Dental implants can be worn in two pieces, but the actual operation also depends on the specific situation. Generally a conventional implant can carry 1-2 dental implants. When the gap of the missing teeth location is too narrow to implant two implants at the same time, you can choose to wear two dental implant crowns; when three teeth are missing, you can implant two implants and wear three dental implant crowns. Therefore, dental implants need to be placed according to the location, number and range of missing teeth to choose the appropriate implant program. Maintain oral hygiene after dental implants and pay attention to the correct brushing posture. Avoid chewing food with dental implants for a short period of time, as this may cause resorption of the alveolar bone, which will eventually lead to loosening of the teeth. Smoking should also be avoided after dental implant surgery as it may cause oral inflammation and affect wound healing. It is recommended to follow the doctor’s instructions to choose the appropriate implant program, and if there is any discomfort after the dental implant, it is necessary to consult a doctor in time to deal with it.
