You’ve been told you don’t have enough bone for a dental implant — and now you have a decision to make. The traditional path is bone grafting, which can add months of healing and a second surgical site. The other path is subperiosteal implants, a niche option that most general practices don’t offer. At Palm Beach Dental on the Gold Coast, this is something the team has been providing for years, supported by onsite 3D X-ray (CBCT) for precise planning and a treatment room that can complete the case without external referrals.
Why do some patients not have enough bone for dental implants?
Patients most often run out of bone for dental implants because of long-term tooth loss, advanced gum (periodontal) disease, trauma, osteoporosis, or simply the natural reduction in jawbone that happens after teeth are removed. Better Health Channel notes that conventional dental implants rely on sufficient jawbone volume and density for osseointegration (the bone fusing to the implant) to occur. Once a tooth is lost, the surrounding bone begins to resorb, and the longer the gap has been there, the more bone has been lost. By the time a patient considers implants years later, the ridge may be too narrow or too short to hold a conventional implant without augmentation.
How does a dentist assess if there is enough bone for an implant?
A dentist assesses bone for an implant with a clinical exam, dental study models and 3D imaging (CBCT) that measures bone height, width, density and proximity to nerves and sinuses in millimetres. The Australian Dental Association recognises cone-beam computed tomography (CBCT) as the standard of care for 3D imaging in implant planning, and Palm Beach Dental has this technology onsite, so patients do not have to travel to a radiology centre for a scan. The 3D image lets the dentist measure the exact bone available, plan the implant position digitally, and identify whether a conventional implant, a graft, or a subperiosteal framework is the most appropriate solution. The principal dentist, Dr Jijesh Nhalila-Valappil, has additional training in dental implants and oversees the practice’s implant planning workflow.
What is bone grafting and when is it needed?
Bone grafting is a surgical procedure that adds bone (or a bone-substitute material) to the jaw to increase its volume and density, and it is needed when there is not enough native bone to anchor a conventional dental implant. The graft may be taken from another part of the patient’s jaw (autograft), sourced from a donor bank (allograft), or made from synthetic material. It is a well-established procedure, but it does add months of healing before an implant can be placed, and it carries its own surgical risks and costs. The National Institute of Dental and Craniofacial Research notes that for some patients, the extended timeline and additional surgery make grafting a poor fit, which is exactly the gap that subperiosteal implants were designed to fill.
What are subperiosteal implants and how do they avoid bone grafts?
Subperiosteal implants are custom-designed metal frameworks that sit on top of the jawbone but under the gum, anchored in place with small screws, and they avoid bone grafts because they do not need to be embedded deep into the bone. Healthdirect Australia describes them as a long-standing alternative for patients with insufficient jawbone to support conventional endosteal implants. At Palm Beach Dental, the framework is designed from a CBCT scan of the patient’s exact jaw anatomy and fabricated from biocompatible titanium, which integrates with the overlying gum and bone surface. Because the framework rests on the bone rather than inside it, no grafting is required — a major differentiator for patients who have been told they are “not implant candidates” or who want to avoid a second surgical site.
| Feature | Conventional (endosteal) implant | Bone graft + conventional implant | Subperiosteal implant |
|---|---|---|---|
| Anchored in | Inside the jawbone | Inside the jawbone (after graft heals) | On top of the jawbone, under the gum |
| Need for bone graft | Sometimes | Always | No |
| Number of surgical sites | 1 | 2 (graft + implant) | 1 |
| Total treatment time | Shorter | Often 6-12 months longer | Comparable to a conventional implant |
| Suitable for low bone | No | After graft heals | Yes |
| Available at Palm Beach Dental | Yes | Yes | Yes (niche offering) |
Who is a good candidate for subperiosteal implants in Palm Beach?
A good candidate for subperiosteal implants is a patient with insufficient jawbone for a conventional implant who wants to avoid bone grafting, has reasonable general health, does not smoke heavily, and has healthy gums or gum disease that is well controlled. They are also a good option for long-term denture wearers whose ridges have resorbed significantly, and for patients who have been told previously that they are not candidates for conventional implants. The team at Palm Beach Dental assesses candidacy through a comprehensive implant consultation, including a full medical and dental history, a clinical exam, and a CBCT scan to map the jaw in 3D. Patients with uncontrolled gum disease, heavy smoking, or certain systemic health conditions may need additional management before implant treatment is planned.
How much do subperiosteal implants cost compared to bone grafting?
Subperiosteal implants at Palm Beach Dental are quoted per case, while bone grafting adds the cost of the graft procedure plus a second surgical appointment to the conventional implant fee. The practice publishes transparent implant pricing online: a single implant and crown is $3,999, a 4-implant bridge is $9,999, and an All-on-4 / All-on-X arch is $15,999. Because subperiosteal treatment is case-specific (every framework is custom), the fee depends on the number of teeth being replaced, the complexity of the framework and whether single-tooth or full-arch restoration is planned. The advantage of avoiding a bone graft is not just financial — it removes the need for a second surgery, an additional 4 to 6 months of healing, and the discomfort of a donor site. Afterpay, the National Dental Plan (Humm) and early release of superannuation (for eligible essential treatment) are all available to help manage the investment.
What is recovery like for subperiosteal implants?
Recovery from subperiosteal implants is similar to recovery from a conventional implant — a few days of rest, soft foods, and careful cleaning around the surgical site — with most patients returning to normal activities within 48 to 72 hours. Because there is no bone graft, there is no second donor site to heal. The first phase is osseointegration of the framework to the bone surface, which the practice monitors over several months. Once integration is complete, the abutments and final crowns, bridges or dentures are attached. The team at Palm Beach Dental provides a clear written aftercare plan covering pain management, eating, oral hygiene and review appointments, and remains contactable for any concerns during recovery. As with any surgical procedure, individual recovery varies, and the practice’s standard disclaimer applies.
Frequently asked questions
Are subperiosteal implants safe? Yes. Subperiosteal implants have a long clinical history, are made from biocompatible titanium, and are placed by trained implant clinicians. The main risks — infection, framework failure, or damage to surrounding tissue — are uncommon and managed with careful planning and aftercare.
How long do subperiosteal implants last? With good oral hygiene and regular dental visits, subperiosteal implants can last 20 years or more, in line with conventional implant longevity.
Will my health fund cover subperiosteal implants? Coverage varies by fund and policy. The team at Palm Beach Dental can help you check your entitlements and process rebates onsite.
Can I have a full arch of teeth on subperiosteal implants? Yes. Subperiosteal frameworks can support a single crown, a multi-tooth bridge, or a full arch of teeth depending on the patient’s needs and the anatomy of the jaw.
Where is the practice located? Palm Beach Dental is at 1142 Gold Coast Highway, Palm Beach, QLD, with off-street parking from Palm Beach Avenue or Sixth Avenue. The team also welcomes neighbouring Currumbin patients, Elanora locals and West Burleigh families.
