Restoring Natural Form and Function: A Clinically-Led Guide to Dental Implants in London

Patients researching implants online encounter a strange mix of information. On one side, technical language about osseointegration and torque values. On the other, marketing that reduces a multi-stage surgical and prosthetic treatment to a single cheerful phrase about new teeth.

Neither is much help when you are trying to decide whether to proceed. What is more useful is understanding the sequence — what happens at each stage, why it happens in that order, and what a careful process looks like compared with a rushed one. Almost everything that determines the long-term result is decided before any surgery takes place.

This guide walks through that sequence. It is deliberately detailed, because the detail is where the difference lies, and it is honest about the points at which implant treatment is not the right answer.

Why replace a root rather than simply bridge the gap?

An implant differs from other tooth replacements because it restores the root as well as the crown. A conventional bridge spans a gap using the adjacent teeth as supports, which means preparing sound tooth structure and placing those teeth under additional load. A removable denture rests on the gum and transmits force to the mucosa rather than into bone. An implant is anchored within the bone itself, so force is transmitted directly into the jaw. That has two consequences: neighbouring teeth are left untouched, and the bone in the immediate area continues to receive the functional loading that helps maintain it. The trade-off is that it involves surgery, a healing period and a higher initial cost.

Every option has a place, and understanding the limitations of each is what makes the comparison meaningful.

Conventional bridges require the preparation of adjacent teeth. Where those teeth are already heavily restored, this may be reasonable. Where they are intact, it means removing healthy structure. Bridges also concentrate load on their abutments, and when one abutment develops decay or a fracture the whole restoration is affected — our article on implants where a bridge is failing covers what happens then.

Removable dentures do not require surgery and can restore a great deal of function, but they rest on tissue, need to be removed for cleaning, and do not slow the resorption of the ridge beneath them.

Resin-bonded (Maryland) bridges are considerably more conservative and are a good option in selected cases, particularly for a single front tooth in a young patient. See our page on Maryland bridges.

Doing nothing is also a decision with consequences: adjacent teeth drift, opposing teeth over-erupt, and the ridge resorbs. Our article on the long-term cost of not replacing missing teeth sets these out.

Osseointegration is a direct structural connection between living bone and the surface of a load-bearing implant. It is not glue and it is not a mechanical wedge — it is bone that has grown into direct contact with the titanium surface.

The process runs through recognisable stages. A blood clot forms at the interface. Inflammatory and progenitor cells arrive. Immature woven bone is deposited within the first weeks, then progressively remodelled into organised lamellar bone aligned to the direction of load. Mechanical strength increases substantially over this period.

Two clinical points follow from this. First, there is a window in the early weeks when the initial mechanical grip from surgery is decreasing while biological integration is not yet established — which is why the site is protected from load during that time. Second, the process is slower in soft bone and faster in dense bone. Our articles on implant healing time and on why bone quality matters more than bone quantity explore both points.

A thorough consultation covers considerably more than the gap itself:

• Full medical history, including all medications and any history of antiresorptive drugs, radiotherapy or immunosuppression.

• Smoking status, discussed honestly, because it materially affects outcomes.

• Full periodontal assessment. Untreated gum disease is a well-recognised risk factor for later problems around implants, and it is stabilised first. See our gum disease treatment page.

• Assessment of the remaining teeth, existing restorations and the bite.

• A discussion of what you actually want from treatment, which is not always what a brochure assumes.

Cone beam CT provides measurement of bone height and width, an indication of bone density, and the position of the inferior alveolar nerve, the mental foramen and the maxillary sinus. Two-dimensional radiographs cannot show width and cannot reliably show the relationship between a planned implant and these structures. Planning implant surgery without three-dimensional imaging is not appropriate in most sites.

The imaging is combined with a digital scan of the teeth and a plan for the final restoration. The implant position is then chosen to serve the prosthesis rather than the other way round — a principle sometimes described as restoratively driven planning. A surgical guide may be produced to transfer that plan accurately to the mouth.

You should receive a written treatment plan setting out the stages, the estimated timeline, the costs, the alternatives including the option of no treatment, and the risks. Time to consider it is part of proper consent, not a courtesy.

Before. Instructions on eating, medication and, where relevant, an antimicrobial rinse. Any temporary prosthesis is checked so that it does not press on the site.

During. Local anaesthetic; sedation is available where appropriate. The gum is reflected, the site prepared with a graded sequence of drills at controlled speed with irrigation to prevent heat damage, and the implant inserted. Stability is assessed at placement. Depending on the plan the site is either closed over or a healing abutment is fitted. Where an extraction is being done at the same visit, the gap between implant and socket wall is usually grafted — see our article on placement at the time of extraction.

After. Swelling typically peaks at around two to three days. Soft diet, no smoking, careful cleaning as instructed, and no loading of the site. Reviews follow.

Once integration is confirmed, the restorative phase begins.

An impression or digital scan records the implant position. The crown is then designed with attention to:

• Emergence profile — how the restoration emerges through the gum, which determines both the appearance and whether the tissue can be cleaned.

• Contact with adjacent teeth — too tight and floss shreds, too loose and food packs.

• Occlusion — because an implant has no periodontal ligament and therefore no physiological give, the bite is adjusted so that the implant is not overloaded, particularly during side-to-side movement.

• Material and shade — matched to the adjacent teeth, with attention to translucency and surface texture. Our article on natural aesthetics and translucency applies here too.

• Screw-retained or cemented — screw retention allows retrieval; cementation requires careful removal of excess cement, which is a recognised cause of inflammation if left behind.

An implant cannot decay, but the tissues around it can become inflamed and bone can be lost. Maintenance is not optional.

• Daily interdental cleaning around every implant, using the aids demonstrated. Our article on water flossers for implants covers useful adjuncts.

• Regular professional maintenance appointments with specific implant monitoring, including probing and periodic radiographs. Our dental hygiene page explains what these involve.

• A protective appliance if you grind — see night guards.

• Not smoking.

• Prompt reporting of bleeding, swelling, discomfort or any sensation of movement.

The NHS provides general information about dental implants at nhs.uk.

Arrange an assessment if:

• You have a missing tooth or a tooth of doubtful prognosis and want to plan before it is removed.

• An existing bridge or denture is failing.

• You have been told there is insufficient bone and would like a review with three-dimensional imaging.

• You have a medical condition or take medication that you have been told may affect implant treatment.

• An existing implant is uncomfortable, or the gum around it bleeds or is swollen.

• You want a written plan comparing implants with the alternatives, including doing nothing.

• An implant replaces the root as well as the crown, which is what distinguishes it from bridges and dentures.

• Bridges, dentures, resin-bonded bridges and no treatment all remain legitimate options in the right circumstances.

• Osseointegration takes months and passes through a phase of reduced stability in the early weeks.

• Three-dimensional imaging is essential for assessing bone width and locating the nerve and sinus.

• Planning should be driven by the intended final restoration, not by where an implant happens to fit.

• Gum disease must be stabilised before implants are placed.

• Crown design — emergence profile, contacts and occlusion — has a direct effect on long-term tissue health.

• Ongoing maintenance and not smoking are the two factors most within the patient's control.

The value in implant treatment comes from the planning rather than the placement. Imaging that shows what is actually there, a restoration designed before the implant is positioned, gums that are healthy before surgery begins, and a maintenance plan that continues afterwards — these are what separate a result that lasts from one that does not.
