Denture
Discomfort

Dentures become loose primarily because of bone resorption — the gradual loss of jawbone volume that occurs when there are no tooth roots to stimulate the bone. After tooth loss, the jawbone begins to shrink, causing the ridge that supports the denture to change shape. Over years this also changes the facial profile, as the lower third of the face can appear shortened or collapsed. The ridge flattens, making the denture progressively harder to stabilise. This is one reason implant-supported solutions provide a more predictable long-term result — dental implants integrate with the bone and maintain stimulation.

All on 4 uses four implants per arch, with the two posterior implants angled to maximise contact with available bone. All on 6 uses six implants placed more vertically, distributing force across a wider area. The choice between them depends on the volume of bone remaining in the jaw and the load requirements of the restoration. Both provide a fixed, non-removable result. Your dentist in Southport will recommend the option best suited to your anatomy after imaging and assessment.

An implant-supported overdenture is a removable denture that clips onto two to four dental implants for retention. Unlike a conventional denture that relies on suction and gum contact, the implants hold the overdenture in place, preventing movement during function. The denture is still removed for cleaning. It provides improved stability compared to a conventional denture at a lower cost and complexity than All on X, and is a suitable middle-ground option for some patients.

Upper dentures benefit from suction across the palate, which provides natural retention. Lower dentures sit on a narrow ridge with the tongue and cheek muscles constantly working against them. The lower jaw also tends to lose bone volume faster after tooth loss. This combination means lower dentures are almost always less stable, which is why implant-supported solutions are particularly beneficial for the lower arch.

The cost of All on 4 dental implants on the Gold Coast varies depending on the complexity of the case, the materials used for the final prosthesis, and whether additional procedures such as bone grafting or extractions are required. At ArtSmiles Southport, we provide a detailed treatment plan and cost breakdown after the initial assessment so patients can make an informed decision. Payment plans and superannuation release options may also be available.

Implant-supported denture costs on the Gold Coast depend on the type of solution. An overdenture supported by two implants is typically the most affordable implant option. All on 4 or All on X fixed restorations, which are non-removable and provide greater stability, are a higher investment. At ArtSmiles Southport, we provide a detailed breakdown of costs after clinical assessment so you can compare your options with clarity. Payment plans and superannuation release may be available to help manage the investment.

Denture relining, adding material to the fitting surface to improve contact with the gum ridge, can temporarily improve the fit of a loose denture. However, relining addresses the symptom rather than the underlying cause. As bone continues to resorb, the denture will loosen again. Frequent relining requirements are a sign that the bone loss is progressing and that a more stable long-term solution may be appropriate.

Suitability for All on X depends on the volume and density of bone remaining in the jaw, overall gum and oral health, and general medical status. Many patients who have worn dentures for some time have experienced significant bone loss, but bone grafting or the use of tilted implants (used in All on X to avoid anatomical limitations) can make treatment possible even with reduced bone. An assessment including radiographic or cone beam CT imaging is necessary to determine individual suitability.

The All on X process typically involves an initial consultation and planning phase, implant placement surgery, a healing period during which a transitional prosthesis is worn (usually three to six months), and then placement of the definitive fixed restoration. The overall timeline from first appointment to final result is commonly six to twelve months depending on individual healing and any additional procedures required.

Yes. All on 4 and All on X dental implants replace a full arch of teeth with a fixed prosthesis that is secured to implants in the jawbone. Unlike conventional dentures, the result is not removable — it stays in place permanently and functions like natural teeth. This is the most stable long-term solution for patients who are tired of loose or uncomfortable dentures. Suitability depends on bone volume and overall health, which is assessed during a consultation.

The most affordable short-term option is denture relining, where material is added to the fitting surface to improve contact with the gum ridge. Denture adhesives can also temporarily improve stability. However, these are symptomatic fixes. For a longer-term solution at a lower cost than All on 4, an implant-supported overdenture using two to four implants can significantly improve denture stability. At ArtSmiles on the Gold Coast, we assess your situation and present options across different price points so you can choose what suits your needs and budget.
