If the Implants That Support an All-on-four Fail, What Are the Treatment Options?

There are several things to keep in mind as you try to gauge how successful that your All On Four procedure will be. Here is a list of things to consider:

1. Smoking and drinking alcohol does increase the chance that you could have one or more implants fail. You may not have any problems at all, but certainly need to be aware that this could happen.  

2.  It would be wise to choose a surgeon that will utilize a 3D CBCT (CT Scan) in planning your case to ensure that the dental implants can be positioned appropriately and placed where the bone quantity is good.  If the bone is not of good quantity, then a bone grafting procedure may be required prior to placement of the implants.  

3.  If the implants are spaced evenly it will be easier to keep the occlusal (chewing) forces equal on all implants.  You have a higher percentage rate of an implant failing if it is placed under more stress than the others.  

4.  Should you have an implant fail it does not mean that the others will fail.  If one fails a bone grafting procedure can be performed and a new implant placed at a later date. 

5.  Follow all pre-op and post-op instructions that your surgeon gives you to ensure optimal healing from your surgery.  

First of all you need to discuss with the doctor ehat are the warranty conditions,because they change depending on the doctor,if the doctor is ethical and professional he will explain and give you the options if dental implants are rejected,how many times the doctor will re do the proceedure and under which conditions,also discuss the economic part including sedations and prosthetic replacement.

I am not a fan of all on four precisely because of that problem but I have referred several patients to clear choice and seen excellent results.

 

The majority of my patients have snap-in restorations on 4 implants.  They feel like fixed resorations but are much easier for patients to care for.  Loss of a single implant temporarily decreases stability slightly but is easy to add back an implant.  If all on four loses a key implant it can be converted to a snap in prosthesis.  

I usually utilize 4 implants with four mini implants which are loaded immediately while the larger implants are left undisturbed during healing.  The minis  usually remain when the primary implants are loaded giving emergeny back-up if ever needed.

An interim prothesis that looks and feels great is then used as a template for the final work.  I find that a high-end esthetic result for the patient is important versus the one size fits all teeth in a day approach.  Should the patient decide on fixed work they have an opportunity to try out their new smile prior to finalization
