Recently, researchers in Singapore invented a 3D printed stent that can grow bones and can be used for dental implants placed after the patient's teeth are removed. This is said to eliminate the need for painful bone grafts because previously used bones are often taken from other parts of the patient's body.
It is understood that this 3D printing bracket was developed by the doctors of the National Dental Center of Singapore (NDCS) and the bioengineers of Nanyang Polytechnic (NTU) over the past five years.
Researchers say it "is the world's first in terms of design and materials," and plans to officially launch the 3D printed stent after the completion of the second round of clinical trials involving 132 patients, estimated to be around three. After the year.
Currently, the researchers have succeeded in the first round of clinical trials for seven patients.
Dr. Goh Bee Tin, deputy director of research and education at NDCS, said the invention is particularly practical because the number of patients with tooth decay and periodontal disease in Singapore is expected to increase due to the ageing population.
It is reported that the scaffold is made of a porous synthetic material, which will place the osteoblasts in the teeth of the tooth that has been extracted, and it is more convenient to promote bone growth than the bone substitute from animals or human body. effective.
“Bone replacement materials often take a long time to be absorbed by the body,†Dr. Goh said. “In contrast, this stent is fully absorbed by the body and not only absorbs much faster, it is also cheaper to manufacture.â€
