Flapless all-on-6 implant surgery: what it is and how it works
Flapless all-on-6 implant surgery supports a full arch of fixed teeth on six dental implants, which are placed through the gum without cutting and folding back a flap. The six implants are spaced along the jaw, with a pair at the front and others toward the back, and a bridge of 10 to 14 teeth is screwed onto them. Compared with the four-implant design, the extra two implants shorten the distance between supports, so the load of chewing is spread over more points.
Because the gum is left in place, the surgeon plans from a 3D CBCT scan, often prints a surgical guide, and drills through small openings in the gum. This guide explains what the six-implant layout offers, what flapless adds, how much bone it needs, what it costs in Turkey against the UK, US and Germany, and how to judge a clinic. For the general method see our page on all-on-6 dental implants.
Why six implants instead of four?
Four implants can carry a full arch, but they rely on tilted back implants and a longer bridge extension behind them. Six implants let a surgeon place implants more upright and closer together, so there is less leverage on each one and less strain on the bridge. Dentists often recommend six when the patient has a strong bite or grinds teeth, when the bridge will be long, when a bridge is made of rigid zirconia, or when the jaw has enough bone and the goal is extra security.
A further practical point: if one implant fails, a six-implant bridge may still be supported by the others, so repair is sometimes simpler. The cost is more surgery, more implants to keep clean and a higher price. Neither design is right for every mouth; the choice depends on bone, bite and budget, and your dentist should explain it from your scan. The alternative design is described in our guide to all-on-4 implants.
What does "flapless" mean for six implants?
Placing six implants without a flap means six small gum openings and no incision along the ridge. Possible advantages are less bleeding, less swelling, less pain and quicker gum healing, with few or no stitches. Studies of guided flapless placement report good implant survival in suitable patients. The limit is visibility: the surgeon cannot see the bone, so the technique needs enough ridge width, firm gum, a precise guide and an experienced operator.
With six implants the bone requirement is higher than for four, because each implant needs its own space in good bone. If the ridge needs reshaping, if bone is thin at the back or if the sinus is low, a flap or grafting may be required. Flapless suitability must be confirmed on the scan, not assumed.
How much does flapless all-on-6 surgery cost in Turkey?
The ranges below are approximate for one arch including a fixed bridge, not hospital quotes. Each clinic confirms its price in a written plan after reviewing your scan.
| Country | Approximate cost range (one arch) |
|---|---|
| Turkey | €4,000 – €9,000 |
| United Kingdom | €10,000 – €19,000 |
| United States | €16,000 – €32,000 |
| Germany | €9,000 – €17,000 |
What changes the price: the implant brand, the bridge material (acrylic, composite or zirconia), whether teeth must be extracted, bone grafting, the scan and guide, sedation or general anaesthesia, and whether one or both arches are treated. A package normally includes the scan, six implants, abutments, a temporary and a final bridge, extractions, medication and airport transfers. Ask for the implant brand in writing and for the warranty terms for implants and bridge.
All-on-6 compared with all-on-4 and a removable denture
The choice is usually between fewer implants at lower cost and more implants for broader support. The table sets out the roles of each approach.
| Option | Best suited to | Typical limits |
|---|---|---|
| Flapless all-on-6 | Good bone volume; strong bite; long bridge; wish for extra support | Higher cost; needs more bone; more implants to maintain |
| All-on-4 | Limited bone at the back; lower budget | Tilted implants and longer bridge extension; less margin if one fails |
| Overdenture on 2 to 4 implants | Lower jaw; removable option with lower cost | Removable; less chewing force than a fixed bridge |
If you want a fixed bridge but would like a lower price, ask how the plan differs with four implants. If bone in the upper jaw is very limited, a computer-guided all-on-6 plan may need grafting or another design.
Who is a good candidate, and who is not?
Good candidates are adults with failing or missing teeth, enough bone width and height shown on a CBCT scan, healthy gum tissue and good oral hygiene, who want a fixed bridge. You may need a flap, bone grafting or a different design if:
- the ridge is narrow, uneven or has sharp bone that needs reshaping;
- there is little attached gum around the ridge;
- gum disease or infection is active and not yet treated;
- you smoke heavily, have uncontrolled diabetes, take bisphosphonates, had jaw radiotherapy or grind your teeth severely.
These conditions do not always rule treatment out, but they raise the risk of implant failure and need the dentist's judgement before you travel.
What happens during the operation, step by step?
