Abstract: A bone augmentation product for guiding bone tissue regeneration includes a soft tissue barrier membrane in the form of a soft sheet, and a tissue-regeneration guiding material being integrally molded to one side of the soft tissue barrier membrane. The tissue-regeneration guiding material may be collagen for directly filling in a defective area on a tooth bed or an area on a bone requiring osteogenesis to thereby simplify the procedures and reduce the difficulty in a surgery.

Abstract: A tooth orthopedic appliance has a bracket, a plurality of middle supporting portions and a plurality of side wing portions. The bracket is connected to a surface of the tooth, wherein a base is provided on a middle part of the bracket. A main wire trench is utilized to locate a correcting wire. The plurality of middle supporting portions are located respectively at a middle part of two protruding portions of the bracket, wherein the middle supporting portions are parallel to the bracket and perpendicular to the main wire trench. A wire holding slot is formed in between the bracket and every middle supporting portion for hooking a holding wire. A notch is defined by sidewalls of the middle supporting portions and the side wing portions in order to locate the holding wire for locking a top portion of the correcting wire such that an unfastened condition is formed.

Abstract: An orthodontic pin includes a pin body and a fastening member screwed into the pin body. An elastic element is connected at an end to the orthodontic pin by extending the fastening member through a ring provided at the end of the elastic element before screwing it into the pin body. When the elastic element becomes loose due to any change in the position of a tooth being corrected, it can be determined the elastic element needs replacement. Since the fastening member can be easily loosened from the pin body of the orthodontic pin, the elastic element can be conveniently removed from the pin body to facilitate quick replacement of the elastic element.

Abstract: A gum adjusting and shaping device mainly includes an outer die, an abutments of implanted tooth detachably put in the outer die, and a cap screw received in the abutments of implanted tooth for fixing the latter and the outer die to an artificial implant previously implanted in the tooth socket bone. The outer die is a cylindrical member having a rear end in the form of a truncated cone and can therefore advantageously expand the gum surrounding an empty tooth socket to where an artificial tooth is to be mounted. The expanded gum allows subsequent formation of a tooth mold deeply reaching the root of the abutments of implanted tooth to produce a desired artificial tooth completely matching with neighboring teeth.
