Clinical Evaluation of 762 Single-Tooth, Locking-Taper Implants: A Prospective Study with 1- to 12-Years of Follow-Up

Nowadays, dental implants represent the state-of-the-art treatment for replacing single missing teeth, as demonstrated by several long-term follow-up studies, with satisfactory high survival rates However, biological and prosthetic complications still affect single crowns (SCs) supported by dental implants Biological complications include complications that affects only soft tissues (such as pain and swelling after surgery, or peri-implant mucositis) and complications that affect both soft and hard tissues (such as peri-implantitis) Prosthetic complications include mechanical complications (i.e. complications that affect prefabricated implant components, such as screw or abutment loosening, screw or abutment fracture) and technical complications (i.e. complications that affect superstructures, such as fracture/chipping of veneering materials and the need for recementation)
