What is alveolar process resorption?
Alveolar bone resorption is frequently observed after tooth extraction. Atrophy of the alveolar ridge may cause esthetic and surgical problems in prosthetic dentistry. Augmentative measures may thus be required to guarantee optimal prosthetic replacement of the lost tissues.
What is bone resorption medical term?
Bone resorption is the destruction of bone tissues that promotes bone loss, that is, a decrease in bone mass and bone density.
What are the two types of bone resorption?
The bone resorption lacunae were divided into two types (I and II) according to differences in morphological features of their walls; the wall of type I lacunae was covered with loose collagen fibrils, while that of type II lacunae was smooth with almost no fibrillar structures.
What is alveolar bone preservation?
Alveolar ridge preservation (ARP) is a method of decreasing bone resorption following tooth extraction and facilitating prosthetically-driven implant placement. An understanding of the physiological responses occurring after extraction and the effects of ARP are important in order to implement clinical procedures.
Is resorption and reabsorption the same thing?
The short answer is that reabsorption refers to the process of absorbing something again, while resorption refers to the process of losing substance. In this article, we’ll help you remember the difference between resorption and reabsorption and show you examples of each word in context.
What is alveolar remodeling?
Alveolar bone remodeling is expected to follow orthodontic tooth movement in a one-to-one relationship. However, in many cases, the outcomes are different. Alveolar bone might still remain thick causing lip protrusion and other aesthetic problems after treatment. Additional corrective procedures such as alveoloplasty.
What is Transseptal ligament?
Transseptal fibers (H) extend over the alveolar bone crest and are embedded in the cementum of adjacent teeth where they form an interdental ligament. These fibers work to keep the teeth aligned. These fibers may be considered as belonging to the gingival tissue as they do not have an osseous attachment.
What is bone resorption and bone deposition?
In bone resorption, the collagen and other proteins in bone tissue are digested by proteases, and bone mineral is dissolved to release calcium and phosphate to the extracellular fluid. Bone deposition is the process whereby new bone is formed.
What is the difference between filtration reabsorption and secretion?
The filtrate absorbed in the glomerulus flows through the renal tubule, where nutrients and water are reabsorbed into capillaries. At the same time, waste ions and hydrogen ions pass from the capillaries into the renal tubule. This process is called secretion.
Is dehiscence the same as recession?
Whenever bone loss is limited to a single tooth surface, usually the buccal one, bone defect is best known as dehiscence (Figs 5, 6 ). Over time, normal or inflamed gingival soft tissues tend to keep up with cervical bone levels; therefore, gingival recession is established.
What is dehiscence bone?
Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]
What best describes bone remodeling?
Bone remodeling (or bone metabolism) is a lifelong process where mature bone tissue is removed from the skeleton (a process called bone resorption) and new bone tissue is formed (a process called ossification or new bone formation).
What is meant by bone remodeling?
Bone remodeling involves the removal of mineralized bone by osteoclasts followed by the formation of bone matrix through the osteoblasts that subsequently become mineralized.
What is bone resorption and osteoporosis?
In adults, the daily removal of small amounts of bone mineral, a process called resorption, is balanced by an equal deposition of new mineral in order to maintain bone strength. When this balance tips toward excessive resorption, bones weaken and over time can become brittle and prone to fracture (osteoporosis).
What causes alveolar bone resorption?
BONE RESORPTION Alveolar bone resorption may be of systemic origin (disease, faulty metabo- lism, or dietary deficiencies) or the result of trauma. The biologic factor may be disclosed through a complete and careful dental examination.
What are the mechanisms of alveolar bone remodeling?
[Mechanisms of alveolar bone remodeling] The maintenance of bone is achieved by a fine balance between bone formation and bone resorption. The differentiation and activation of osteoclasts are tightly regulated by osteoblasts. Osteoblasts express at least two cytokines essential for osteoclast differentiation; they are receptor activator o …
What is alveolar bone?
Alveolar bone is the specialized part of maxillary and mandibular bone that supports the teeth. It forms with the eruption of teeth and gradually disappears after the tooth is lost.
Are there any precautions to be taken to prevent alveolar resorption?
Although alveolar resorption is not under the control of the dentist, certain precautionary measures may be taken to minimize its extent. ORAL EXAMINATION All too frequently the only examination made of the edentulous patient is a cursory inspection of the ridges.
