Both can restore your ability to eat, speak, and get through daily life without thinking twice about your teeth, but they differ considerably in surgical approach, treatment timeline, cost, and who they're suited to.\n\nCollins Street Specialist Centre (CSSC) is located in Melbourne's CBD. Our team includes periodontists, prosthodontists, and oral and maxillofacial surgeons who work together to plan and deliver full-arch implant treatment. That integrated model matters because each case is assessed by specialists whose combined expertise shapes every stage of what happens.\n\nThis guide explains both approaches in detail, so you can understand the clinical reasoning behind each and which might suit your situation better.\n\n---\n\n## Understanding full-arch tooth replacement\n\nBefore comparing the two approaches, it helps to understand the clinical problem they both address. When all — or most — of the teeth in an arch (upper jaw, lower jaw, or both) are missing, the conventional options have historically included:\n\n- **Complete dentures:** Removable prosthetics that rest on the gum tissue. Accessible in terms of cost, but frequently uncomfortable, prone to instability (particularly lower dentures), and they don't stop ongoing bone resorption.\n- **Implant-supported overdentures:** A removable denture that clips onto two to four implants, offering better retention than conventional dentures, but still removed for cleaning and sleeping.\n- **Fixed implant bridges:** A permanent, non-removable prosthesis supported by dental implants. Both All-on-4 and traditional full-arch implant approaches fall into this category.\n\nBoth All-on-4 and traditional implant bridges aim to give you a fixed set of teeth that look, function, and feel like natural dentition. The real differences lie in the number of implants used, how they're positioned, whether bone grafting is needed, and the overall treatment pathway.\n\n---\n\n## What is the All-on-4 concept?\n\nAll-on-4 uses four strategically positioned dental implants to support a complete arch of fixed teeth. The \"4\" refers to the four implants per arch that anchor the prosthesis.\n\n### How All-on-4 works\n\nThe defining clinical feature of All-on-4 is the deliberate angulation of the posterior implants. Rather than placing all four implants vertically, the two back implants are tilted at an angle — typically between 30 and 45 degrees. This achieves several things:\n\n- **Using available bone:** By angling the posterior implants, the surgeon can engage denser anterior bone and work around areas of posterior resorption that are common in patients who've been edentulous for some time. This frequently eliminates the need for bone augmentation.\n- **Longer implant bodies:** The angled trajectory allows for longer implants, increasing bone contact and improving primary stability.\n- **Better load distribution:** Spreading four implants across the arch distributes chewing forces more evenly across the prosthesis.\n\n### The All-on-4 treatment journey\n\n**Stage 1 — Comprehensive assessment:** Three-dimensional imaging (cone beam computed tomography, or CBCT), clinical photographs, impressions, and a thorough intraoral examination form the basis of your treatment plan. Digital planning software, including guided surgery protocols in many cases, is used to map implant positions precisely before any surgery takes place.\n\n**Stage 2 — Surgery day:** All four implants are placed in a single session, under local anaesthesia with intravenous sedation, or general anaesthesia where clinically indicated or preferred. In most cases, a provisional fixed bridge is attached to the implants the same day, so you leave with a functional set of teeth.\n\n**Stage 3 — Healing period:** Over the following three to six months, the implants undergo osseointegration — the process by which bone grows and bonds directly to the implant surface. The provisional prosthesis is functional during this phase, but it's not the final restoration.\n\n**Stage 4 — Final prosthesis:** Once osseointegration is confirmed, the provisional bridge is replaced with the definitive restoration, custom-fabricated for aesthetics, occlusal function, and long-term durability.\n\n### Clinical advantages of All-on-4\n\nFour implants per arch simplifies the surgical procedure and reduces overall cost compared to approaches requiring six to eight implants. The angled implant geometry is specifically designed to work with the residual bone that's typically present even in patients with moderate resorption, so bone grafting is frequently avoided. For many patients, leaving surgery with a functional, non-removable provisional prosthesis is both clinically and psychologically significant.\n\nBecause bone grafting is often unnecessary, the total treatment duration is considerably shorter than traditional full-arch approaches. The All-on-4 concept has been studied extensively for more than two decades, with cumulative implant survival rates exceeding 95% at ten or more years in peer-reviewed literature. Fewer implants and the frequent elimination of bone augmentation also translate to a lower overall cost.\n\n### Clinical considerations\n\nThe All-on-4 bridge functions as one continuous unit. If a section sustains damage, the entire prosthesis may need to be removed for repair — worth factoring into long-term maintenance planning. Maintaining hygiene beneath and around a fixed full-arch bridge also requires specific techniques and tools; water flossers and interdental brushes are typically recommended, which is different from caring for individual implant crowns.\n\nWhilst All-on-4 is clinically versatile, patients with very severe bone loss may still require augmentation or an alternative approach. The choice of prosthetic material — high-density acrylic or zirconia are the most common options — has implications for aesthetics, mechanical durability, and cost, and is worth discussing in detail at your consultation.\n\n---\n\n## What are traditional full-arch implants?