Embodiment 1

[0025] Step (1). Confirm the single tooth loss of the maxillary first molar through oral clinical examination, and analyze the bone height of the patient's edentulous area by oral CBCT to be 8mm, width 9mm, type 2 bone, jaw-gingival distance 6mm, and gingival thickness 3mm;

[0026] Step (2), according to the patient’s missing tooth area data obtained in step (1), use exocad software on the computer to design personalized zirconia implant body c thread form, implant body c length and diameter, gingival penetration The height and shape of part b and the height of abutment (such as figure 1 Shown);

example 1

[0027] The design data of Example 1 are as follows: the implant body diameter is 5mm, the body length is 7.5mm, the body shape is columnar, the transgingival height is 2mm, and the abutment height is 5mm.

[0028] Step (3), according to the personalized implant data designed in step (2), use KavoArcticaEngineCAM grinder to process medical zirconia materials to obtain personalized zirconia implants;

[0029] The medical zirconia material contains 4.5% yttrium oxide by mass;

[0030] Step (4). Place the processed personalized zirconia implant in a crystallization furnace at 1440°C for 12 hours, then cool the sintered implant at 10°C / min to 900°C, and then at 5°C / min Cool down to 600°C, then naturally cool to room temperature, and finally perform mechanical polishing on the transgingival part b and upper abutment a of the implant after cooling;

[0031] The mechanical polishing is to polish the implant transgingival part b and abutment a with emery silica gel polishing wheel, and the rou...

Embodiment 2

[0037] Step (1). Confirm the loss of a single maxillary anterior tooth through oral clinical examination, and analyze the bone height of the patient's edentulous area by oral CBCT to be 15mm, width 7mm, type 2 bone, jaw-gingival distance 8mm, and gingival thickness 4mm;

[0038] Step (2), according to the patient’s missing tooth area data obtained in step (1), use exocad software on the computer to design personalized zirconia implant body c thread form, implant body c length and diameter, gingival penetration The height and shape of part b and the height of abutment (such as figure 1 Shown);

Abstract

The invention discloses a preparation method for a CAD / CAM individuality zirconia one-stage implant. The method comprises the steps of firstly, analyzing the bone substance, bone mass, the distance between the jaw and the gingiva, and the thickness of the gingiva of the anodontia region of a patient to obtain data, using the exocad software for designing the thread form of an implant body, the length and diameter of the implant body, the height and the form of the gingiva through portion and the abutment height, then adopting a CAM grinding mill for machining medical zirconia materials to obtain a zirconia implant, placing the zirconia implant into a crystal oven to be sintered, conducting cooling to reach the normal temperature, then mechanically polishing the gingiva through portion of the implant body and the upper abutment, conducting surface abrasive blasting roughing treatment on the inner section of an implanted bone, and finally conducting cleaning and sterilization. The CAD / CAM technology is utilized for manufacturing the individuality one-stage implant which is better suitable for anodontia patients on different hardness tissue conditions, and the one-stage implant can be more widely applied compared with traditional implants.

Description

Technical field [0001] The invention belongs to the field of dental implants, and specifically relates to a method for preparing a CAD / CAM personalized zirconia one-stage implant. Background technique [0002] Since titanium implants have been used in the restoration of oral tooth loss, a high success rate has been achieved. However, titanium implants have such aesthetics as the thinner gums that easily reveal the metal color of the implant and the gingival recession after implantation leads to metal exposure. Problem: At the same time, titanium particles may also enter adjacent tissues or lymphatic tissues, and titanium metal may also be a potential allergen. Therefore, patients prefer non-metal implant restorations. In addition, the soft and hard tissue conditions of the patient's edentulous area are the same, and there is a greater demand for personalized implants. [0003] Zirconia materials have been widely used in orthopedic surgery and dental crown and bridge restorations,...
