"And as time went by, more and more of the patient's humerus was ablated, which also led to conflicts between the patient and his family and the hospital. The patient and his family believed that it was the hospital's incorrect handling that caused these problems.
Of course the hospital argued hard, but in the face of the reality, they had to reconcile with the family members and actively search for treatment. However, in the past few years, there has been no results. The patient had several bone grafting surgeries, but none of them were successful.
was dissolved.
What's even more terrible is that the ablation on this patient's humerus is rapidly spreading to the patient's clavicle, scapula, and even ribs. The ribs and scapula have been affected, and the ribs are about to be touched.
My friend had no choice but to ask me for help. He knew that I participated in scientific research tasks related to yours, so he thought about whether he could find a way. He happened to hear about Zou Feifei's case and the related biological 3D printing technology, so
I just want to entrust me to ask you if there is any way to save this patient."
Wu Jiuzhi looked at Wu Hao after the introduction, and Wu Hao also began to think carefully after hearing this.
Xu Shenghua thought for a while and then shook his head: "This disease is very difficult, and I'm afraid there won't be a good solution for a while."
Yes, even if we use 3D bioprinting technology to print a complete set of bones for this patient for transplantation, they will still be dissolved. Zhang Qinghong also frowned and said.
Wu Hao thought for a while, and then asked Wu Jiuzhi: "Is this patient's bone just ablated? Is there any impact on other aspects?"
Wu Jiuzhi shook his head: "I asked specifically, and there was no effect. It was just that the bones were melting, and the melting speed was getting faster and faster. It was really like being infected with some bone-eating bacteria and being eaten away.
However, they are carefully examining the tests and confirming that there is no such bacteria on the patient's ablated bone residue, so it is clear that the cause of the disease cannot be found. Some experts have put forward a conjecture, whether this patient is allergic to steel nails or titanium metal.
Deck allergy. The metal molecules in the metal penetrate into the bones, causing the bones to melt.
But this is just a conjecture and has no actual theoretical basis."
When it comes to this, it is indeed possible. Many patients with idiopathic osteolysis only develop this condition after completing fracture repair surgery. Zhang Qinghong nodded with some understanding.
That's true, but there are so many patients with fractures who have no problems. Just these few cases cannot explain the problem. Wu Jiuzhi shrugged his shoulders.
It can be studied as a rare case, but at this stage, we don't have any good solutions. If we intervene, we can only try to print out the skeleton of the patient's heart, and then implant it to see the situation.
Yes. Wu Hao thought for a while and said.
What if ablation occurs again? Xu Shenghua asked.
Then the only way to change the treatment method is to change the treatment method. Wu Hao spread his hands and said: "Either replace him with a metal skeleton, or just directly amputate it, but it doesn't seem to solve the problem."
It was a bit too rough. Wu Jiuzhi complained with a smile, but he also knew that this seemed to be the only way.
In fact, there is another way. Wu Hao saw several people finish laughing, and then said: "Perhaps something can be added to the printed artificial bones later to prevent the bones from being melted away. However, it is not clear whether it can be successful.
"
Can bones really be printed? The question this time was from Zhang Qinghong, who looked at Wu Hao and asked curiously.
Wu Hao smiled and nodded: "Of course it can be printed. The material of bones is relatively simple, but it is actually very easy to print. And bones are not like tissues and organs, which have strict time limits, but they are not so strict and consume more time."
It doesn’t matter if it takes some time, you just need to print out the relevant soft tissues and so on later.”
"If this is the case, then this technology can be used in more scenarios. For example, some brain surgery patients no longer need to use titanium metal, and can completely print new skull bones for repair." Xu Shenghua nodded and said.
.
What about teeth? Can teeth also be printed? Wu Jiuzhi asked.
Wu Hao looked at Wu Jiuzhi and nodded with a smile: "Theoretically, it can be printed, but what is the difference between printed teeth and dentures? Moreover, the cost is higher, and it may not be as strong as all-ceramic teeth. In the end, it will still have to be printed.
Fasten it."
That's different. The printed teeth are more natural, and the relevant dental pulp can be completely preserved. Wu Jiuzhi shook his head and said.
Wu Hao smiled and shook his head when he heard this: "In fact, we are also studying technology in this area. Rather than printing out teeth and then installing them, it is better to study how our teeth grow."
What do you mean? After hearing Wu Hao's words, the three of them looked at Wu Hao involuntarily.
Wu Hao faced the gazes of the three people and explained with a smile.
"To put it simply, we hope to print or grow a tooth germ or tooth seed, which is what our teeth look like before they grow out. Then we can implant it directly on the gums of the patient's mouth with missing teeth, allowing the teeth to grow.
Slowly develop and grow.
In this way, patients with missing teeth can regain a set of real teeth, which are stronger, healthier and longer-lasting than dentures.”
Real dental implants?
The three of them were all startled by Wu Hao's introduction, and then they couldn't help but shake their heads. This was simply a bit whimsical, could it be like this?
In their opinion, the current dental implant technology or denture-wearing dental restoration technology is already very good. Why do Wu Hao and others still work so hard to develop this real dental implant technology.
This technology is amazing and good, but the question is is it really necessary and will anyone choose it?
However, when the three of them thought about it from the perspective of ordinary people, they suddenly understood and admired Wu Hao even more.
For each of us ordinary people, we definitely want to have our own teeth in our mouths. Who wants to wear dentures? So when there is an opportunity to let you grow straight teeth again, it is better than wearing dentures.
Much more attractive.
It is conceivable how popular this technology will be in the market once it is commercialized. If the price can be reduced by a dozen, to a price similar to the current price of teeth, I am afraid it will cause a stir in the entire field of dentistry and dental restoration.
A major change.
At that time, I am afraid that all the tools of the dentist will be abandoned. If there is a problem with the tooth, it can be completely removed, and then a new one can be implanted, and then slowly wait for it to grow back. Who else?
