Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings.

[0045] refer to Figure 1 to Figure 6 , a kind of manufacturing method of the dental implant surgery guide plate of non-total tooth loss, described manufacturing method comprises the following steps:

[0046] (1) CT data collection: Take CT images of the patient's oral cavity. In order to ensure the accuracy of bone reconstruction, the scan layer thickness is not greater than 1 mm.

[0047] (2) Three-dimensional bone model reconstruction: Use three-dimensional reconstruction software such as Mimics to reconstruct the bone model (including teeth) of the patient's oral cavity, and the reconstruction model also includes the mandibular canal and maxillary canal. Such as figure 1 shown.

[0048](3) Design a preliminary implant plan (including the number, position, and size of implants) based on biomechanics and patient bone conditions (bone density, bone height and thick...

Abstract

The invention discloses a method of making a partial-anodontia tooth implantation surgical guide plate, which comprises the following steps of: (1) acquiring CT data; (2) reconstructing a three-dimensional model of a skeleton; (3) designing an implantation scheme according to biomechanics and skeleton conditions of a patient; (4) designing an analog column for determining an implantation nest according to a position of an implant; (5) subtracting the analog column of the implant from the three-dimensional model of the skeleton by using Boolean subtraction to obtain a preliminary position of the implantation nest; (6) using a light-cured resin to form a skeleton model with a preliminary implantation nest through a rapid forming method; (7) adjusting the skeleton model with the preliminary implantation nest on the skeleton model; (8) inserting an analog implant into the implantation nest of the skeleton model; (9) making a gypsum model inside the oral cavity of the patient; (10) obtaining an analog soft tissue of an edentulous part; (11) repairing false teeth; and (12) making the surgical guide plate. The invention can be reasonably adjusted by an implantation doctor, and has accurate positioning and good practicability.

Description

technical field [0001] The invention relates to a method for making a guide plate for dental implant surgery with incomplete tooth loss, which provides a guide plate for restoration surgery for missing teeth to realize precise implant surgery. Background technique [0002] In the 1950s, Professor Branemark of the University of Gothenburg, Sweden, known as the originator of dental implants, invented the combination of titanium metal and bone and proposed the concept of "osseointegration", thus laying the foundation for the development of modern implantology. Artificial dental implants are implanted in the alveolar bone of the edentulous area, which is a titanium metal root that can be well integrated with the bone, that is, an implant. After 3-6 months of over-synthesis, the titanium metal tooth root is fully integrated with the surrounding gum bone , become a solid artificial tooth root that can withstand huge occlusal force, and then connect the artificial tooth crown made ...
