Zhang Siyuan found clean water, cleaned the two teeth, took out an alcohol cotton ball and wiped it on the surface of the tooth for disinfection, and then took out a magnifying glass and other equipment to observe it carefully.

After a while, she put down the tool in her hand and said, "This tooth on the left has been filled, and the one on the right is interesting, it is a denture." ”

"Dentures?" Lin Yuhan frowned slightly.

Although he had already sensed that there was something abnormal about this tooth in advance, he didn't expect it to be fake. Are all the dentures made so realistically?

Lin Yuhan asked, "Can you find out which hospital these two teeth were made in?" ”

"What?" Zhang Siyuan's eyes widened, "Brother, you are teasing me, there are so many dental hospitals in Lanhai City, you just rely on two broken teeth and let me help you investigate, this is impossible!" ”

Lin Yuhan pondered in a low voice.

Zhang Siyuan's complaint has some truth, after all, there are too many people who see teeth every day, so it is really impossible to investigate.

However, he always felt that any clue could be a path to the truth, but sometimes it was in the wrong direction.

Now that you know the characteristics of your teeth, you may be able to think differently about the problem.

After a while, Lin Yuhan continued to ask, "Then can you find out the materials used to make these two teeth?" ”

"This ...... It should be ok. Zhang Siyuan thought for a while and explained, "There are only a few materials for fillings, and the most commonly used material now is resin, and this denture looks like it is all-porcelain from the outside, so I need to use a scanner to detect it, wait a minute." ”

She picked up her two teeth and walked into the testing room.

After a long time, Zhang Siyuan came out of it and said: "This repaired incisor is made of nano resin material imported from the United States, to be honest, because the price is too high and fewer people use it, so this material is not common." And this molar, the cost is even higher. ”

She pushed the thing in front of Lin Yuhan: "If I'm not mistaken, this tooth should be a zirconia all-ceramic tooth, using the latest generation of computer-aided design automatic mechanical cutting technology, so the shape will be so realistic." ”

"What's the matter?"

"It requires a very high-end device called a 3D oral scanner. It is to scan the inside of your mouth with a computer to show a 3D effect of the teeth in your mouth. Every detail of the tooth can be seen and then repaired or modeled, making it ideal for designing premolars in the prejaw, with unrivalled light transmission and strength, resulting in a highly realistic tooth for optimal aesthetic results. ”

"Can you do it here?"

"I can't do it so well," Zhang Siyuan shook his head slightly embarrassed, "This is the most high-end equipment on the market now." It's too expensive to afford. As far as I know, there are only two hospitals in the entire city of Lanhai that can do it. And this material is like the Lava all-ceramic tooth imported from the United States, which is currently a first-class brand in the world, with a unit price of more than 20,000 yuan. ”

Lin Yuhan showed a relieved smile: "There are still things that your family can't afford?" ”

"It's just not very useful." Zhang Siyuan's words revealed the atmosphere of a local tyrant, "If you really want to buy it, it's not impossible." It's just a million on equipment, because the cost of tooth making is too high and expensive, there are very few people who use this technology to make teeth every year, and it would be good for me to meet one or two. Doing business should pay attention to the ratio of investment and return, and the cost of equipment is difficult to recover, so it is better not to use it. I am a small clinic and the existing equipment is enough to meet the needs of most patients. ”

"I see."

Zhang Siyuan continued: "This equipment is only available in large hospitals like Lanhai Central Hospital, and there is also Yikang Dental Clinic, the most high-end private dental hospital in Lanhai City. Nowhere else, I don't think you can get such a high-end thing. ”

"Great!" Lin Yuhan had a feeling of sudden enlightenment, "Therefore, at present, our scope can be locked to patients who have undergone surgery in these two hospitals. ”

"And he must be very rich." Zhang Siyuan added.

"You make so much sense! After so many years, your thinking is still so clear, compared with when you were in school, your demeanor has not diminished! Lin Yuhan looked meaningfully at the dentist beauty beside him, "It's so useful to have a classmate like you!" ”

Touching the ill-intentioned gaze, Zhang Siyuan asked vigilantly: "What are you doing?" ”

"Hehe......" Lin Yuhan showed his slightly lewd smile.

Zhang Siyuan seemed to understand, and his tone became excited: "You don't want me to help you ask for patient information from these two hospitals, right?" ”

"Why are you so smart? I remember, you used to do an internship in a downtown hospital? You should know a lot of relationships, right? ”

"Don't think!" She raised her eyebrows, "The information of patients in each hospital is confidential, how can you just watch it!" Do you think I'll give it to someone if I want it? ”

"Do me a favor, you are so beautiful, shrewd and capable, I believe you must have that strength!" Lin Yuhan complimented, "Just once, I set up a big case, and when the case is closed, I will invite you to dinner." ”

Zhang Siyuan bit her lower lip and showed a bitter smile, finally, she took out a piece of paper, quickly wrote down a number, and handed it to Lin Yuhan: "This, it is Director Wang of Dentistry of the Central Hospital, you contact him and say that I introduced him." On the Yikang side, you have to figure out your own way, after all, we are competitive, and it is impossible to share customer information. But you're a detective, and I'm sure you have that ability, as long as you ...... Use some means. ”

"Thank you so much!" Lin Yuhan put the note in his pocket, "Then I won't bother you, farewell." ”

I got up and couldn't wait to walk towards the door.

"You're just leaving?" Zhang Siyuan seems to have unfinished meaning.

"You have an appointment with a patient, and you can't afford to delay your time. Thank you for giving me so much valid information. It helped me a lot, we'll talk about it later. ”

Lin Yuhan got into a taxi, leaving behind the beautiful woman who was stomping her feet behind.

Many times, he also felt that he seemed to be a little unapproachable.

Lanhai Central Hospital, inside the office of the director of the Department of Stomatology.

Lin Yuhan met a middle-aged man in his forties and fifties. With a pair of gold-rimmed glasses, he looks kind and heroic.

He has a work sign on his chest: Wang Yueran, director of the Department of Stomatology at Lanhai Central Hospital.

Wang Yueran's office is spacious and bright, and one wall is covered with pennants such as "Dental Skill, Virtue and Medicine", "Superb Medical Skills, Extraordinary Shots", etc., which is enough to show Wang Yueran's status in the medical community of Lanhai City.

On the other wall is a pattern of the human mouth, the noun of each part is explained, and the cabinet next to it is placed with a model of teeth or dentures, fillings and other related display products.
