The Correlation Between Immediate Implant Insertion Torque and Implant Stability Quotient
The International Journal of Periodontics & Restorative Dentistry
|October 15, 2016
Summary
This study found no significant correlation between implant insertion torque value (ITV) and implant stability quotient (ISQ) in nonmolar sites. These findings suggest that excessively high ITV and ISQ may not be necessary for immediate implant temporization or osseointegration.
Area of Science:
- Dental Implantology
- Biomaterials Science
Background:
- Primary implant stability is crucial for successful osseointegration.
- Implant insertion torque value (ITV) and implant stability quotient (ISQ) are commonly used metrics to assess primary stability.
Purpose of the Study:
- To investigate the correlation between immediate implant insertion torque value (ITV) and implant stability quotient (ISQ) in nonmolar sites.
- To evaluate the clinical implications of this correlation for immediate temporization and osseointegration.
Main Methods:
- Retrospective study of 59 implants in 52 patients placed into extraction sockets.
- ITV recorded during surgery; ISQ recorded at surgery and follow-up.
- Correlation analysis performed between ITV and ISQ measurements.
Main Results:
- A nonsignificant correlation coefficient (r=0.06) was found between ITV and ISQ.
- No linear correlation was observed between these two primary stability measurements in the studied population.
Conclusions:
- The findings question the necessity of excessively high ITV and ISQ values as prerequisites for immediate temporization.
- The study suggests that successful osseointegration may not solely depend on achieving maximal primary stability as measured by ITV and ISQ.

1.0K
The shaft PQ is subjected to a twisting force when equal and opposite torques are applied on either side. A section that cuts perpendicular to the shaft's axis at any arbitrary point R is examined to understand this. When the free-body diagram of the QR segment is analyzed, it reveals the shearing forces exerted by the PR portion onto the QR segment as the shaft experiences twisting.
Applying equilibrium conditions to the QR segment establishes that the internal shearing forces within the...

01:10Residual Stresses in Circular Shafts
581
In materials that exhibit elastic and plastic behavior, known as elastoplastic materials, residual stresses can accumulate when these materials experience plastic deformation. This deformation arises from either high levels of shearing stress or significant strains. Residual stresses are internal stresses that persist within a material after removing the external force causing deformation. This phenomenon is demonstrated when observing the behavior of a shaft under torque; notably, the...

01:21Screw: Problem Solving
758
In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.

Consider the elastic torsion formula, which applies to a circular shaft with a consistent cross-section. This formula assumes that the shaft's ends are loaded with rigid plates firmly attached. However, in many cases, torques are applied to the shaft through mechanisms like flange couplings or gears, which are connected by keys inserted into keyways. This application method modifies the stress distribution near the point of torque application, causing it to deviate from the distributions...

1.7K
Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.
