All-On-4 dental implants are a permanent tooth replacement solution that uses four titanium posts surgically placed in the jawbone to support a full arch of prosthetic teeth, while dentures are removable prosthetic devices that sit on top of the gums. All-On-4 implants start from $25,000 per arch at our practice and function like natural teeth, whereas traditional dentures cost $2,000 to $5,000 per arch, are usually replaced every 5 to 8 years, and can slip or cause discomfort.
This page compares the two options in general terms. Which one suits you depends on your jawbone, your gum health, your medical history and your budget, and that can only be settled at an examination.
Key Takeaways
- All-On-4 implants are permanently fixed in your mouth; dentures are removable and must be taken out daily
- All-On-4 restores chewing function much closer to natural teeth than a removable denture does
- All-On-4 costs from $25,000 per arch upfront; dentures cost $2,000 to $5,000 but are usually replaced every 5 to 8 years
- All-On-4 transmits chewing forces into the jawbone, which helps preserve it; removable dentures rest on the gum and do not
- All-On-4 is cleaned like natural teeth; dentures require daily removal, soaking, and special cleaning
- All-On-4 has a well-established long-term track record in suitable, well-maintained patients
What Are All-On-4 Dental Implants?
All-On-4 dental implants are a full-arch tooth replacement system that uses four strategically positioned titanium implants per jaw. The implants are surgically inserted into the jawbone, two placed vertically at the front and two angled at the back to support a complete set of fixed prosthetic teeth.
The angled placement makes use of the bone you already have. It often removes the need for a separate bone grafting procedure.
Temporary teeth are attached on the same day as surgery in most cases. Patients can typically eat soft foods within the first few days. The titanium implants integrate with the jawbone through osseointegration over roughly 3 to 6 months.
Pros of All-On-4 Dental Implants
- Fixed permanently in your mouth, so there is no movement or slipping
- Restores chewing function much closer to natural teeth
- Transmits chewing forces into the jawbone, which helps preserve bone
- Cleaned like natural teeth with brushing and flossing
- Designed as a long-term restoration
- No palate coverage, which preserves taste and speech
- Most patients are able to return to a normal diet
Cons of All-On-4 Dental Implants
- Higher upfront cost: from $25,000 per arch
- Requires a surgical procedure, with several days of recovery
- Not suitable for patients with certain health conditions
- Limited insurance coverage (typically $1,000 to $3,000 annually)
- Requires sufficient bone height in the front of the jaw
- Smokers are asked to stop to give healing the best chance
- Active gum disease must be treated first
What Are Dentures?
Dentures are removable prosthetic devices designed to replace missing teeth and surrounding tissues. Traditional complete dentures consist of acrylic or porcelain teeth set in a gum-coloured plastic base that rests directly on the gums.
The upper denture covers the palate and relies on suction for retention. The lower denture is horseshoe-shaped to accommodate the tongue.
Dentures require daily removal for cleaning and maintenance. They sit on top of the gum tissue rather than being anchored in the jawbone, which means they can shift during eating or speaking. Many patients use denture adhesive to improve stability.
Pros of Traditional Dentures
- Lower upfront cost: $2,000 to $5,000 per arch
- Often attract higher health fund rebates than implants, though this varies by policy
- No surgical procedure required
- Available to patients who cannot have surgery
- Can be fitted relatively quickly
- No bone density requirements
- Restores facial structure and appearance
- Customisable to match desired tooth shade
Cons of Traditional Dentures
- Can slip or shift during eating and speaking
- Often need adhesive for stability
- Restore noticeably less biting force than fixed implants
- Do not stimulate the jawbone, so bone continues to resorb over time
- Require periodic adjustment as the jaw changes shape
- Need relines every 2 to 3 years at $300 to $500
- Hard, sticky and crunchy foods are usually difficult
- Daily removal and soaking required
- Usually replaced every 5 to 8 years
- Can chip or crack if dropped
- Palate coverage can affect taste perception
- Speech can take time to adjust to, particularly “s” and “f” sounds
- Can cause gum irritation, especially if the fit has loosened
How Do All-On-4 Implants Compare to Dentures?
