Abstract
Aim: The purpose of this study is to investigate the interchangeability of newly acquired, short-term used, and long-term used semi-adjustable articulators.
Materials and methods: Metal analogs of partially dentate maxillary and mandibular arches were mounted on twelve semi-adjustable Stratos 300 articulators, divided into three groups based on usage over time: New, short-term used (<2 years), long-term used (>2 years) articulators. Each articulator was calibrated according to manufacturer guidelines, ensuring consistency. Occlusal contact forces were recorded using a T-scan III device with a pressure-mapping sensor. Maximum intercuspation (MIP) contact magnitudes were recorded by two calibrated examiners at 10-second intervals, ensuring reliable data collection across all conditions.
Results: In MIP, tooth #9 consistently exhibited the highest contact percentages across all articulator conditions, with percentages of 22.2% in the new articulator, 21.8% in the short-term used articulators, and 21.5% in long-term used articulators, indicating stable contact force distribution. Tooth #12 consistently showed the lowest MIP contact percentages, suggesting minimal occlusal force in this region due to its absence. Contact forces, measured at 10-second intervals, showed no significant differences among the different articulator conditions in MIP (p > 0.01).
Conclusion: Within the limitations of this in vitro study, the calibrated Stratos 300 semi-adjustable articulator maintained superior accuracy over time.
Clinical significance: The study confirms that the calibrated Stratos 300 semi-adjustable articulators provide consistent and accurate occlusal measurements over time, regardless of their usage over time.

期刊介绍：
The Journal of Contemporary Dental Practice (JCDP), is a peer-reviewed, open access MEDLINE indexed journal. The journal’s full text is available online at http://www.thejcdp.com. The journal allows free access (open access) to its contents. Articles with clinical relevance will be given preference for publication. The Journal publishes original research papers, review articles, rare and novel case reports, and clinical techniques. Manuscripts are invited from all specialties of dentistry i.e., conservative dentistry and endodontics, dentofacial orthopedics and orthodontics, oral medicine and radiology, oral pathology, oral surgery, orodental diseases, pediatric dentistry, implantology, periodontics, clinical aspects of public health dentistry, and prosthodontics.
