Summary
High insertion torque damages dental implant threads, releasing titanium particles at the bone crest. This particle release may contribute to peri-implant diseases and marginal bone loss.
Area of Science:
- Biomaterials Science
- Dental Implantology
- Tissue Engineering
Background:
- Long-term dental implant success relies on supporting tissue preservation.
- Titanium particle release is implicated in peri-implant diseases.
- Surface changes from high insertion torque require investigation.
Purpose of the Study:
- To analyze surface changes in dental implants after high insertion torque placement.
- To investigate the release of titanium particles associated with surface damage.
Main Methods:
- Three implant groups with different surface topographies were inserted into cow rib bone blocks.
- A modified drilling protocol ensured high insertion torque.
- Surface roughness was measured using interferometry; particle analysis used SEM-BSD.
Main Results:
- High insertion torque caused surface damage, particularly at thread crests.
- Titanium particles were observed at the bone-implant interface, especially near the crestal bone.
- No significant differences in roughness changes were noted between implant groups.
Conclusions:
- High insertion torque leads to dental implant surface damage and titanium particle release.
- Particle release at the bone crest is a potential factor in marginal bone loss.
- Further research is needed on titanium particle release during implant insertion.

01:10Residual Stresses in Circular Shafts
140
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

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.

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.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...

01:18Stress Concentrations in Circular Shafts

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...

01:24Circular Shafts - Elastoplastic Materials

The study of solid circular shafts under stress shows that within the elastic limit, stress increases directly to the distance from the shaft's center. This relationship holds until the shaft reaches a critical point of stress, beyond which it begins to yield, marking the transition from elastic to plastic deformation. At this crucial juncture, the maximum torque the shaft can endure without permanent deformation is determined, signifying the limit of its elastic behavior.

When a mechanic tries to remove a hex nut with a wrench, it is easier if the force is applied at the farthest end of the wrench handle. The lever arm is the distance from the pivot point (the hex nut in this case) to the person’s hand. If this distance is large, the torque is higher. Only the component of the force perpendicular to the lever arm contributes to the torque. Therefore, pushing the wrench perpendicular to the lever arm is more advantageous. If multiple people apply force to...
