1. Impact
The harm of this kind of dental implants is mostly due to the pollution and complications of surgical instruments.
2. Gingival hyperplasia
Dental implants have poor local hygiene due to too little penetration of abutment or poor connection between abutment and bridge, and long-term chronic inflammatory stimulation can lead to gingival hyperplasia.
3. Numbness of lower lip
This is because the implantation technology is not in place and the nerve is damaged.
The injury of mandibular nerve can be recovered from the injury of dental implant. If the inferior alveolar nerve is damaged, the implant should be removed and replanted.
Final suggestion
It is really important to choose a professional stomatological hospital.
