Broken All On 4 Dental Implant Bridges

Broken All On 4 Dental Implant Bridges

Broken All On 4 Dental Implant Bridges


I have been seeing a rise in complications on patients who have had the ALL ON 4 dental implant procedure.  Many patients end up in my office for redo treatment after things have gone very wrong.  I’m seeing a lot of broken bridges and bone loss recall peri-implantitis.  In this video I will discuss what to do to prevent and deal with this complication.

Below are some pictures of broken bridges.

Your comments and questions are welcome.

    I have full set on 4 posts on both top and bottom . I got them last year and they have fractured at the post 4 times , three times in the same spot in the back bottom and one in the front on the top. I wasn’t eating anything major, chips, enchiladas, nothing too hard

      Are they zirconia or still acrylic?

    I am a 35 year old female who has had the all on 4 procedure done a little over 2 years ago and I have unfortunately had 7 procedures on my upper jaw due to lack of bone and failed implants or cracked off bridges and implant replacement. with health issues that sometime prevent my body from working properly what would really be a solution to this problem? and furthermore since a bridge or denture is my future if i want to eat food, how can i suggest to my dentist how to make bridges for me so that pieces stop chipping off of them?

      I am guessing this is an upper and not a lower. Also guessing you have acrylic hybrids and not a premium zirconia.

      It sounds like you “may” be better of with zygomatic implants or full lateral window sinus grafts.

      Zirconia teeth when made right don’t chip..ever

      If the teeth keep breaking it’s because they made out of acrylic. This is basically a glorified plastic wrapped over metal often referred to as a hybrid. Would be better off replacing the bridge to a more durable premium material like zirconia.

    Subject: Snap in denture

    I also have the snap in on the bottom. Two snaps placed on the bottom front. (around or about 11 & 1 o’clock) This procedure was started around the first week in March, 2017.

    I loved them at first! The first time I could actually eat with them, food went immediately underneath them. I still loved them though. I was told that would be corrected. (Has not been corrected to date) And not noted in my file.

    After a couple of weeks they started lifting. I could easily pop them out with my tongue. I immediately called my dentist. This was on a Friday. He told me that wasn’t suppose to happen and NOT to eat with them and wear them only when I must. It could damage them and/or the post (implants) and to be at his office on Monday morning. He died in a terrible accident that same Friday afternoon, in April.

    A month or so later his wife/office manager sent me to another dentist, about 70 miles from here, to check them and adjust the bite. Thanked me for being so patient and she would soon have someone in to pick up/take over the practice.

    The dentist she sent me to did a wonderful job on the bite adjustment. Unfortunately, he doesn’t do the same type of implants. He only does mini implants. He told me to use cream to fill in because they were loose fitting. I was VERY careful not to eat with them.

    Eventually another dentist came into his practice to take over/buy it. He told me I could eat with them. Now, after going through every color of the little inserts that go into the holes in the denture to keep them securely in place and therefore adjusting the bite each time, the back teeth are now flat causing me to grind food instead of chewing and still will not stay snapped in.
    They are so loose fitting now that it rises up and off the post causing the post to hit the denture when eating. On top of that one of his assistants took too much off one side of the upper and now it doesn’t have suction to hold it in place.

    The new dentist sent me to someone else, dentist/oral surgeon before Christmas, to look at the problem. He wants to do a special dental cat scan, starting at around $400.00. I can’t afford that right now. Plus he told me the post weren’t placed in the correct place. It took until mid January for the two dentist to actually talk about my unique situation. The new/old dentist finally tells me he can’t do anything until I have the scan done by the new dentist /oral surgeon which I cannot afford right now. And to be careful eating.

    If I don’t keep my tongue on them while practicing yoga, they will fall out.
    They did fall out last night and broke in half. Called this morning and was told to come in and they would see if they could fix them if not I would have to purchase new ones.

    It cost me $125.00 to have the bottom repaired. I also found out the “new” dentist is not fixing the problem without being paid. More than $2600.00 to make a new bottom that may fit properly.

    Had the Cone Beam Scan done. The oral surgeon that did it says one of the implants is slightly leaning. I already knew this. I can feel it. That is why the gum stays irritated at the base of the post. He says the 2 post I have is not enough. I need 4. That’s $4000.00 more. He also told me he would never do just 2 for someone my age. It simply will not work. If I were 90 and just wanted them for church he would agree. He told me this the first time I saw him also.

    The bottom broke again! I was eating a slice of pizza. One tooth is missing at the break line, yeah I must have swallowed it, and will now cost me $200.00 to repair. That’s with a $50.00 discount. I was told they will break again. The person in the practice that makes the dentures said mine were wore out and I needed new ones! These aren’t even a year old yet!!!!

    Now the dentist, that took over the practice, is telling me I happen to be one of those people that need 4. Until I do that…. he just shrugged.

