The risk of implant surgery
Most of the implants are placed in local anaesthesia, thus with a decent medical history most of the advers reactions, regarding local anaesthetics can be avoided.
When placing the implants it is theoretically possible to injure neighbouring structures like the inferior dental nerve, the sinus cavity, neighbouring roots. With the right technique and planning these risks are usually minimal.
Implant rejections are relatively low in approximatelly 2% of the cases.
The secret of longterm implant survival is the right planning and regular check ups, good oral hygiene.
