Outcomes of Dental Implants in Routine Clinical Practice: A Retrospective Multicenter Study

Area of Science:

• Dentistry
• Oral Implantology
• Periodontology

Background:

• Dental implants are a common prosthetic solution for missing teeth.
• Assessing clinical and radiographic outcomes in daily practice is crucial for treatment optimization.
• Understanding factors influencing marginal bone loss (MBL) and implant survival is essential.

Purpose of the Study:

• To evaluate clinical and radiographic outcomes of dental implants placed in routine dental practice.
• To analyze the impact of various factors on marginal bone loss (MBL) and implant survival rates.
• To determine the prevalence of peri-implant mucositis in a cohort of patients receiving dental implants.

Main Methods:

• Retrospective multicentric case series of 339 patients receiving 651 implants.
• Data collected between January 2019 and January 2023 across five private clinics.
• Analysis of variables including soft tissue status, implant placement (crestal/subcrestal, immediate/delayed), bone grafting, and prosthesis type (screwed/cemented).

Main Results:

• Implant survival rate was 99.9%, with one failure reported.
• Immediate implant placement resulted in significantly greater MBL than delayed placement (p=0.0002).
• Subcrestal placement and cemented prostheses showed significantly less MBL (p < 0.0001).
• Peri-implant mucositis prevalence was 3.6% on an implant basis.
• No intra-operative complications or adverse events were reported during follow-up.

Conclusions:

• High clinical and radiographic success rates for dental implants are achievable in routine practice.
• Adherence to established guidelines, personalized treatment planning, and manufacturer recommendations are key.
• Understanding influencing factors like placement strategy and prosthesis design can optimize MBL outcomes.