    I am at my wits end.

      yikes…..The best advice your given was by the surgeon that said 2 implants is not enough. You likely have very severe bone loss and only 2 implants still create a severe rock and a fulcrum point. I don’t think I would spend any more money trying to get them to hold in place because it sounds like your case was under engineered to begin with. If I were to have seen you as a new patient and you told me all you could afford was 2 implants I would steer you away from having dental implants whatsoever because the benefit would be minimal. Ideally you get rid of the denture altogether and go to a fixed, nonremovable bridge. Obviously this is more costly but you are quality of life will increase tremendously.

    I had the all on 4 procedure 10 months ago. The front left tooth snapped completely off 5 weeks ago whilst eating. It came away whole and slots back into place. It is being fixed next week. Is this normal?

      Most All on 4’s are very weak. I would suggest you upgrade to Prettau Zirconia and ideally add more implants unless they are zygomatic implants.

    I had the last 11 teeth taken out 1/14/16, had a DMD make me the first set of dentures which NEVER fit even after several re linings. After 8 months he told me the next set would fit about the same. I had a reaction to the lining; soft lining and was NEVER ABLE TO ADUST. I could not afford implants. So I learned to use a soft lining and still was never able to chew with them so they became cosmetic in nature. Dealing with a back injury and going from dentist to dentist I finally agreed to have two implants put in the bottom front. I have almost no ridge of the bottom and received the dentures; very hard and they immediately put pressure on the nerve in lower inside ridge on right side. So here I am again!! I have two implants sitting under the gum and they are anxious to complete the bottom with bar an screws but I don’t see the logic in doing this until I am able to wear these without pain!! They insist that they don’t do soft linings; although there are many permanent soft linings now available.. In your opinion do you know of one that would work with the two implants? I am facing reconstructive surgery on back and need to figure this out. I would so appreciate any help here..

      If your bone is truly very thin then two implants are not going to help that much. A minimum of four implants would be much better to distribute the load and spread out the pressure more evenly.

      What counts the most is how the lower overdenture fits well the implants are attached not just by itself. Most of the time, when done correctly these are bulletproof for many years. I hope everything works out for you. I hear your frustration.

There aren't enough words (and I have a lot of words) to tell you how grateful I am to have found Dr. Ramsey Amin and his wonderful staff. I had an enormous amount of bone loss and I was hopeless after being treated by a different doctor for two years. I had multiple procedures such as gum graft, extractions, and a sinus lift. After all of that, the doctor released me and told me he could not help me any longer. He sent me to a large teaching hospital - who also had no idea how to help me. I was terrified and embarrassed. I had been missing teeth due to those procedures since 2017. That sent me out on a journey of meeting with no less than five different dentist/oral surgeons. Most of them shamed me for the bone loss and wondered what I had done to cause this. In reality, I had done nothing. The bone loss is my body's immune system fighting me, as well as hereditary traits. In fact not only was I having difficulty being able to have implants, I also had so much bone loss that I was also not a candidate for dentures. I researched "what to do when you have bone loss and can't get implants" and I found Dr. Amin's website. Then I researched him, read his reviews, watched every one of his You Tube videos. I called and got an appointment, and kept going to consultations with other providers. I had long since stopped smiling and being social. Missing teeth and the shaming was affecting my life so adversely. When I met with Dr. Amin for my consultation he was ready. He had all of my records and had already reviewed my scans. But more than that, he genuinely wanted to get to know about my life. He was/is authentic, kind and extremely professional with so much success and experience in difficult cases like mine. He worked up a treatment plan & I came back two weeks later to discuss my options...and the journey began. I have had three procedures under IV sedation, no pain, no narcotics needed for aftercare. Dr. Amin is a consumate, experienced oral surgeon who cares about your health & understands your fears. He communicates every step of the way and will provide you with all the information you need to make a decision to improve your health. I am still working toward my end goal, and we had to zig from traditional implants and zag to zygomatic implants instead...which is the reason I chose him in the first place. If there was nothing else that could be done to get me healthy & smiling again, I knew he would have that option to help me. And of course 2020, the year of CV-19. Don't worry, Dr. Amin & his staff follow all health & safety protocols. This review is long, because it is important you know my journey, so you might understand how fortunate I feel to be healing. I'm torn, because this place is like a great restaurant, I want to shout from the rooftops how great it is, how great he is. And at the same time, I want to keep this all to myself. I come 75 miles each way to see him. I know people travel from all over the world for his expertise. Do yourself a favor, have a consultation. You won't regret it. Dr. Amin is amazing and so is his staff.

I cannot speak highly enough of Dr. Amin and his professional staff. I have to start off and say that I am absolutely TERRIFIED of the dentist due to several past experiences. I found myself putting this off for YEARS until I was referred over to Dr. Amin. I was petrified on my first visit... but he along with his WONDERFUL staff made me feel so calm and at ease. I had quite a bit of work that needed to be done, but we found the perfect plan that worked out for me, and I couldn't be happier. Words cannot express my gratitude to each and every staff member that made me feel safe and comfortable. Dr. Amin was always so attentive in asking if I was ever in pain... and I never was. These are truly remarkable individuals, and I'm so lucky to have a dentist that I can trust. I ABSOLUTELY LOVE each and every one of you! Thank you,

