Based on positive clinical results of regeneration in periodontology research in the 1980s, research began to focus on the potential for re-building alveolar bone defects using guided bone regeneration. The theory of Guided tissue regeneration has been challenged in dentistry. The GBR principle was first examined by Dahlin et al. in 1988 on rats.
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [ 1 ] [ 2 ] After tooth extraction, the jaw bone has a natural tendency to become narrow , and lose its original shape because the bone quickly resorbs , resulting in 30–60% loss in bone volume in the first six months.

Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, or partial regeneration, which involves closing up the injury site with some gradation of scar tissue. Some tissues such as skin, the vas deferens, and large organs including the liver can regrow quite readily, while ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.

A colony of human embryonic stem cells. Regenerative medicine deals with the "process of replacing, engineering or regenerating human or animal cells, tissues or organs to restore or establish normal function". [ 1 ] This field holds the promise of engineering damaged tissues and organs by stimulating the body's own repair mechanisms to ...
That's why this cardigan is a great choice; it's warm enough to wear throughout fall and winter, but lightweight enough to work as an extra layer on chillier end-of-summer nights. Right now, it's ...
