All-on-4 dental implants

Patients who no longer have natural teeth in the upper jaw, lower jaw or both arches.

Cases in which the remaining teeth cannot be retained predictably following clinical and radiographic assessment.

People who wear complete dentures and wish to consider a fixed alternative that is not removed by the patient.

In some patients, angled posterior implants can make better use of the available bone. However, this does not mean that bone grafting can always be avoided.

The treatment is designed to replace a complete dental arch rather than one or two isolated missing teeth.

Patients must be able to clean beneath the bridge, attend regular reviews and manage risk factors such as smoking, gum disease or tooth grinding.

Provides fixed teeth during healing and is designed to control functional forces while the implants integrate.

A soft or controlled-consistency diet helps avoid excessive loading of the provisional bridge and newly placed implants.

The bite, screw joints, soft tissues, hygiene and any movement, wear or fracture are checked during healing.

The final restoration is manufactured after implant integration using stable records of the healed gums, implant positions, bite and facial support.

The framework and restorative materials are selected according to prosthetic space, biting forces, appearance, repairability and the agreed treatment plan.

The final bridge requires professional reviews and may eventually need servicing, component replacement, repair or renewal.

Bone distribution, bite, bruxism, smoking, gum health, medical history and prosthetic requirements may make a different treatment design more appropriate.

Possible complications include swelling, bleeding, infection, altered sensation, injury to nearby anatomical structures or failure of an implant to integrate.

A complication affecting one implant may alter the support of the entire bridge and require unloading, repair or revision of the treatment plan.

The space between the bridge and the gums must be cleaned carefully to control plaque, inflammation and peri-implant disease.

Prosthetic teeth, frameworks, screws and other components can wear, loosen or fracture and may require maintenance, repair or replacement.

Advanced bone loss may require bone regeneration, a different number of implants or an alternative advanced implant technique.

Four implants support a fixed full-arch bridge. Immediate provisional teeth may be possible, while angled posterior implants can reduce the need for bone grafting in selected cases.

Some patients may benefit from five, six or more implants depending on bone distribution, bridge design, expected biting forces and contingency planning.

A removable full denture is stabilised by implants. The patient removes it for cleaning, and it may be appropriate when anatomy, hygiene access or cost favours a removable solution.

No implant surgery is required, but stability, chewing efficiency and comfort may be more limited, particularly when significant jawbone resorption is present.

Six implants do not automatically provide a better result, and four implants do not necessarily make treatment simpler. The decision must be justified by the anatomy and planned restoration.

Every implant-supported restoration requires daily cleaning, professional hygiene appointments, bite checks and periodic assessment of the implants and bridge.

A soft or controlled-consistency diet is normally advised during early healing to limit excessive forces on the implants and provisional bridge.

Hard, sticky or high-load foods should be reintroduced only in line with the clinical team’s instructions.

Depending on the design, cleaning may involve interdental brushes, implant floss or superfloss, a water flosser and other tailored aids.

Bleeding, swelling, a persistent unpleasant taste, discharge, pain or increasing movement should be assessed rather than ignored.

The screws, framework, prosthetic teeth, wear pattern and bite contacts require periodic examination.

Review frequency depends on plaque control, smoking, previous gum disease, bite, bruxism and other individual risk factors.

Your medical and dental history, existing reports, photographs and available scans can be reviewed to provide initial guidance and identify any further information required.

A clinical examination, 3D imaging, assessment of the gums and available bone, bite records and prosthetic planning are completed before treatment is confirmed.

The treatment schedule depends on any extractions required, implant stability, laboratory stages, healing and whether immediate loading is clinically appropriate.

The treatment plan should specify the expected length of stay, post-operative reviews, management of the provisional bridge and when further visits to Spain may be required.

International patients should understand whom to contact, how urgent complications will be managed and whether a dentist in their home country will participate in routine or emergency care.

Implants and fixed bridges require continuing professional reviews, hygiene appointments and bite checks after the patient returns home. This maintenance should be arranged before treatment begins.
