Single implant and crown
The most conservative replacement for one missing tooth: nothing is cut off the neighbouring teeth. Placement takes 45–90 minutes under local anaesthetic, followed by three to six months of healing before the crown is made.
An implant is a titanium screw placed into the jawbone; over three to six months the bone grows onto it, and a crown, bridge or full arch is then fixed on top. It replaces the root, which is why it does not depend on the teeth either side.
The deciding factors are how much bone there is, how good its quality is, the state of the gums, and how well any general condition is controlled.
Smoking is the single most useful thing to change: it roughly doubles the risk of an implant failing to integrate, and the effect follows how much is smoked. Uncontrolled diabetes affects healing in a similar way.
The number and position of implants is decided by the bone that exists and by how the bite loads it — not by how many teeth are missing.

For several missing teeth in a row, two or more implants carry a bridge, so the teeth at either end stay untouched. Fewer implants than teeth replaced — which is why the span has to be planned carefully, not extended to save one fixture.
A full arch fixed on four or six implants, with the rear ones tilted to use the bone that remains and often avoid grafting. A provisional bridge can usually be fitted within a few days; the final one waits for healing. Not everyone qualifies — bone volume, bite and lip support decide.
A CBCT scan measures bone height and width and shows where the nerve and the sinus sit. If the bone is thin, a graft or a sinus lift is planned first, which adds four to six months before implant placement.
Under local anaesthetic, 45–90 minutes for a single implant. Stability is recorded, and any temporary tooth or denture is adjusted so it does not load the implant while it heals.
Three to six months in which the implant is left alone. The lower jaw is usually ready sooner than the upper, and grafted sites take longer. Smoking and poorly controlled diabetes slow this stage down.
The gum is shaped around a healing abutment, then a scan or impression is taken and the crown or bridge is made — usually one to three weeks in the laboratory.
The restoration is screwed or cemented in place and the bite is checked. Hygiene visits every six months, with an x-ray at one year and then periodically: bone loss around an implant is silent until it is advanced.
Implant surgery is routine but it is still surgery into bone, and the failure modes are specific. These are the ones that matter.
An implant is not a tooth. It has no ligament, reduced feedback when you bite too hard, and once bone is lost around it, no way to grow it back. Hygiene and a night guard matter more than the brand on the box.
With local anaesthetic you feel pressure and vibration rather than pain. The first two days are bruised and swollen, and ordinary paracetamol or ibuprofen is usually enough; most people are back to desk work the next day.
Four to eight months from placement to final crown for a single implant, because the bone sets the timetable. A full arch on All-on-4 can have a fixed provisional within days, with the final bridge at four to six months.
Ideally not at all during treatment. Stopping at least a week before placement and for about eight weeks after measurably improves the odds of integration; smoking afterwards raises the long-term risk of bone loss around the implant.
Bone can be added — particulated graft with a membrane for width, a block graft for larger defects, or a sinus lift for the upper back jaw. It is a separate procedure with its own healing time, and it is planned from the scan rather than discovered during surgery.
A recent panoramic x-ray or CBCT, plus a note of which teeth are missing, is enough to say whether grafting is likely, roughly how many implants, and how long the plan would run.
General information, not medical advice. Suitability can only be judged after examining the mouth, reading a CBCT scan and reviewing the medical history; results vary between patients.
