Periodontal maintenance therapy (PMT) is a set of procedures performed at regular intervals to maintain oral health after active periodontal therapy or until teeth are replaced by implants. The aim of this study was to interpret the effectiveness and key components of PMT through the analysis of recent and relevant studies. A literature review was conducted using electronic scientific databases such as PubMed, Elsevier, and Wiley, employing MeSH terms and inclusion criteria that focused on studies published within the last five years. The results revealed that PMT plays a crucial role in the long-term preservation of teeth and periodontal health, significantly reducing clinical parameters such as bleeding on probing and periodontal pocket depth, particularly in patients with chronic periodontitis. Additionally, factors such as biofilm control, visit frequency, and adherence to maintenance programs were found to significantly influence clinical outcomes. It is concluded that long-term periodontal stability is achievable when patients maintain proper oral hygiene, avoid habits such as smoking, and regularly attend personalized maintenance appointments, with recommended intervals ranging from 3 to 6 months depending on observed biofilm control. This comprehensive and personalized approach is essential to ensuring the success of PMT and preventing the progression of periodontal disease
