Description
Technical Field
The utility model relates to a retention nail for guiding an oral implant guide plate, and belongs to the technical field of oral implant.
Background
Tooth implantation is one of main methods for repairing lost teeth, an accurate implantation position is the basis for realizing functional and aesthetic repair, and a digital guide plate can accurately transfer a virtual implant position planned before an operation to an actual implantation operation position and is an important carrier for realizing optimal implantation.
The digital guide plate guided planting has the advantages that the average error of the shoulder part of the implant is 0.99mm (0-6.5 mm), the average error of the root tip part is 1.24mm (0-6.9mm), the average angle deviation is 3.81 degrees (0-24.9 degrees), the average vertical deviation is 0.46mm (-2.33-4.20mm), and the precision of the guide plate is better than that of a person without the guide plate.
The digital implant guide plate can be divided into a bone support type, a mucous membrane support type, a tooth support type and a tooth-mucous membrane mixed support type according to the support modes, the guide plates of different support modes are different in the aspect of implantation precision, wherein the tooth support type > the tooth-mucous membrane mixed support type > the mucous membrane support type > the bone support type, for a patient without a dental jaw, the digital guide plate is often supported by the mucous membrane in the oral cavity, certain pressure is required when the mucous membrane support type guide plate is in place, the mucous membrane has the flexibility when being pressed, the flexibility of the mucous membrane enables the guide plate to generate certain mobility in the process of placing, the digital guide plate can cause the deviation of the position of the guide plate by slight movement, and finally the implantation precision of the implant is influenced, wherein the thickness of the mucous membrane is also the main factor influencing the implantation precision of the mucous membrane support type guide plate, and the deviation of the neck of the implant of a thick mucous membrane patient is 1.04mm, while the thin mucosa is 0.08 mm, we still need to hold a careful attitude for the accuracy of the mucosa-supported guide plate.
Turbush's research shows that, in the aspect of neck skew and apex portion skew, the precision of mucous membrane support formula baffle is less than the tooth and supports the formula, and the error that the tooth supported formula baffle is minimum, therefore, to the design of digital baffle, firm tooth is the assurance of digital baffle planting precision, and how to realize the tooth on the patient of edentulous jaw and support formula digital baffle probably is the new direction that promotes the baffle precision.
