Article Synopsis
- - The study examines how dental implant diameter and taper design influence the mechanical engagement (anchorage) of implants when inserted into bone, focusing on stress distribution during insertion.
- - Two types of implants (parallel-walled and tapered) with different diameters were tested in rigid polyurethane foam using specific drilling methods to analyze their effects on insertion torque (IT) and stress distribution.
- - Results showed that for tapered implants, the diameter significantly impacted IT and stress distribution, indicating that taper design helps distribute stress away from the threads during insertion, unlike parallel-walled implants.
Article Synopsis
- The study focuses on maximum insertion torque (IT) for dental implants, a key factor in evaluating implant stability and clinical success.
- An analytical model was developed to separately assess contributions from the implant thread and taper, while also evaluating factors like bone density, drill technique, and surface finish.
- The model successfully distinguished between implant types and showed that higher bone density and specific drilling methods improved insertion torque, highlighting the importance of different design elements on implant effectiveness.
Article Synopsis
- Different methods to evaluate bone stiffness can vary a lot based on the background of the researchers and the complexity of bone itself.
- The study focused on quantifying errors in predicting long-bone bending stiffness (flexural rigidity) using a bi-material bone surrogate tested under specific conditions.
- Results showed that CAD-based finite element analysis (FEA) was the most accurate for determining bone stiffness, while mechanical testing was the least reliable, often underestimating flexural rigidity.
Effect of insertion factors on dental implant insertion torque/energy-experimental results.

Article Synopsis
- Anchorage of dental implants is measured using maximum insertion torque (MIT) and insertion energy (IE), which are important for ensuring positive clinical outcomes.
- * A study examined how factors like bone density, drill protocol, surface finish, and cutting flute affect MIT and IE using a controlled experiment with polyurethane foam blocks.
- * Results showed that MIT and IE respond differently to the insertion factors; the first insertion emphasized thread forming for IE, while subsequent insertions highlighted thread tightening for MIT, indicating that both metrics are essential for understanding dental implant anchorage.
The process monitoring of the top side and the evaluation of surface quality were applied in adjustable ring mode (ARM) laser welding of 316 stainless steel by using visual monitoring and confocal sensor technology. Experiments were conducted in different power arrangements of an ARM laser. In this study, the process status was evaluated based on the area of keyhole entrance and the width of the pool.
