Resonance frequency analysis of miniscrew implant stability

Journal of Oral Science, 2018
This study used resonance frequency (RF) analysis to assess miniscrew implant (MSI) stability during wound healing in a sample of 68 patients (41 women, 27 men; mean age, 27.7 years). The 104 MSIs included 66 placements in the buccal shelf (BS; 2.0 × 12 mm) and 38 placements in interradicular (IR; 1.5 × 8 mm) sites. Thirteen (12.5%) of the MSIs failed.

Detecting Intralabyrinthine Pressure Increase by Postural Manipulation with Wideband Tympanometry and Distortion Product Otoacoustic Emissions

Turkish Archives of Otorhinolaryngology, 2020
Objective: Intracranial pressure increase is known to affect inner ear pressure through the cochlear and vestibular aqueducts. This finding forms a good model for inner ear pressure studies.

Reliability and Agreement of Three Devices for Measuring Implant Stability Quotient in the Animal Ex Vivo Model

Applied Sciences, 2021
Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The implant stability quotient (ISQ) is the measure obtained by different RFA devices; however, inter- and intra-rater reliability and agreement of these ...

Evaluating the Effect of Design and Length of Implants on Primary Stability Using Resonance Frequency Analysis: An In Vitro Study

Selcuk Dental Journal, 2020
Background:Primary stability (PS) is dependent on the length and diameter of the implant, micro-morphology of the implant surface, implant design, surgical procedure, bone quantity and quality.The aim of this study was to compare short and standart ...

Frequency analysis and resonant operation for efficient capacitive deionization

Water Research, 2018
Capacitive deionization (CDI) performance metrics can vary widely with operating methods. We here develop a theory around and experimentally demonstrate a new operation for CDI that uses sinusoidal forcing voltage (or sinusoidal current). We use a dynamic system modeling approach, and quantify the frequency response (amplitude and phase) of CDI ...

Axis of success: Primary and secondary stability of implant

Indian Journal of Dental Sciences, 2021
Primary and secondary stability mainly proceed along with mechanical phenomenon of implant engagement within the surrounding bone. Primary stability is an important element in attainment of secondary implant stability.

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Multi-Scale Characterization of Conventional and Immediate Dental Implant Systems

Journal of Functional Biomaterials
We hypothesized that the different post-implantation healing stages between the conventional and immediate implantations produce different amounts and tissue composition of the peri-implant bone.
