Replace Loose Long Bridge -Dental Implants And Bone Expansion

This Burbank patient had a loose lower bridge.  She had had the bridge for about only 8 years before it failed and became loose.  You know a bridge is failing when it feels painful to bite down or there is movement.  This unfortunately is a daily thing I see every day.  Teeth were never intended to be hooked to other teeth.  She came to me because she wants dental implants to replace the bridge.

The existing lower bridge was made with a metal biting surface because the patient has a VERY  strong bite.  She wanted to make sure that her new dental implants could withstand her bite force.  She has broken other bridges in the past. You can see in her photos that she has worn through some of the porcelain showing through to the old metal layer on the opposite side next to the yellow gold crown.

What is under a broken bridge:

When I removed the bridge I found one of the teeth anchors broken.   That broken root canal tooth is not savable and will need to be extracted. The back wisdom anchor tooth is healthy in and of itself but is tilted towards the front.  This patient is unique in that she has very long roots as shown on her panoramic x-rays.

The biggest issue is that the bone in the area where the teeth used to be is super thin.  When you lose a tooth or a segment of teeth, the bone thins out because it is not being used.  This process is called atrophy (BONE LOSS) .  So even though her bone was tall enough, it was not wide enough to have implants properly placed in the center of where the teeth used to be.  If you try to have your implants done without a bone graft, the implants would have to be pushed towards your tongue side and the implants would be a very small diameter with minimal bone on the outer wall… a recipe for disaster.

Replace Bridge with Implants 

In her case, I did a bone widening/expansion ridge split.  In this process, I actually purposely “break” the outer layer of bone towards the outside and push the outer layer of bone away from the inner layer of bone.  This creates a big trough which can then be filled with donor cadaver/cow bone and L PRF/PRP made from your own blood.   This is a very advanced bone grafting technique that is not just a typical mild expansion of bone.  It is a full repositioning of the outer wall of the lower jaw bone.

This bone graft was allowed to heal for 4-6 months prior to placing the implants.  In her case I would not advise placing implants at the same time of the bone graft although in many cases I do place the implant simultaneously.  Her case was special and that she was on a bisphosphonate medication in the past for cancer treatment.  The bisphosphonate medications can slow down bone healing and can have really detrimental complications so going slow was better than going fast.  I did some blood tests for her and also consulted with her physician prior to initiating treatment.  It is always best to be safe especially when dealing with dental implants and medications similar to Boniva and Fosamax.

After a few months of healing I decided to place 3 dental implants for a connected-splinted dental implant bridge.  Remember she wants the “strongest possible” solution so I advised her to have 3 implants and a 3 tooth bridge rather than 2 implants and a 3 tooth bridge.  Connecting the teeth is definitely the strongest way and helps prevent food impaction.

In the photographs, you can see how wide the bone is and how the implants are well centered and spaced now that she has the proper amount of bone.  The implants are long and of a really good diameter for a proper emergence from the gums for large molar teeth.

After 3 months of healing, I began to take my initial 3-D video scans of her mouth to fabricate her teeth.  I made 3 titanium abutments on the 3-D printed model in a virtual program.  This way the teeth are fabricated using a computer and not typical gypsum clay molds and messy impression material that gets stuck in your mouth!

The abutments were steam cleaned and sandblasted for proper cement hold and sterility.  This is a another important step which is commonly skipped.  The implant abutment junction must be super clean and the smooth metal must be roughened slightly for micro retention.

The implant bridge was then fabricated using monolithic zirconia.  This material is wonderful because it is white, strong and aesthetic for back teeth.  It is stronger than original bridge with the metal support.  I use this material quite commonly for my full mouth Prettau zirconia dental implant bridges.

Needless to say, she was very happy with the final result of her teeth. I am sure they will last a very long time. The best part was the big hug she gave me at the end.

    Dear Dr. Ramsey! You have amazing talent at what you do! Is it normal to have face pain everywhere top, sides,stomach cramping, neck pain, tightness around your eyes, and constant throbbing after lower bone grafts? I had right &l left lower bone grafts with calcium phosphate injection under my bone area where the bone loss was from prior broken and missing 3 molars on both sides. The swelling is no doubt normal and to be expected, but the rest of my face constantly hurts and throbs with vision blurry from pressure working it’s way up from the lower bone grafts areas where it was done. It even weakens my legs when standing from the face pressure causing vertigo! Pressure in my ears to. Is this normal after my bone grafts in the both sides lower area’s? And is calcium phosphate a good choice of synthetic graft material used to stimulate my bone to grow in for future implants?

      All that pain you are describing is not normal summation point I am not a big fan of calcium phosphate. Synthetic bone materials did not perform well especially for any substantial type of grafting. They do not contain any real bone cells. There is a lot of hype and misinformation about them but hopefully it works for you… Fingers crossed. I think you should see your dentist and certainly be on an antibiotic.

    Hi Dr Amin,

    I have been a regular reader of your blog as a prospective implant-candidate and I must say the information on your blog and your YouTube channel is amazing. It has certainly informed and educated me on various aspect of implant in particular and oral care in general. My grateful thanks to you.

    My case if that I have had a three unit bridge from my premolar to the second molar on the lower left. The bridge lasted 11 years although the second molar had a deep filling when the bridge was done. Three years ago an RCT was done; now the the RCT has failed, the bridge removed and my implant surgeon says the second molar and the slightly bent wisdom tooth next to it have to be extracted and implants put in. My question is he’s suggesting RCT-ing the healthy premolar as it will go next to the implant so as to prevent any future complications. I want to save my natural tooth with a crown. It’d be helpful if you could tell me if my efforts to save the tooth with a crown is the way to go.

    Thanks a lot for reading my query.

      Thank you for your kind words… Why not just have a crown without the root canal? A root canal weakens the tooth. If the tooth is not dead there really is no reason to do a root canal “just in case.”

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!!!
