Craniofacial surgery: customised bone implants grown inside the patient

dfdfdPatients who suffer loss of jaw bone are left with bony defects that are both aesthetically and functionally challenging. Researchers from Rice University in the United States have developed a technique to generate engineered tissue customised to specific defects by implanting a 3D-printed bioreactor against a rib. The stem cells and blood vessels from the rib grow a natural bone material that is tailored to the patient and can be transplanted to the face.
The goal of the research was to advance craniofacial reconstruction by taking advantage of the body’s natural healing powers. The technique has been developed to replace current reconstruction techniques that use autogenous bone graft tissue.
“A major innovation of this work is leveraging a 3D-printed bioreactor to form bone grown in another part of the body while we prime the defect to accept the newly generated tissue,” said co-author Dr Antonios Mikos, Louis Calder Professor of Bioengineering and Chemical and Biomolecular Engineering at the university.
The researchers made a rectangular defect in the jaw bones of sheep. They created a template for 3D printing and printed an implantable mould and a spacer, both made of bone cement. The goal of the spacer was to promote healing and prevent scar tissue from filling the defect site.
The mould stayed in place for nine weeks before removal and transfer to the site of the defect, replacing the spacer. In the animal models, the new bone knitted to the old and soft tissue grew around and covered the site.

Promising new treatment could regenerate gum tissue and prevent tooth loss

dfdfdWhen left untreated, the consequences of gum disease can become irreversible. Now, a new procedure could treat the problem. In a new study, scientists have been able to combine biological and mechanical techniques to repair and regenerate bone and gum tissue.
Long-standing gum disease often turns into periodontal disease, affecting the tissues supporting the teeth. As the disease gets worse, the bone anchoring the teeth in the jaw wears away and tooth loss occurs.
To treat the condition, researchers surgically implanted a thin, film-like membrane between the inflamed gum and tooth. This membrane blocks the infection from the gums and delivers antibiotics, medication and growth factors to the gum tissue.
Dr Nigel Carter OBE, Chief Executive of the Oral Health Foundation, describes the impact of tooth loss and believes the research could be extremely promising: “Millions of people across the world lose teeth from periodontitis and it can have severe bearing on everyday life. Missing teeth can make eating, smiling and speaking more difficult. It can also have an impact on our confidence and mental well-being, as well as increase the risk of developing general health problems.
“Scientific breakthroughs in similar fields have already led to developments in many other areas of healthcare, such as prosthetics and tissue regeneration. These have helped millions of people gain a better quality of life and this cutting-edge research has the potential to do the same in the future. This study has significant potential and we shall look forward to human trials.”

Researchers discover new material that could make dental fillings more durable

dfdfdA team of researchers at the Oregon Health & Science University (OHSU) School of Dentistry in the United States has created a filling material that is twice as resistant to breakage than conventional fillings. The new filling material uses the additive thiourethane, which can also be found in protective coatings for cars and wood decks.
The team has also developed an adhesive that proved to be three times stronger after six months in use than the adhesives that are currently used to keep fillings in place. Combined, the new adhesive and the filling material are designed to make more enduring dental restorations.
“Today’s dental restorations typically only last seven to ten years before they fail,” said Dr Carmem Pfeifer, corresponding author of the studies. “They crack under the pressure of chewing, or have gaps form between the filling and the tooth, which allow bacteria to seep in and a new cavity to form.”
“Every time this happens, the tooth under the restorations becomes weaker and weaker, and what starts as a small cavity may end up with root canal damage, a lost tooth or even life-threatening infections.”
The dental adhesive uses a type of polymer, known as (meth)acrylamide, that is much more resistant to damage in water, bacteria and enzymes in the mouth than the standard adhesives currently used in the dental industry. The filling material uses thiourethane, a chemical compound that can better withstand chewing.
The studies were published in the journals Dental Materials and Scientific Reports.
