The explanatory dental video begins by showing the fracture of a tooth, the upper right incisor, and the subsequent extraction of the remaining root. The solution using a single dental implant and an implant-supported crown is shown below. The two adjacent teeth (21 and 12) are prepared and a 3-crown bridge is placed. Over time, the lack of function in the area of tooth 11 leads to a loss of bone volume and a consequent collapse of the gingiva. In 21, gingival recession and caries appear under the prosthetic crown. This results in deep decay, crown fracture and tooth extraction.
In order to be able to continue to offer the option of rehabilitation of the area by means of a bridge over natural teeth, it is necessary to grind tooth number 22 in order to make a 4-crown bridge supported by two natural roots. This eventually leads to bone and gum loss in the pontic area. The video ends with a final comparative image of the two treatments.
