Background
Wedge-shaped defects are V-shaped defects formed on the neck of a tooth after long-term friction of hard tissues of the tooth, and are named because the shape of the V-shaped defects is exactly like a wedge. It is believed that the formation of such defects is caused by the use of a bristle toothbrush and brushing the teeth in a transverse direction, and if the toothpaste used is a low-quality abrasive toothpaste, the bristles of the bristle toothbrush rub against the teeth for a long time, the enamel at the neck of the teeth is thin, the abrasion resistance is low, and a gap is formed after a long time. The wedge-shaped defects of light and moderate degree can cause tooth sour and cold, hot, sour and sweet allergic symptoms, and serious patients can cause pulpitis, periapical periodontitis, osteomyelitis and even dental fracture. Wedge-shaped defects of teeth are very common.
The patient with less tissue defect and no obvious symptom can be disregarded. If the patients with dentin hypersensitiveness or large defects occur, the patients should be repaired and filled with fillers such as resin and glass ions. However, in the prior art, when the filler is molded by operations such as extrusion, trowelling and the like in the process of repair treatment, the adopted repair instrument is a flat engraving tool, the material can be compacted by pressing the filler for many times, but the surface of the filler is subjected to seam welding at the same time, so that the filling repair efficiency and the repair quality are affected.
