In the last 11 years of placing dental implants in Los Angeles I have only ever had to remove a broken screw on old implants placed 25-30 years ago. Dental implant abutment screws really don’t break anymore!
They used to break when cheap dental implants were used that had an “external hex” as opposed to an “internal connection.” A dental implant is a screw within a screw. The implant itself looks like a screw and then the implant abutment usually connects to the implant by a screw. These screws are about 1.25mm with an allen hex on the end, and they are made of medical-grade titanium. It is the silver one in the picture. The green piece is not relevant.
Internal connection implants like I use take the force off the screw and place it on the connection or deeper in the implant. The main reason for a screw to loosen or break on a well- placed implant is excessive bite force on the implant. Keep in mind that your bite changes over time on your implant and that it can become excessive over time.
Other reasons a screw can loosen or break are: poor quality implant, rounding out the connection by excessive force of placement, poorly casted screw seat in a screw-retained crown, or an abutment that didn’t get torqued properly.
The x-ray shows the broken screw still inside this implant. That tiny piece is not easy to get out as it needs to be backed out about seven revolutions. It is like trying to take out an eyeglass screw and the Phillips head is broken off.
Careful technique, patience, and a slow drill in reverse can grab the screw out. Most dentists that are involved in implants have never done this.
This case happens to be an implant held in by a screw with a metal biting surface rather than a traditional white cemented crown. Many dentists often resort to extracting the entire implant over a broken screw…yikes!

Hi a while back I went to a dentist cause I knocked out two teeth. She told me all my upper teeth have fractures and I should consider replacing all my upper teeth with implants. Was not cheep but I did. I paid $21,000 out of $28,000. Due to COVID-19 I had to move and can’t afford to pay the remainder of the balance.my issue is I still have the temperary implants in. How long do they last
Oh gosh. The temps usually begin to fall apart at about 1 year. What material were the finals going to be made of?
I had a three tooth bridge replaced by a three tooth implant bridge.
Two implants and a three tooth crown. It took three different impressions and crowns before the third finally seated. The doctor put the rear abutment screw in, then the front and it broke. After several attempts he finally got the screw out. After celebrating, high fives etc. he put the front screw in no problem. Then put the rear screw in and now it broke. He has not attempted removal yet.
It was torqued to spec. What do you suspect might be the problem? He says when he gets the screw out that he is not going to torque anywhere near spec.
I think there is some misalignment somewhere.
I agree –some misalignment somewhere. SO what happened now?
I live close to Pittsburgh and Cleveland. Can you refer me to a dentist to remove a broken abutment screw?
I am sorry-I do not have a direct referral.
I have full denture implants (8 screws). If an implant screw is NOT broken, does it ever need to be replaced as a maintenance process? thank you.
No. If the implant itself is fine then you are ok 👌
The last two (yes two) dental implants I’ve had, have had the abutment screw turn loose of the implant. Both were crowned. One came loose and the dentist could not (or did not know how)remove it. The other simply came out altogether crown attached. This is after only (3 weeks for #1) and 2 days for #2. What gives? (pun intended) Could she be using defective abutments? And if so what should I look for?
hmm….this is very odd. Very difficult for me to answer without actually seeing you and an x-ray but something is wrong here. You may want to have a second opinion so that you don’t end up breaking the implant platform. I can count on one hand in the last 20 years of doing this how many times I have had a screw come loose.
sorry for your troubles… This is not normal
My dental implant screw came out for 2 days before I could have it replaced. It was quite painful, but my surgeon said the implant was solid as a rock. Within a few hours I had more pain and swelling. The next day even more pain and swelling- couldn’t close my lips all the way… the pain is throbbing and severe, even after taking motrin around the clock and ice compresses. They didn’t clean my mouth or the implant hole out before they replaced the screw… I even asked about it and was told it wasn’t necessary. It’s the weekend of course, so the on call dentist put me on amoxicillin which I have been on for 24hrs now with not any real change in the pain or swelling. Will this get better soon, or may I need IV antibiotics? Please help, I am in so much pain and so miserable! 🙁
Strange. Should get better in another 24 hours.
Dr. Amin,
What does it cost to tighten a screw on a screw retained crown dental implant?
There is usually a bigger problem when a screw is becoming loose. There are a plethora of issues that may be happening like the stripped screw, a stripped internal hex on the implant itself, poor material on the implant, a heavy bite, a cast Gold abutment, or a over contoured restoration.
Screw loosening is very uncommon and if it remains loose for a long time you may end up losing everything altogether. We need to see somebody very quickly. Cost can be variable because sometimes something that seems extremely simple ends up being highly complex.
I hope everything works out for you.

Thank you for your response. I am planning to call you Tuesday (tomorrow) to discuss. After that I will fly down to your office for extraction of this broken screw.
when you speak to my staff, email them an x-ray so I can see it first.
😉

I have broken strausman’s implant screw. It was broken while my dentist was delivering crown about 2 months ago in Hawaii. I have moved to North CA and went to implant specialist for broken screw removal. The specialist Doctor could not remove the broken screw yesterday. He said too much torque was used which broke off the screw. He tried reverse drill no luck said screw is too tight. Reverse drilling was dental tech’s idea, not the doctor’s and I am not sure if reverse drill method was done properly. Now I am scheduled next Friday to remove the implant surgically, bone graft and 5 months later start all over with new implant with a price tag of over $4100.
I am not sure what to do need information in making this decision. I am not sure if this is the proper route. Any ideas Dr. Amin? I would appreciate any help.
Hi Mohammed,
Wow, that is not a typical story. Broken screws are not impossible to remove but they are difficult. I would assume that the head broke off and only the threaded portion is there. It should be able to be removed. It is very rare to break a screw on the insertion. I have never done that. Screw removal requires a lot of patience.
I would try at least 1 more time with another dentist before removing the implant. Let me know if you end up in Burbank! It may cost less than a new implant!

How much does it cost to fix broken abuntment screw ?
Hello koriko,
Fixing a broken dental implant abutment screw is highly variable in cost.
This is due to the fact that a single abutment screw may take 1 minute to remove or it may take 2 hours to remove. Also removing the broken abutment screw may require sacrificing your existing dental implant crown and abutment. This would require you to remake a brand-new abutment and crown. The angulation that the dental implant was originally placed in is going to be a big determining factor on the ability to retrieve and replace a broken abutment screw.

I had denist specialist in Columbus ohio he tried reveris drill he tried a pick to unscrew the pin denist said he could turn the pin about a haft turn I think he mest uwhat do youp the threades and could not get it out and charged me 450 dollars for nothing what do you think
Hi Raymond,
Ugh..broken screws are no fun. Have him try to re-thread the implant for a new screw once you get it out. Screw removal is not for the inexperienced dentist. Maybe find someone else.
Sorry!

I have an lower complete over denture on 4 implants. One morning I noticed my denture was loose. I tried scheduling an emergency visit that day, however I was unsuccessful. By the end of the day the denture came out. All 4 screws broke off in the implants . Help
Yikes! I am guessing the it looks like this with multi-unit abutments? Hopefully some new screws will get this fixed!

Hello Doc,
Interesting article. Just had my first ( hopefully only) fractured abutment screw in 15 years. Been wondering how to get it out. Surgery was done only 2 years ago. Many thanks for the blog. I’ll come back to let you know if I have any joy. Wish me luck .
Hi Wale,
Yes, please keep me posted. It is not easy to remove broken dental implant abutment screws!
