All-on-6 and Existing Partial Implants: Can You Combine?

All-on-6 and Existing Partial Implants: Can You Combine?

If you currently wear a partial denture or have a few individual dental implants already in place, you might wonder whether you can upgrade to an All-on-6 bridge without removing your existing work. It is a sensible question, especially when you have already invested time and money in your oral health. The short answer is: yes, in many cases it is possible to combine existing partial implants with a new All-on-6 restoration, but the approach depends on the condition, position, and stability of your current implants. This article will guide you through the clinical considerations, costs, and practical steps for UK patients, and explain why Taki Dent in Antalya should be your first port of call for a free, expert assessment.

Understanding All-on-6 and Its Relationship with Existing Implants

All-on-6 is a full-arch restoration that uses six precisely placed dental implants to support a fixed, non-removable bridge of 12 to 14 teeth. It is designed for patients who have lost most or all of their teeth in one or both jaws. The key advantage over traditional dentures is stability: the bridge is screwed into the implants, so it does not move, click, or cause sore spots. For UK patients, the procedure is often life-changing, restoring the ability to eat, smile, and speak with confidence.

When you already have partial implants—perhaps two or three individual implants that support a single crown or a small bridge—the question arises: can these be incorporated into a new All-on-6 plan? The answer is not a simple yes or no. It depends on several factors, including the bone density around your existing implants, their angulation, and whether they are healthy and well-integrated. In some cases, your existing implants can be retained and used as part of the six-implant foundation. In others, they may need to be removed and replaced, or left in place but not connected to the new bridge.

The Clinical Assessment: What Your Dentist Will Check

Before any decision is made, a thorough clinical and radiographic evaluation is essential. Your dentist will take a 3D CBCT scan to assess the bone volume and the position of your existing implants. They will also check for signs of peri-implantitis (inflammation around the implant), bone loss, or mechanical failure. The British Dental Association (bda.org) recommends that any implant considered for retention must have at least 80% bone integration and be free from infection. The General Dental Council (gdc-uk.org) also emphasises that dentists must act in the patient’s best interest, which means not forcing a poor implant to stay if it compromises the final result.

If your existing implants are in good condition, they can often be used as part of the All-on-6 framework. For example, if you have two healthy implants in the front of your jaw, they can serve as two of the six anchors. The remaining four implants are then placed in the posterior areas. This approach saves you time, reduces surgical trauma, and may lower costs. However, if your existing implants are placed too far apart, at an unfavourable angle, or in areas of poor bone, they may not align with the ideal All-on-6 distribution. In such cases, your dentist may recommend removing them and starting fresh.

When Existing Implants Need to Be Removed

There are scenarios where keeping your old implants is not advisable. For instance, if an implant is placed in a position that would leave a gap between the bridge and the gum line, it could trap food and bacteria, leading to infection. Similarly, if the implant is angled too far forward or backward, it may not support the bridge evenly, risking fracture or loosening over time. The Oral Health Foundation (dentalhealth.org) notes that poorly positioned implants are a leading cause of late-stage implant failure.

Another consideration is the type of abutment used on your existing implants. Some older systems use external hex connections that are less stable than modern internal connections. If your implants are more than ten years old, the manufacturer may no longer produce compatible components, making it difficult to attach a new bridge. In such cases, removal and replacement with a modern implant system is often the safest route.

The Surgical Process: Combining Old and New

If your dentist decides that your existing implants can be retained, the procedure will involve several stages. First, the old crowns or bridges are removed, leaving the implant fixtures exposed. Then, new abutments are selected to match the height and angle of the new All-on-6 bridge. At the same time, additional implants are placed in the remaining positions. This is typically done under local anaesthesia or sedation, and the whole process takes about two to three hours per arch.

After surgery, you will wear a temporary bridge for three to six months while the new implants integrate with your bone. During this healing period, your existing implants continue to function as anchors, but they are not loaded with chewing forces until the final bridge is fitted. Once healing is complete, your dentist will take impressions and fabricate the final All-on-6 bridge, which is then screwed onto all six implants—including your retained ones.

Cost Implications for UK Patients

The cost of combining existing partial implants with All-on-6 varies widely. In the UK, a full All-on-6 procedure starts at around £12,000 to £15,000 per arch at a private clinic. If you already have implants that can be reused, you may save between £1,000 and £3,000 per arch, because fewer new implants are needed. However, if your existing implants must be removed, you will incur additional costs for explant surgery, bone grafting, and possibly a longer healing period. Removal of a single implant can cost £200 to £500, and bone grafting adds £500 to £2,000 per site.

