Dental Implants vs Dentures: Which Is the Better Option in Melbourne?
If you are missing teeth and weighing up your replacement options, the choice usually comes down to dental implants, conventional dentures, or a hybrid of the two. Each option sits at a different price point, and each comes with trade-offs in comfort, function, bone health, and longevity. At Pakenham Creek Family Dentist, we place Straumann implants exclusively and also fit conventional and implant-retained dentures, so we see the full range of outcomes. This guide compares all three options honestly so you can make an informed decision.
The short answer
Dental implants are the best long-term replacement for missing teeth. They preserve bone, feel natural, and can last 25 years or more. A single implant costs $4,500 to $6,500. Conventional dentures are the most affordable upfront ($1,200 to $3,500 per arch) but accelerate bone loss and need replacing every 5 to 10 years. Implant-retained dentures are the middle ground at $8,000 to $15,000 per arch: a removable denture that clips onto implants for vastly improved stability. Full-arch All-on-4 implant treatment costs $25,000 to $35,000 per arch and delivers a fixed, permanent set of teeth.
The three options explained
Before comparing costs and outcomes, it helps to understand what each option actually involves.
Conventional dentures
A conventional denture is a removable acrylic plate with prosthetic teeth attached. It sits on your gums and is held in place by suction (for a full upper denture), by clasping onto remaining teeth (for a partial denture), or by denture adhesive. No surgery is required. Impressions are taken, the denture is fabricated in a dental laboratory over several appointments, and adjustments are made until the fit is acceptable. Conventional dentures replace the visible part of the teeth but do nothing for the bone underneath.
Dental implants
A dental implant is a small titanium-zirconium post that is surgically placed into the jaw bone, where it fuses with the bone over 8 to 12 weeks through a process called osseointegration. Once integrated, a custom crown, bridge, or full-arch prosthesis is attached to the implant. The implant replaces the tooth root, not just the visible crown, which means it transfers chewing forces into the bone the same way a natural tooth does. At Pakenham Creek Family Dentist, we use Straumann implants because of their 99.6% ten-year survival rate and patented SLActive surface technology.
Implant-retained dentures
An implant-retained denture (also called an overdenture or snap-on denture) combines elements of both. Two to four dental implants are placed in the jaw, and a modified denture clips onto them via locator attachments or a metal bar. The denture is still removable for cleaning but is anchored securely during the day. This option gives patients who cannot afford full fixed implant treatment a significant upgrade in stability, chewing power, and confidence compared to conventional dentures.
Cost comparison
The table below shows the typical cost range for each option at Pakenham Creek Family Dentist. All prices are per arch (upper or lower) unless otherwise stated.
Full conventional denture: $1,200 to $3,500 per arch
A standard acrylic full denture sits at the lower end. A premium denture with higher-grade teeth, a chrome cobalt metal frame (for partial dentures), or a flexible base material sits at the upper end. Relines ($200 to $400) are needed every 2 to 3 years, and a complete replacement every 5 to 10 years. Over 20 years, the cumulative cost of conventional dentures, including relines and replacements, typically reaches $6,000 to $14,000 per arch.
Single dental implant with crown: $4,500 to $6,500
This replaces one missing tooth with a Straumann implant, abutment, and porcelain or zirconia crown. The implant post can last a lifetime, and the crown typically lasts 15 to 20 years before needing replacement. Over 20 years, the cost of a single implant is essentially the original fee plus potentially one crown replacement ($1,200 to $1,800), totalling $4,500 to $8,300.
Implant-retained denture: $8,000 to $15,000 per arch
This includes two to four Straumann implants, locator abutments, and a new denture modified to clip onto them. The denture component still needs relining or replacement over time (every 7 to 10 years), but the implants themselves are permanent. The cost variation depends on whether two or four implants are placed and the quality of the denture prosthesis.
All-on-4 fixed implant bridge: $25,000 to $35,000 per arch
Four Straumann implants support a permanent fixed bridge that does not come out. This is the closest replacement to natural teeth in terms of function and feel. The bridge material drives the price range: acrylic composite at the lower end, zirconia at the upper end. Over 20 years, the main additional cost is bridge refurbishment or replacement, which is typically needed once in that timeframe.
Bone preservation: the critical difference
This is where the comparison becomes most significant for long-term health. When a tooth is lost, the bone that once surrounded its root begins to resorb because it no longer receives the mechanical stimulus of chewing forces. This process is called alveolar ridge resorption.
Conventional dentures accelerate bone loss. The denture rests on the gum tissue and applies pressure to the surface of the ridge, but it does not transmit forces into the bone the way a tooth root does. Research shows that denture wearers lose an average of 0.5 to 1 millimetre of bone height per year. Over a decade, this can dramatically change the shape of the jaw, cause facial collapse (sunken cheeks and a shortened lower face), and make it progressively harder to achieve a stable denture fit.
Dental implants preserve bone. Because the implant post is anchored in the bone and transmits chewing forces through it, the bone maintains its density and volume around the implant. Studies consistently show that bone levels around well-maintained implants remain stable for 20 years or more. This is the single most important clinical advantage of implants over dentures.
