Permanent solutions for missing teeth — from single tooth replacement to complete smile restoration with All-on-4 full-arch implants, delivered through expert collaboration.


Missing teeth affect more than just your smile. They impact how you eat, speak, and feel about yourself. They cause bone loss in your jaw. They make other teeth shift out of position. Traditional dentures slip and require adhesives. Bridges require grinding down healthy adjacent teeth.
Dental implants offer a different solution — permanent, stable tooth replacements that look, feel, and function like natural teeth.
After 35 years of restoring smiles across the Eastern Suburbs, Dr Brendan Quill has seen firsthand how dental implants — particularly the All-on-4 system for full-arch restoration — transform not just smiles, but lives. Patients who've struggled with loose dentures or extensive tooth loss finally regain the confidence to eat, laugh, and smile freely.
For surgical implant placement, Dr Quill works in close partnership with leading implant specialist Dr Theo Spyrakis, ensuring you receive expert surgical care combined with the comprehensive restorative dentistry you've come to trust. Whether you're missing a single tooth or need full-arch restoration, this collaborative approach delivers exceptional results.
A dental implant is a titanium post surgically placed into your jawbone to replace a missing tooth root. Once the implant integrates with your bone (a process called osseointegration), it provides a stable foundation for a crown, bridge, or denture.
Think of it as a permanent tooth replacement system:
Unlike bridges or dentures, implants don't rely on adjacent teeth for support. They're independent, self-supporting tooth replacements that preserve jawbone and prevent the facial collapse associated with long-term tooth loss.

Dental implants require two distinct skill sets: surgical placement and restorative work. You benefit from having true experts in both areas.
Dr Theo Spyrakis — implant specialist. One of Sydney's leading implant surgeons, Dr Spyrakis brings specialised training and extensive experience in surgical implant placement. His expertise ensures precise positioning, optimal bone integration, and the highest success rates.
Dr Brendan Quill — restorative dentist. With over 35 years of comprehensive dental experience, Dr Quill designs and creates the final restorations — crowns, bridges, or All-on-4 prostheses — that attach to your implants. His focus is on achieving natural aesthetics, proper function, and comfortable bite.
Why this collaborative model works:
You get the best of both worlds: specialist surgical precision and the personal, long-term care relationship you value.
If you're missing one or a few teeth, single implants offer the most conservative, long-lasting solution.
Benefits of single tooth implants:
The process:
1. Treatment planning with Dr Quill — assessment, treatment plan, and coordination
2. Implant placement by Dr Spyrakis — surgical procedure under local anaesthetic
3. Healing period — 3–6 months for bone integration, monitored by Dr Quill
4. Restoration by Dr Quill — custom crown fabrication and attachment

Missing several adjacent teeth? Rather than individual implants for each tooth, we can place two or more implants and attach a bridge spanning the gap.
Benefits:
This approach works well for replacing 3–4 consecutive missing teeth. Dr Spyrakis places the implants; Dr Quill designs and fits the bridge.
This is where dental implant technology becomes truly life-changing. All-on-4 is a revolutionary technique for replacing an entire arch of teeth (upper, lower, or both) using just four strategically placed implants.
What makes All-on-4 different: rather than replacing each missing tooth individually (which would require 10–14 implants per arch at enormous cost), All-on-4 uses four precisely angled implants to support a full arch of teeth. The back implants are tilted at 45-degree angles to maximise contact with existing bone and avoid the need for bone grafting in most cases.
The result? A complete set of functional, natural-looking teeth supported by just four implants per arch.
The All-on-4 advantage:

