing healing abutment cannot be completely consistent with the tooth neck shape of a target tooth position, food impaction and gum inflammation infection are easily caused, wounds are easily caused to healed gum cuffs, the workload of doctors is large, a patient needs to bear more pain, how to utilize the biological anatomical structure healing scanning body to manufacture teeth and the like.
In order to solve the problems, the technical scheme of the invention is as follows: a method for manufacturing a dental crown or an abutment by utilizing a biological anatomical structure healing scanning body, comprising the following steps;
1) acquiring dentition data of a patient with a biological anatomical structure healing scanning body by an intra-oral scanning method, an impression method transferred to an extra-oral scanning method or a CBCT scanning method;
2) editing and manufacturing a database of the biological anatomical structure healing scanning body, numbering the database, and importing the database and the numbering into tooth design software;
3) importing the dentition data in the step 1) into the tooth design software in the step 2), and calling a database of a biological anatomical structure healing scanning body according to the number;
4) and editing the gingival contour according to the database information and designing and manufacturing a dental crown or an abutment.
Further, the biological anatomical structure healing scanning body comprises a scanning body part, a gum penetrating part and a connecting interface part which are sequentially arranged from top to bottom;
the appearance and appearance characteristics of the scanning body part are preset in a background database according to actual scanning requirements, and the position of the scanning body part is higher than the height of the gum after the healing scanning body is installed; the form of the gum penetrating part is consistent with the decomposition and section form of the anatomical crown close to the neck of the tooth at the required implant position, and the size of the gum penetrating part is determined according to the gum condition of a patient and the size condition of the repaired tooth; the shape of the connecting interface is matched with the structural shape of the target implant.
Further, the tooth design software is 3shape or EXO.
By adopting the technical scheme, the gum can be healed to the shape of the neck of the target tooth by the design of the gum penetrating structure, the biological anatomical structure of the tooth is restored as much as possible, and the problems of food impaction, inflammation and infection and the like are not easy to occur. The design of the scanning body part can realize the function of the scanning rod, avoid repeated disassembly and assembly, effectively reduce the workload of doctors and relieve the pain of patients. The shape of the connecting interface can be reasonably selected according to the structural shape of the target implant.
According to the invention, the individual custom editing of the database is carried out according to the individual condition of each patient, the gingival contour is not required to be scanned during scanning, and the patient can directly select from the database of the edited biological anatomical structure healing scanning body, so that the workload of a doctor is effectively reduced, the pain of the patient is relieved, and the stimulation to the oral mucosa is reduced.
Compared with the prior art, the invention has the advantages of reasonable structural design, simple process, easy operation, difficult occurrence of food impaction and inflammation infection, effective avoidance of wound caused to healed gum cuffs, reduction of workload of doctors, alleviation of pain of patients and the like.
