In conclusion, our analyses revealed a cumulative survival rate of 89.8% of TPS-surface implants with at least 25 years of functioning. The survival rate of maxillary positioned implants was significantly lower than that of mandibulary positioned implants. The patient gender, implant location, and width of keratinized mucosa affected the rate of peri-implantitis, resulting in late failure. Implant-supported overdentures were frequently repaired compared to the fixed prostheses due to the wear or fracture of artificial teeth, attachment fracture, and relines. Tooth implant-supported prostheses were not beneficial for long term owing to the troubles of abutment tooth.
