A comparison of peri-implant health across different types of implant-supported prostheses and anatomical locations: a cross-sectional observational study.

This study investigates the relationship between peri-implant soft tissue health and different types of implant-supported prostheses and anatomical implant locations. Conducted as a cross-sectional observational study with 134 adult patients and 456 implants, it found that full-arch implant-supported fixed dental prostheses exhibited higher rates of bleeding on probing and suppuration compared to single tooth implants. Implants located in the mandible showed more bleeding than those in the maxilla, and anterior implants had more bleeding than posterior ones. Additionally, implants with probing depths of 6 mm or greater were significantly more likely to present suppuration, indicating increased risk for peri-implant complications. These findings highlight the importance of monitoring implant type, location, and probing depth to guide supportive implant therapy and early intervention.
