Description
Technical Field
The utility model relates to the field of medical equipment, specifically an implant at once.
Background
1. The implants currently on the market are classified from the macro level:
(1) the method is divided into the following steps according to planting positions: bone level implants, gum level implants;
(2) the method is divided into the following steps according to the connection mode: an inner connection and an outer connection;
(3) the external shape is divided into: cylindrical, conical-column combined, column-cone combined, forward cone and reverse cone combined;
(4) the operation method comprises the following steps: a one-stage implant and a two-stage implant;
(5) the length of the implant is divided into: short implants (less than 7mm), general length implants (7-19mm), lengthened implants (greater than 19 mm).
2. Currently marketed implants are classified from microscopic:
(1) the method is divided into the following steps according to the form of platform butt joint: platform transfer and non-platform transfer;
(2) the neck part is divided into: straight constant depth micro-threads, straight depth gradient threads, straight micro-rough surface no-threads, straight smooth no-threads, right cone smooth no-threads, inverted cone smooth no-threads;
(3) the method is divided into the following steps according to the shape of the bottom: circular arc type, flat bottom type;
(4) the material according to the implant is divided into: ceramic, TA4G pure titanium, TC4 titanium alloy;
(5) the method comprises the following steps according to whether the implant is provided with a self-tapping groove: with and without self-tapping grooves.
In summary, current implants are formed from multiple combinations of the macro-and micro-classifications described above.
The prior art is analyzed from a microscopic perspective to have the following disadvantages:
although the existing implants basically meet various patients, the existing implants only exist in the meeting level, have excellent distance and have tiny defects, and the advantages of the mainstream implant products in the current market are combined as follows:
(1) bone level implant: the method can conveniently realize a plurality of repair modes in the later period, and is also a preferred choice for patients with poor bone quality;
(2) internally connecting the implant: the bone resorption can be effectively reduced in the long-term bone healing and loading processes after the implantation;
(3) the combined planting body of cone column type, positive cone back taper: has more convenient clinical operation and long-term load stability;
(4) two-stage implant: the method can conveniently realize a plurality of repair modes in the later period, and is also a preferred choice for patients with poor bone quality;
(5) general length implant: it is possible for each patient to use implants of more or less this length;
(6) body thread depth combination: has more convenient clinical operation and long-term load stability;
(7) implant with platform transfer: the bone resorption can be effectively reduced in the long-term bone healing and loading processes after the implantation;
(8) implant with micro-thread on neck: the bone contact area is increased, and the bone absorption is effectively reduced in the long-term bone healing process;
(9) TA4G pure titanium implant: the TA4G pure titanium material has excellent biocompatibility;
(10) implant with self-tapping groove: has self-tapping property for implantation and convenient clinical operation.
In conclusion, the advantages of the current implants are combined, and the popular trend of the planting cannot be compensated:
(1) because of the implant is for permanent implantation and load, requires higher intensity, even if the patient chews for a long time and bears a burden the in-process like this, some mechanical complications appear, if the intensity of implant is higher than the restoration subassembly, can avoid taking out the implant from the sclerotin, bring very big wound and injury in the heart for the patient, only need change the restoration accessory on implant upper portion can.
(2) Although the neck of the implant comprises the micro-threads, the shape of the implant body is not effectively combined with the micro-threads, so that an ideal choice cannot be realized for a patient who requires immediate repair or a patient who has poor bone quality, only one type of implant is close to the requirement of the patient at present, but the micro-threads of the neck and the threads of the body are in a disconnected distribution, smooth transition connection of the micro-threads and the threads of the body is not realized, certain negative influence is caused on clinical operation, and the interrupted thread form of the product also has certain negative influence on the bone reconstruction and healing period.
(3) At present, only one is close to patient's demand planting body, and its self tapping groove has certain defect, and at the in-process of implanting, fail to provide sufficient storage space for tiny bone bits, lead to the implantation process probably to lead to the increase of implanting the moment of torsion, simultaneously because the bone bits do not obtain sufficient storage space, will lead to the in-process of implanting back bone healing, do not have better blood circulation space, finally influenced bone healing's time and effect.
