AI Technical Summary

Technical Problem

Traditional alveolar bone augmentation distraction devices are large, inconvenient to operate, and highly invasive. Bone grafting surgery also carries risks and unpredictable bone formation results.

Method used

A miniature stretcher for horizontal widening of the alveolar ridge is designed, employing a structure of stretching bolts, a fixing plate, and a stretching plate. The stretching bolts are adjusted by threads to gradually expand the alveolar bone gap. Titanium metal is used to reduce trauma and achieve stable fixation.

Benefits of technology

It achieves horizontal widening of the alveolar bone, reduces surgical trauma, is easy to operate, has significant osteogenic effects, and shortens the time for bone increase, making it suitable for patients with weak alveolar bone.

Abstract

The utility model relates to the field of alveolar ridge operation tools, in particular to a miniature distraction type distraction device with an alveolar ridge widened in the horizontal direction, and adopts the technical scheme that the miniature distraction type distraction device with the alveolar ridge widened in the horizontal direction comprises a distraction bolt, a fixing plate and a distraction plate, according to the distraction device for the alveolar bone, the distraction bolt is screwed into the screw groove in the fixing plate in a threaded mode, a doctor can conveniently screw the distraction bolt to expand a split gap of the alveolar bone so as to achieve the purpose of bone distraction, and the distraction device for the alveolar bone has the advantages that the distraction bolt is screwed into the screw groove in the fixing plate in a threaded mode, so that the distraction effect is good, and the distraction effect is good. After the alveolar bone reaches the expanding thickness, the position of the bolt is kept, so that the bone is gradually formed in the gap, and then the fixing plate and the expanding plate are in rigid contact with the alveolar bone and the split gap and are firmly fixed, so that unstable bone stretching, retraction after expanding and the like are prevented, and the device is gentle to operate, small in force and free of excessive pain.
