1. Orthopaedics: exact modification, reshaping of a bone condition.
Professor Li Zan's Hunan Cancer Hospital team reconstructed the damaged thorax of late breast cancer patient Grandma. She is using a 3D-printed titanium alloy stent. Thanks to 3D printing technology using metal, intricate constructions challenging to repair with conventional surgery have become a reality. Apart from guaranteeing mechanical support, the stent's porous structural design guarantees space for tissue development. Grandma She not only recovered confidence in life but also her chest capacity following surgery.
The hand surgical team at Harbin Fifth Hospital used 3D-printed tantalum metal prostheses to precisely repair the tibial bone abnormalities of 18-year-old Xiao Liu, which resulted from an automobile accident. Tantalum metal, with its great biocompatibility and surface pore structure, helps stimulate bone regeneration and tight bonding; Xiao Liu healed well and recovered quickly after the surgery.
Medical professionals from Jining Aid Xinjiang underwent severe outer knee joint replacement surgery at Yingjisha County People's Hospital using 3D printing technology. Personalized surgical plans were developed, and the three-dimensional structure of the bones was rebuilt using preoperative, high-precision CT scanning. The operation effectively completed the joint replacement in just 78 minutes thanks to 3D printing technology using a guide plate. The day following the procedure, the patient could walk unaided.
2. Dental field: customised repairs; blossoming confident smiles.
Over a million dental components, including crowns, bridges, and more, Huashu High tech and its partners have produced using metal 3D printing technology. Mass-customised production guarantees the exact adaptation of every component and increases efficiency as well.
Entulism of complete restoration: Using 3D printed titanium plates, the team in oral and maxillofacial surgery at Qingdao University Affiliated Hospital operated on Mr. Wang, a patient with total edentulism. With a better fit and much enhanced surgical accuracy, 3D-printed titanium plates replicate the form of the patient's jawbone ahead of time. Following surgery, Mr. Wang wore a full denture with a favourable bite relationship, recovering chewing ability, and facial attractiveness.
3. Cardiovascular field: exact policy execution, complicated lesions
Helping with cardiac surgery: Using 3D printing heart technology, the Cardiovascular Centre of the Second Affiliated Hospital of Southern Medical University replicates the heart and surrounding tissue structure of complicated heart disease patient Xiaowang 1:1. The doctor practiced the surgery on the 3D model to find the key steps needed to successfully remove the fake aneurysm around Xiaowang's windpipe and food pipe, which helped fix the swallowing and breathing issues he had for many years.
The team from Xijing Hospital, led by Professor Yang Jian, finished the transcatheter aortic valve implantation procedure using 3D printing technology. The scientists precisely placed domestic heart valves using 3D printing models in response to the patient's unusual anatomical shape, therefore improving the hemodynamics.
4. Technical focus The technical focus provides an ideal blend of exact control and personalisation abilities.
Using the patient's CT/MRI data, 3D printing technology with metal precisely matches implants to the anatomical structure, achieving true "tailoring."
Complex structure manufacturing can create challenging porous shapes and biomimetic joints, which helps make implants more compatible with the body and improves their strength using different methods.
Precise control of small details, like porosity and pore size, will improve how well cells stick and support blood vessel growth around implants.
5. Clinical value Boost efficiency; cut rehabilitation time.
Surgical simulation uses preoperative 3D printing models to improve surgical accuracy and safety, thereby reducing complications.
Personalised implants can minimise rehabilitation time by better integrating with human tissues, encouraging bone growth and wound healing, and thus promoting recovery of any kind.
Helping patients reestablish normal physiological processes and appearance will assist them in improving their quality of life and gaining confidence in it once more.
