Abstract

The invention discloses a pinhole bone extruding and expanding device, belonging to medical apparatus and instruments. The pinhole bone extruding and expanding device comprises a stabilizing part (1), a screwing part (2), a self-tapping thread part (4), a second thread part (5), a guide pillar (6) and a sharp head part (7), wherein the stabilizing part (1) is cylinder-shaped, the screwing part (2) is a non-round-section cylinder, the small end of the self-tapping thread part (4) is connected with the second thread part (5), the second thread part (5) is a cylinder, and is provided with external threads, the guide pillar (6) is cylinder-shaped, and the sharp head part (7) is tri-prism-shaped. With the adoption of the pinhole bone extruding and expanding device, the placement operation of an implant can be realized with the minimal trauma or no trauma.

Description

technical field [0001] The invention relates to a medical device, in particular to a pinhole bone extrusion reamer (referred to as a pinhole bone extrusion reamer). Background technique [0002] After the patient's dentition is defective or missing due to various reasons, the thickness of the patient's alveolar ridge or alveolar process, that is, the thickness of the labial tongue / palatin direction or the thickness of the buccal tongue / palatin direction will change more or less in one way or another. As the tooth loss time increases, the bone thickness of the alveolar crest tends to become thinner. Female patients are more obvious than male patients, and those who have removable dentures are more obvious than those who do not wear them. The problem of insufficient bone mass. Considering the special requirements of aesthetic restoration (individual patients), for cases of lack of lip-glossal / palatal thickness, doctors will recommend patients to undergo bone augmentation surg...
