After four years of intensive research by the Netherlands Cancer Institute and the Dutch Mobius 3D Technology (M3DT), a titanium lower jaw was implanted for the first time in a head and neck cancer patient. The jaw was completely reconstructed based on the patient's 3D MRI & CT scans. The operation was successful. https://medicalxpress.com/news/2022-08-successful-custom-3d-printed-titanium-jaw.html Thu, 04 Aug 2022 10:20:38 EDT news578827236 Botox injections to manage jaw and facial pain do not result in clinically significant changes in jaw bone when used short term and in low doses, according to researchers at NYU College of Dentistry. However, they found evidence of bone loss when higher doses were used. https://medicalxpress.com/news/2020-09-botox-tmj-disorders-bone-loss.html Mon, 14 Sep 2020 14:18:54 EDT news519311922 USC researchers and collaborators report a breakthrough to prevent damage to the jaw, a side effect suffered by some people undergoing treatment for cancer or osteoporosis. https://medicalxpress.com/news/2019-04-jaw-patients-cancer-osteoporosis.html Thu, 11 Apr 2019 08:11:29 EDT news474189081 A technique using umbilical cord blood stem cells could be a promising new approach for repair of cleft palate in infants, reports a paper in The Journal of Craniofacial Surgery. https://medicalxpress.com/news/2018-10-technique-umbilical-cord-stem-cells.html Wed, 03 Oct 2018 02:24:29 EDT news457752261 The absence of a protein critical to the control of inflammation may lead to rapid and severe bone loss, according to a new University at Buffalo study. https://medicalxpress.com/news/2018-03-absence-key-protein-ttp-rapidly.html Sat, 10 Mar 2018 03:15:41 EST news439874085 A review of more than a decade's worth of research on osteonecrosis of the jaw—when the bone in the jaw is exposed and begins to starve from a lack of blood—points to an increased risk for patients taking certain drugs for osteoporosis, anticancer drugs or glucocorticoids, those undergoing dental surgery, and people with poor oral hygiene, chronic inflammation, diabetes, or ill-fitting dentures. https://medicalxpress.com/news/2014-12-highlights-ways-jaw-bone-disease.html Mon, 15 Dec 2014 16:20:20 EST news337882812 Surgeons in Mumbai have removed 232 teeth from the mouth of an Indian teenager in what they believe may be a world-record operation, the hospital said Thursday. https://medicalxpress.com/news/2014-07-surgeons-teeth-indian-teenager.html Thu, 24 Jul 2014 03:54:20 EDT news325392848 A technique called distraction osteogenesis can create increased length of the upper jaw in patients with cleft lip and palate deformities, reports a study in the March issue of The Journal of Craniofacial Surgery, edited by Mutaz B.

Current implant-based methods of whole tooth replacement fail to reproduce a natural root structure and as a consequence of the friction from eating and other jaw movement, loss of jaw bone can occur around the implant. The research is led by Professor Paul Sharpe, an expert in craniofacial development and stem cell biology at King's College London and published in the Journal of Dental Research. https://medicalxpress.com/news/2013-03-biological-tooth-replacementa-closer.html Sat, 09 Mar 2013 04:29:44 EST news282025776 Adelaide scientists have found that mice with gum disease develop worse arthritis. https://medicalxpress.com/news/2012-10-relationship-gum-disease-arthritis.html Tue, 16 Oct 2012 07:57:52 EDT news269593062 Using a novel surgical approach, it's possible to rebuild a functional lower jaw and mouth, and preserve a patient's ability to eat and speak after removing an invasive facial tumor, according to a new report from Henry Ford Hospital in Detroit. https://medicalxpress.com/news/2012-09-surgery-rare-tumor-rebuilds-jaw.html Fri, 07 Sep 2012 13:24:39 EDT news266243073 Researchers at the Columbia University College of Dental Medicine have identified a genetic variation that raises the risk of developing serious necrotic jaw bone lesions in patients who take bisphosphonates, a common class of osteoclastic inhibitors. The discovery paves the way for a genetic screening test to determine who can safely take these drugs.
