mention“Dental center”, many people only think of “tooth extraction” and “dental filling”. In fact, the dental center is not the same as dentistry. The scope of diagnosis and treatment of the dental medicine center covers tumors, trauma, maxillofacial deformities and many other diseases, many of which are difficult, urgent and serious diseases that can be serious. endangering life.
2021Year2month, one person56After a 20-year-old man fell and was injured, a wooden stick accidentally penetrated the face from the lower edge of the man’s eye socket, reached the posterior wall of the pharynx and “missed” the internal carotid artery. The director of the Oral Medicine Center of the Second Hospital of Shandong University came to Qingguo to lead oral and maxillofacial care.–The professional head and neck surgery team formulated a surgical plan for emergency common carotid artery occlusion. In order to avoid secondary damage to the patient’s carotid artery by the removed wooden stick, during the operation, Lai Qingguo gently inserted his fingers into the patient’s throat wall, while feeling the pulse of the patient’s throat. internal carotid artery, he slowly withdrew the wooden stick. , successfully saving the man’s life.
While saving lives, tumors, trauma, and even infections can cause maxillofacial abnormalities, which not only affect appearance but can also lead to loss of chewing function. Repair and reconstruction of postoperative bone defects is a clinical problem in the Oral and Maxillofacial Center of the Second Hospital of Shandong University.–The Department of Head and Neck Surgery actively explores the intersection of medicine and engineering to solve challenging clinical problems.3DThe field of precise oral and maxillofacial surgery assisted by printing technology is at the national level.

Take care of your dental health:
Prevent tooth loss and accurately treat oral diseases throughout the process
Gingivitis and periodontitis are the two most clinically common oral diseases. If gingivitis is not treated in time, some patients will progress to periodontitis, with symptoms such as loosening, shifting and recession of the gums, ultimately leading to tooth loss.
The professional periodontal disease team of the Oral Medicine Center of the Second Hospital of Shandong University reminds everyone that the treatment of gingivitis requires the complete removal of plaque and tartar, as well as the elimination of factors which cause dental plaque retention and local irritation. However, when the course of the disease is long and excessive hypertrophy or hyperplasia has occurred, surgical removal is usually necessary.
If periodontitis develops, it is necessary to determine the severity of each affected tooth in the mouth according to the condition, conduct an oral examination and full body examination, and finally formulate a corresponding treatment plan .“The general principle of treatment is to emphasize early and thorough treatment to eliminate the infection. The main treatment methods include supragingival scaling, subgingival scaling, root planing and periodontal surgery. It is important to strengthen regular examination and necessary follow-up treatment said.
As the disease progresses toward the pulpal area of the tooth, root canal treatment is necessary. Root canal treatment is the last resort to save a bad tooth. It can effectively save the patient from the fate of tooth extraction.“Root canal treatment involves using special instruments to completely remove infected or necrotic pulp, clean and shape the root canal, and tightly fill the root canal with filling materials to prevent bacteria from entering the root canal and cause reinfection.” deputy chief physician of the Department of Express Dental Endodontics.
The Dental Endodontics Center of Shandong University Second Hospital has internationally advanced root canal treatment microscopic instruments, hot gutta-percha root filling instruments, root canal preparation systems, mechanical nickel-titanium root canal, pulp vitality electrometers, root canal length measuring instruments, root canal ultrasound. cleaners, etc. can perform microscopic root canal treatment. Root canal treatment can be performed on some difficult and complex root canals that are small, curved, calcified and blocked using a surgical microscope and supplemented with ultrasonic root canal instruments.
Restorative dentistry and orthodontics:
Restore the normal appearance of the oral and maxillofacial system and restore physiological functions
Defects of teeth, dentition, missing teeth and maxillofacial defects can not only lead to functional disorders such as chewing, speaking and swallowing, but also lead to a series of complications, such as occlusal disorder , tooth displacement and more missing teeth, even. dysfunction of the entire stomatognathic system.
“Dental restoration is committed to using artificial materials to make various restorations to repair various defects and restore the normal form and physiological function of the stomatognathic system.” Su Xianshuang, deputy chief physician of the Department of Oral Restoration, Center for Oral Medicine, second. Shandong University Hospital said the restorative measures include full crowns and inlays for dental defects, veneer repair, etc. ; fixed bridge, removable partial denture, implant-based prosthesis repair, etc. for teething defects; traditional full denture repair and implant-supported full denture repair for orbital defects, ear defects and nasal defects; , prosthetic ear, prosthetic nose repair and prosthetic jaw repair for mandibular defects, etc.
Many people have this problem when opening their mouthSome “clicks” are accompanied by pain, soreness and swelling when chewing, and may even prevent the mouth from closing or opening. These can be caused by dysfunction of the temporomandibular joint. “Long-term temporomandibular joint disorders can lead to facial distortion and are one of the main factors of facial asymmetry,” said Xia Yingfeng, an expert from the temporomandibular joint department of the Second Hospital Stomatology Center. from Shandong University. receives a large number of patients with joint diseases every day, using treatment methods such as bite pads, bite adjustment or bite reconstruction have achieved good therapeutic results.
For dental deformities, the Orthodontics Department of Shandong University Oral Medicine Center is equipped with advanced appliances at home and abroad, including fixed appliances, mobile appliances, functional appliances, invisible devices, etc. Zhang Lei, deputy chief physician of the Department of Orthodontics, said that currently the department can provide treatment for craniofacial growth and development malformations in children, conventional orthodontic treatment for adolescents and adults , and orthodontic treatment for developmental malformations of the facial bones in adults.–Combined treatment of orthognathic surgery, orthodontic treatment in the sequential treatment of patients with cleft lip and palate, etc.
Filling of complex missing teeth:
Remove it, crash it, repair it immediately,3DPrecise planting using printed guides
As the public’s demands for quality of life improve, dental implants are becoming more and more popular.The life of “toothless people”. The Oral Implantology Department of the Oral Medicine Center of the Second Hospital of Shandong University took the initiative to develop complex dental implant technology in Shandong Province, allowing more patients to enjoy the comfort and of the convenience of dental implants.
Not long ago, the team of dental implantology professionals continued to3performed on elderly patients3DImmediate extraction, immediate implantation and immediate repair of half-mouth implant surgery assisted by printed guides,3In total, 2 elderly people were implanted21implant.

“A conventional implant prosthesis restoration treatment cycle requires at least6For older people with underlying diseases, the treatment cycle often needs to be extended due to poor general physical conditions. “Lai Qingguo said that the technology of immediate extraction, immediate implantation and immediate repair has become good news for elderly patients.
Instant Extract, Instant Plant and Instant Repair technology uses only1Repairing defective teeth can be completed in just one day, which can shorten patients’ waiting time for bone healing, reduce the number of medical visits, avoid the long period of patient missing teeth, and maintain the good shape of the gums. . At the same time, under the guidance of the original extraction socket, the implant can be implanted in the ideal anatomical position and is more consistent with the transmission of biting force.
exist3DWith printed implant guides, the therapeutic effect of immediate extraction, immediate planting and immediate repair has been taken to a higher level. “By simulating the occlusion relationship before surgery, we can determine the implant placement plane and use guide plates to accurately implant implants during surgery, which can shorten the operation time and reduce the surgical trauma,” Lai Qingguo explained.
