Universal auxiliary registration device for dental implant data
The invention relates to the technical field of dental technology, in particular to a
universal auxiliary registration device for dental implant data.
In the virtual plan of dental implant, it is necessary to register the optical scanning data of
the patient's mouth with the cone beam CT data, so that they can obtain the same three
dimensional coordinate system. In the actual process of registration, due to the large
number of missing teeth or the large number of metal restorations or implants in the
mouth of some patients, the optional registration feature points in the cone beam CT
images are insufficient or covered by metal artifacts, which interferes with the normal
registration process. At present, the following procedures are used in clinical data
registration in this kind of environment:
1) When a patient visits a doctor for the first time, a cone beam CT is taken, and the
doctor judges whether the patient can perform implant surgery according to the imaging
examination, and if so, enters the next step.
2) The doctor made the patient's oral impression and poured the plaster model.
3) The technician center makes the radiation template of acrylic resin material according
to the plaster model in the patient's mouth, and shoots cone beam CT or performs optical
scanning on the radiation template.
4) When the patient goes to see the doctor for the second time, he/she will be wearing a
radiation template to shoot the second cone beam CT.
) The technician center will register the cone beam CT taken by the patient for the
second time with the image or scanning data of the radiation template.
It can be seen that through the prior art, the patient needs to take cone beam CT twice,
which increases the radiation exposure of the patient in a short time. In addition, the
radiation template made of acrylic resin has the following shortcomings: personalized
production, extra production time, difficult fitting, multi-position, uneven mixing of
acrylic resin, bubbles inside and so on. Therefore, the existing technology needs to be
improved.
In order to solve the above technical problems. We propose a universal auxiliary
registration device for dental implant data.
The main purpose of the present invention is to provide a universal auxiliary registration
device for dental implant data, which can effectively solve the problems mentioned in the
background.
In order to achieve the above purpose, the technical scheme adopted by the invention is
as follows:
A universal auxiliary registration device for dental implant data, which comprises a main
body, characterized in that the main body is provided with retention grooves for placing
and fixing upper and lower dentition, outline reference structures for providing outline
reference for registration inspection are arranged outside the main body, and the number
of retention grooves is two and respectively arranged on the main body. The main body
located at one side of the retention groove is also provided with a tongue containing
structure which is a blind groove conforming to the shape of the tongue, the retention groove is provided with a plurality of through grooves with different sizes, and two sides of the retention groove are provided with retaining structure. The retaining structure is used for increasing friction between the retention groove and silicone rubber in the retention groove. the main body is also internally provided with a radiation marking point for avoiding interference of metal artifacts in CT data to radiation marking points. the radiation marking point is a cylinder with a diameter of 2.5mm and a height of 2.5mm.
The retaining structure is of convex structure.
Furthermore, the radiation mark points are made of zinc oxide.
Furthermore, the radiation mark points are made of silicon nitride.
Furthermore, the radiation mark points are made of barium sulfate.
Furthermore, the radiation mark points are made of zirconia.
Furthermore, the retaining structure is a nail-shaped protrusion.
Furthermore, the retaining structure is a rounded rectangle.
Compared with the prior art, the invention has the following beneficial effects: the
interference of metal artifacts in CT data on radiation mark points can be avoided, which
provides enough and clear registration feature points for data registration. In addition, the
device is of universal design, which avoids personalized production flow and saves extra
production time. Patients can complete the acquisition of CT data required for registration
when wearing the device at first diagnosis, without taking CT for many times, thus
reducing the radiation suffered by patients.