\n\nThe conventional approach to full-arch implant rehabilitation uses more implants — typically six to eight per arch — placed in a predominantly vertical orientation throughout the jaw. Each implant supports a portion of the prosthetic bridge, which may be a single continuous full-arch structure or fabricated in discrete sections.\n\n### How traditional full-arch implants work\n\n**Stage 1 — Assessment and planning:** As with All-on-4, comprehensive three-dimensional imaging and digital planning are used to determine optimal implant positions before surgery.\n\n**Stage 2 — Bone grafting (where indicated):** Because implants are placed vertically, adequate bone volume — in both height and width — is required at each proposed site. Bone loss is common after prolonged tooth absence or years of denture wear, and augmentation procedures such as ridge augmentation or sinus lift surgery may be necessary before implants can be placed. These grafting procedures typically require four to nine months of healing before implant placement can proceed.\n\n**Stage 3 — Implant placement:** Six to eight implants are placed per arch. Depending on case complexity and whether grafting has been performed, this may occur in a single session or across staged appointments.\n\n**Stage 4 — Healing:** A three-to-six-month osseointegration period follows implant placement. During this time, patients typically wear a temporary removable denture.\n\n**Stage 5 — Final restoration:** Custom-fabricated crowns or bridge segments are attached to the integrated implants to complete the restoration.\n\n### Clinical advantages of traditional full-arch implants\n\nMore implants provide broader distribution of chewing forces and potentially greater structural support for the prosthesis. Where the bridge is fabricated in sections, damage to one area means repairing or replacing only that segment, not the entire prosthesis. In selected cases, each implant may support its own individual crown, more closely replicating the appearance and hygiene accessibility of natural dentition. A greater number of implant positions also affords more flexibility in prosthetic design. And if an individual implant fails, the remaining implants can often continue supporting the restoration without compromising the overall outcome.\n\n### Clinical considerations\n\nPlacing six to eight implants is a more involved surgical procedure than placing four, with corresponding implications for operative time and recovery. Patients with significant posterior bone loss — a common presentation — will often need one or more augmentation procedures before implant placement, adding both time and cost. When bone grafting is incorporated, the total treatment duration from first surgical intervention to final prosthesis delivery may extend to twelve to eighteen months or beyond. The combination of additional implants, potential bone augmentation, and more complex prosthetic design generally results in a higher overall cost. Patients requiring bone grafting may also spend a considerable number of months wearing a temporary removable denture before their definitive fixed prosthesis is placed.\n\n---\n\n## Detailed comparison\n\n### Number of implants\n\nAll-on-4 uses four implants per arch — eight total for both jaws. Traditional full-arch uses six to eight per arch — twelve to sixteen total for both jaws.\n\n### Need for bone grafting\n\nAll-on-4 frequently doesn't require bone grafting, because the angled posterior implants are specifically designed to work with the bone that's typically available even in partially resorbed jaws. Traditional full-arch commonly does require grafting, particularly in the posterior jaw where resorption is most pronounced after tooth loss. Sinus lift procedures and ridge augmentation are frequently indicated.\n\n### Treatment timeline\n\nAll-on-4 typically runs three to six months from surgery to final prosthesis delivery, with provisional fixed teeth placed on the same day as implant surgery in most cases. Traditional full-arch may range from six to eighteen months or longer, depending on whether bone augmentation is required and the extent of any staged surgical approach.\n\n### Same-day fixed teeth\n\nWith All-on-4, most patients receive a provisional fixed bridge on the day of implant placement. With traditional full-arch, this generally isn't possible where bone grafting is required — patients typically wear a temporary removable denture throughout the healing phases.\n\n### Cost\n\nFull-arch implant rehabilitation is a significant financial commitment regardless of approach. In Melbourne, indicative fee ranges are:\n\n- **All-on-4:** From approximately $20,000–$30,000 AUD per arch for the complete treatment course, covering implant placement, provisional prosthesis, and definitive restoration.\n- **Traditional (six to eight implants):** From approximately $30,000–$50,000 AUD per arch, particularly where bone augmentation is involved.\n\nThese are indicative ranges only. Actual fees depend on your specific clinical presentation, the materials selected for the definitive prosthesis, and the complexity of your case. At CSSC, detailed fee estimates are provided following your initial comprehensive assessment.\n\n### Longevity and clinical success rates\n\nBoth approaches are supported by solid long-term clinical evidence. Published studies report All-on-4 implant survival rates exceeding 95% at ten or more years. The prosthetic bridge itself may need replacement or refurbishment after ten to fifteen years, depending on material selection and how the occlusion loads it. Traditional full-arch reports comparable implant survival rates in the literature, and the additional implants provide a degree of redundancy — the loss of a single implant is less likely to compromise the overall restoration.\n\n### Recovery\n\nMost All-on-4 patients are back to normal daily activities within about a week. Some swelling and postoperative discomfort is expected in the first few days, and a soft diet is recommended for the first three months whilst osseointegration takes place. Recovery from traditional full-arch depends on the extent of surgery. Where bone grafting is involved, there may be multiple distinct recovery periods. The recovery from implant placement itself is broadly comparable to All-on-4.