What makes someone a good implant candidate?

Dental implant candidacy is determined by four factors, roughly in this order of importance:

1. Bone density and volume

A dental implant is a titanium post that is surgically placed into the jawbone. For the implant to integrate successfully (a process called osseointegration), there must be sufficient bone height, width, and density at the implant site. A CBCT (3D cone-beam CT) scan provides a precise measurement of your bone dimensions in all three planes – this is the most important diagnostic tool in implant planning.

Bone loss is common after a tooth has been missing for months or years, because the jawbone resorbs when it no longer has a tooth root to stimulate it. This does not automatically disqualify you – bone grafting can rebuild lost bone in many cases.

2. Gum and oral health

Active periodontal (gum) disease must be treated and stabilised before implant placement. Gum disease destroys the bone and soft tissue that the implant depends on. If you have a history of gum disease, your dentist will ensure it is in remission and that you are on a maintenance schedule before proceeding.

Untreated decay in other teeth should also be addressed first – a clean, healthy mouth gives the implant the best chance of long-term success.

3. General health and medical conditions

Most medical conditions do not prevent implant placement, but some require additional planning:

• Diabetes: Well-controlled diabetes (HbA1c under 8%) has minimal impact on implant success. Poorly controlled diabetes significantly increases infection and failure risk
• Bisphosphonate medications (for osteoporosis): These can affect bone healing. Inform your dentist of all medications – an implant may still be possible but timing and protocol may be adjusted
• Blood thinners: Usually manageable with your GP’s guidance – your dentist will liaise with your doctor about any adjustments before surgery
• Autoimmune conditions: Conditions on immunosuppressive therapy require careful assessment – healing may be slower
• Active cancer treatment: Implants are generally deferred until chemotherapy or radiation therapy is complete and the patient has recovered

4. Smoking

Smoking is the most significant controllable risk factor for implant failure. It reduces blood supply to the surgical site, impairs osseointegration, and increases the risk of peri-implantitis (infection around the implant). Studies show implant failure rates are roughly double in smokers compared to non-smokers.

Most implant dentists will still treat smokers but strongly recommend quitting or significantly reducing consumption before and after surgery. A minimum of 2 weeks smoke-free before surgery and 8 weeks after is the standard recommendation.

What about age?

There is no upper age limit for dental implants. Patients in their 70s and 80s regularly receive successful implants, provided their general health supports a minor surgical procedure. The implant assessment focuses on bone and health, not age.

The only age restriction is a lower limit: implants should not be placed until jaw growth is complete, which is typically around age 18 (sometimes later in males). For younger patients with missing teeth, a temporary solution (adhesive bridge or retainer with a false tooth) bridges the gap until implants can be placed.

The implant assessment – what to expect

An implant assessment at Pakenham Creek Family Dentist typically involves:

1. Clinical examination: Your dentist examines the gap, the condition of adjacent teeth, gum health, and your bite
2. CBCT scan: A 3D X-ray of the jaw that shows bone height, width, density, and the location of nerves and sinuses. This is the key diagnostic image for implant planning
3. Medical history review: Medications, chronic conditions, smoking status, previous surgeries
4. Treatment plan and options: If you are a candidate, the dentist presents the recommended approach – single implant, bridge on implants, All-on-X – along with any preliminary work needed (grafting, gum treatment, extractions)
5. Written quote: A detailed cost estimate including the implant, abutment, crown, any grafting, and any sedation

This assessment appointment takes approximately 30–45 minutes. There is no obligation to proceed.

What if I do not have enough bone?

Bone loss does not automatically rule out implants. Several grafting techniques can rebuild the jaw:

• Socket preservation: Bone graft material is placed into the tooth socket at the time of extraction to prevent the usual resorption. If you know a tooth will be extracted, ask about socket preservation – it can save you a separate grafting procedure later
• Lateral ridge augmentation: For ridges that are too narrow, bone graft material (synthetic, donor, or from your own jaw) is added to widen the ridge. Healing time: 4–6 months before implant placement
• Sinus lift: For upper back teeth where the sinus floor has dropped, bone material is added beneath the sinus membrane. This is a common and well-established procedure with high predictability
• Block bone graft: For significant bone loss, a block of bone is harvested from another part of your jaw (or a donor source) and fixed to the deficient area with screws. Used for more extensive rebuilding

Grafting adds $500–$2,000 to the total implant cost depending on the technique and extent. Your dentist will discuss this at the assessment and include it in the written quote.

Implant types and options

Single implant + crown

Replaces one missing tooth. The implant post integrates with the bone over 3–6 months, then a custom porcelain or zirconia crown is attached. This is the most common implant procedure. Cost: $4,500–$6,500 per tooth.

Implant-supported bridge

Replaces 3 or more adjacent missing teeth using 2 implants as anchors with a bridge spanning between them. More cost-effective than placing one implant per missing tooth.

All-on-X (full-arch rehabilitation)

Replaces all teeth in one jaw using 4–6 strategically placed implants that support a fixed full-arch prosthesis. Designed for patients who are edentulous (no remaining teeth) or whose remaining teeth are beyond saving. Cost: $25,000–$35,000+ per arch.

Implant-retained denture

A removable denture that snaps onto 2–4 implants for stability. More affordable than All-on-X, significantly more stable than a conventional denture. The denture is removed for cleaning but clicks securely into place during wear.

How much do dental implants cost in Pakenham?

• Single implant + crown: $4,500–$6,500 per tooth (without grafting)
• Bone grafting (if needed): $500–$2,000 additional
• Implant-supported bridge (3 teeth): $8,000–$14,000
• All-on-X full arch: $25,000–$35,000+ per arch
• Implant-retained denture: $8,000–$15,000 per arch (2–4 implants + denture)

Private health fund extras cover may contribute toward the crown component. Payment plans via Afterpay, Zip Pay, SuperCare, and NDP make larger treatments manageable. SuperCare allows you to access your superannuation for dental implant treatment under specific eligibility criteria.

Alternatives to dental implants

Implants are not the only option. Depending on your situation and budget, your dentist may discuss:

• Dental bridge: A false tooth anchored to adjacent natural teeth. No surgery, lower cost ($3,000–$5,000 for a 3-unit bridge), but requires reshaping of the neighbouring teeth and does not prevent bone loss at the missing-tooth site
• Partial denture: A removable appliance with replacement teeth. Most affordable option ($1,500–$3,500). Available in acrylic, flexible nylon, or chrome-cobalt. Requires daily removal for cleaning
• Full denture: For patients missing all teeth. Conventional (removable, rests on the gum) or implant-retained (snaps onto implants for stability)
• Do nothing: For a single missing back tooth that is not visible and does not affect chewing, monitoring without replacement is a valid option – though adjacent teeth may drift over time

Your dentist will explain the pros, cons, and long-term implications of each option at your assessment.
