The all-on-four on dental treatment was introduced to minimize the amount of implants needed to restore a full arch dentition. The all on four system enables a bridge or denture to be fitted the same day as the implants are placed. This is due to where the implants are placed in the jaw, the angle at which they are placed and the bracing method used for the bridge or denture which, then allows forces of the bite to be loaded evenly through the implants to the bone.
Traditional implant restoration of a full arch would require six to ten dental implants, increasing the cost of treatment for the patient. There is also a longer period of healing before the patient can have the implants restored with a bridge or denture.
Most dental patients that require restoration of a full arch dentition are suitable for the all on four method of treatment. However, there are exceptions, those that have server periodontal disease (gum disease), smokers, and those taking certain medications for bone density.
All patients looking to have all on four treatments must go through a thorough examination and consultation before any treatment method can be advised. On occasion it is advisable that patients have CT scan to check availability of bone and it’s quality within the jaw.
The advantages for having all on four treatment for patients is that treatment time is minimised within the dental surgery due to the effectiveness of this method and that patients can have implants placed and restored in one appointment.
