Problems solved by technology

However, the distraction implants are all dumbbell-shaped after being finalized, and the delivery loops that are directly connected to the restoration abutment and bear the occlusal force are relatively short and have poor load-bearing capacity; the fixed loops that remain permanently in the jawbone are an independent Metal structure, if the implant fails due to infection or loosening, it will be difficult to remove

Embodiment Construction

[0022] refer to figure 1 , figure 2 , The distraction dental implant mainly includes a fixed ring 2, a delivery ring 1, a connecting bolt, a distraction bolt, and the connecting surfaces of the delivery ring 1 and the fixing ring 2 are connected to form a complete implant. The upper end of the delivery compass 1 has a shoulder 3 for supporting the abutment 4 . In the present invention, the conveying collar 1 and the fixed collar 2 are cylindrical hollows with internal threads respectively along the central longitudinal axis, which can accommodate connecting screws, stretching screws, fixing screws or closing screws, and the height of the fixed collar 2 and the conveying collar 1 The ratio is 1:4 to 1:3, the diameter of the cylindrical hollow of the fixed band 2 is smaller than the diameter of the cylindrical hollow of the delivery band 1, and the bottom of the fixed band 2 is a closed structure.

[0023] In this embodiment, the connecting screw is a pan-head screw, the lowe...

Abstract

The invention relates to the field of an oral cavity medical appliance and discloses a bone stretching dental implant. The bone stretching dental implant is characterized by comprising a fixed sieve and a conveying sieve, wherein the conveying sieve and the fixed sieve are respectively provided with a cylindrical cavity provided with an internal thread along the center longitudinal axis, the cavity contains a coupling screw and a fixed screw or stretching screw, the height ratio of the fixed sieve to the conveying sieve is (1:4)-(1:3), the diameter of the cylindrical cavity of the fixed sieveis smaller than that of the cylindrical cavity of the conveying sieve, and the bottom of the fixed sieve is of an enclosed structure.

Description

technical field [0001] The invention relates to the field of oral medical instruments, in particular to an osteodistraction dental implant. Background technique [0002] Dental implant restoration is a restoration method for missing teeth that emerged in the last century. Now it has become a popular trend in tooth restoration. Its application range includes single tooth loss, partial tooth loss, complete edentulous, jaw bone and facial defects; and , Dental implant restoration technology has gradually developed into a multi-interdisciplinary subject integrating medicine, materials science, mechanical technology and biomechanics. Dental implants are similar to natural teeth in form and function, with independent artificial tooth roots, beautiful and effective, and can solve problems that cannot be solved by traditional dental methods. However, when some jaws are seriously defective and the alveolar ridge is too low, traditional implants cannot be implanted; The length of th...
