The short answer
All-on-4 replaces all the teeth in one jaw with a fixed bridge held on just 4 implants: two straight implants at the front and two angled implants at the back to avoid the sinuses or nerve and use the bone that is there. It suits people who have lost their teeth or have teeth that cannot be saved, but suitability depends on bone quantity and quality on a CBCT scan. Dr. Khalid Saeed assesses this at Celebrity Smile Center in Duhok.
Many patients in Iraq live with a removable denture that moves when they eat and talk, or with loose teeth from gum disease. The idea of All-on-4 is to replace those teeth with a fixed bridge that does not come out at home, held on four implants. Angling the two back implants can sometimes avoid bone grafting in the back of the jaw, where bone is often thin.
All-on-4 is not right for everyone, though. At Celebrity Smile Center in Duhok, Dr. Khalid Saeed starts with a CBCT scan to measure bone across the whole jaw, and assesses the bite, general health, smoking and diabetes. If the bone is adequate and good quality, four implants may be enough; if bone is weaker or the bite is heavy, six implants (All-on-6) or another option may be advised.
In selected cases a fixed temporary bridge can be fitted shortly after surgery, sometimes called teeth in a day, but that needs the implants to be firmly stable when placed and is only decided during planning and surgery. Once the bone has bonded, usually around 3 to 6 months, the final bridge is made, which may be on a titanium bar with teeth on top, depending on your plan.
Dr. Khalid also treats patients at Creative Arts in Dubai, which he co-founded, but Duhok is his main practice, and patients come from every Iraqi governorate and abroad. Treating inflammation around implants with the Waterlase laser is part of follow-up when needed.

What should you ask? Is planning done with a CBCT scan? Are the teeth and smile designed before surgery? What is the temporary bridge, what is the final bridge, and what are they made of? Is the plan compared with All-on-6 or a titanium bar implant bridge? With Dr. Khalid these answers are written down with the number of visits and price before starting, and any inflammation is treated first.

Read the articleIn many cases yes, and long-term studies support the concept when cases are well selected. But it depends on bone quantity, bone quality and bite force. If bone is weaker or the patient grinds, six implants may be safer. The decision is based on the CBCT scan, not on the treatment's name.
In selected cases a fixed temporary bridge can be fitted shortly after surgery, if the implants are stable enough when placed. It is not promised in advance, because implant stability is measured during surgery. If stability is not enough, another temporary option is used while the bone heals.
Sometimes yes, because the angled back implants are designed to use the bone remaining at the front. If bone is very limited, grafting or another option such as an implant overdenture may be needed. A CBCT scan answers this question accurately.
Both are fixed full-arch bridges. All-on-6 spreads chewing force over six implants instead of four, which usually gives more reserve if one implant has a problem, but it needs more bone and sometimes grafting. All-on-4 suits cases where bone at the back is limited. Both options are explained in your plan.
The bridge is fixed and you do not remove it at home, but the dentist can remove it at the clinic when needed because it is usually screw-retained. You clean it daily with a toothbrush and a special brush under the bridge or a water flosser, and attend regular professional cleaning.
All-on-4 usually needs several visits: examination and scan, surgery, reviews, then the final bridge after healing. The exact number and gaps are written in your plan. Start by sending photos and scans on WhatsApp; you can fly to Erbil and continue by road, checking the current route.
Surgery is done under anaesthesia, the type of which is discussed in your plan. Swelling and soreness for some days are expected and managed with medicines as advised, and this varies between people. A soft diet is needed while healing. No one can promise a pain-free treatment, but comfort is considered at every stage.
Long-term studies report good implant outcomes in well-selected cases, but no lifespan is guaranteed. The teeth or top layer of the bridge may need maintenance or replacement over time. Daily cleaning, not smoking, regular reviews and treating inflammation early matter most.
Look for CBCT planning, a written plan explaining why 4 implants rather than 6, the type of temporary and final bridge, the alternatives, and follow-up after fitting. Dr. Khalid Saeed plans full-arch implants with CBCT at Celebrity Smile Center in Duhok and provides fixed bridges on titanium bars.
Straight after surgery a soft diet is usually advised for a period while the implants integrate, because the temporary bridge needs protecting from heavy load. Once healing is complete and the final bridge is fitted, many patients return to most everyday foods such as bread and cooked meat, while staying careful with very hard things like bones and nut shells. You are given written instructions for each stage.
In suitable cases the temporary bridge is fitted shortly after surgery; it is lighter and designed to protect the implants while they heal, and its shape can be adjusted from your feedback. The final bridge is made after healing from stronger materials with finer cosmetic detail, building on what the temporary showed about speech, smile and bite. The material and timing of each are stated in the written plan.
Yes, All-on-4 can be done on the upper or lower jaw alone if the teeth in the other jaw are healthy or can be treated another way. The bite between both jaws still has to be planned together, because the new bridge will meet the opposing teeth, and some of them may need treatment or adjustment to balance the forces. This is assessed at the examination and explained in the plan, with alternatives for each jaw.
