Implantation of teeth: contraindications

Implantation of teeth is a progressive modern method of complete restoration of lost teeth. This procedure is better than a denture or a non-removable bridge denture, for attachment of which adjacent teeth are used. According to statistics, such an operation ends successfully in 95% on the lower jaw, and in 90% - for the upper jaw. Dental implants have many advantages over dentures: they do not interfere with eating or talking, do not bother with extraneous sounds, are not visible to strangers, are durable( if properly taken care of implants, they will last for life).

Like any medical procedure, it has dental implantation and contraindications. In addition, modern dentistry applies this method of treatment only when orthopedic methods have not produced results, since implantation is a serious surgical intervention.
