All-on-4
/ All-on-6.
Your Entire Jaw
Rebuilt.
Missing all your teeth — or on the verge of losing them all? All-on-4 and All-on-6 replace the entire upper or lower jaw with a fixed, permanent bridge supported by just 4 or 6 implants. No removable dentures. No bone graft in most cases. A provisional bridge delivered the same day as surgery.
at 30–45°
Greater stability
An entire jaw of fixed teeth —
supported by 4 or 6 implants.
All-on-4 and All-on-6 are full-arch implant concepts — the gold standard for replacing an entire jaw of teeth. Rather than placing one implant per missing tooth (which would require 14+ implants per arch), both concepts use a small number of strategically positioned implants to anchor a full-arch fixed bridge that replaces all teeth in one or both jaws simultaneously.
The key engineering insight behind both systems is the use of angled posterior implants — tilted at 30–45° — which allows them to engage denser anterior bone regions and achieve greater bone contact without needing a bone graft. These tilted implants effectively extend the implant-supported region backwards, giving the bridge a wider base of support.
All-on-4 uses 4 implants per arch (2 axial at the front, 2 tilted at the back). All-on-6 uses 6 implants (4 axial, 2 tilted), distributing bite forces more widely and achieving higher long-term stability — particularly important for patients with bruxism or greater bite force demands. A provisional fixed bridge is delivered the same day as surgery in most cases, with a final definitive bridge fitted after osseointegration.
Unlike full dentures, the All-on-4/6 bridge is permanently fixed in the mouth. It does not come out, does not move, and does not require adhesives. Cleaned like natural teeth.
The angled posterior implants engage denser bone regions that are typically present even in patients with moderate bone loss — avoiding the need for grafting in the majority of cases.
A fixed provisional bridge is delivered on the day of surgery or within 48 hours — immediately restoring appearance and function. Final definitive bridge replaces it after osseointegration.
Replacing an entire arch with 14 individual implants is significantly more expensive and surgically complex. All-on-4/6 achieves a comparable functional and aesthetic result with fewer implants and one surgical appointment.
Every All-on-4/6 at Hassaan Dental begins with a CBCT 3D scan — mapping bone density, nerve pathways, sinus anatomy, and optimal implant angles before surgery begins. No guesswork.
Who is this right for —
and who needs a different approach?
All-on-4 and All-on-6 are designed for patients facing full-arch tooth loss. The right protocol is determined by CBCT scan, not assumption.
"My dentures move when I eat and I can't taste food properly. I want something permanent that feels like real teeth."
"All my upper teeth are loose or cracked. I need everything extracted and replaced in one go — I can't go months without teeth."
"All-on-6 costs £25,000 in London. I need the full upper arch done and I'm visiting family in Islamabad for 2 weeks."
From consultation to
fixed final bridge.
Every stage is planned digitally before surgery begins. Dr. Haris walks you through the complete process at your CBCT consultation — nothing proceeds without your full understanding and agreement.
A CBCT 3D scan provides a complete volumetric map of your jaw — bone density at every point, sinus boundaries, nerve canals, and available bone height and width. This scan determines whether All-on-4 or All-on-6 is appropriate, the optimal implant positions and angles, and whether any remaining teeth require extraction. A full 3D digital implant plan is prepared — showing each implant's position on your actual jaw anatomy. Complete transparent cost breakdown presented before any commitment is made.
If remaining teeth are failing, they are extracted in the same appointment as implant placement — typically under the same local anaesthesia session. Immediate implant placement into fresh extraction sites is performed where bone walls are intact and primary stability can be confirmed. This reduces total treatment time and avoids a separate extraction appointment with a healing gap.
Under local anaesthesia, Dr. Haris places 4 or 6 implants according to the pre-planned positions — 2 axial implants in the anterior region and 2–4 angled implants (30–45°) posteriorly. Insertion torque and ISQ measurements confirm primary stability at each implant site before the provisional bridge is attached. The surgical protocol is guided at every step by the pre-operative CBCT plan.
Immediately after implant placement, an intraoral digital scan captures the precise positions of all implant heads. This data is used to fabricate the provisional full-arch bridge — an acrylic or PMMA prosthesis designed to restore your smile immediately while osseointegration progresses. The provisional bridge is fitted the same day or within 48 hours of surgery, attached to the implants with screws.
The provisional bridge remains in place throughout the osseointegration period — you can eat, speak, and smile normally during this time. The bridge is not load-free — controlled functional loading has been shown to support, rather than hinder, bone bonding when implants have sufficient primary stability. A review at 6–8 weeks checks healing, gum health, and bridge fit. A second review at 3–4 months assesses osseointegration progress.
Once osseointegration is confirmed, the provisional bridge is removed and final impressions taken (digital or conventional) for the definitive bridge. The final prosthesis — typically full-arch zirconia or porcelain-fused-to-metal — is fabricated to precisely match your provisional bridge shape and bite, then fitted and torque-tightened to the implant abutments. The access holes are sealed with composite. You leave with your final, permanent, fixed full-arch restoration.

What you'll pay —
nothing more.
Full-arch pricing depends on the number of implants, type of prosthesis, and case complexity — all confirmed after your CBCT assessment. Here are the per-implant starting rates and what each arch typically involves.
Basal: 4 × 70,000 = PKR 2,80,000
Basal: 6 × 70,000 = PKR 4,20,000
Important: Unit prices remain the same; final treatment cost may vary after clinical examination. The number of implants and type of bridge are confirmed by CBCT assessment. A full, transparent cost breakdown is provided at your PKR 1,000 consultation — nothing is committed before you understand and agree the complete plan and cost.