\n\n---\n\n## Candidacy considerations\n\n### All-on-4 may suit you if:\n\n- You have moderate bone resorption and want to avoid bone grafting\n- You want fixed teeth as quickly as possible, including same-day provisional teeth\n- You're currently wearing dentures and want a permanent, non-removable alternative\n- Cost-effectiveness is an important factor in your decision\n- You have failing dentition requiring full-arch extraction and immediate replacement\n- You prefer a less surgically complex pathway to full-arch restoration\n\n### Traditional full-arch may suit you if:\n\n- You have sufficient residual bone and are comfortable with a longer treatment timeline\n- You prefer individual implant crowns over a continuous full-arch bridge\n- A segmented prosthetic design is clinically or aesthetically preferable for your case\n- Maximum structural redundancy across the restoration is a priority\n- Some natural teeth can be retained and only partial arch replacement is needed\n\n### When the clinical picture is more complex\n\nSome patients present with challenges that don't fit a straightforward treatment pathway — severe bone resorption, systemic medical conditions that affect healing, compromised soft tissue, or complex occlusal relationships. This is where CSSC's multidisciplinary model provides a genuine clinical advantage. Our periodontists, oral and maxillofacial surgeons, and prosthodontists review complex cases together, drawing on their respective areas of expertise to develop plans that are genuinely tailored to each patient's anatomy, medical history, and clinical goals.\n\n---\n\n## The role of each specialist\n\nFull-arch implant rehabilitation involves multiple dental specialties. At CSSC, each discipline is represented within a single practice at 220 Collins Street, Melbourne CBD:\n\n**Periodontists** specialise in the supporting structures of the teeth — the periodontal tissues and alveolar bone. They may place implants, perform bone augmentation, and manage soft tissue architecture to achieve the best aesthetic and functional outcome.\n\n**Oral and maxillofacial surgeons** manage the more complex surgical aspects of treatment, including implant placement in anatomically challenging sites, bone grafting, sinus lift surgery, and cases requiring general anaesthesia.\n\n**Prosthodontists** are responsible for designing, fabricating, and delivering the prosthetic restoration — whether a full-arch bridge or individual crowns. Their role covers ensuring the final result is aesthetically refined, occlusally sound, and built for long-term durability.\n\nThis integrated specialist model is uncommon in Australian dental practice. Rather than being referred between multiple independent practices across Melbourne, patients at CSSC receive coordinated specialist care within a single environment. Treatment planning decisions are made collaboratively, and communication between treating clinicians is direct and ongoing.\n\n---\n\n## Questions worth raising at your consultation\n\n1. Based on my bone levels and general health, am I a suitable candidate for All-on-4, traditional full-arch implants, or both?\n2. Is bone grafting likely in my case, and if so, how would that affect the timeline and overall cost?\n3. What prosthetic material options are available for the definitive restoration, and what are the trade-offs of each?\n4. Is it likely I'll be able to receive provisional fixed teeth on the day of implant surgery?\n5. What is the total estimated fee for my specific case, inclusive of all treatment stages?\n6. What does the ongoing maintenance schedule look like after treatment is complete?\n7. What's the recommended course of action if an implant fails after treatment?\n\n---\n\n## Life after full-arch implant treatment\n\nRegardless of which approach is selected, the quality-of-life outcomes associated with implant-supported fixed teeth are consistently meaningful. Patients commonly report:\n\n- **Restored dietary freedom** — being able to eat steak, fresh apples, and corn on the cob that were uncomfortable or impossible to manage with conventional dentures\n- **No more adhesives or removable appliances** — the prosthesis is fixed in place and doesn't move during eating or speaking\n- **Natural appearance** — contemporary prosthetic materials and techniques replicate the look of natural teeth and gingival tissue with a high degree of fidelity\n- **Improved speech clarity** — stable, well-fitting teeth eliminate the slurring and clicking that can accompany ill-fitting dentures\n- **Better nutritional intake** — restored chewing function supports more effective digestion and general health\n- **Greater social confidence** — patients frequently describe relief at no longer worrying about prosthetic movement during conversation or social interaction\n\nMaintaining the long-term health of implant-supported teeth requires a consistent oral hygiene routine — daily brushing, specialised interdental cleaning tools such as water flossers — along with professional maintenance appointments every three to six months and periodic clinical reviews to monitor implant health and prosthetic integrity.\n\n---\n\n## Taking the first step\n\nIf you're currently managing the limitations of conventional dentures, living with failing dentition, or dealing with the impact of missing teeth on your confidence and daily function, full-arch implant rehabilitation offers a clinically sound and durable path to restoration. The right starting point is a comprehensive assessment, where the treating team can evaluate your specific clinical presentation and recommend the approach most likely to deliver the best long-term outcome for your situation.\n\nWe invite you to book a consultation at Collins Street Specialist Centre, where our periodontists, oral and maxillofacial surgeons, and prosthodontists will assess your clinical situation in detail and outline a recommended treatment pathway, with multidisciplinary input at every stage.\n\n*Collins Street Specialist Centre is located in the Manchester Unity Building,