Implant-retained dentures offer partial protection. The two to four implants placed for an overdenture do preserve bone at the implant sites, which helps maintain the front section of the jaw ridge. However, the areas of the jaw without implants still experience some degree of resorption over time, though at a slower rate than with a conventional denture.
Eating and chewing ability
One of the most common complaints from denture wearers is the restriction on what they can eat. Understanding the difference in chewing capacity helps set realistic expectations.
Conventional dentures restore approximately 20 to 25% of natural chewing efficiency. Hard, crunchy, and sticky foods are difficult or off-limits. Biting into an apple, chewing steak, eating corn on the cob, and cracking nuts are either impossible or uncomfortable. Many denture wearers modify their diet to softer foods, which can affect nutrition over time.
Implant-retained dentures improve chewing efficiency to around 60 to 80% of natural teeth. The implant anchorage prevents the denture from lifting, rocking, or shifting, so patients can chew with significantly more force and confidence. Most foods become manageable, though very hard or sticky items still require some caution.
Fixed implant bridges (All-on-4) restore chewing to approximately 85 to 95% of natural teeth. Patients can eat virtually anything, including steak, apples, nuts, and crusty bread, without restriction. The prosthesis is fixed in place and does not move, so biting and chewing feel close to natural teeth.
Comfort and daily experience
Conventional dentures
Full upper dentures cover the palate, which affects taste perception and can trigger a gag reflex in some patients. Lower dentures are notoriously less stable than upper dentures because the tongue and floor of the mouth limit the surface area available for suction. Denture adhesive helps but is messy, needs reapplying, and does not eliminate movement entirely. Many patients describe feeling self-conscious about their dentures slipping during conversation or laughing.
Dental implants
Implant-supported crowns and bridges feel virtually identical to natural teeth. There is no palate coverage, no adhesive, and no awareness of a prosthetic device in the mouth. Patients report that within a few weeks of the final restoration being placed, they forget the teeth are not their own. Implants do not affect speech, taste, or confidence.
Implant-retained dentures
The denture still covers some tissue, including the palate in upper overdentures (though palate-free designs are available with four implants), but the secure clip-on attachment eliminates the fear of the denture dislodging. Patients report a substantial improvement in confidence over conventional dentures, particularly when eating in public and speaking.
Maintenance and care
Conventional dentures
Dentures need to be removed nightly, soaked in a cleaning solution, and brushed daily. The denture base should be checked by a dentist annually for fit, and relining is required every 2 to 3 years as the jaw shape changes. Broken clasps, cracked bases, and lost or chipped teeth on the denture are common repairs. Most conventional dentures need full replacement every 5 to 10 years.
Dental implants
Implant crowns and bridges are cared for the same way as natural teeth: brushing twice daily, flossing or using interdental brushes around the implant, and attending six-monthly check-ups. There is no need to remove anything. The implant-supported crown or bridge may need replacement after 15 to 20 years due to normal wear, but the implant post itself typically lasts a lifetime.
Implant-retained dentures
The denture is removed daily for cleaning, but the implants stay in the jaw permanently. The locator attachments that clip the denture to the implants need replacing every 12 to 18 months (a simple in-chair procedure costing $100 to $300). The denture itself may still need occasional relining and eventual replacement, though it lasts longer than a conventional denture because the implant anchorage reduces the stress and movement that causes wear.
Appearance and facial structure
Both implants and dentures can be made to look like natural teeth. The difference is what happens to the face over time.
Conventional dentures do nothing to prevent the bone loss that leads to facial collapse. Over 10 to 20 years, patients who wear conventional dentures develop a shortened lower face, sunken cheeks, a more prominent chin, deeper creases around the mouth, and thin lips. This premature ageing effect is not cosmetic vanity — it is a direct consequence of the jaw bone shrinking without tooth root or implant stimulation.
Dental implants maintain the bone volume that supports the overlying soft tissue. Patients with implants retain their natural facial proportions and do not develop the sunken appearance associated with long-term denture wear. This is often cited by patients as one of the most valued long-term benefits of choosing implants, especially for people in their 40s, 50s, and 60s who have decades of life ahead of them.
Lifespan comparison
- Conventional denture: 5 to 10 years before replacement, with relines every 2 to 3 years
- Straumann dental implant post: 25 years or longer, commonly lasting a lifetime with proper care
- Implant-supported crown: 15 to 20 years before potential replacement
- Implant-retained denture (prosthesis): 7 to 10 years before the denture component needs replacing; the implants themselves are permanent
- All-on-4 zirconia bridge: 15 to 25 years before potential refurbishment; the implants are permanent
Which option is right for you
There is no single right answer. The best option depends on your clinical situation, your budget, and your priorities.
Conventional dentures may suit you if you need an affordable solution now, are not a candidate for surgery due to health conditions, or are replacing teeth on an interim basis while saving for implants.