All-on-4 is ideal for patients who:
Real-life scenarios where All-on-4 changes lives:
The long-term denture wearer — decades of denture use have caused bone loss. Dentures no longer fit properly, requiring constant adhesive and limiting diet. All-on-4 provides stable, permanent teeth.
The failing dentition — extensive decay, gum disease, or broken teeth across an entire arch. Rather than trying to save compromised teeth, All-on-4 offers a fresh start.
The young accident victim — trauma resulted in losing multiple teeth. All-on-4 restores a full smile and normal function.
The retiree wanting quality of life — tired of denture limitations and ready to enjoy retirement without dietary restrictions or social anxiety about loose teeth.
Phase 1: Initial consultation with Dr Quill — we'll perform a comprehensive examination including 3D CT scans to assess your bone structure, jaw relationship, and overall oral health. This imaging allows precise treatment planning for both the surgical and restorative phases.
Phase 2: Collaborative treatment planning — Dr Quill and Dr Spyrakis work together to plan your case. Using advanced software, they determine the exact position, angle, and depth of each implant, ensuring optimal placement for both stability and aesthetics. Dr Quill begins planning your temporary and final prostheses.
Phase 3: Surgery day with Dr Spyrakis — on the day of your procedure, any remaining failing teeth are removed, four implants per arch are placed using surgical guides for precision, and immediate temporary teeth are attached to the implants (coordinated with Dr Quill's design). You leave the same day with functional teeth. The procedure is performed under local anaesthetic or sedation, depending on your preference and comfort level.
Phase 4: Healing & monitoring with Dr Quill — over the next 3–6 months, implants integrate with your bone while you wear temporary teeth. Dr Quill monitors your progress, makes any necessary adjustments to temporary teeth, and ensures proper healing. You'll follow a modified diet during early healing but can function fairly normally.
Phase 5: Final restoration by Dr Quill — once implants have fully integrated, Dr Quill fabricates your permanent prosthesis — custom teeth designed for optimal aesthetics, function, and durability. These are precisely fitted and attached to your implants, with attention to your bite, smile line, and natural appearance.
Phase 6: Long-term care with Dr Quill — while All-on-4 doesn't decay like natural teeth, regular check-ups and professional cleanings are essential for long-term success. Dr Quill sees you periodically to ensure implants and prosthesis remain healthy, making any adjustments as needed.
If you're facing full-arch tooth replacement, you have choices. Here's the honest comparison.
All-on-4 advantages:
Traditional dentures advantages:
The honest truth: traditional dentures work for some people, especially if budget is the primary concern or if health conditions prevent surgery. But for patients who can undergo the procedure, the quality of life improvement is dramatic. You're not just replacing teeth — you're regaining the ability to eat what you want, speak clearly, and smile confidently without worry. Many patients tell us they wish they'd done All-on-4 years earlier rather than struggling with dentures.
Why not just place an implant for each missing tooth? For full-arch replacement, placing 10–14 individual implants per arch would be more invasive, often require extensive bone grafting, take longer overall, and be far more expensive — without meaningfully improving on the excellent function and aesthetics All-on-4 already achieves.
All-on-4 achieves comparable results — permanent, stable, natural-looking teeth — at a fraction of the complexity. The strategic placement of four implants provides more than adequate support for a full arch. For most patients, All-on-4 represents the optimal balance of cost, invasiveness, and results.
Good candidates typically have:
Factors that may complicate treatment:
During your consultation with Dr Quill, we'll honestly assess whether you're a good candidate. If appropriate, you'll meet with Dr Spyrakis for surgical evaluation before proceeding.
Days 1–7: swelling and mild discomfort (manageable with prescribed medication from Dr Spyrakis), a soft diet, and ice packs and rest to aid healing. You'll have a follow-up with Dr Quill to check temporary teeth, and most patients return to work within 3–5 days.
Weeks 2–6: swelling subsides, more foods are gradually introduced, and you'll have check-ins with Dr Quill for any temporary-teeth adjustments as you become comfortable.
Months 3–6: implants fully integrate with bone, you're eating most foods without issue, and planning begins for your final restoration.
After final restoration: your teeth function like natural teeth. Brush and floss (or use a water flosser) daily, keep up regular check-ups with Dr Quill every 6 months, and have professional cleaning around the implants. All-on-4 prostheses don't decay, but the implants depend on healthy gums — good oral hygiene and regular professional care ensure your investment lasts decades.
