The anatomy of a dental implant – how it works, part by part

Understanding how an implant is built, and how it becomes anchored in bone, makes it far easier to weigh up whether it is right for you. A considered explanation from our practice at 295 King's Road.

In brief

  • Three components: fixture, abutment and crown
  • Anchored by bone over weeks to months
  • Planned with a 3D CBCT scan
  • Single implant and crown from £2,750
  • Written, itemised quote before treatment

Replacing the root as well as the tooth

When a tooth is lost, two things go: the visible crown and the root that anchored it. A denture or a conventional bridge replaces only the first. A dental implant replaces both, which is why it behaves so much like a natural tooth – and why the bone around it deserves so much attention during planning.

Each component, considered

The fixture

Dentists often call the post the "fixture". It is threaded, with a specially treated surface that encourages bone to attach, and its position is planned in advance from your 3D scan.

The abutment

The connection between fixture and crown. Its shape influences how the gum settles around the new tooth, which is especially relevant at the front of the mouth, where the gum line shows.

The crown

Crafted to match neighbouring teeth in shade, translucency and form, and designed around your bite as well as your smile.

Materials

Titanium and its alloys are the established choice for fixtures, valued for their strength and their compatibility with bone. Some systems use alternatives such as ceramics; whether one would suit you is a conversation for your consultation.

Osseointegration: how bone anchors an implant

After placement, the bone surrounding the fixture remodels and grows directly onto its surface. This biological bond, rather than any glue or cement, is what holds an implant steady. It develops gradually over weeks to months and cannot be hurried, which is why the definitive crown follows later. Where the gap would show, a temporary tooth is usually arranged in the meantime.

PlacementSmall gap around postWeeks laterNew bone moving inMonths laterBone hugs the threads

At placement a narrow space surrounds the fixture. Over the following weeks new bone fills it, and after some months bone lies directly against the threads, ready to support a crown. Illustration only.

There is a second reason bone matters. Without a root to stimulate it, the jawbone beneath a gap gradually resorbs. Because an implant transmits biting forces into the jaw, it helps to keep that bone in use, which can be relevant to the support of the lips and cheeks over time.

Myth or fact?

"An implant is simply a screw with a tooth on top." Partly true. There are three components, and the bond between bone and fixture is a living process that takes time.

"If you have been told you lack bone, implants are off the table." Not necessarily. Should additional bone be required, we explain the options, which may include grafting, and set this out in your written quote.

"Implants cannot develop gum problems." Myth. The tissue around an implant can become inflamed if plaque is left, so daily cleaning and regular reviews matter.

"Titanium is the only material used." Myth. It is by far the most familiar, but some systems use other materials.

Suitability, assessed individually

Gum health

Gum disease can affect healing and suitability. Where present, it is treated and stabilised before implants are considered.

Smoking

Smoking can influence how gum and bone tissues recover. We discuss it frankly and weigh it as part of your overall picture.

Medical history

Diabetes and certain other conditions can influence healing. Many people with well-controlled conditions remain candidates; each case is reviewed on its merits.

Bone and age

Implants are placed once the jaw has finished growing. Thereafter, the quantity and quality of bone shown on your scan matter more than age.

Who places your implant, and how it is planned

Implants at SW3 Dental are placed by Dr Antikleia Nalmpanti (Dr Anti), a general dentist with a special interest in implants, who visits our King's Road practice for implant cases. Every case is planned from a 3D CBCT scan, and placement is carried out under local anaesthetic; we do not offer sedation. Implants can replace a single tooth, secure a denture or support a full arch with All-on-4 (from £6,495 per arch). For a fuller picture of costs, see implant costs in Chelsea and our fees.

Common questions

How long does the whole process take?

Typically a few months from placement to final crown, mainly to allow osseointegration. Your plan sets out the expected sequence of visits at the outset.

Is the procedure uncomfortable?

Placement is carried out under local anaesthetic, so you should not feel pain during it. Some tenderness for a few days afterwards is normal. Sedation is not offered.

Will anyone be able to tell it is an implant?

Generally not. The crown is matched to your neighbouring teeth, and the abutment is shaped so the gum settles naturally around it.

What does an implant cost at SW3 Dental?

A consultation is £75, and a single implant with its crown starts from £2,750. You receive a written, itemised quote after your scan, and 0% finance through Tabeo is available, subject to status.

How should I care for an implant?

Much as you would a natural tooth: thorough brushing, cleaning between the teeth and regular examinations and hygiene appointments so the surrounding gum stays healthy.
