One of the major differences between the treatment of dental and maxillofacial tissue defects and the treatment of other diseases is that the patient receives a prosthesis after the treatment. This restoration gives some friends the feeling that “the restoration is a commodity bought with money”. Although restorations for repairing various tissue defects cost a certain amount of money, you should not treat them as a commodity, and you should not treat “treatment for repairing various tissue defects” as a “purchase”. You should know that: 1) some restorations may look similar, but in reality they vary from person to person; 2) making restorations requires cutting and grinding of oral tissues, and the tissues removed cannot be restored; 3) proper restorative surgery and restorations are good for maintaining and improving health, while incorrect restorative surgery and restorations will directly damage health or create health risks. Therefore, before you undergo treatment to restore tooth and oral and maxillofacial tissue defects, you may want to pay attention to the following entries and related matters. As far as you and your friends know, does the medical facility you are going to have the facilities to treat your disease without getting infected or causing new diseases? If something happens during treatment, you won’t miss anything there, right? Did your friends who received treatment there over the years feel at ease? Are you satisfied? Also, do you have a medical staff that you can trust to look out for you and be able to relieve your pain? If so, that’s the place to go! 2. Trusted treatment plan The oral and maxillofacial tissues are very complex and repairing defects is not an easy task. In the case of teeth, for example, tooth loss is often accompanied by different pulpal, periodontal and adjacent tooth abnormalities, and the situation with missing teeth is even more complex. A good treatment plan is necessary to obtain a better restorative treatment result. Is the treatment plan trustworthy? This may be difficult for non-medical practitioners and non-professionals, and can be indirectly seen in the following aspects. (1) whether you are given a thorough oral examination to explain the current status of your mouth in relation to the restorative treatment; (2) whether you are given a clear diagnosis, which involves not only missing teeth but also other diseases related to oral health; (3) whether you are informed of the current status of your mouth and its relation to the restorative treatment; (4) observe your receiving physician’s attitude towards your tooth stumps and root remnants, whether he advocates extraction because of the difficulty of treatment or does his best to (5) Observe the attitude of your practitioner towards periodontal disease, whether he advocates extraction for fear of risk or preservation for comprehensive use; (6) Observe the attitude of your practitioner towards pulp vitality, whether you are told that “pulp has to be removed to make a fixed tooth. There is nothing wrong with removing the pulp” or being told that he will do his best to protect the vitality of your pulp; (7) There are often multiple restorative options for the current status of the defect. (8) After the treatment plan is determined, listen to your receiving physician to introduce the results of treatment and quality commitment. (3) Trusted quality control system The establishment and effective implementation of a system to ensure the quality of medical care is very important for the safety of patients’ lives and medical outcomes. Generally speaking, except for emergencies, we should choose hospitals with good medical ethics, strong academic atmosphere, sound rules and regulations, and long-standing presence of higher medical and health authorities to ask questions and inspect. 4.Trustworthy treatment cost The treatment cost is closely related to the treatment plan. The cost of repairing teeth as well as oral tissue defect treatment mainly consists of the following factors: fixed medical facility utilization fee, clinical diagnosis fee, restoration design fee, treatment fee, restoration material fee, restoration processing fee, etc. The medical equipment and materials used vary, and the same type of restoration may vary from one level of hospital to another. It is understandable that the cost of treatment at a lower level hospital is lower than that of a higher level hospital. It is important to note that before receiving treatment, you should find out the overall cost of completing the entire restorative treatment, i.e., until the restoration is completed, including a follow-up visit. Don’t be unaware of the cost before treatment, and then add up the cost during treatment, and be stumped at the time of settlement! If the restoration of missing teeth and oral and maxillofacial tissue defects is regarded as the construction of a tall building, then the pre-prosthetic oral examination and basic treatment is to survey the foundation for the building and lay the foundation. The foundation work before restoration includes the following main elements: 1. a comprehensive oral examination, paying special attention to the teeth in contact with the future restorations to exclude their various disorders; 2. if the teeth in contact with the future restorations have pain themselves such as caries, endodontic disease, periapical disease, etc., they should be treated before restoration. If the tooth in contact with the future restoration is loose and bleeds easily, such as periodontal disease, it should be treated before restoration and restoration should be done after periodontal disease is controlled; 4. If there are sharp bone tips, bone protrusions, bone ridges, etc. on the alveolar bone in contact with the future restorations, they should be surgically trimmed before restoring the missing teeth to prevent pressure and pain when wearing dentures; 6. If there is a lot of soft scale or calculus on the surface of the remaining teeth in your mouth, they should be thoroughly cleaned and removed before restoration to maintain the health of the remaining teeth. Third, for the restoration of missing teeth to prepare time for restoration The treatment of dental defects, missing teeth and oral and maxillofacial tissue defects has similarities with surgery, such as detailed preoperative examination, accurate diagnosis, adequate preoperative preparation, meticulous intraoperative, close observation and proper solution of various postoperative problems, but it is more demanding and complicated than general surgery, and most of the oral restorative treatment cannot be completed in one visit. The following can be used as a reference for the time preparation for repairing different defects: 1. Because of full mouth tooth loss for full denture restoration, four visits are generally required. The first visit is for oral examination, diagnosis, and impressions. The second visit is used to determine the alignment of the future maxillary and mandibular complete denture. The third visit is for initial placement of the full denture. The fourth visit is for review and resolution of discomfort after initial wear of the full denture; 2. 3 to 4 visits are generally required for cast bracket removable partial denture restoration because of many missing teeth. The first visit is for oral examination, diagnosis, denture design, preparation of the denture component space, and making impressions. The second visit is to try the metal bracket. The third visit is for initial denture placement. If there is any discomfort after the first wearing of the denture, it is necessary to visit the clinic again to check and solve the problem; 3. The first visit is for oral examination, diagnosis, denture design, and appointment of the date of fixed denture restoration. The second visit is to prepare the space for the fixed denture components, make an impression, and create and wear a temporary fixed denture. The third visit to wear a fixed denture; 4. At least five visits are required for implant prosthetics due to individual tooth loss. The first visit is for oral examination, diagnosis, treatment planning and appointment for implant surgery. The second visit for implant surgery. The third visit is for the placement of the implant superstructure. The fourth visit is for taking impressions, making and wearing temporary restorations. The fifth visit for permanent restorations (porcelain crowns, porcelain fixed bridges, etc.). After the implant restoration, a follow-up visit should be made at least once every six months to check and resolve any discomfort after the implant restoration; 5. 3 visits are generally required for the restoration of piles and artificial crowns (all-ceramic crowns, porcelain crowns, metal crowns) due to severe tooth loss. The first visit is for oral examination, diagnosis, artificial crown design, preparation of pile space, and making impressions for making pile cores. The second visit is to wear the pile core and make the impression for the artificial crown. The third visit to wear artificial crowns; 6, because of poor tooth color or bad shape for artificial crowns (all-ceramic crowns, porcelain crowns, metal crowns) restoration, generally need to visit 2 times. The first visit for oral examination, diagnosis, artificial crown design, preparation of artificial crown gap, making impressions, making and wearing temporary artificial crowns. The second visit is for the crown. If more teeth are to be restored, it is advisable to make an appointment first.
