Abstract
The utility model discloses a composite guide plate for guiding tooth half-cutting operation and planting, which comprises a plate body, a dental floss dividing indication groove, a planting hole and an observation window, wherein the dental floss dividing indication groove, the planting hole and the observation window are arranged on the plate body, the plate body is sleeved outside teeth of a patient, the dental floss dividing indication groove is arranged at the root position of teeth to be half-cut, the planting hole is arranged above a planting site of the teeth to be planted, and the observation window is distributed on two sides of the dental floss dividing indication groove and the planting hole. The planting hole is a cylindrical channel with the diameter of 3 mm. The utility model fits the digital information of CT and intraoral dentition by a numerical technology, can define the bifurcation position before operation, and sets the dividing dental floss indication groove on the plate body, so that the accuracy is high, the vibration is small, the dental half-cutting and the implant implantation operation are accurately and rapidly implemented in a minimally invasive way, and the pain of patients is reduced.
Description
Technical Field
The utility model relates to the technical field of dental implant correlation, in particular to a composite guide plate for guiding dental hemitomy and implantation.
Background
Invasive periodontitis progresses rapidly, and has poor therapeutic effects, often resulting in tooth loss and severe alveolar bone resorption. Such patients need to be implanted with implant restoration, in which diseased dental tissue is removed, bone mass is increased, and then implant teeth are implanted. Therapeutic procedures include dental hemigrafting, bone augmentation surgery and implant implantation surgery.
The tooth half-cutting is mostly used for mandibular molar, the alveolar bone of a root is seriously damaged, the bone absorption of a root bifurcation is obvious or the affected tooth which is not reserved by the dental crown and the dental root of a serious part of the tooth body lesion, and the affected tooth needs to be longitudinally separated from the root bifurcation, so that the part with serious lesion is extracted. Because the position of root bifurcation cannot be directly seen in the mouth, the traditional tooth half-cutting operation searches for the tooth dividing position through the inspection and doctor experience, and errors are easy to occur: excessive tooth excision and insufficient repeated excision increase operation wounds and damage bone tissues of root bifurcation.
On the other hand, after undergoing a tooth half-cutting operation, the original tooth-missing space of the adjacent tooth is enlarged, the implant implantation site and the traditional implantation site are changed, the implantation site is required to be evaluated immediately in operation along with the loss of bone mass, and meanwhile, errors are increased when the implantation nest is prepared on the surface of the defective bone by free hands.
Disclosure of Invention
The utility model aims to provide a composite guide plate for guiding tooth half-cutting operation and planting, which is accurate, quick and simple in structure, and aims to solve the problems in the background technology.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides a compound baffle of guide tooth half-cut art and planting, includes the plate body and sets up branch dental floss instruction groove, planting hole and the observation window on this plate body, the plate body cover is established outside patient's tooth, divides the dental floss instruction groove to set up the root position at waiting half-cut tooth, and the planting hole sets up the planting site top at waiting to plant the tooth, and the observation window distributes in the both sides that divide dental floss instruction groove and planting hole.
Further, the planting hole is a cylindrical channel with a diameter of 3 mm.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model fits the digital information of CT and intraoral dentition by a numerical technology, can define the bifurcation position before operation, and sets the dividing dental floss indication groove on the plate body, so that the accuracy is high, the vibration is small, the dental half-cutting and the implant implantation operation are accurately and rapidly implemented in a minimally invasive way, and the pain of patients is reduced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
in the figure: 1-a plate body; 2-floss dividing indication groove; 3-planting holes; 4-viewing window.
Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
The utility model provides a compound baffle of guide tooth half-cut art and planting, includes plate body 1 and divides dental floss instruction groove 2, planting hole 3 and observation window 4 of setting on this plate body 1, plate body 1 cover is established outside patient's tooth for fix the tooth that remains in the art, reduce its influence that receives mechanical vibration, divide dental floss instruction groove 2 to set up at the root position of waiting half-cut tooth, be used for confirming the root position of waiting half-cut tooth, planting hole 3 setting is in the planting site top of waiting to plant the tooth, be used for instructing the planting site, planting hole 3 is the cylinder passageway that diameter is 3mm, is used for locating implantation site and implantation direction. The observation windows 4 are distributed on two sides of the dental floss dividing indication groove 2 and the planting holes 3 and are used for observing the placement condition of the plate body 1.
The manufacturing method of the composite guide plate for the seed guide tooth half-cutting and planting comprises the following steps: firstly, by fitting tooth model scanning information and contemporaneous CT data, separating and marking the tooth root condition of the tooth to be subjected to the tooth half-cut operation on the CT; the tooth counting dental floss is designed on the principle that the bone wall of the bifurcation is not broken and the tooth tissue at the bifurcation is reserved as much as possible; after the simulated tooth extraction, a prosthesis is designed according to the new tooth deficiency gap and the jaw tooth alignment condition, and a plate body 1 with a dental floss dividing indication groove 2, a planting hole 3 and an observation window 4 is designed and printed according to the position of the prosthesis.
According to the utility model, the position of the dental floss is definitely calculated through fitting of preoperative digital technical information, so that the accuracy of dental floss dividing operation is improved, the operation speed is increased, and the wound is reduced; the plate body 1 has the fixation function similar to a splint for periodontal loose teeth, prevents cutting vibration from damaging residual periodontal tissues, and the implantation holes 3 have the condition of preventing drill pins from sliding and inaccurate implantation caused by alveolar bone damage when the implant is implanted.
