What a dental implant actually is

People use the word implant for the whole thing. It is three parts, fitted at separate appointments.

The fixture, or implant body
A threaded titanium post, roughly the size of the root it replaces, placed in the jawbone. This is the part that fuses with bone, which is why treatment takes months.
The abutment
The connector that fastens into the fixture and passes through the gum, fitted once the implant has integrated. Its shape decides how the gum drapes around the crown.
The crown, bridge or attachment
The part you see and chew with. One implant carries one crown, and two or more can carry a bridge.
Osseointegration
Bone cells grow onto the microscopic texture of the titanium until the fixture is locked into the jaw. Not glue, and not a screw in wood, but living bone bonding to a surface. It takes around three to six months.
Implant-retained overdenture
A lower denture that will not stay put can clip onto two or more implants and stop lifting when you chew. See dentures and partials and fixed bridges.

What decides whether an implant will work for you

Implants do well in the right mouth. Most of the assessment is whether the site and the patient can support one.

  • Bone volume and quality. There has to be enough height and width in the right place. The nerve to the lip limits depth in the lower jaw and the sinus sits low in the upper, so imaging comes first. A graft can rebuild a shrunken ridge.
  • Gum health. Active gum disease is treated first, because the same bacteria cause trouble around implants.
  • Smoking and general health. Smoking impairs healing in gum and bone and raises the failure rate, and poorly controlled diabetes slows healing. Neither rules treatment out, but both change the odds.
  • Medications and past treatment. Bisphosphonates and other antiresorptive drugs, for osteoporosis or cancer care, change how the jaw heals, and a low dose tablet is different from high dose intravenous treatment. Radiotherapy to the jaws also alters healing. Bring names and doses.

Extensive grafting, sinus procedures and complicated medical histories are referred to a specialist. Get in touch and we will say which applies.

How implant treatment runs, start to finish

The usual sequence for a single missing tooth.

  1. Assessment and planning

    Examination, x-rays and three dimensional imaging where the site needs it, then a written plan with fees and the alternatives, including a bridge, a partial denture and doing nothing.

  2. Extraction and grafting, if needed

    If the tooth is still there it comes out first, often with graft material in the socket to hold the ridge.

  3. Placing the implant

    The surgical phase, under local anesthetic in the office. A small opening in the gum, a precise channel prepared in the bone, the fixture placed and covered with a healing cap. A single implant takes an hour.

  4. Healing, then the crown

    Integration takes months, with nothing to do but keep the area clean, and a temporary tooth can be arranged if the gap shows. An impression then records the implant position, the abutment goes on, and the crown is made and shade matched, with the bite adjusted so it is not overloaded.

Dental implant compared with a fixed bridge

For one missing tooth with a natural tooth on each side, the neighbors usually settle it.

Consideration Single implant and crown Three-unit fixed bridge
Neighboring teeth Untouched. Nothing is cut down. Both are prepared for crowns. If they already carry large fillings that is no loss. If they are intact, it is.
Time and surgery Months, most of it healing, and minor surgery under local anesthetic. Two or three visits over a few weeks, and no surgery.
Bone and cleaning The implant loads the bone, so the ridge keeps its shape. Cleaned much as a tooth is. The ridge shrinks under the false tooth, and floss must be threaded underneath daily.
If it fails later The implant can often be removed, the site regrafted and treatment retried. Decay or a fracture in a supporting tooth takes the whole bridge.

Dental implant questions

Does getting a dental implant hurt?

Placement is done under local anesthetic, so you feel pressure rather than pain. The site is smaller than the socket left by an extraction, and most people manage afterwards with an over-the-counter anti-inflammatory and swelling for two or three days.

How long does the whole process take?

For a straightforward site with good bone, three to six months from placement to the finished crown, most of it healing with no appointments. If a tooth has to come out first, or the ridge needs grafting, add a few months.

What does a dental implant cost?

The fee has separate parts: the surgical placement, the abutment and the crown, with grafting billed separately. That is why one quoted number is rarely comparable between offices. You get an itemized estimate first. See insurance and financing.

Can an implant fail?

Yes. Early failure means it never integrates, which shows in the first months and means removing it, letting the site heal and trying again. Late failure is nearly always infection or overload. Implants do very well over ten years and beyond in suitable, well maintained patients, but nobody can promise an outcome.
