Dental implants are crucial in modern dentistry for replacing missing teeth, and accurate identification of implant brands is essential for effective treatment and long-term patient care. Traditional methods of implant identification rely on manual comparison with reference libraries and visual assessment, which are often time-consuming and prone to errors due to the increasing variety of implant brands. AI offers a promising alternative by automating the detection process, thereby improving accuracy and reducing the reliance on human expertise. The study highlights the importance of preprocessing OPG images through techniques such as contrast enhancement and noise reduction to improve the visibility of critical implant features. It also discusses the role of image segmentation in isolating implants from surrounding anatomical structures, which is crucial for accurate analysis. Feature extraction, another key step, involves identifying and isolating unique implant characteristics that distinguish different brands. The integration of AI in clinical practice offers significant advantages, including faster and more reliable implant identification, which can enhance treatment planning and patient outcomes. However, the study also acknowledges the challenges associated with AI, such as the need for large, well-annotated datasets and the ethical concerns related to data privacy and the interpretability of AI models.

These biofilm-mediated inflammatory conditions represent an infectious disease process that can progress to peri-implant disease and functional illness if not managed appropriately. Early identification and timely intervention, guided by principles of preventive medicine, during the post-restorative maintenance phase are essential for long-term implant success. This cross-sectional study aimed to evaluate the prevalence of peri-implant mucositis and peri-implantitis one year after prosthetic loading in patients with previously treated generalized chronic periodontitis, maintained on regular supportive periodontal therapy (SPT). The study included patients aged 30-60 years with a history of generalized chronic periodontitis who had undergone full-mouth periodontal flap surgery and were compliant with SPT for at least one-year post-implant prosthetic loading. Peri-implant conditions were diagnosed according to the 2017 AAP/EFP classification criteria. Data from 403 patients and 679 implants were analyzed using SPSS 23.0 to determine prevalence rates at both patient and implant levels. Among 403 patients (44.9% female, 55.1% male), 55.6% exhibited peri-implant health, 28.5% had peri-implant mucositis, and 15.9% showed peri-implantitis. At the implant level, 73.8% of the 679 implants were healthy, while 15.2% had mucositis and 11.0% had peri-implantitis. In a high-risk population with a history of generalized chronic periodontitis and adherence to supportive periodontal therapy, peri-implant mucositis and peri-implantitis were prevalent one-year post-loading.
