Full-Arch Dental Implants & All-on-4® in Hamilton
If you are tired of loose dentures, avoiding certain foods, or hiding your smile, full-arch dental implants may be a life-changing option. Instead of replacing each tooth one by one, this treatment uses a small number of carefully placed implants to support a full set of fixed teeth in the upper or lower jaw, or both.
At Spinel Dental in Hamilton, we use advanced 3D imaging and trusted implant systems to plan every case with precision. During your consultation, we will look at your teeth, gums, and jawbone and discuss whether an All-on-4® or All-on-6® style treatment is the safest, most predictable way to restore your smile.

A message from our
Implant Provider Dentist
Worrying about dentures that slip, rub sore spots, or make it hard to enjoy your favourite foods is incredibly frustrating. With full‑arch dental implants, you can forget about adhesives and looseness and enjoy a stable, natural‑looking smile that lets you eat, speak, and live with confidence again.

Ready to
talk about your
Full Arch
Dental Implants?
If you are missing most or all of your teeth, we can help you explore stable, full‑arch implant solutions in a comfortable, no‑pressure consultation. Our team will explain whether full‑arch dental implants are right for you and walk you through what to expect at every step of treatment.
What is the All-on-4® Dental Implant
Treatment Concept?
All-on-4® is a modern way to replace a full arch of teeth using as few as four implants in the jaw. Instead of an implant for every missing tooth, four implants are positioned in areas of stronger bone and used to hold a full, fixed bridge of teeth. Think of it like a set of permanent dentures that are screwed in place and do not come out at night.
Because the implants are placed at planned angles and positions, many patients can avoid or reduce the need for bone grafting compared to traditional implant approaches. In some cases, a temporary set of teeth can even be attached on the same day as surgery, which is why people often hear the phrase “teeth in a day” for this type of treatment.
The Life-Changing Benefits of
Fixed Dental Implants
Fixed full-arch implants are designed to feel as close as possible to having your own strong teeth again. Because the teeth are anchored to implants, they can offer much better stability than traditional dentures, so you can speak, laugh, and chew with more confidence. Many patients find they can enjoy a wider range of foods again, including many of the things they stopped eating because of pain or loose dentures.
These restorations are also slimmer than some standard upper dentures because there is usually no need for a full plastic plate covering the roof of the mouth. That often means better taste, more comfort, and a more natural feel. Implants also help stimulate the jawbone, which can slow down the bone loss that usually happens after teeth are removed.
All-on-4 vs. All-on-6
Which is Right for You?
You may see both “All-on-4” and “All-on-6” used to describe full-arch implant treatment. Both approaches use implants to support a full set of fixed teeth; the main difference is the number of implants used for support and how the biting forces are shared across your jaw.
Some patients do very well with four implants, while others benefit from six implants because they have stronger biting forces, wider arches, or areas of bone that make extra support a safer long-term choice. During your planning visit, we use 3D scans and clinical measurements to decide how many implants are appropriate for your case rather than forcing every patient into a one-size-fits-all solution.
Aspect | All-on-4 | All-on-6 |
|---|---|---|
Best suited for | Patients with more bone loss who want to avoid extensive grafting and keep costs as efficient as possible | Patients with stronger bone, higher bite forces, or who want maximum support and future flexibility |
Longevity (when well-planned) | High long‑term success rates in properly selected patients; 5‑year survival over 95% in studies | Similarly high success; extra implants may reduce some mechanical risks in higher‑force cases |
Stability and support | Very stable for many patients and well-studied when carefully planned | Even more support and “backup” because chewing forces are spread over six implants |
Cost | Generally lower upfront because there are fewer implants and slightly less surgery time | Typically higher upfront cost but with added support and implant “redundancy” |
Chance of needing bone grafting | Often lower, thanks to angling of the back implants | Can be higher if there is not enough bone where vertical implants are planned |
Biomechanics / load on each implant | Slightly more stress per implant because four implants do the work | Less stress on each implant, which can be helpful for strong bite forces or grinding |
Treatment time and surgery | Slightly shorter surgery and less hardware placed | Surgery can be a bit longer and more involved because more implants are placed |
Typical bone requirement | Designed to work even when bone has thinned; often avoids sinus lifts or major grafting | Usually best when you have stronger bone volume; may need more bone in key areas |
Number of implants per arch | 4 implants support one full arch of teeth | 6 implants support one full arch of teeth |
Implant positioning | Front implants usually straight, back implants often placed at an angle to use existing bone and reduce grafting | Implants often placed more vertically, spreading support over a wider area of the jaw |

Recovery & aftercare tips after All‑on‑4 treatment
Healing after All‑on‑4 surgery takes time, and following your instructions closely helps protect your implants. Some swelling, bruising, and soreness in the first few days is normal and usually improves after 48–72 hours.
Soft foods only at first
Stick to cool, soft foods like yogurt, smoothies, scrambled eggs, mashed potatoes, soup, and soft pasta in the early healing phase. Avoid hard, crunchy, sticky, or spicy foods and very hot drinks until we tell you it is safe to reintroduce them.
Rest and protect the area
Take it easy for the first few days and avoid strenuous exercise or heavy lifting for at least the first week. Do not chew directly on the implant area, and follow our medication instructions exactly as prescribed.
Keep your mouth clean
Use a soft toothbrush and any recommended rinses as directed to keep the area clean without disturbing the surgical sites. Good daily hygiene and attending all follow‑up visits are key to long‑term implant success.

Who is a good candidate for All‑on‑4?
All‑on‑4 and other full‑arch implant options are designed for people who are ready to move away from failing teeth or loose dentures and want a more stable, long‑term solution. You may be a good candidate if some of the points below sound like you.
Significant tooth loss or failing teeth
All‑on‑4 is usually recommended for patients who have lost most or all of their teeth in the upper jaw, lower jaw, or both, or who have many teeth that can no longer be predictably restored. It is also a strong option for people who are unhappy with loose or uncomfortable full dentures.
Enough bone to support implants
Even though All‑on‑4 is designed to work with less bone than traditional methods, you still need enough healthy jawbone to secure the implants. During your consultation, we assess your bone using 3D scans and, if needed, discuss options such as different implant positions or additional procedures to improve support.
Healthy gums and good overall health
Healthy gum tissue and control of any active gum disease or infection are important for implant success. In general, candidates should also be well enough medically to have oral surgery, with conditions like diabetes or blood‑pressure issues monitored and managed appropriately in coordination with your physician when needed.
Commitment to healing and hygiene
All‑on‑4 is a long‑term investment. Good candidates are willing to follow aftercare instructions, maintain excellent daily cleaning around their implants and bridge, attend follow‑up visits, and make lifestyle changes if advised (for example, cutting down on smoking). These habits play a big role in how well your implants perform over time.
If you aren’t sure whether you qualify, a complimentary consultation with 3D imaging is the best way to find out. Many people who think they may “not have enough bone” or are “too late” for implants are pleasantly surprised by the options available after a proper full‑arch assessment.
