Qianhai Shekou Free Trade Zone Hospital independently designed and printed digital 3D implant guide plate to open a new era of precision minimally invasive dental implants_Shenzhen News Network

Shenzhen News Network, October 12, 2021 (Reporter Wang Zhiming) Miss Shen, a citizen, has been suffering from sour and easy-to-embed foods for more than ten years due to the damaged caries in her lower right teeth. But because she was afraid of pain, she also did not dare to remove the decayed teeth and implant them. After inquiring from many parties, she learned that the Department of Stomatology of Qianhai Shekou Free Trade Zone Hospital has carried out digital diagnosis and treatment technology for more than 7 years, and she went to the stomatology department of the hospital with both anxiety and expectation. After receiving Ms. Shen, Dr. Li Long, a stomatologist at the hospital, carefully analyzed the CT data scan and asked Ms. Shen's medical history and needs in detail, he suggested that the hospital independently designed and printed a digital 3D implant guide. After CT data scanning and computer accurate design of the implantation location of the full mouth implant of the lower jaw, the 3D printing equipment is used to manufacture an individual implant guide plate. This solution enables precise minimally invasive implantation, improving surgical efficiency and shortening healing time. Independent design, the first Pengcheng Public Hospital new way of implanting dental Dr. Li Long introduced, at present, most of the implant guide boards in the clinic need to be designed and produced by denture processing plants before they can be applied to the clinic. The design and processing of the guide plate takes 1 to 2 weeks, the patient waits for implant surgery for a relatively long time, and the denture processing plant guide plate production cost is expensive, about 2000 3000 yuan. Relying on the hospital's 3D printing clinical transformation application and regenerative medicine innovation center and Liang Hai labor model and artisan talent innovation studio, Dr. Li Long and Dr. Lin Zhengjie of the 3D printing innovation center work together, one is responsible for the pre-design, and the other is responsible for the post-3D printing production. In Shenzhen public hospitals, it is the first to realize the independent design and printing and production of 3D implant guide plates, the fastest 3 hours to complete the production of guide plates, the implantation surgery time is shortened by 20%, the cost of guide plate production is reduced to 500 800 yuan, and the dental implants on the same day of patient visits are realized (if eligible). At present, there is an endless stream of patients who have made appointments for this new method of implantation, and in just 1 week, the hospital has completed 8 cases of this implant surgery. It is understood that at present, there are not many dental hospitals in the country that can independently design digital 3D guide plate dental implants, and Qianhai Shekou Free Trade Zone Hospital is currently the first public hospital in Guangdong Province to have a digital implant one-stop processing center medical institution, combined with the expert team and technical team, which has been precipitated in this field for seven years, and the precise control of the whole surgical process minimizes the surgical time and surgical trauma, and realizes the perfect repair of missing teeth. Liang Hai, director of the Department of Stomatology, who leads the new trend of dental implants in Pengcheng, introduced that digital implantation is an efficient, minimally invasive and accurate technology that assists stomatologists in implant restoration by means of digital means, and is the development trend of oral clinical implantation, and implant guide plate technology is one of the mainstream clinical digital technologies at present, which is particularly suitable for edentless jaw and zygomatic implantation. The Department of Stomatology of the Hospital has been carrying out digital diagnosis and treatment technology for more than 7 years, and at the same time, oral implant guide plate and implant navigation technology have also been carried out for many years. The department has now cultivated a team of proficient digital technology and has a full set of digital equipment: 3 shape3 D planting guide plate independent design and printing production integration. Inlay and full crown, c ad/cam chairside cutting system, 3D implant guide plate production, dental model printing equipment, domestic advanced implant navigation equipment, laser treatment instrument and root canal microscope. This time, the 3D planting guide plate independent design and printing production integration, it makes the patient from the reception to the completion of the processing of the guide, only 3 hours to complete the design and production. This not only greatly improves the efficiency of the dentist's visit, reduces the waiting time of patients, but also greatly saves the cost of making guide plates and the cost of patient treatment. "The application of digital implant mode breaks the traditional procedures of mold taking, filling mold, carving wax, porcelain and other traditional procedures, using three-dimensional scanning, computer-aided design and production, and then reconstructing the digital model of teeth and alveolar bone through the computer, from the acquisition of preoperative three-dimensional image data, computer-aided implant surgery to postoperative implant prosthesis design and processing, with the support of digital technology, preoperative precise design, intraoperative accurate control, postoperative exquisite repair, improving the accuracy of implant treatment and reducing human error. It improves the predictability of implant treatment, reduces the risk of complications, realizes the coherence and reproducibility of each treatment procedure in the implant treatment process, and realizes the implant treatment concept of restoration-oriented function and aesthetic effect. Liang Hai said in advance planning, layout of medical transformation of the new blue ocean In recent years, the hospital gave full play to the "three-zone advantages" of the Qianhai Shekou Free Trade Zone, and in March this year, in cooperation with the academician team of Academician Lu Bingheng of the National Additive Manufacturing Innovation Center of Xi'an Jiaotong University, the 3D printing clinical transformation application and regenerative medicine innovation center (hereinafter referred to as the "3D printing innovation center") was established to lay out the biomedical collaborative innovation technology transformation and application platform in advance. Luo Xudong, secretary of the party committee of the hospital, said that according to the patient's medical tomography image, adhering to the medical concept of digitalization, individualization, precision and networking, working closely with the clinical department, using 3D printing technology, providing personalized surgical program planning, design and manufacturing of personalized innovative medical devices, etc. are actively applied to the clinic, which is not only conducive to improving the accuracy of treatment, but also conducive to reducing surgical risks, greatly improving the level of medical services, reducing the cost of diagnosis and treatment of patients, and bringing tangible health benefits to the majority of patients. He stressed that based on the Qianhai Shenzhen-Hong Kong Service Cooperation Zone riding the "policy" Dongfeng and drawing on the "combination of medical and industrial" model, the hospital's 3D printing innovation center is committed to building a first-class additive manufacturing (3D printing) medical center, personalized medical device application center, medical 3D printing material research center, rehabilitation assistive device 3D printing research and application center, 3D printing medical testing and inspection center and medical additive manufacturing training base in the Guangdong-Hong Kong-Macao Greater Bay Area. According to Dr. Lin Zhengjie, head of the 3D Printing Clinical Transformation and Regenerative Medicine Innovation Center, the 3D Printing Innovation Center of the hospital covers an area of 310 square meters, and has 17 core equipment such as metal 3D printers, light-curing 3D printers, high-performance PEEK material printers, full-color 3D printers, oral resin printers, FDM printers, etc., and has cooperated with the hospital's neurosurgery, orthopedics, stomatology, breast surgery and other departments to design complex surgical case models and personalized surgical guides for more than 50 cases. At present, it is cooperating with the breast tumor prevention and treatment team of Academician Song Erwei of Sun Yat-sen Memorial Hospital of Sun Yat-sen University to develop a new type of degradable breast reconstruction stent and individualized breast tumor removal mold.
