Bone Markings

Bone Markings

Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Bone Formation by Intramembranous Ossification

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 ...

Venous Thrombosis I: Introduction

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

The Bone Matrix

The Bone Matrix

Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in...

Veins

Veins

Veins are an integral part of our circulatory system, serving as the blood vessels that transport blood from all body regions to the heart. They are a network of hollow tubes that carry blood low in oxygen from the body's cells back to the heart for reoxygenation. Veins are crucial for maintaining the body's overall fluid balance and the continuous circulation of blood.
Structure of Veins:
The structure of veins is specifically designed to assist in the low-pressure transportation of...

Area of Science:

Oral surgery
Regenerative medicine
Dental implantology

Background:

Insufficient bone height in the posterior maxilla commonly hinders dental implant placement.
Sinus grafting is a predictable method to augment bone height in this region.
This study explores a novel sinus elevation technique using venous coagulum.

Observation:

Five sinus elevations with simultaneous dental implant placement were performed using venous coagulum as the sole biomaterial.
Bone formation was assessed clinically, radiographically, and histologically after 8-9 months.
Micro-CT and histomorphometry were used to evaluate bone quality and quantity.

Findings:

Significant bone height increase was observed adjacent to implants.
Micro-CT revealed well-structured trabecular bone formation.
Histomorphometry showed 38% to 74% vital bone in biopsies.

Implications:

Venous coagulum can eliminate the need for traditional bone-grafting materials in sinus lifts.
This approach addresses ethical, religious, and safety concerns associated with allografts or xenografts.
Utilizing autologous blood simplifies the sinus lift procedure, potentially increasing patient access to dental implants.
