Stem Cell Dental Implants Grow New Teeth In 2 Months!
Tooth loss is a problem that many people experience at a certain point. Currently, dental implants and dentures are the only solution, but none of them seems to offer satisfying results. Dental implants are not able to “remodel” as the jaw bone changes with time, while dentures are quite uncomfortable and come with their own set of faults.
This is the reason why people are so hopeful when it comes to stem cell research. While this medical method is surrounded with some controversy, it`s a fact that it could change a lot of lives.
What would you say if we told you that there is a brand-new technique which could make tooth loss go in history? Edward V. Zegarelli Professor of Dental Medicine, and a professor of biomedical engineering at Columbia University has developed stem cell dental implants which can grow new teeth in as little as two months. This is a huge medical advancement, particularly considering that by the age of 74, more than 26 percent of adults have lost all of their teeth.
The researchers believe that they have come up with a way to have body`s stem cells migrate to a 3-dimensional scaffold made of natural material and put in the patient`s mouth. When the stem cells colonize the scaffold, a tooth can grow and blend with the surrounding tissue. The ultimate result? A new tooth in less than two months.
This method doesn’t only eliminate the need to grow teeth in a Petri dish, but it is the first of this kind to achieve regeneration of anatomically correct teeth by using the body’s own resources. Factor in the faster recovery time and the comparatively natural process of regrowth (as opposed to implantation), and you have a massively appealing dental treatment.”
The experiment is described as follows:
“In each of 22 rats, they implanted an incisor scaffold orthotopically in mandibular incisor extraction pockets and a human molar scaffold ectopically in the dorsum.“
“They then infused the scaffolds’ microchannels with two growth factors. They also implanted growth-factor–free control scaffolds.”
“After nine weeks, they found that periodontal ligament–like fibrous tissue and new bone regenerated where the rat incisor scaffolds interfaced with native alveolar bone. The human molar scaffolds showed integration and tissue ingrowth. Researchers also found that the growth factors recruited significantly more endogenous cells and led to greater angiogenesis than did the growth-factor–free control scaffolds.”
