These dental implants rely heavily on the presence of a structured alveolar ridge, as the titanium screw used for fixation requires a specific dimension for insertion.

About five years ago. In the beginning I was skeptical: why should I preserve the ridge, if I could also wait and do implant placement with simultaneous GBR later on?

The study of robotics has been known to yield benefits for humans in a variety of ways; however, a new research study suggests possible benefits but on a different scale.

A major hurdle to using neural stem cells derived from genetically different donors to replace damaged or destroyed tissues, such as in a spinal cord injury, has been the persistent rejection of the introduced material (cells), necessitating the use of complex drugs and techniques to suppress the host’s immune response.

Cardiovascular regeneration focuses on repairing or replacing damaged or senescent cardiac and vascular tissue.

Despite the promising neuro-regenerative capacities of stem cells, there is currently no licensed stem cell-based product in the repair and regeneration of peripheral nerve injuries. Here, we explored the potential use of human gingiva-derived mesenchymal stem cells (GMSCs) as the only cellular component in 3D bio-printed scaffold-free neural constructs that were transplantable to bridge facial nerve defects in rats.

Regenerative medicine is a branch of translational research in tissue engineering and molecular biology which deals with the process of replacing, engineering or regenerating human cells, tissues or organs to restore or establish normal function.

A Purdue University-affiliated startup has devised a way to map arteries in the roof of a person’s mouth to help avoid complications and improve outcomes in oral surgery.

Geistlich invested heavily to develop its latest product, the 3D collagen matrix Geistlich Fibro-Gide^®. Dr. Terance Hart, Director Research, and Dr. Mark Spilker, Chief Scientific Officer, talk about innovation, research pathways and strategic collaborations.

Although connective tissue grafts are the gold standard when it comes to soft tissue augmentation their use is associated with several issues such as anatomical restrictions^1-3 or pain and numbness at the donor site^4,5.

Robert E. Guldberg, the incoming executive director of the Phil and Penny Knight Campus for Accelerating Scientific Impact, will introduce the campus community to his research in an upcoming public talk.

Newly identified stem cells in the lung that multiply rapidly after a pulmonary injury may offer an opportunity for innovative future treatments that harness the body’s ability to regenerate.

Fujifilm Global and Takeda Oncology recently announced a collaboration to develop regenerative medicine therapies for the treatment of heart failure using induced pluripotent stem cell (iPSC)-derived cardiomyocytes.

Biodegradable polymeric scaffolds have been used for tissue engineering approaches and can be used to regenerate temporomandibular joint (TMJ) tissues.

The University of Florida has launched a Center for Regenerative Medicine to develop lifesaving therapies “to heal the body from within” using stem cells that repair damaged tissue and organs.

Non-genetic induction of somatic cells into neural crest stem-like cells (NCSCs) is promising for potential cell-based therapies for post-traumatic peripheral nerve regeneration.

A method of making bioink droplets to stick to each other using an enzyme driven crosslinking method has been developed by researchers from Osaka University

When newts lose a leg, they regenerate a new one.  Even destroyed cardiac tissue is swiftly replaced by healthy tissue. What is the underlying mechanism?

Since 2010 global demographics have revealed an ever-increasing elderly population.

Aged patients, who tend to present with partial or total tooth loss, inevitably need more complex and higher quality dental rehabilitation, including dental implant therapy.

Regenerative surgical procedures have long been considered a suitable method for restoring lost periodontal structure and functional attachment.

The evolution of head and neck reconstruction dates to approximately 1000 BC, when Sushruta, the father of Indian surgery, introduced the
the theory for arguably the first regional pedicled flap in rhinoplasty. Ancient Egyptian, Greek, Persian, and Indian civilizations expanded on this medical marvel by contributing to discoveries in human anatomy, whereas Roman physicians described possibilities for local tissue rearrangements for nearly all segments of the face.

Jaw Surgery is performed to correct various problems related to the jaw, facial appearance, and other maxillofacial problems.

First peri-implantitis occurs, then alveolitis following explantation. How should this case be treated?

Bone is comprised of a mineral and protein scaffold filled with bone cells.

Bisphosphonates and other antiresorptives have been used in various bone diseases for many years.

Although bone morphogenetic protein-2 (BMP2) has demonstrated extraordinary potential in bone formation, its clinical applications require supraphysiological milligram-level doses that increase postoperative inflammation and inappropriate adipogenesis, resulting in well-documented life threatening cervical swelling and cyst-like bone formation.

Rapid bioorthogonal reactivity can be induced by controllable, catalytic stimuli using air as the oxidant.
