Dental implants are not really implanted with natural teeth, but implants shaped like tooth roots are surgically implanted in the alveolar bone of the missing tooth area, and after 3 months, when the artificial tooth roots (i.e., implants) fit into the alveolar bone, crowns are made on the artificial tooth roots. Dental implants have been recognized as the first choice for restoration of missing teeth by the dentistry community. Because the artificial teeth are deeply implanted in the alveolar bone, they can withstand the normal chewing force and are almost the same as natural teeth in function and aesthetics, therefore, they are called the third set of human teeth. The outstanding advantages of dental implants 1, strong function: can well restore the function of teeth, chewing function is greatly better than other traditional dentures. 2. No damage to neighboring teeth: Relying on its own artificial roots for restoration, it does not need to polish the healthy teeth next to it and does not cause any harm to the teeth. 3.Good retention: without the use of traditional retainers or braces, the artificial tooth root is closely integrated with the alveolar bone and rooted in the mouth like real teeth, with strong retention and stability. 4.Aesthetics: The crown can be made according to the face shape and the shape and color of other teeth of the patient to achieve the best effect of overall coordination and aesthetics. 5.Comfortable and convenient: without using the necessary rings of movable dentures, there is no foreign body feeling, which is very comfortable and convenient, and is conducive to keeping the oral hygiene. 6. Simple operation: Dental implant surgery is a small alveolar surgery, similar to tooth extraction, using local anesthesia, with little trauma, and can be eaten after surgery, almost painless. The implant placement procedure can be completed in a few minutes to an hour. Due to the use of titanium-based biomaterials that are highly compatible with the human body, dental implants do not cause any adverse side effects on the human body. If the osseointegration of the dental implant fails, i.e. the dental implant is not successful, it can be removed and reimplanted after the bone has healed, or other restorative methods can be used. The cost of dental implants includes the cost of the implant, the restorative abutment, the surgery and the crown. The average price of a dental implant is around 13,000-15,000 RMB, which includes the cost of the implant, abutment and surgery. There are many types of porcelain crowns that need to be placed on top of the implant after it has become viable. There are many types of porcelain crowns, and each person can choose according to his or her requirements and financial situation. If the implant is for a front tooth, it is recommended to use a better material of porcelain. It is recommended to use all-porcelain teeth (zirconia), whose entire teeth are made of imported porcelain powder and processed with a special process, they are more compatible with the human body and have a better aesthetic effect, especially to avoid the appearance of black lines in the gum area. Dental implants require a high level of skill, and the equipment and implant materials used are imported, so the cost of dental implants is relatively high, but they have significant advantages over other restorative methods, so it is worthwhile to invest in your health. Especially if the missing tooth is a single tooth, the cost of dental implants is not high compared to 3 porcelain teeth, and there is no damage to the adjacent teeth, which is the biggest advantage of dental implants. Problems to be noted after dental implant surgery: 1. Bite down on the gauze for half an hour and then spit it out, do not replace the gauze. 2, there will be a slight local swelling and pain after dental implantation, which is a normal reaction, you can use an ice pack to apply a cold compress; if the pain is heavy, you can take oral painkillers; if there is severe pain that cannot be tolerated, follow up promptly. 3, 2 hours after the implantation, you can eat and drink water, try not to eat too hot and hard food, and use the non-implant side to chew; if you use the implant side to chew, the implant screw may be loose and fall off, if this happens, please bring the lost screw to the follow-up appointment, and the doctor will re-tighten the screw. 4. Do not brush or rinse your teeth on the day of implantation, but brush your teeth carefully from the next day onwards, especially the implant screws exposed in the mouth, which need to be cleaned carefully to avoid the accumulation of food residues, and rinse your mouth with mouthwash. 5. 10 days after the implantation for follow-up and removal of stitches. 6.Patients with maxillary sinus lift need to use furosemide nasal drops and jessamine eye drops on the nasal cavity of the operated side, alternating between 2-3 hours for 5-7 days, and avoid blowing nose, puffing, sneezing, etc. 7. If the crown restoration is performed 3 months after the dental implant, please follow up promptly. If it is more than 6 months, there may be elongation of the opposite jaw teeth, which may lead to unrestorable. Dental implant care and maintenance 1. Dental implants are generally divided into 2 steps: first: implantation of artificial tooth roots; second: installation of fixed denture on the already stabilized artificial tooth roots. After the implantation of the artificial root, the temporary denture cannot be worn before the removal of the wires, and after the removal of the wires in 7-10 days, it will be decided whether it needs to be modified or not. 2. Within 3-6 months after the removal of the wires, pay attention to the protection of the artificial roots and do not chew hard with them to avoid loosening of the roots and affecting the newly formed bone around the roots, thus affecting the implantation effect, which is an extremely important issue to ensure the implantation effect. 3, after the implantation of the artificial root should pay attention to oral hygiene, after meals in time to rinse mouth, also can be used medicinal solution rinse mouth, every morning and evening should be soft bristle brush or cotton strip cleaning implant abutment surgery area once. 4. After the crown is installed, it should be gradually adapted to increase the hardness of chewing food. It is not advisable to chew anything too hard immediately to prevent impact by external forces. Once the impact may hurt the root of the tooth, immediately go to the hospital for examination and treatment. 5. Carefully execute the doctor’s prescription and return to the hospital for regular follow-up. Generally 1 month, 3 months, 6 months, 12 months when the follow-up. 6.After putting on porcelain teeth, pay attention to the hygiene of the area between the teeth and the neighboring teeth to prevent decay of the neighboring teeth. As long as the above points are done well, the implanted dentures can be used for a long time and give full play to its advantages in restoration, while the patient can also better improve the quality of life and achieve good teeth and appetite.