Implant-retained dentures may suit you if you currently wear dentures and are frustrated by movement and adhesive, you want better chewing function without the full cost of fixed implants, or you have moderate bone loss that supports two to four implants but not a full-arch fixed bridge.
Individual implants may suit you if you are missing one to several teeth, have adequate bone or are willing to undergo grafting, and want a permanent solution that feels and functions like your natural teeth.
All-on-4 may suit you if you are missing most or all of your teeth, want a fixed full-arch solution, and want to avoid the limitations of any type of denture. All-on-4 is also designed to work with reduced bone volume, often avoiding the need for grafting.

Frequently asked questions
Are dental implants better than dentures?
Dental implants are generally considered the superior long-term replacement for missing teeth because they preserve jaw bone, feel and function like natural teeth, do not slip or move, and can last 25 years or longer with proper care. Dentures are a more affordable short-term solution but accelerate bone loss, restrict what you can eat, require adhesives, and need replacing every 5 to 10 years. The best option depends on your bone health, budget, and how many teeth need replacing. Implant-retained dentures offer a middle ground for patients who want better stability than conventional dentures without the cost of individual implants.
How much do dental implants cost compared to dentures in Melbourne?
A single dental implant with crown costs $4,500 to $6,500 at Pakenham Creek Family Dentist, while a full upper or lower conventional denture costs $1,200 to $3,500. Full-arch All-on-4 implant treatment costs $25,000 to $35,000 per arch. Implant-retained dentures, which snap onto two to four implants for improved stability, cost $8,000 to $15,000 per arch. Although implants cost more upfront, they typically work out cheaper over 20 years because they do not need replacing, rebasing, or relining the way dentures do.
Do dentures cause bone loss?
Yes. Conventional dentures rest on the gum surface and do not provide the mechanical stimulation that jaw bone needs to maintain its density. Without the biting forces transmitted through tooth roots or implants, the alveolar ridge gradually resorbs. Studies show that denture wearers lose an average of 0.5 to 1 millimetre of bone height per year. Over 10 to 20 years, this bone loss changes the shape of the jaw, causes the denture to become loose, alters facial proportions, and can make it progressively harder to fit replacement dentures. Dental implants prevent this by transferring chewing forces directly into the bone, maintaining the same stimulation that natural tooth roots provide.
What are implant-retained dentures?
Implant-retained dentures (also called overdentures or snap-on dentures) are removable dentures that clip onto two to four dental implants placed in the jaw. The implants provide anchorage points that hold the denture firmly in place, eliminating the slipping, clicking, and adhesive problems associated with conventional dentures. The denture is still removable for cleaning but stays securely attached during eating and speaking. This option costs $8,000 to $15,000 per arch at Pakenham Creek Family Dentist, which is significantly less than All-on-4 treatment while offering far better stability than a conventional denture.
Can I eat normally with dentures?
Conventional dentures restore approximately 20 to 25 percent of natural chewing efficiency. Hard foods like apples, raw carrots, steak, and nuts are difficult or impossible to eat comfortably. Sticky foods can dislodge the denture, and biting into food with front denture teeth is unreliable because the base can tip. Implant-retained dentures improve chewing efficiency to around 60 to 80 percent. Fixed implant bridges, such as All-on-4, restore chewing to approximately 85 to 95 percent of natural teeth, allowing patients to eat virtually any food without restriction.
How long do dental implants last compared to dentures?
A Straumann dental implant has a documented 99.6 percent ten-year survival rate and routinely lasts 25 years or longer. The implant post itself can last a lifetime with good oral hygiene, though the crown or bridge attached to it may need replacing after 15 to 20 years. Conventional dentures last 5 to 10 years before needing replacement due to wear, staining, and changes in the jaw shape from ongoing bone loss. Dentures also typically need relining every 2 to 3 years to maintain fit. Over a 20-year period, a patient may go through two to four sets of conventional dentures.
Are dental implants painful compared to getting dentures?
Dental implant surgery is performed under local anaesthetic, so the procedure itself is painless. Post-operative discomfort is typically mild to moderate and manageable with over-the-counter pain relief for 3 to 5 days. Most patients report that implant placement is less uncomfortable than a tooth extraction. Denture fitting is non-surgical and pain-free, though new dentures often cause gum soreness, pressure points, and rubbing during the adjustment period, which can last several weeks. Long-term denture wearers frequently experience ongoing gum irritation and ulceration from the denture base, particularly as bone loss changes the fit.
Can I switch from dentures to dental implants?
Yes. Many patients at Pakenham Creek Family Dentist transition from dentures to implants. The first step is a CBCT scan to assess your remaining bone volume, since long-term denture wear causes bone loss that may need to be addressed with bone grafting before implant placement. Options include individual implants to replace partial dentures, implant-retained overdentures (converting your existing denture to clip onto two to four implants), or All-on-4 full-arch treatment for patients who want a fixed solution. The All-on-4 technique is specifically designed to work with reduced bone by using tilted posterior implants to engage the available bone without grafting.
