Purpose: The aim of this study is to assess the impact of insertion torque and implant neck design on peri-implant bone levels and gain insights into dynamic crestal tissue alterations by radiological, clinical, and biochemical examinations.
Material And Methods: In this prospective trial, a total of 84 implants (four implants in each patient) in the interforaminal region of 21 edentulous mandibles were randomly alternated according to a split-mouth design. Implant placement was performed using different insertion torques (≤20 Ncm vs >50 Ncm). In each group, one machined and one anodized implant neck design (1.5 mm length) was used in the same jaw side. Evaluation of peri-implant tissues involved radiological, clinical examination and immunoassays for interleukin-1β.
Results: No significant influence of insertion torque or implant neck design on peri-implant bone level was found. Protein levels of interleukin-1β in the peri-implant crevicular fluid revealed no difference between both insertion torque groups and different neck designs.
Conclusion: Interactive effects of insertion torque and neck surface modification may exist; however, no clinically significant differences in marginal bone resorption after 1 year could be observed in the edentulous anterior mandible.

Objectives: This study aimed to evaluate the osseointegration properties of titanium bone implants coated with carob-mediated calcium hydroxide nanoparticles biomechanically, radiographically, and histologically on rabbit tibias.
Material And Methods: Forty coated and forty uncoated titanium alloy bone implants were inserted into 20 New Zealand rabbits; each tibia received 2 implants. The rabbits were sacrificed after 4 or 8 weeks, and samples were retrieved for biomechanical evaluation through removal torque test to assess the bond between implant and bone, radiographic evaluation through microcomputed tomography analysis to compare the bone-to-implant contact percentage and bone volume of the peri-implant area, scanning electron microscopic and histologic evaluation through hematoxylin and eosin stain.

Background: Lumbar degenerative diseases are an important factor in disability worldwide, and they are also common among the elderly population. Stand-Alone Oblique Lumbar Interbody Fusion (Stand-Alone OLIF) is a novel surgical approach for treating lumbar degenerative diseases. However, long-term follow-up after surgery has revealed the risk of endplate collapse associated with Stand-Alone OLIF procedures.

Article Synopsis
- The study focuses on infrazygomatic miniscrew implants (IZC-MSI) as temporary anchorage devices in orthodontics, highlighting their importance in supporting maxillary tooth movement.
- The systematic review aimed to evaluate the success rate and stability factors of IZC-MSI through a comprehensive electronic search of multiple databases.
- Results from 14 studies indicated a 92% overall success rate for these implants, with variations based on sample size and significant heterogeneity in factors influencing their stability.
Enhancing Field-Like Efficiency Via Interface Engineering with Sub-Atomic Layer Ta Insertion.

School of Electronic Science and Engineering, Nanjing University, Nanjing, 210023, China.
The prevailing research emphasis has been on reducing the critical switching current density (J) by enhancing the damping-like efficiency (β). However, recent studies have shown that the field-like efficiency (β) can also play a major role in reducing J. In this study, the central inversion asymmetry of Pt-Co is significantly enhanced through interface engineering at the sub-atomic layer of Ta, thereby inducing substantial alterations in the β associated with the interface.
