Dental implants can cause damage, but both soft tissue and hard tissue damage are normal and recoverable injuries. The dental implant procedure, after cutting the gums and flaps, preparing the cavity on the alveolar bone in the missing tooth area step by step, finally screwing the implant in and suturing the gums, will cause some damage to the soft and hard tissues. Dental implant is a minimally invasive surgery, which is done with the least possible trauma. To reduce the trauma, saline can be used to cool down the hard tissues during the surgery to reduce the damage to the hard tissues and prevent bone burns, which can affect the osseointegration. Soft tissues can heal by regeneration of the epithelium and hard tissues will heal by a balance of osteoblasts and osteoclasts.