I cannot say enough positive things about Dr. Amin and his staff. I originally found them on Yelp about two years ago. I needed an implant, front tooth of all places, and was extremely nervous not only about surgery but about how it would turn out. Let me just say I just adore the staff. Everyone is crazy friendly and the whole office has a very positive vibe. The staff is adorable and always has me smiling by the time I leave. They are all thorough and on-point about what they do, and I truly appreciate it. They are quick to respond to my emails no matter the question, and their appointment reminders are great too. Dr. Amin is very thorough and reassuring, and answered any questions my husband or I had. My regular dentist had questions about the procedure and Dr. Amin's office even reached out to them at my request (my dentist said they never received a call, but Dr. Amin's staff had date, time and notes - love the thoroughness!). After surgery the Dr. called to leave me a message about how it went. Very minimal pain during healing, never any pain during any visits. It took a few tries to get everything just right for the permanent crown (color, etc), but the end result is beyond fantastic! At one point during healing I thought I was experiencing some looseness or wiggling but unfortunately couldn't make it to the office. When I was finally able to make it in the Dr. was so relieved, bless his heart. Luckily it was just a false alarm and everything checked out ok. They're a bit further out from me, but I wanted the best. I sure found it! I wish they were my regular dentist, and I'm looking forward to seeing them again for my check-up which was delayed due to COVID.

I found Dr. Amin a few years back after I hadn't been to a dentist in a decade. Many traumatic dental experiences in childhood have made me so phobic that even getting a cleaning was a knee-knocking, heart-pounding trial. But finally I couldn't put off some things any longer. During my first anesthesia session, Dr. Amin replaced five old metal fillings, and during the second he did three more plus a crown. I was completely comfortable, and never felt a thing. Because they were extra-long sessions, I did sleep for about 12 hours after, but the next day I felt just fine. This past week, my back top tooth cracked in half and fell out of my mouth, and a couple days later the crown on the remainder of the tooth fell out too! Despite being nervous about Covid 19, I had to get it taken care of, so I called and quizzed the staff about precautions, which turned out to be even above and beyond what I would have expected. So yesterday I went for the tooth extraction and plug. After they put on the blood pressure cuff and put in the IV, I gradually got a little tired and closed my eyes. I sat there for about 10 minutes and thought Gee, I wonder if they're going to get started any time soon, and a minute later Dr. Amin said "Wake up, you're all done!" That was a short session, and I didn't have the kind of fatigue I did my first time. I stayed up most of the evening. Today, everything is good! I'm taking my antibiotic and eating soft foods, and there is surprisingly little pain now that the numbness has worn off. The tooth site and my cheek are a little sore, and the corner of my mouth, and I have a very slight headache, but nothing to any great level--I'm not even taking the acetaminophen. I feel good, and wide awake. Thanks to everyone at the office for a comfortable and professional job! I really REALLY appreciate you for giving me painless dental experiences!

What can I say about Dr. Amin he is the best! I'm so grateful for him. He has literally changed my life and given me the confidence to smile more. I had major restorative dental work done and everything went smoothly. Dr. Amin is very compassionate and he really cares about his patients he made me feel comfortable and cared for. He is very knowledgeable and has a great sense of humor. His office is very clean and they take the patients health and safety very serious. His staff is also amazing they made me feel very welcomed and important. I'm so happy I did my research and found Dr. Amin.  Thank you Dr. Amin and team.

Two implants done! Finished all procedures and I couldn't be happier. It's the first time in years I looked forward to going to the dentist. Even during Covid life the staff and Dr. Amin took care of me. There is a possibility I may move to Long Beach but I would still travel to keep Dr. Amin as my dentist.

I could not ask for a more caring, exceptionally knowledgeable dental care provider. He's not just a dentist, but someone who looks after your immediate dental needs and helps you plan and prepare for the future.

I've been going to Dr. Amin since I turned 16 and have been going since. Before going to Dr. Amin's dental office, I had 4 crowns that I was not happy with and dealt with it until finally I asked Dr. Amin and because I  feel comfortable and because I trust him with his work I recently had my crowns fixed and worked on by  Dr. Amin and have never loved my smile the way I do now, I can actually enjoy my pictures, I can enjoy my smile from either angle and that really mattered to me. Thank you so much Dr. Amin still and will be in love with MY smile

I've been coming to Dr. Ramsey for about five years and I have to say, he is by far the best dentist I've had - ever. The staff is professional and kind, the office is exceptionally well maintained, and Dr. Ramsey is careful and extremely knowledgeable about current developments and research in dentistry. I recently had a dental implant which was a long process but well worth it. I required a sinus lift as well as a bone graft. The surgery went off without a hitch, I was comfortable and the healing process was quick and without complication. Highly recommend!!

This is my 1st review of Dr. Amin, and in my over 17 years of being with him, my experiences with Dr. Amin and his staff have always been positive.  I don't recall a bad experience with the several implant procedures i have had.  They run an efficient office.  I like that they are proactive and reach out to their patients to remind us of routine care needed.  Dr. Amin's bedside care is impeccable.  They are also technologically up to date in terms of sending out texts as reminders, ability to incorporate any appointment into your mobile phone.  That is certainly a plus.  Keep up the great care!!!
