Dental implants: how they work, placement and recovery

What is a dental implant?

An artificial root made of titanium

A dental implant takes the place of the root of a lost tooth: a titanium screw is set into the upper or lower jawbone, where that root used to sit. It becomes the anchor point for a crown, a bridge or a full prosthesis. Titanium is chosen for a property few materials share: living bone lays itself down directly on its surface and locks onto it, a process called osseointegration. The final restoration is only fitted once that bond has formed, which spreads the treatment over several months.

The reconstruction has three separate parts. In the bone, the implant takes over the mechanical job of the missing root. Above the gum, an abutment bridges the gap to the visible part. The crown, the bridge or the denture then forms the tooth, or the group of teeth, that you see and chew with. Those three parts are designed together: an anchor that has integrated perfectly under a poorly fitted crown, or careful ceramic work on an anchor that is too short, both leave you with a disappointing result.

Placement is dental surgery and falls exclusively to an oral surgeon or to a dentist who specialises in implantology. The procedure involves bone, nerve and sometimes the sinus, and the treatment plan has to account for the remaining teeth, the state of the gums and the bone actually available. A practitioner trained in implantology also judges whether the site can take an implant straight away, or whether an extraction, a graft or a sinus lift has to come first.

What losing a tooth leads to

A gap left in the arch changes over time. Chewing shifts to the side that still has teeth, which tires those teeth and makes some foods hard to bite through. Speech shifts too, because the tongue and the airflow press against the teeth to shape part of our sounds: a gap at the front is often heard before it is seen.

The gap then unsettles the whole dentition. The teeth on either side gradually tip into the free space, and the opposing tooth, the one in the other arch, drifts down for want of contact. These movements are slow, which gives the impression that nothing is happening while the bite comes apart month after month. Replacing the missing tooth therefore protects the teeth still in place as much as the function that has been lost. Those migrations also weigh on the replacement itself: a tilted neighbouring tooth narrows the space for the prosthesis and an over-erupted opposing tooth reduces the height available, so an old gap sometimes calls for a period of preparation before it can take an implant.

When the missing tooth sits at the front of the mouth, the cosmetic loss adds to these mechanical effects: the gap shows when you speak, when you smile and in photographs. In that area people ask for a replacement sooner, because the social discomfort comes before the chewing problem. Further back, it is function that raises the alarm, sometimes after the neighbouring teeth have already begun to move.

What an implant changes day to day

Compared with a traditional removable denture, an implant and its restoration give you something durable and comfortable that looks close to natural. A removable denture rests on the gum tissue and, often, on clasps or a plate; it comes out at night and for cleaning. Once osseointegrated, the implant stays put, and the rebuilt tooth is looked after like a natural one, with brushing and interdental cleaning.

That stability also changes how patients feel. Many describe, with a removable denture, the worry that it might come loose while they are talking or eating, and an anchor in bone takes that doubt away. An implant is still a device, though: it has no ligament, and the tissues around it need hygiene that is as rigorous as for natural teeth, if not more so.

Functionally, a well integrated implant allows efficient chewing and natural speech. The chewing load passes into the bone, which keeps it stimulated. A missing tooth, by contrast, leaves the alveolar bone unloaded, and that volume tends to shrink over time. This is one of the reasons a replacement put off for years then calls for a bone graft, a sinus lift or a shorter implant.

The lifespan you can expect comes from that integration. Depending on the patient’s age, an implant can last a lifetime, with no fixed replacement interval, where a removable denture wears out and has to be remade. Maintenance is the condition for that lifespan, and the crown, a separate part exposed to wear and knocks, follows its own review schedule.

What 10-year and 20-year follow-ups show

Clinical follow-up puts figures on that lifespan. Howe, Keys and Richards pooled 18 prospective studies on implant survival at 10 years. The survival rate comes out at 96.4% (95% confidence interval: 95.2 to 97.5). When the sensitivity analysis includes patients lost to follow-up, the figure drops to 93.2%. Both readings describe the same body of data: the first counts the implants still seen at check-ups, the second estimates what became of the records whose trail goes cold. Either way, more than nine implants in ten are still working at ten years.

Those two numbers are read alongside their method. The 95% confidence interval gives the range the true rate most likely falls within, given the size of the samples pooled, here between 95.2 and 97.5. The sensitivity analysis recalculates survival by including the records that dropped out of follow-up, whose outcome is unknown, and that more cautious calculation brings the rate down to 93.2%. The first figure reports what was observed, the second what incomplete observation may cost.

