The passivity of screw-retained restorations is challenging to achieve yet difficult to measure and quantify. The purpose of this article is to describe a digital technique to construct an implant verification jig that allows quantifying the degree of framework misfit. A gear cylinder is designed and connected to the digital scan over each implant component. The gears are connected to form a verification bar design. The milled bar is used with a plastic pointer mounted on the screwdriver to calculate the degree of framework misfit. Key message/ clinical relevance: This method is a helpful clinical tool that would help clinicians make better decisions regarding framework passivity. Furthermore, it can be helpful for a researcher who needs to quantify the degree of misfit instead of using subjective nonparametric techniques.

Purpose: To evaluate the global research landscape on dental prosthetic complications by identifying the most productive countries, institutions, authors, and journals. Additionally, it sought to highlight the most cited publications and commonly used keywords in the field.

Materials and methods: A comprehensive search was conducted in the Web of Science database on March 27, 2025, using the term 'dental prosthetic complications.' A total of 1665 English-language records (articles and reviews) published between January 2000 and December 2024 were analyzed. Bibliometric indicators-including publication year, citation count, country, institution, author, journal, and keywords-were evaluated using VOS viewer (v1.6.15) and Microsoft Excel.

Results: Research output increased substantially after 2010. Italy, the USA, and Germany ranked highest in publication volume, while Switzerland and Sweden showed the highest citation averages. The University of Bern was the most productive institution. Prolific authors included Marco Tallarico, Marco Esposito, Silvio Mario Meloni, and Niklaus P. Lang. Highly cited studies predominantly focused on complications in implant-supported restorations. Leading journals were The International Journal of Oral & Maxillofacial Implants, Clinical Oral Implants Research, Clinical Implant Dentistry and Related Research. Keyword analysis revealed that 'dental implants' and related terms remained central research themes.

Conclusions: The volume of research on dental prosthetic complications has grown considerably over the past two decades, particularly in relation to implant-based treatments. Since 2010, the growing number of publications and expanding international collaborations reflect rising scientific interest in this field. Recurrent complications continue to shape research priorities, highlighting the ongoing clinical significance of prosthetic complications.

Purpose: The present study aimed to compare sagittal condylar inclination (SCI) values obtained by three different methods-interocclusal wax recording, panoramic radiography, and electronic axiography (Cadiax-Compact 2).

Materials and methods: A total of 15 adults participated in this study. For the interocclusal recording, SCI was determined using protrusive interocclusal wax records, which were transferred to a semi-adjustable articulator. Panoramic radiographs were obtained and SCI values were measured by tracing the radiographic images. Extraoral tracings were recorded using a Cadiax-Compact 2. After a paraocclusal tray was fixed intraorally, each participant was instructed to perform three protrusive mandibular movements, and the average SCI values were calculated. The paired t-test was used to compare the SCI values of the right and left condyles. Pearson correlation analysis was performed to assess the relationship between the values obtained by the different methods, with a significance level set at p<0.05.

Results: No statistically significant difference was observed between right and left condyles for any of the three methods (p>0.05). The highest correlation was found between panoramic radiography and Cadiax-Compact 2, while moderate correlation was observed between interocclusal recordings and the other two methods. Interocclusal recordings yielded the lowest SCI values, while Cadiax-Compact 2 showed the highest.

Conclusion: Although panoramic radiography, and Cadiax-Compact 2 demonstrated strong correlation, interocclusal records showed moderate agreement and lower SCI values. However, considering the influence of functional movements, interocclusal recordings remain valuable for dentate patients. However, panoramic radiography can be a practical alternative in cases with limited neuromuscular control or a strong gag reflex.
