What is it?
A dental implant is a screw-shaped part, usually made of titanium, that takes the place of the root of a missing tooth. It is placed in the jawbone and fuses with the bone during healing. A crown, bridge or denture is then made on top of the implant.
An implant can replace a single missing tooth, support a bridge where several teeth are missing, or support fixed or removable dentures in a jaw without teeth. Where all teeth are missing, in suitable cases a fixed prosthesis on a small number of implants may be planned.
Who may it suit?
- Adults with one or more missing teeth
- People unhappy with how well their removable denture stays in place
- People who do not want neighbouring teeth to be reduced for a bridge
Implant treatment requires enough bone volume in the jaw and general health that allows surgery. Uncontrolled diabetes, heavy smoking, radiotherapy to the head and neck, and some medicines for bone loss can affect the planning and outcome of treatment. If there is not enough bone, bone grafting can be done before or together with the implant. Implants are not placed in children and adolescents who are still growing.
How does the process work?
- Examination and imaging. Bone volume and nearby anatomical structures are assessed with an oral examination, a panoramic X-ray and a three-dimensional dental CT scan.
- Treatment plan. The number and position of implants and the type of prosthesis to be placed on them are decided.
- Preparation. If needed, treatment of decay, gums or extractions is completed and bone grafting is planned.
- Placing the implant. The implant is placed in the jawbone under local anaesthesia.
- Healing. Fusion of the implant with the bone usually takes a few months. A temporary tooth or denture can be used during this time. In some cases a temporary tooth can be fitted at the same visit.
- Restoration. An impression is taken and a crown, bridge or denture is made and fitted on the implant.
- Follow-up. The gum and bone around the implant are monitored with regular check-ups and cleaning.
Frequently asked questions
How long does implant treatment take?
It depends on the bone, whether bone grafting is needed and where the implant is placed in the jaw. The expected duration is explained to you when the treatment plan is made.
Will I feel pain during implant placement?
The procedure is done under local anaesthesia. There may be swelling and tenderness for the next few days; written advice is given for this period.
How long do implants last?
How long an implant stays in the mouth depends on oral hygiene, regular check-ups, smoking and general health. Inflammation similar to gum disease (peri-implantitis) can develop around an implant, which is why regular care is important.
Can I have an implant if I do not have enough bone?
When bone volume is insufficient, bone grafting or, in the upper jaw, a sinus lift can be carried out. Suitability is determined by a CT scan.
Whether it is suitable for you is determined by an examination.