The same work flags a point about age: the risk of losing an implant is possibly doubled after 65. That factor goes into the assessment alongside smoking or gum disease, at the point where the treatment plan is discussed. In a younger patient, with favourable bone and good hygiene, keeping an implant for life remains a realistic prospect; after 65, the conversation takes this possible increase in risk into account.

Over a longer horizon, Kupka and colleagues ran a 20-year meta-analysis. Mean implant survival reaches 92% in prospective studies, 78% once patients lost to follow-up are imputed, and 88% in retrospective studies, so roughly 4 implants in 5 are still working at twenty years. The gap between 92% and 78% measures what the statistical handling of incomplete records does to the same finding: most implants followed for two decades stay in place. The causes of failure are described there as multifactorial, which matches day-to-day practice, where bone, infection, overload, smoking and hygiene weigh together rather than separately.

The visible part has follow-up data of its own. Pjetursson, Sailer, Latyshev and their co-authors analysed 49 trials and prospective studies, covering 57 cohorts, on all-ceramic single crowns on implants, whether layered or monolithic. Survival of those crowns at 3 years ranges from 96 to 97.6% depending on the ceramic material. That rate measures how the ceramic restoration holds up, which is separate from the anchor beneath it: a cracked, worn or debonded crown is usually repaired or replaced on an implant that has stayed healthy, and a stable implant still needs its prosthesis watched. Follow-up therefore runs on two levels, bone and prosthesis, as the dental crowns guide also sets out.

How long osseointegration takes

Between placing the implant and fitting the final prosthesis, 3 to 6 months are needed for the bone to bond to the titanium surface. Over those weeks the bone reorganises itself against the implant, and loading it definitively too early would expose the anchor to micromovement at the very moment that bond is forming. The timetable your practitioner gives you follows from this biology: it varies with the site, the bone quality and any preparatory stages.

The full treatment, first examination through to the final crown or bridge, therefore runs over several months. That biological delay is the same in the UK and abroad. What varies from one centre to another is how long you wait for a chair and for the dental laboratory, depending on the diary the centre is working with.

From assessment to treatment plan

Three things decide whether it can be done: the remaining teeth, the state of the gums and the volume of bone in the jaw. Inflamed gums or untreated periodontitis weaken the future margin around the implant, where inflammation then reaches the supporting bone. Bone that is too thin or too shallow does not give a standard-length implant the envelope it needs. Teeth that are beyond saving and still in place occupy the site and will have to come out before it. From that examination comes a treatment plan tailored to you, with a timetable for each stage.

When the site is not ready, a preparatory phase is added, with an extraction, a bone graft or a sinus lift depending on the deficit found. A graft rebuilds height or width. A sinus lift, at the back of the upper jaw, raises the sinus floor to recreate bone beneath that cavity. These preparatory stages lengthen the process, because the graft or the newly formed bone consolidates before it can take the implant, unless the protocol chosen allows both to be done in the same session.

Placement itself is carried out under local anaesthetic. The diameter and length chosen, the depth of burial and the angulation follow from the bone volume measured at the assessment and from how the site relates to the inferior alveolar nerve in the lower jaw or the sinus floor in the upper jaw. The last stage fits the restoration chosen, a single crown, a bridge on several implants, a full screw-retained bridge or a clip-on removable denture, once the anchor is judged stable.

Implant lengths and prostheses: what decides the choice

The length chosen follows the height of usable bone above the nerve or below the sinus. Two anatomical limits frame that choice: in the lower jaw, the inferior alveolar nerve, which the implant must keep clear of; at the back of the upper jaw, the sinus floor, which lowers the usable height. Ridge width counts as much as height, since bone that is too thin will not wrap around the implant on all sides. Intact bone takes an implant of ordinary size; a resorbed ridge points towards a shorter implant, which sometimes saves a graft; severe atrophy of the upper jaw leads to looking for the anchor outside the jaw, in the cheekbone. Each format is set out further down, and the zygomatic implants guide covers the particular case of malar anchorage.

The prosthesis answers to other criteria: how many teeth are missing, where they sit on the arch and what the patient can clean every day. A single missing tooth calls for a single restoration. Several gaps next to each other are treated in one piece, which cuts the number of anchors needed. A whole arch is rebuilt on a small number of implants spread across it, fixed or clip-on depending on the patient’s dexterity and hygiene. That last criterion counts for more than you might think: a fixed reconstruction is cleaned in place, around abutments that are sometimes hard to reach, whereas a clip-on denture comes out to be brushed away from the mouth. The All-on-4 protocol is described in the All-on-4 dental implants guide.
