Description

Adjustable Saddle Dental Implants

technical field

The invention relates to a dental implant, especially an adjustable saddle dental implant for implanting in the alveolar bone of the human oral cavity and providing an artificial crown for installation thereon.

Background technique

Regardless of whether the early artificial dental implants were one-stage or two-stage structures, their holding force depended on the result of osseointegration of the implant site in the alveolar bone. Taking the two-stage dental implant as an example, its structure includes a root part and a tooth part. The root part is used to be screwed into the alveolar bone of the human oral cavity. The screw is arranged in the screw hole with the opening of the root part facing upwards, and the upper end of the tooth part of the abutment protrudes outside the gingival flap outside the alveolar bone, and is used for assembling an artificial crown.

Clinically, the alveolar bone where the dental implant is implanted should preferably have a height of more than 10mm and a width of more than 5mm. The implant operation of the dental implant is relatively safe and stable. However, the early artificial dental implants only combined their tooth root parts with the alveolar bone. Because of the atrophy of the alveolar bone caused by the length of time for each implanted person to lose teeth before the implant, or the bone of the alveolar bone The alveolar bone condition of each dental implant is different due to the influence of density or changes in the position of the sinuses. Often due to poor bone quality, it is difficult to provide a firm combination of artificial dental implants, and the expected osseointegration results cannot be achieved. Or, after a period of occlusal action or external force of the artificial crown or bridge, the dental implant and alveolar bone supporting the artificial crown or bridge are prone to loosening, resulting in Overall failure of dentures connected to artificial crowns or bridges, etc.

In order to solve the problems that the existing artificial dental implants are difficult to apply to the alveolar bone with poor bone quality in dental implant surgery, and the danger of artificial dental implant operation and poor postoperative firmness. The designer has previously proposed a dental implant, which includes the root of the implant, the abutment and the fixed overlay. Between the parts, and the opposite sides of the fixed cover form a first wing part and a second wing part respectively, and the inclination angles of the first wing part and the second wing part are set. The implant root of the dental implant can be implanted in the alveolar bone in the human oral cavity for osseointegration, the abutment protrudes out of the gingival flap, and is used to fix an artificial crown, and the fixed overlay is based on its relative The inclined first wing part and the second wing part on both sides cover the surface of the cortical bone wall of the alveolar bone surface and are fixed with locking screws, thereby providing a device that can simultaneously be implanted. It is a dental implant with multiple functions such as being firm and not loose in the alveolar bone, easy to operate, low cost, and safe.

After the designer completed the above-mentioned dental implant design, it can be effectively proved clinically that the dental implant can provide enough strength to support the artificial crown, and quickly rebuild the osseointegration conditions of the implant area, especially in the state of poor bone quality Under the circumstances, such as the dangerous area with insufficient bone thickness at the bottom of the maxillary sinus, etc., the area where the implant reconstruction cannot be completed with the early one-stage or two-stage artificial dental implant does have substantial benefits.

However, clinically, the degree of bone atrophy of each patient is different, and the angle between the wing parts on both sides of the fixed overlay is preset for the anterior dental implant, and sometimes the angle is inappropriate, that is to say, When considering the position and direction of the optimal abutment tooth parts required for occlusion, after the implant root of the dental implant is inserted into the alveolar bone through the cortical bone hole on the surface of the alveolar bone, the first wing and the second The pre-set angle of the two wing parts cannot fit correctly with the cortical bone wall on the surface of the alveolar bone, resulting in the possibility that the locking screw that passes through the first wing part or the second wing part and locks to the alveolar bone may be partially suspended , or the depth of locking into the alveolar bone is insufficient, resulting in the defect that the locking screw cannot operate correctly, resulting in insufficient locking ability of the wing parts on both sides of the dental implant, unable to provide the root of the dental implant and the alveolar The problem of the stabilizing force required for the period of bone osseointegration. For this, further improvement is necessary.