After the consultation and the scan, the clinic plans six positions on screen and may print a guide. On the day:
- You receive local anaesthetic with sedation or general anaesthesia, which is common for a full arch.
- Hopeless teeth are removed and the sockets cleaned.
- The guide is fixed and six implants are placed through the gum at the planned angles and depths.
- Abutments are attached and a temporary bridge is fitted when the implants are stable enough to take a load; otherwise healing caps are placed.
The operation takes about two to four hours per arch. Some clinics fit the temporary bridge on the same day; see same-day all-on-6 for what that involves.
Recovery and your trip to Turkey, step by step
Expect swelling, bruising and soreness for the first three to five days, usually less intense than with a flap; light oozing is normal. A soft diet is advised for six to ten weeks, and hard, sticky or crunchy food should be avoided while the temporary bridge is in place. Keep the area clean with the prescribed mouthwash, brush gently and avoid smoking. Typical trip patterns are:
- Surgery trip: five to eight nights, including the temporary bridge and a check.
- Final bridge: about three to six months later, once the bone has fused with the implants, with a stay of around four to seven nights.
Some clinics offer a faster programme; confirm in writing how many trips are planned and what happens if an implant is not stable at the check.
Flapless all-on-6 before and after: what are realistic results?
Photographs usually show a full arch of even teeth fixed in place and a more confident smile. They do not show the settling period: the temporary bridge is for function, the gums remodel around the implants over weeks, and the final bridge is only made when the tissue has stabilised. Chewing is usually much improved, though it is not identical to natural teeth and you may need to adapt. Bridge parts wear, and attachments or screws may need tightening over the years. Ask for case examples with a similar starting situation, and be cautious of galleries showing only cosmetic cases.
Risks and complications of flapless all-on-6
Common effects are swelling, bruising, soreness and minor bleeding. Other risks are infection, early loss of an implant, bone loss around implants (peri-implantitis), loose screws, fractured bridge material, numbness if a nerve is irritated in the lower jaw and sinus problems in the upper jaw. A flapless approach adds the risk of perforating thin bone because the surgeon cannot see it. The NHS and the American Academy of Periodontology note that smoking, poor plaque control and untreated gum disease raise the risk of implant complications. Ask what the clinic does if an implant fails, whether replacement is included and who reviews you at home.
How to choose a clinic, and red flags
Look for a clinic where an implant dentist or oral surgeon plans from a CBCT scan and names the implant brand, bridge material and warranty in a written plan. Red flags include a fixed price with no scan, a promise that six implants suit everyone, no discussion of bone volume, vague guarantee wording and pressure to pay a large deposit.

Frequently asked questions
It places six implants through small openings in the gum without cutting a flap, then supports a fixed full-arch bridge on them. Planning relies on a 3D scan and usually a surgical guide because the bone is not seen directly.
Reviews of full-arch fixed implant bridges report high implant survival over five to ten years, and guided flapless placement shows similar results in suitable patients. Bridge wear and loose screws are more common than implant loss, so maintenance matters.
Approximate ranges are €4,000 to €9,000 per arch in Turkey, against about €10,000 to €19,000 in the UK. The price depends on the implant brand, bridge material, extractions, grafting and what the written quote includes.
All-on-4 uses four implants, two of them tilted, while all-on-6 uses six implants spread along the jaw to share the bite load. All-on-6 needs more bone and costs more, but gives extra support for strong bites or long bridges.
Enough width and height for six implants, which a CBCT scan shows. If bone is thin or the sinus is low, a surgeon may graft bone, use a flap or recommend four implants or another design.
Often there is less swelling, bleeding and soreness because the gum is not opened, and stitches are rarely needed. A full-arch operation still needs sedation or anaesthesia and a soft diet for several weeks.
If the implants are stable, many clinics fit a temporary fixed bridge on the day or within a few days. If not, healing caps are placed and the bridge follows later, so ask what happens in each case.
Swelling and soreness settle within one to two weeks, a soft diet is advised for six to ten weeks, and the final bridge usually follows after three to six months once the bone has fused with the implants.
Risks include infection, implant failure, bone loss around implants, loose screws, bridge fracture and, with flapless surgery, perforation of thin bone. Smoking, poor hygiene and uncontrolled diabetes raise these risks.
Plan five to eight nights for surgery, the temporary bridge and checks. Many clinics ask you to return after three to six months for the final bridge, so confirm the number of trips before booking.
