A stable implant

Abstract

The utility model provides a stable implant, including a column, a support sheet and a fastener. The column is provided with a first inner hexagonal groove and an external thread that can be screwed into the alveolar bone. The support sheet is in the shape of an arc sheet. One end of the support sheet is provided with a mounting hole for the column to pass through. The fastener can cooperate with the external thread to tighten and fix the support sheet on the column. During operation, the mounting column is first screwed into the alveolar bone, and then the support sheet is fixed to the column with the fastener. The arc-shaped support sheet covers one side surface of the alveolar bone, and the support sheet can be wrapped after the soft tissue near the tooth bone is healed. The support sheet is embedded in the soft tissue to form a whole with the soft tissue, thereby supporting and stabilizing the column, thereby improving the stability of the entire implant.

[0024] Reference Figures 1 to 6 The utility model provides a stable implant, including a column 1, a support sheet 2 and a fastener 3. The column 1 is provided with an external thread 11 that can be screwed into the alveolar bone, the upper end of the column 1 is provided with a first internal hexagonal groove 12, and the bottom of the first internal hexagonal groove 12 is provided with an internal thread groove 13. The support sheet 2 is in the shape of an arc-shaped sheet that bends downward, and one end of the support sheet 2 is provided with a mounting hole 21 for the column 1 to pass through. The fastener 3 can be connected with the external thread 11 in a threaded matching manner to tighten and fix the support sheet 2 on the column 1, and the support sheet 2 can cover the surface of one side of the alveolar bone to support the column 1.

[0025] During operation, after a hole is drilled in the alveolar bone, a tool is used to cooperate with the first hexagon socket to screw the mounting column 1 into the hole drilled in the alveolar bone, and then the support plate 2 is put on the column 1. The support plate 2 is fixed to the column 1 by the fastener 3 in cooperation with the external thread 11 of the support column. The arc-shaped support plate 2 covers one side surface of the alveolar bone, and the support plate 2 can be wrapped after the soft tissue near the tooth bone heals. The support plate 2 is embedded in the soft tissue to form a whole with the soft tissue, which supports and stabilizes the column 1, thereby improving the stability of the entire implant.
