Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Osteoclasts in Bone Remodeling

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...

Background:

Bone remodeling around dental implants is crucial for long-term success, especially in patients with reduced bone width.
Understanding the biomechanical behavior of different implant materials and designs under load is essential for predicting bone response.

Purpose of the Study:

To predict time-dependent bone remodeling around tissue-level and bone-level dental implants in reduced bone width scenarios.
To compare the biomechanical performance of titanium and titanium-zirconium alloy bone-level implants against titanium tissue-level implants.

Main Methods:

Utilized three-dimensional finite element models based on Stanford theory.
Simulated a 100 N oblique load on peri-implant bone for one month.
Evaluated maximum/minimum principal stresses, strain energy density, and implant displacement (x- and y-axes).

Main Results:

Tissue-level implants exhibited higher maximum and minimum principal stresses compared to bone-level implants.
Both titanium and titanium-zirconium alloy bone-level implants showed comparable stress levels.
Total strain energy density in bone around titanium implants showed an initial decrease followed by recovery; titanium-zirconium implants had minor axial plane changes.
Tissue-level implants demonstrated greater strain energy density changes in cortical bone.

Conclusions:

Tissue-level dental implants are associated with higher peri-implant bone stresses than bone-level implants.
The time-dependent biomechanical outcome of titanium-zirconium alloy bone-level implants is comparable to titanium bone-level implants.
These findings contribute to understanding implant stability and bone remodeling in challenging clinical situations.
