Dental implants are osseointegrated synthetic roots.
They can be used to replace one or several teeth, or all of the teeth.
The implants are then used as support for a fixed cosmetic prosthesis (crown or bridge) or to stabilise dentures.
After a pre-implant consultation, a panoramic x ray and an in-surgery scan, the dental implants are fixed into place under local anaesthetic in a dedicated room.
The permanent fixed prosthesis (crown or bridge) will be attached to the implant three to six months later, in the meantime a temporary prosthetic will be worn.
Dental implants are a reliable solution with a 90 % success rate over the past 20 years.
Dental implants are a lasting solution which allow healthy teeth and maximal stable bone tissue to be preserved.
Dental implants provide a fixed prosthesis for all ages with a cosmetically pleasing and comfortable result.
Dental implants carry some contraindications.

4. Complications of dental implants:
As with any surgical procedure, the placement of a dental implant may cause complications. The following complications are rare but can occur:
– anesthetic risk
– no osseointegration of the implant
– infections
– nerve damage
– hemorrhage