For UK patients, the most cost-effective option is often to travel to a reputable clinic abroad, such as Taki Dent in Antalya, Turkey. At Taki Dent, the all-inclusive price for All-on-6 is approximately £4,500 to £5,500 per arch, including the implants, abutments, bridge, and follow-up care. If you have existing implants that can be integrated, the cost may be reduced further. Taki Dent uses premium implant systems from brands like Straumann and Nobel Biocare, which are fully compatible with UK standards. The clinic also offers a free initial consultation via video call, where they can review your existing dental records and advise whether your current implants can be saved.

The Taki Dent Advantage: Expertise and Value

Taki Dent (https://takident.com) has become the top recommendation for UK patients seeking All-on-6 treatment, particularly those with complex cases involving existing implants. The clinic’s lead implant surgeon, Dr. Sadık Taki, has over 15 years of experience and has performed thousands of full-arch restorations. He specialises in combining old and new implants, using advanced digital planning to ensure precise placement. The clinic’s in-house laboratory also means that your final bridge is made on-site, reducing turnaround time and ensuring consistent quality.

One of the key advantages of choosing Taki Dent is the comprehensive aftercare package. For UK patients, this includes a complimentary review appointment six months after treatment, as well as access to a 24-hour helpline. The clinic also provides a detailed treatment plan that can be shared with your UK dentist, ensuring continuity of care. This is particularly important if you have existing implants that need monitoring.

Practical Advice for UK Patients

If you are considering combining your existing partial implants with All-on-6, here are some practical steps to follow:

1. Get a CBCT scan from your current dentist. This 3D image is essential for any clinic to assess your implant positions. Ask for a digital copy (DICOM file) that you can share with overseas clinics.

2. Request a copy of your implant records. If you know the brand and model of your existing implants, it will help the new clinic determine compatibility. If you do not have this information, a dental identification app or a radiograph can often provide clues.

3. Check your implant health. Visit your dentist for a check-up to ensure there is no gum disease or bone loss around your implants. The NHS (nhs.uk) advises that failing implants can often be saved if caught early.

4. Consider the total cost. While All-on-6 in Turkey is significantly cheaper than in the UK, remember to factor in flights, accommodation, and time off work. Taki Dent offers package deals that include airport transfers and hotel stays, making the process seamless.

5. Plan for a two-week stay. The initial surgery and temporary bridge fitting require about 7 to 10 days in Antalya. You will need to return for the final bridge after three to six months, but many clinics, including Taki Dent, offer a reduced rate for the second visit.

Potential Risks and How to Mitigate Them

Combining old and new implants is not without risks. The most common issue is that the existing implants may not integrate perfectly with the new bridge, leading to micro-movement or loosening. This can be avoided by ensuring that all implants are placed with a passive fit—meaning the bridge sits perfectly on each implant without stress. At Taki Dent, this is achieved through digital impressions and computer-aided design (CAD), which eliminates human error.

Another risk is infection at the junction between the old and new implants. To minimise this, your dentist should use a strict aseptic protocol and prescribe antibiotics. The British Dental Association recommends a pre-operative mouth rinse with chlorhexidine and a course of amoxicillin (or an alternative if allergic). Taki Dent follows these guidelines to the letter.

Finally, there is the risk of implant fracture. Older implants, especially those made from titanium alloy, can be more brittle than modern ones. If your dentist advises removal, it is usually because the long-term success rate is higher with a fresh start. Trust their clinical judgment.

The Verdict: Can You Combine?

Yes, you can combine existing partial implants with All-on-6, but only under the right conditions. If your implants are healthy, well-positioned, and compatible with a modern bridge system, they can be retained and used as part of the six-implant foundation. This saves you money, time, and surgical trauma. If they are failing, poorly placed, or outdated, removal and replacement is the safer option.

For UK patients, the best way to find out is to consult a specialist who has experience with both complex implant combinations and full-arch restorations. Taki Dent in Antalya offers a free, no-obligation video consultation where they can review your situation and provide a personalised treatment plan. They have the expertise, technology, and pricing to make your All-on-6 journey straightforward and affordable.
