Concerns about complications from All-on-6 implants

Question

I want to have All on Six upper and lower. My friend had hers done a month ago, and her acrylic temporary arches keep breaking. The very 'reputable' surgeon also doesn't appear to be correcting her overbite, which he said he could. In fact, her temporary bridges are both protruding, and she has a hard time talking/chewing. Is this all a normal part of the process for this procedure???? After seeing her nightmare, I'm worried.

Unfortunately fracture of the temporary or interim prosthetic is a known and realistic complication. It is more common when the patient has a history of bruxism, clenching, grinding. We ask patient to remain on a very soft diet during the healing phase which helps protect them from fracturing the temporary. 
The second concern of an overbite seems to be one of skeletal concern. If there is a true underlying skeletal cause of an overbite or underbite this can not easily be fixed with prosthetics alone, in some cases jaw surgery is warranted. You may be able to slightly improve and underbite or overbite with prosthetics if minor or only dental in nature

Hello. Temporary acrylic prostheses are softer materials than permanent prosthesis materials such as zirconia or porcelain fused metal.
There are several possible reasons of temporary prosthesis breakage. The most important possible cause is bruxism which may cause failure of implants besides fractures of prosthesis. So, masseter botox in early healing phase of All-on-4 can be helpful to decrease occlusal forces. 
Acrylic prosthesis may also break due to inadequate lab work. 
This breakage is an early warning against heavy occlusal load to protect implants in a way. 
Overbite can be corrected by correcting the vertical dimension and set of teeth in try in sessions.

Hi, It is possible for the initial acrylic to sometimes break. It is a temporary measure but usually they don't. I would request a PMMA or an acrylic version made prior to the final to make sure the teeth and bite is aligned and looks great then I would sign off on them making the final which should be significantly improved.

Hello, without photos and seeing your friend it is impossible to answer your question. However, with properly placed implants and a good prosthetic dentist who will be making the teeth fitting over the implants, there is no reason you should not get a good result. 
Seeing you or your friend can certainly allow me to provide definitive answers.

There are many providers to choose from for All on Four treatment (All on Six in this case), and there are many methods. Most clinicians end up at the same result, but not always. Even if the result is the same, the experience can vary tremendously, even with the same provider. The challenges/complications your friend has doesn't mean you will have the same things happen to you.

Having said that, it is very important to find a good clinician.

There are two procedures that can provide a solution for missing teeth: Snap-in dentures and the All-on-4 implant technique.
Snap-in dentures use eight narrow implants, four on the upper jaw and four on the lower jaw, to support a removable denture. This can be a life-changing solution for those with missing teeth.
The All-on-4 technique uses a screw-retained bar connected to four implants that are strategically placed in the jaw. Two of the implants are tilted and two are placed straight to maximize support and stability. This provides a strong and cosmetic solution for missing teeth.
Before undergoing either procedure, a clinical and X-ray diagnosis should be performed to determine the best course of action for each patient's unique needs. It's important to choose an experienced All-on-4 specialist who can provide the best results.
It's also important to note that while the shape, size, and color of replacement teeth can be customized, the overall success of the procedure depends on factors such as jawbone density, oral health, and lifestyle habits. With proper care and maintenance, both Snap-in dentures and the All-on-4 technique can provide long-lasting, effective solutions for missing teeth.
