Abstract Introduction. In the context of modern dental medicine, fixed dental prosthetics have become an increasingly common option for patients with affected teeth. However, there is a growing need to understand the impact of these restorations on periodontal health. In order to address this situation and restore patients’ functionality and smile aesthetics, fixed dental prosthetics have become a frequently used solution. They represent a complex and sophisticated technique for replacing missing or compromised teeth. Nevertheless, a relevant question arises: How do fixed dental prosthetics affect the periodontal health of patients? This question forms the central axis of the research presented in this work. Materials and Methods. For the study, a sample of 10 patients aged between 30-60 years with fixed dental prosthetics installed within the last 5 years was selected. We used fixed dental crowns and bridges made from various materials such as metal-ceramic or zirconia-based ceramic. The fixation was achieved through cementation. The research methods included detailed clinical examinations, including measuring the depth of periodontal pockets using periodontal probes, as well as intraoral radiographs for assessing bone level. Results. This study indicates that fixed dental prosthetics can have a significant impact on periodontal health. Despite the functional and aesthetic benefits they offer, these prosthetics can influence oral hygiene and contribute to an increased risk of gingival inflammation or more severe conditions such as periodontitis. Conclusion. This research suggests that fixed dental prosthetics influence periodontal health. While they can improve patients’ quality of life by restoring dental functionality and aesthetics, prosthetics can also contribute to the accumulation of bacterial plaque and gingival inflammation. This study underscores the necessity of patient education regarding rigorous oral hygiene and the need for regular monitoring to detect and manage potential complications in their early stages.