| Feature | All-On-4 Dental Implants | Traditional Dentures |
| Stability | Fixed permanently; no movement | Can slip or shift; often needs adhesive |
| Jawbone preservation | Stimulates bone through chewing forces | Rests on gum; bone continues to resorb |
| Eating ability | Close to natural chewing function | Noticeably reduced; some foods difficult |
| Maintenance | Brush and floss like natural teeth | Daily removal and soaking required |
| Lifespan | Long-term restoration | Usually 5 to 8 years |
| Speech clarity | Natural speech; no palate coverage | May affect pronunciation initially |
| Cost (per arch) | From $25,000 | $2,000 to $5,000 |
| Surgery required | Yes | No |
| Suitability | Needs adequate bone and good general health | Available to almost everyone |
Cost Comparison: All-On-4 vs Dentures
All-On-4 dental implants start from $25,000 per arch at Radiant Smiles. This makes them significantly more expensive upfront than traditional dentures at $2,000 to $5,000 per arch.
The gap narrows over time. Dentures are usually replaced every 5 to 8 years and carry ongoing costs for adhesive, cleaning products, relines and adjustments. Implants carry lower ongoing costs but a much larger initial one. Which works out cheaper for you depends on your age, your health and how long the restoration needs to last, so it is worth asking for both figures in writing at your consultation.
Additional Costs to Consider
All-On-4 ongoing costs:
- Initial consultation and CT scans: $400 to $700
- Regular dental check-ups: $150 to $250 every 6 months
Denture ongoing costs:
- Denture adhesive: $15 to $30 monthly ($180 to $360 annually)
- Cleaning solutions: $10 to $20 monthly ($120 to $240 annually)
- Relines every 2 to 3 years: $300 to $500
- Adjustments: $100 to $200 per visit
Insurance Coverage
Private health insurance typically provides limited coverage for dental implants. Most policies offer $1,000 to $3,000 annually toward major dental work.
Dentures often receive higher rebates than implants, though the amount depends entirely on your policy and your annual limits. Check with your fund before committing to either option.
Many dental practices, including Radiant Smiles Dental Care, offer payment plans. These plans allow patients to spread the cost of All-On-4 treatment over 12 to 60 months.
Treatment Timeline Comparison
| Timeline Stage | All-On-4 Dental Implants | Traditional Dentures |
| Initial consultation | 1 to 2 weeks | 1 to 2 weeks |
| Tooth extraction healing | Same day as implant surgery | 8 to 12 weeks (if needed) |
| Fabrication time | 4 to 8 weeks before surgery | 2 to 4 weeks after healing |
| Surgery/fitting day | Temporary teeth same day | Multiple fitting appointments |
| Initial recovery | Several days of moderate soreness | Adjustment period of several weeks |
| Osseointegration | 3 to 6 months | N/A |
| Final restoration | Month 6 to 8 | Immediately after fitting |
| Total treatment time | 6 to 9 months | 4 to 6 months (with extractions) |
| Time without teeth | Temporary teeth fitted the same day | Potentially 8 to 12 weeks |
| Ongoing maintenance | 6-month check-ups | Adjustments every 6 to 12 months |
| Replacement needed | Prosthetic may be replaced in time | Every 5 to 8 years (complete) |
These timelines are typical for our patients. Yours may differ depending on extractions, healing and whether grafting is needed.
Comfort and Quality of Life
All-On-4 dental implants are fixed in place and do not cover the palate, so most patients find them more comfortable than a full upper denture. They require no adhesives and no daily removal.
Traditional dentures rest on the gum. They can move during eating or speaking, and a denture that has loosened as the jaw changes shape can rub and cause irritation. Regular relines and adjustments manage this.
Eating and Speaking Differences
Most All-On-4 patients return to eating normally, including foods that are difficult with a denture such as tough meats, crusty bread and raw vegetables. Denture wearers commonly find hard, sticky and crunchy foods the most difficult, and many adapt their diet around them.
