Understanding the Differences Between All-on-Four Implants & Dentures
If you have lost all your teeth due to an accident or a widespread decay issue, then you may not be too happy about the thought of dentures. While traditional dentures are a good option for some, you may want a more permanent and natural look reconstruction. This means that you need to work with a dentist who is experienced in full mouth reconstruction. The professional may suggest that dental implants are secured, and a process called all on four implantation may be suggested.
Keep reading to understand exactly what this is and why it is different than receiving dentures.
What Are All-on-Four Implants?
All-on-four dental implants are a type of full-arch reconstruction where an artificial dental arch is constructed to connect to four dental implants. This means that the entire artificial structure across the bottom of the jaw will fit on four implant roots, and the top arch will connect to four separate implants as well. In total, eight implant roots are secured to completely restore dental function.
The implants are spaced out along the jaw to hold the arch in a secure and healthy manner. Two implants will sit towards the front of the mouth and two will be secure back further along the side or the back of the jaw. The front implant roots will sit straight up into the mouth at a 90 degree angle to the jaw. The back implants will be fitted at a 45 degree angle. This is the case to help spread out the stress and pressure more evenly across the bone, especially since the back teeth place more stress on the jaw.
How Are the Implants Different from Dentures?
Dentures do involve the replacement of the top and bottom arch. However, the artificial teeth are loose. While fixed dentures can be created, they can still be removed by unsnapping or angling them off the attachments. This is not the case for all on four implants. The implants are constructed more like bridges than dentures. Also, unlike dentures, you will likely need a porcelain prosthetic instead of an acrylic one. Specific molds and dimensions will also be needed to construct the reconstructions so they very closely mimic the shape, size, and appearance of your former natural teeth.
Once the arches are made, they are attached to the dental implant roots with the help of screw on devices that sit inside on the bridge. The screws can only be removed by your dentist id a repair of replacement needs to be made.
