1, bleeding

Mucoperitoneal exfoliation or extensive submucosal exfoliation has great damage, especially postoperative compression, which is prone to submucosal or subcutaneous bleeding. For example, submental congestion will also occur when the implant passes through the lower edge of the mandible in the first-stage operation. Local congestion can generally be absorbed in a few days, and it can be cold compress in the early stage and hot compress in the later stage after operation. Those who are prone to bleeding due to systemic factors should be treated symptomatically.

2, the lower lip is numb

Most of them are caused by mental nerve injury during intraoperative anatomy or direct trauma during implant implantation. The former can be recovered, and the latter should take out the implant to avoid nerve reduction and implantation.

3. The wound is cracked

Too tight or too loose suture, especially in the case of inducing infection, is more likely to lead to local wound dehiscence, and should be debrided and sutured in time to avoid implant exposure.

4. gingivitis

After implant denture restoration, dental plaque attached to the abutment will irritate the gums due to poor oral hygiene or improper cleaning methods. The formation of plaque is mainly due to the scratch of the surface smoothness of implant abutment, on which bacteria can multiply. Therefore, in addition to ensuring the smoothness of the abutment in the production and processing of the implant itself, the abutment surface should also be carefully protected during the surgical operation and self-care of the patient.

5, gingival hyperplasia

Long-term chronic inflammatory stimulation can cause gingival hyperplasia due to too little abutment penetration, or poor connection between abutment and bridge and poor local sanitary conditions.

6. Perforation of sinus mucosa

During maxillary implantation, due to insufficient bone mass, it is easy to penetrate maxillary sinus or nasal mucosa, which is bound to cause infection around the implant and should be taken out in time.

7. Influence

Infection is often caused by the pollution of operating area or surgical instruments and other complications.

8. Progressive marginal bone resorption

It mostly occurs in the bone tissue of the implant neck, which is related to gingivitis, inflammation around the implant, excessive stress of the implant and long-term failure to correct the mechanical fracture of the implant.

9. Implant trauma

This is one of the serious shortcomings of dental implants. Common implant dentures are accidentally hit, which will cause the implant to loosen slightly in serious cases.

10, mechanical fracture of implant

The fracture of the part connected with the implant, such as the central screw and the bridge post screw, is mainly due to mechanical factors or unreasonable stress distribution.