For speech, All-On-4 implants preserve natural speech patterns immediately or within days. Dentures cover more of the mouth and can affect pronunciation while you adjust, particularly “s” and “f” sounds. For most people this settles with practice.
Patient Satisfaction
Patients who move from a loose denture to a fixed full-arch restoration commonly describe the biggest difference as confidence when eating and speaking in company. That is a consistent theme in what our own patients tell us, and you can read some of their accounts on our All-on-4 Perth page.
Success Rates and Longevity
Full-arch implant treatment has a well-established long-term track record. Success depends heavily on patient selection, surgical planning, and how well the restoration is maintained afterwards. Your dentist should give you a realistic assessment of your own prospects based on your bone, your gum health and your medical history, rather than a general figure.
Dentures do not have a comparable “success rate” because no surgery is involved. They are judged instead on fit, comfort and how well they hold up, all of which change as the jaw resorbs.
Factors Affecting All-On-4 Success
- Bone quality and volume. Adequate bone gives the implants stable support.
- Smoking. Smoking impairs healing and increases the risk of implant failure. Stopping before and after surgery matters.
- Oral hygiene. Implants can be lost to gum and bone infection around them if they are not cleaned properly.
- Diabetes control. Well-controlled diabetes is generally not a barrier; poorly controlled diabetes impairs healing.
- Regular reviews. Problems caught early are usually manageable.
Common Denture Problems
The most common problems are loosening fit as the jawbone resorbs, soft tissue irritation where the denture rubs, fungal infection if the denture is not cleaned and left out overnight, and breakage if a denture is dropped. All are manageable, but they mean dentures need ongoing care and periodic replacement rather than being a one-off treatment.
Long-Term Durability
All-On-4 implants are intended as a long-term restoration, and the titanium implants themselves can last many years. The prosthetic teeth attached to them wear and may need replacement in time, at a cost of $3,000 to $8,000 per arch.
Traditional dentures are usually replaced every 5 to 8 years, due to wear and to changes in jaw shape from bone resorption.
Which Option Is Right for You?
All-On-4 dental implants may suit you if you want a fixed solution, have sufficient jawbone density, can afford the higher initial investment, prioritise eating ability and comfort, and are in good enough general health for surgery.
Traditional dentures may suit you better if you have significant bone loss, need the most affordable immediate option, have health conditions that make surgery unwise, or simply prefer a non-surgical approach. A denture is a legitimate long-term choice, not a fallback.
Evaluation Factors
Your dentist will evaluate bone density through CT scans. They will assess gum health, review your overall health, and consider any medications that may affect treatment or healing.
Lifestyle factors matter too. These include dietary preferences, physical dexterity for cleaning, and what you want the result to look like.

Frequently Asked Questions
Can I convert my dentures to All-On-4 implants later?
Yes, you can transition from dentures to All-On-4 implants. However, bone loss from wearing dentures may mean bone grafting is needed first. This can add $2,000 to $5,000 per arch to the treatment cost. The sooner you transition to implants after tooth loss, the less grafting you are likely to need.
Will people know I have All-On-4 implants or dentures?
Modern All-On-4 prosthetics and quality dentures both look natural. All-On-4 implants are less likely to be noticed because they do not move during eating or speaking. Dentures may shift or click, which can reveal their presence.
How painful is All-On-4 surgery compared to getting dentures?
The procedure itself is done under local anaesthetic or sedation, so it is not painful at the time. Afterwards, expect several days of moderate soreness, managed with prescribed pain relief. Getting dentures is not surgical, but the adjustment period includes several weeks of gum soreness, excess saliva, and difficulty eating.
How do I clean All-On-4 implants vs dentures?
All-On-4 implants are cleaned like natural teeth, brushing twice daily and flossing or using interdental brushes around the prosthetic. Professional cleanings are recommended every 6 months. Dentures require daily removal, brushing with denture cleaner, overnight soaking in denture solution, and careful handling to prevent breakage.
