What Are All on 4 Dental Implants?

All on 4 Dental Implants offer a modern, effective solution for patients with significant tooth loss, providing a full-arch restoration using just four implants. At Cairns Dental Group, we use this advanced technique to help patients in Cairns regain the function and appearance of natural teeth without the need for removable dentures.


Unlike traditional methods that may require six or more implants per arch, All on 4 makes use of the available bone structure to avoid complex procedures like bone grafting. Two straight implants are placed at the front of the jaw and two angled implants at the back, providing strong, stable support.


In many cases, temporary teeth can be fitted on the same day as surgery, giving you an immediate transformation. The final result is a fixed, non-removable prosthetic that looks and feels like real teeth. This minimally invasive option can help restore confidence, comfort and long-term oral health with fewer procedures and faster recovery.

Key Treatment Benefits

This approach to full-arch tooth replacement can offer several functional and clinical advantages. The fixed design can improve the stability of the prosthesis, reducing the risk of movement during activities such as eating or speaking. For eligible patients, receiving a temporary prosthesis on the day of surgery may also support day-to-day function during the healing period.


By placing implants in areas of stronger bone, the procedure may eliminate the need for additional grafting. This can result in fewer appointments and reduced overall treatment time. The implant-supported structure can also assist in maintaining bone density in the jaw, which may help preserve facial structure over time.


Patients often report improved comfort and the ability to eat a wider range of foods compared to removable alternatives. When placed and maintained correctly, implant-supported prostheses can support long-term oral function, hygiene and quality of life under the guidance of a qualified dental practitioner.

Your Treatment Process

The All on 4 treatment process begins with a comprehensive consultation. During this visit, your dentist will assess your oral health, including the condition of your bone and gums. Diagnostic tools such as 3D imaging may be used to evaluate whether the procedure is suitable for your needs. A personalised treatment plan is then developed based on these findings.


On the day of surgery, four dental implants are placed into the jaw under local anaesthetic. Sedation options may be available depending on your individual case. In many situations, a temporary fixed prosthesis is attached on the same day to support function while the implants heal.



The healing phase typically takes between three and six months. During this time, the implants gradually integrate with the bone, a process known as osseointegration. Once healing is complete, the temporary arch is replaced with a custom-made permanent prosthesis that is adjusted for fit, comfort and appearance.

What Are the Disadvantages?

All on 4 dental implants may not be suitable for all patients, particularly those with insufficient bone or certain health conditions. The procedure involves surgery, which carries general risks such as infection or implant failure. Long-term maintenance is required, and repairs or adjustments may be needed. A comprehensive dental evaluation is necessary to assess individual risks and suitability.

Frequently Asked Questions

  • How long do All on 4 implants last?

    The lifespan of All on 4 dental implants can vary depending on factors such as oral hygiene, overall health, and ongoing maintenance. With proper care, implants may remain functional for many years. However, individual outcomes differ, and regular dental reviews are necessary to monitor the condition of the implants and prosthesis.

  • Are All on 4 implants painful?

    The surgical procedure is typically performed under local anaesthetic, and sedation may be offered where appropriate. Discomfort following surgery is common but usually manageable with prescribed or over-the-counter pain relief. Healing times vary, and patients should follow post-operative instructions closely to support recovery and reduce the risk of complications.

  • Can you eat normally with All on 4 implants?

    After the initial healing period, most patients are able to eat a wide variety of foods. However, during the early stages, a soft food diet is usually recommended to avoid putting stress on the implants. Long-term dietary habits may still require some caution to protect the prosthesis and underlying structures.

  • What is the difference between All on 4 and traditional implants?

    Traditional full-arch implant treatments often require six to eight implants and may involve bone grafting. All on 4 uses four implants strategically placed to maximise available bone, sometimes avoiding the need for grafting. Both methods aim to provide fixed tooth replacement, but suitability depends on individual clinical assessment.
