Biomechanical evaluation of peak reverse torque (PRT) in a dynamic compression plate-screw construct used in a goat tibia segmental defect model

BMC Veterinary Research, 2019
Background Peak reverse torque (PRT) is a valid method to evaluate implants’ secondary stability in the healing bone. The secondary stability is achieved by the implant over time and it has been positively correlated with the implants’ osseointegration ...

Experimental and numerical analysis of the unreinforced and reinforced notched timber beam by a screw

Vietnam Journal of Science, Technology and Engineering, 2018
Timber is highly anisotropic. It behaves differently in diverse directions. Tension and compression perpendicular to the grain present a low strength with respect to the ones parallel to the grain.

Geometry of anchoring miniscrew in the lateral palate that support a tissue bone borne maxillary expander affects neighboring root damage

Scientific Reports, 2021
Anchoring miniscrews used for a tissue bone borne maxillary expander (C-expander) can fail if they contact tooth roots or perforate the maxillary sinus. Cone beam computed tomography images were reviewed retrospectively to evaluate the geometric factors ...

Comparative evaluation of insertion torque and mechanical stability for self-tapping and self-drilling orthodontic miniscrews – an in vitro study

Head & Face Medicine, 2017
Background The aim of the present study was to evaluate the relationship between insertion torque and stability of miniscrews in terms of resistance against dislocation, then comparing a self-tapping screw with a self-drilling one.

The Automated Threaded Fastening Based on On-line Identification

International Journal of Advanced Robotic Systems, 2004
The principle of the thread fastenings have been known and used for decades with the purpose of joining one component to another. Threaded fastenings are popular because they permit easy disassembly for maintenance, repair, relocation and recycling ...

ASSESSMENT OF IMPLANT STABILITY IN IMMEDIATELY LOADED MAXILLARY FIXED DETACHABLE RESTORATIONS USING OSSEODENSIFICATION (RANDOMIZED CLINICAL TRIAL) [PDF]

Alexandria Dental Journal
Background: Rehabilitation of single edentulous maxillary arches with screw-retained prostheses is considered an optimal treatment choice. However, atrophy in the maxilla may result in deficient bone volume for implants.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...

Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

Advanced Science, EarlyView.
ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+
