Bone Remodeling01:40

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.
Fractures: Bone Repair01:27

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Osteoclasts in Bone Remodeling01:31

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...
Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...
Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Summary
This summary is machine-generated.

This study in beagle dogs shows that small-diameter implants in fresh extraction sites cause bone remodeling. Proper implant positioning and narrow diameter can reduce vertical bone resorption at the buccal aspect.

Area of Science:

  • Dental Implantology
  • Oral Surgery
  • Bone Physiology

Background:

  • Immediate implant placement in fresh extraction sockets is a common dental procedure.
  • Understanding bone remodeling around small-diameter implants is crucial for long-term success.
  • Physiologic bone changes following immediate implant placement require detailed investigation.

Purpose of the Study:

  • To evaluate the physiologic bone remodeling around small-diameter (3.25 mm) implants.
  • To assess bone changes in fresh extraction sites after immediate implant placement in beagle dogs.
  • To determine the effect of implant positioning and diameter on vertical bone resorption.

Main Methods:

  • Five beagle dogs received small-diameter implants in fresh premolar extraction sockets.
  • Buccolingual bone crest width and implant shoulder-to-bone crest distance were measured.
  • Measurements were taken immediately after extraction and at 2, 4, and 12 weeks post-implantation.

Main Results:

  • A mean vertical buccal bone resorption of 0.5 mm was observed.
  • Bone width decreased from 4.5 mm at extraction to 3.5 mm at 12 weeks.
  • Lingual bone crest showed minimal changes, while buccal bone showed some resorption over time.

Conclusions:

  • Vertical bone remodeling occurs around small-diameter implants in fresh extraction sites.
  • Implant positioning favoring the lingual wall and narrow implant diameter may minimize buccal bone resorption.
  • These factors are key in reducing vertical bone loss at the buccal aspect of implants.
