Abstract Objectives The stability of the abutment screw is pivotal for successful implant‐supported restorations, yet loosening remains a common complication, leading to compromised function and potential implant failure. This study aims evaluate effect different implant‐abutment types heights on in cases with increased crown height space (CHS). Materials Methods In this vitro study, total 64 abutments eight distinct groups based their type were evaluated. These included stock, cast, milled 4 mm (groups S4, C4, M4), 7 S7, C7, M7), 10 C10 M10). Removal torque loss (RTL) was assessed both before after subjecting dynamic cyclic loading. Additionally, differences between initial RTL following loading analyzed each group ( p < .05). Results demonstrated highest RTL, whereas S4 exhibited lowest percentage Furthermore, established significant variations percentages discrepancies postcyclic across found significantly influence Conclusion affected loosening, an CHS 12 mm, using stock postheight can be effective minimizing loosening.

Peri-implant diseases, such as peri-implantitis, affect up to 47% of dental implant recipients, primarily due biofilm formation. Current decontamination methods vary in efficacy, prompting interest polymeric nanoparticles (NPs) for their antimicrobial and protein-specific cleaning properties. This study evaluated the efficacy decontaminating titanium implants by removing proteinaceous pellicle layers resisting recontamination. Titanium discs were treated with saline water, PrefGel ® , hydrogen peroxide (H 2 O ), GUM Paroex or NPs, analysed using SEM, EDX, XPS, contact angle measurements assess changes surface composition, morphology, hydrophilicity. Polymeric NPs significantly reduced nitrogen levels compared PrefGel® (mean reduction: 2.6%, p < 0.05), indicating effective protein removal. However, carbon reduction was similar that other agents. SEM images revealed disaggregated larger aggregates but did not fully decontaminate surface. Contact analysis showed hydrophilicity consistent treatments. Hydrogen performed best overall, achieving lowest post-recontamination 13%, 0.01). While exhibited unique potential, overall performance comparable traditional Residual contaminants, including oxygen, persisted on all surfaces, enhanced strategies needed. These findings highlight potential an innovative approach decontamination, particularly control. broader applications remains like conventional methods. research contributes developing targeted protocols manage peri-implant diseases improve long-term outcomes.
