Description

One-piece dental implant

The present invention relates to a dental implant, and more particularly to a one-piece dental implant in which an implant is integrally connected to the abutment body.

In general, no matter whether it is aging or accidental impact, the tooth defect, if it is not repaired and complexed for the damaged tooth, will affect the occlusion and chewing function, and even cause the back tooth to fall forward, bone atrophy and face shape change, etc. Aftereffects. Among the various methods for repairing tooth defects, "artificial implants" have the advantages of not damaging healthy and natural teeth on both sides, easy to clean, no foreign body sensation, and good aesthetics after implantation, so that artificial tooth implants can be used to repair dental defects. The number of patients has increased year by year.

The term "artificial implant" refers to a dental implant made of medical grade materials (such as titanium or ceramics) that is surgically implanted into the alveolar bone of a patient and then subjected to bone integration before crowning. Installation, the patient is restored to the original teeth to meet the needs of chewing and aesthetic functions; wherein the dental implant comprises an implant and a table body, the dental implant is implanted into the patient by the implant In the alveolar bone, the abutment body provided at one end of the implant is used for positioning and positioning the crown.

Currently, clinically used dental implants can be broadly classified into three categories: one-piece dental implants, two-piece dental implants, and three-piece dental implants; "Implant" means a dental implant in which the implant is integrally connected to the abutment body, compared to a two-piece dental implant and a three-piece dental implant that must be screwed or snapped between the components. The one-piece dental implant does not have to worry about loosening or breaking of the joint between the implant and the abutment body, and does not need to perform a second operation, which can improve the operation efficiency and reduce the pain of the patient.

For example, US Patent No. 5961328 "Dental implant", Republic of China Announcement No. M416449 "Artificial Dental Implant", No. M438247 "Dental Artificial Implant Improvement" and No. M457533 "Threaded Optimum Dental Implant" , both disclose dental implants belonging to the aforementioned "one-piece dental implant", and the conventional one-piece dental implant has a coaxial axis with the central axis of the implant and the abutment body. state. However, since the teeth in the anterior region are generally thin and angled, the center of the abutment body is implanted in the patient's alveolar bone with the aforementioned conventional one-piece dental implant. The axis will not match the forward tilt angle of the tooth, so that the installed crown is prone to tilting and the implant fails. Therefore, the conventional one-piece dental implant can only be applied to the implant operation in the posterior region and cannot be applied. Dental implant surgery in the anterior region has the disadvantage of poor practicality.

To this end, please refer to Fig. 1, which is a conventional one-piece dental implant 9 disclosed in the Patent No. M390130, "Single-piece angle implant" patent, which is a conventional one-piece type. The dental implant 9 is directly connected to an inclined support frame 92 at the end of the implant body 91, so that the implant body 91 and the central axis of the support frame 92 have an angle α of 5 to 25 degrees, and The outer surface of the support frame 92 defines a recessed hole 93 extending along the central axis of the implant body 91; thus, a one-piece dental implant 9 having an appropriate tilt angle can be selected according to the use requirement. The implant body 91 is anchored to the concave bone hole B by the tool to anchor the implant body 91 to the alveolar bone B of the anterior region of the patient. After the wound is healed, the crown C is mounted on the support frame 92. To complete the implant surgery in the anterior region.

However, the conventional one-piece dental implant 9 must be provided with several specifications to suit the implanting needs of various tilting angles, which not only causes inconvenience in material management of the medical unit, but also causes pressure on the manufacturer to stock up; Although the conventional one-piece dental implant 9 can be applied to the dental implant surgery in the anterior region, but can not be applied to the dental implant surgery in the posterior region, it still has the disadvantage of still being inferior in practicality.

For the above reasons, the conventional one-piece dental implants have to be improved. Want.
