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.

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 ...

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 ...
Bush regeneration. Bush regeneration, a form of natural area restoration, is the term used in Australia for the ecological restoration of remnant vegetation areas, such as through the minimisation of negative disturbances, both exogenous such as exotic weeds and endogenous such as erosion. It may also attempt to recreate conditions of pre ...
Forest restoration is defined as "actions to re-instate ecological processes, which accelerate recovery of forest structure, ecological functioning and biodiversity levels towards those typical of climax forest ", [1] i.e. the end-stage of natural forest succession. Climax forests are relatively stable ecosystems that have developed the maximum ...
v. t. e. Ridge regression is a method of estimating the coefficients of multiple- regression models in scenarios where the independent variables are highly correlated. [1] It has been used in many fields including econometrics, chemistry, and engineering. [2] Also known as Tikhonov regularization, named for Andrey Tikhonov, it is a method of ...
