All-on-4® dental implants are a game-changing solution for people with tooth or bone loss. Through only four implants in each jawbone, your smile and oral function can be restored with this dental treatment.
However, like any medical procedure, the All-on-4® treatment can have potential issues. If you’re thinking about getting All-on-4® dental implants, it’s essential to understand the associated risks and complications.
This article will explore the potential risks and complications associated with All-on-4® surgery and recovery and the best way to avoid them to ensure you’re left with a healthy, radiant smile.
Pioneered by Dr Paulo Malo, All-on-4® is a dental restoration solution that offers a long-term, fixed alternative to dentures.
It works by replacing an arch of teeth supported on only four implants in either the upper or lower jawbone. When you undergo the All-on-4® treatment at Next Smile Australia, it happens in two stages.
Stage one involves your surgery, where you have the four dental implants surgically placed and receive a provisional bridge that you wear for three to six months while your bone fuses with dental implants. You usually receive your temporary teeth within the same day of surgery or 24 hours.
Stage two of the process involves you being fitted with your final set of teeth.
So, how successful is All-on-4®? Compared to older dental treatment methods, All-on-4® not only reduces the number of dental implants required but has a proven success rate of 98%*. So, you can have peace of mind knowing the All-on-4® dental implant risks and complications are less than 3%.
Although All-on-4® has a 98% success rate, like any surgical procedure there are some potential risks to be aware of.
Nerve Damage: The lower jaw contains important nerves that must be carefully avoided during implant placement. If a nerve is affected, symptoms such as tingling, numbness or pain in the lower lip or chin may occur. While nerve damage is rare (around 1% of dental surgeries), the risk can be higher with All-on-4® due to implant positioning. Choosing an experienced All-on-4® surgeon and using advanced 3D imaging significantly reduces this risk. At Next Smile Australia, all patients undergo detailed 3D scans prior to surgery.
Sinus Issues: For upper arch All-on-4® treatment, implants placed too close to the sinus cavity can cause complications. Although uncommon, this may require additional treatment. Pre-surgical 3D planning and experienced surgical placement greatly minimise this risk.
Gum Colour Mismatch: All-on-4® prosthetics are designed to closely match your natural gum tissue. In rare cases, the colour may not be an exact match and the bridge may need refinishing or replacement to achieve the desired aesthetic.
Bite Misalignment: If implants are not positioned precisely, bite imbalance can occur, potentially leading to jaw discomfort or TMJ issues. Accurate planning and careful post-surgical alignment are essential to prevent this.
All-on-4® dental implant risks aren’t limited to surgery. Some complications can also occur during the recovery period.
Mouth Infection: While infection is uncommon, it can occur after All-on-4® surgery due to the number of implants placed and their depth within the gum tissue. The risk increases if post-operative care instructions aren’t followed or if you smoke or vape. Symptoms may include pain, swelling and persistent bad breath. Maintaining good oral hygiene and following your surgeon’s aftercare guidance is key to reducing this risk.
Dental Implant Failure: Although All-on-4® has a 98% success rate, implant failure is still possible. The most common cause is poor osseointegration, where the implant doesn’t properly fuse with the jawbone. Factors such as bone loss, infection, smoking, uncontrolled diabetes or poor treatment planning can increase this risk. Avoiding smoking and alcohol and closely following aftercare instructions helps support successful healing.
Gum Infection or Disease: Bacteria can sometimes enter the gum tissue surrounding the implants, leading to inflammation or infection. Daily brushing and flossing, along with regular six-monthly hygiene appointments and check-ups, are essential to maintaining healthy gums after All-on-4® treatment.
While there are few All-on-4® dental implant risks and complications, they could still happen to you. So, what’s the best way to avoid those risks and complications?
Maintain Good Oral Hygiene: One of the best ways to avoid dental implant complications with All-on-4® is to maintain good oral hygiene.
Regular brushing, flossing and routine dental check-ups will help reduce the chance of infection and other possible complications.
Choose an Experienced All-on-4® Dental Surgeon: Choosing an All-on-4® dental surgeon with many years of experience, such as those at Next Smile Australia, can minimise the chance of issues arising from poor treatment planning or implant misplacement.
Follow a Healthy Diet: Eating nutrient-rich food and avoiding hard, crunchy foods can help maintain bone health and promote healing after All-on-4® surgery. It’s particularly important to eat soft foods during the initial recovery period to not damage your new teeth or disrupt the healing process.
