This invention provides a black triangular restorative patch, comprising an elastically molded patch body. Two sides of the elastically molded patch body are bent to form a covering body. The covering body has injection holes suitable for injecting fluid resin. A traction and pressing wing extends from the outer side of the covering body away from the patch body, with the outer side of the traction and pressing wing extending outwards towards the covering body and the inner side extending inwards towards the covering body. This invention not only allows the patch to fit more tightly against the tooth but also minimizes the gap between the inner side of the traction and pressing wing and the edge of the affected tooth. This ensures a tight seal with the edge of the affected tooth after resin injection, preventing the resin from forming a protrusion and creating a smooth transition. This reduces the workload of subsequent polishing. Furthermore, the resin injection holes on the covering body avoid the problem of resin being introduced through the labial side of the patch, as is common in existing methods. Polishing only requires removing the resin corresponding to the injection hole, improving restorative efficiency.
