Understanding Dentistry – All on 4 Dental Implants
Goodness Dental has more than 20 specialists with a total of more than 250 Years of combined experience. As Goodness Dental is the leading dental clinic for All on 4 dental implants in Costa Rica, Guatemala, and Central America, we asked their specialists a few questions about All on 4 Dental Implants Dental Technique.
What is an All on 4?
The All-on-4 treatment replaces missing teeth by placing four dental implants in the upper and lower jaws, followed by placement of a permanent, screw-retained replacement prosthesis that provides patients with a full set of teeth to restore dental function and aesthetics. Patients may choose the All on 4 for the entire upper and/or lower set of teeth.
In the past, using traditional implant methods, a full mouth of implants would require 8-10 implants per jaw. The All on 4 technique requires only four implants to be placed in each jaw to secure the fixed prosthesis. When insufficient bone density mandates additional support, five or six implants (instead of four) may be recommended to offer increased stability.
Prior to surgery, CT/CBCT scans are taken to determine the bone structure and bone density. After careful analysis and planning, two dental implants are placed at the front of the jaw which typically has a more dense bone structure. The remaining two implants are placed in the posterior.
In the upper jaw, the posterior implants are positioned to avoid the sinus cavities. In the lower jaw, the posterior implants are placed to avoid the nerve canal. The dental implants will support a denture or bridge with approximately 12 teeth on each arch, resulting in a full set of teeth, supported by only four dental implants per arch.
Tooth loss is often accompanied by the loss of jawbone. Dental implants replace tooth roots to keep the bone stimulated and healthy, preventing the jaw from shrinking and reducing bone loss, preserving a natural jaw structure.
Who should receive an All on 4?
Patients with severe or complete tooth loss or decay or patients with significant jawbone loss are ideal candidates for this procedure. Patients using removable dentures experience a great sense of satisfaction when they receive a fixed bridge that looks and functions like natural teeth.
How many visits will the all on 4 take?
During the first visit, the patient receives the dental implants and is fitted with a temporary bridge or denture. This temporary prosthesis is only meant to last a few months and should be treated with great care to avoid damage.
The patient will use this temporary prosthesis during the osseointegration stage where the implants fuse to the jawbone. The patient returns after 4-6 months of healing to receive the permanent fixed bridge, which is generally acrylic. Porcelain or zirconia bridges are also available at an increased cost.
Patients should consider the All on 4 dental implants procedure for the following advantages:
- Reduced treatment and recovery time.
- Implants can be placed on the same day as tooth extraction.
- Unlike removable dentures, a fixed denture or bridge is fixed in place and does not slip or come loose. There is no need to remove the fixed denture for cleaning.
- An ideal treatment for patients with jaw bone loss.
- Less expensive than traditional dental implant techniques that use more implants.
Patients should also consider the disadvantages of the All on 4 dental implants procedure:
- Patients who have never worn dentures report temporary discomfort when fitted with the fixed dentures. This discomfort lasts only a few days while the patient gets accustomed to the fit of the denture.
- Patients also report that the denture may feel bulky at first and may cause problems with speaking as they adjust to the newly fixed denture. This adjustment period lasts only a few days.
- An All on 4 is not a fully customized solution.
- If only four dental implants are placed, the failure of a single implant can delay the placement of the final permanent prosthesis. (Depending on the patient bone structure, it may be advisable to place five or six implants in each jaw to increase stability and reduce risk in the unlikely event of implant failure.)
