Summary
Immediate replantation and stabilization of avulsed teeth promote healing. This case report shows successful bone regeneration after intentional extrusion and splinting of an intruded incisor following trauma.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Regenerative Medicine
Background:
- Tooth avulsion interrupts pulp blood supply, risking periodontal ligament cell injury.
- Timely replantation and a conducive environment are crucial for complete tooth healing.
- Traumatic dental injuries, like those from road traffic accidents, necessitate prompt and effective management.
Observation:
- A case report details an intruded and mobile upper left central incisor in a 22-year-old patient post-road traffic accident.
- Intentional extrusion of the traumatized tooth was performed.
- Flexible acrylic wire splinting was utilized for stabilization.
Findings:
- Initially, there was a lack of periapical bone support.
- After a nine-month follow-up, significant improvement in bone healing was observed.
- The treatment successfully stabilized the injured tooth and promoted bone regeneration.
Implications:
- This case highlights the potential for successful outcomes in managing severe dental trauma.
- Intentional extrusion and splinting can be effective strategies for intruded teeth.
- The findings support the importance of immediate management and follow-up for traumatic dental injuries to achieve bone regeneration.

01:09Spongy Bone
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

01:29Bone 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...

01:40Bone 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.
01:55Bone Structure
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
01:27Fractures: 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...
