Alveoli and Alveolar Ducts01:26

Alveoli and Alveolar Ducts

2.4K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

Gross Anatomy of the Lungs01:17

Gross Anatomy of the Lungs

1.8K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

The Bronchial Tree01:23

The Bronchial Tree

2.5K
The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Anatomy of Respiratory System II: Lower Respiratory Tract01:31

Anatomy of Respiratory System II: Lower Respiratory Tract

956
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Anatomy of Respiratory System I: Upper Respiratory Tract

1.4K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Area of Science:

  • Dental surgery
  • Oral implantology
  • Bone regeneration

Background:

  • Atrophic edentulous sites often present inadequate bone width for dental implants.
  • Existing augmentation techniques include extracortical graft application and ridge splitting.
  • Limited vertical bone loss is common in these atrophic sites.

Purpose of the Study:

  • To describe surgical techniques for augmenting atrophic edentulous sites for dental implant placement.
  • To evaluate the suitability of ridge splitting and expansion for horizontal bone augmentation.

Main Methods:

  • Extracortical augmentation involves applying graft material to the cortical bone.
  • Ridge splitting and expansion separates facial and lingual cortices to create space for new bone formation.
  • Flapless surgical approaches are preferred to preserve periosteal blood supply.

Main Results:

  • Extracortical augmentation relies on progenitor cell migration for new bone formation.
  • Ridge splitting and expansion creates space for osteogenesis and potential implant placement.
  • Flapless ridge splitting maintains periosteal vascularity, promoting healing.

Conclusions:

  • Ridge splitting and expansion is a viable method for horizontal ridge augmentation in atrophic edentulous sites.
  • Flapless surgery in ridge splitting preserves blood supply, enhancing bone regeneration and healing.
  • Surgical augmentation techniques provide options for dental implant placement in deficient bone sites.
