Description

Multifunctional abutment for dental implant healing scanning, operation method thereof and special carrier

Technical Field

The invention relates to the technical field of dental implants, in particular to a multifunctional abutment for healing of a dental implant, an operation method thereof and a special carrier.

Background

The existing dental implant technology is mature day by day, the popularity is improved year by year, the convenience brought by the dental implant technology for patients is unprecedented, and the dental implant technology has no replaceable function on the function recovery.

Through clinical verification and with the deepening of clinical application and research, people find that the implant repairing process has the following defects:

1. in the existing implant, an implant is firstly implanted into an alveolar bone, and a healing abutment is inserted or fixed to an implant interface part by using a screw for gum shaping after an implant operation. After the gum is shaped, the repair process of clinical oral treatment can be completed by using an oral impression technology. The traditional oral impression technology is that a corresponding closed type or window-opening type transfer rod is installed on an intraoral implant, the intraoral condition is transferred to the outside of an oral cavity, a plaster mold in the oral cavity is copied, then a scanning base table or a scanning rod is inserted into the plaster mold, intraoral data is obtained by scanning the plaster mold and the scanning base table, then the permanent repairing base table and the dental crown are designed and manufactured through CAD/CAM, the healing base table needs to be taken down again clinically, and the final repairing base table and the dental crown are installed to complete the whole repairing process.

Above-mentioned traditional mould of getting and restoration process need relapse dismouting different grade type base station or transfer pole many times, and not only the process is loaded down with trivial details to each restoration process all need be operated by the clinical dentist who plants the restoration experience for many years, prevents that inaccurate, the not condition of taking one's place of intermediate link from appearing and leading to the doctor to need repeat this process. Therefore, the pain and the treatment cost of the patient are increased, and on the other hand, the transfer process in the later stage of the planting can be mastered by a dentist with years of clinical experience, so that the requirements on the experience of the dentist are increased, and the operation time of the dentist is increased.

2. In the traditional clinical oral restoration, the specification of an implant is selected according to the gap of a missing position in the mouth of a patient, generally, the specification of the dental implant is divided into a micro implant, a standard implant and a wide implant, the implant with different specifications is selected to be implanted relative to the gap of the missing position in the mouth, a plaster model is made by an oral impression technology, and then the direction, the position and the intraoral data of the implant are obtained by a box-type scanner/a desk-type scanner outside the mouth; or inserting the intraoral scanning rod corresponding to each type of implant into the intraoral implant, and acquiring the direction, the position and intraoral data of the implant by using an intraoral scanner.

The above-mentioned clinical dentist in traditional impression taking or intraoral scanning should reserve accessories such as healing base station, transfer pole and the substitute of each model implant, and after having gathered patient intraoral data, need install the healing base station that corresponds with the implant again, make implant peripheral gum moulding.

3. Specific specification and model can't be judged from the outward appearance to traditional implant scanning rod, and the clinician puts into the implant after confusing scanning rod model number easily by mistake, and measured intraoral data can't use, can cause whole repair process's failure.

4. After the existing healing abutment is installed on an implant, through recovery and growth for a period of time, the gingiva usually covers and wraps the healing abutment, and when the final healing abutment is installed in the later period, a clinician needs to reopen the gingiva at the position, so that the pain of a patient and the treatment cost are greatly increased.

5. In the existing oral implant restoration, a healing base station for restoration is relatively small, so that accurate and effective restoration can be realized in various oral environments. But also because the healing abutment itself is too small, the following risks are liable to occur: if there is unreliable fixation during the surgical procedure, detachment can occur, the patient can present a swallowing reflex, which can lead to the risk of this component entering the patient's throat or being inhaled into the respiratory tract, and these potentially risky and harmful events are most likely to occur during the placement or removal of the abutment within the patient's mouth by the clinician.

6. The healing abutment may also be unstable or mishandled during transport outside the mouth (e.g., during removal of the abutment from its sterile packaging and transfer of the abutment into the patient's mouth) and may fall out. When the base is made of a metal member, the base may be deformed after being dropped or contaminated by time in a harmful environment, and it is necessary to re-sterilize and sterilize the base. When the abutment material is a ceramic material, the abutment material is likely to be broken after being dropped, and thus the patient may have a prolonged visit time. This not only causes inconvenience to the patient, but also creates a corresponding additional cost.

Aiming at the defects in the prior art, the novel scheme design is started from the base station structure in advance and matched with related auxiliary facilities.
