The All-on 4 treatment concept was first put into practice in 1998 as a way to restore the full arches of the upper and lower jaws. The term ‘All-on-4’ refers to all teeth being supported on four dental implants.
If you are eligible for All-on-4 treatment, your journey is usually complete in two stages. The first stage involves an oral evaluation, assessment of your dental needs and a 3D CT scan to assess your jawbone health. This is followed by impression taking, so the prosthetic dental bridge (set of teeth) can be created. Your custom design is created at a dental laboratory.
The second stage of your treatment is the surgery, during which the implants are placed. Four implants can be used to support the fixed prosthesis with 12 to 14 teeth. Two dental implants are placed near the front of your jaw and another two are placed at a 45-degree angle nearer to the back of the jaw. This position of the two posterior implants increases bone-to-implant contact and allows the implants to be anchored in better quality bone.
The specialist will then attach your new set of (temporary) teeth and adjust it for comfort. You will need to leave three to six months for your implants to heal, ready for your final dental bridge.
The healing process allows the bone to bond to the implant, known in dental terms as ‘osseointegration’.
Advantages of All-on-4
