Description

Oral implant positioner with alveolar ridge bone shape and form measuring function

Technical Field

The invention relates to the technical field of medical instruments, in particular to an oral implant positioner with an alveolar ridge bone shape measuring function.

Background

After the tooth is lost, there are many restoration methods, and the implanted tooth is gradually becoming a mainstream choice. The basic principle of the oral implantation technology is that a cylindrical (or conical) artificial tooth root with threads is implanted into an alveolar bone, after an implant is combined with the bone, an abutment is connected to the upper end of the implant, and the tooth crown is repaired. It can be seen that the basis of a dental implant is that there must be a sufficient amount of bone, and the most critical factor in determining success or failure of the implant is whether the implant can obtain sufficient bone support. The implanted implant needs to have a certain thickness of bone wrapping on each surface, otherwise the implant can fail. However, as the alveolar bone is continuously absorbed, atrophied, and remodeled after the loss of teeth, the bone appearance becomes irregular, and individual differences are great. The bone morphology structure (mainly height and width) of an alveolar ridge in a tooth missing area is mastered, which is a precondition for tooth implantation and is a basis for selecting the thickness and length of an implant; after the implant is selected, the correct implantation direction, pointing to the bucco-lingual midpoint of the bone, is the key to ensure that the bucco-lingual side of the implanted implant has a uniform thickness of bone.

Although the width and height of the bone can be measured on the CT image by CT (common oral CBCT) examination, how to correspond the measurement position on the CT digital image to the oral cavity of the patient is difficult to solve. The best solution at present is to establish a digital model based on CT data, select a suitable implant, make an individualized 3D printing implant guide plate, and determine a suitable implant implantation direction by tooth or bone surface positioning. However, the 3D printing implant guide plate is expensive to manufacture, which greatly increases the cost of the implant and the economic burden of the patient, and thus is difficult to be widely applied. Especially, in a basic oral clinic, CT cannot be shot to perform alveolar bone three-dimensional measurement even before dental implant operation, and a 3D printing implant guide plate is manufactured, so that the development of a positioner which is low in price, has universality, measures the morphology of alveolar ridge bones and assists in implant guiding has great research significance and application value.
