Man, this is such a cool application of physics to dental implants. I almost feel qualified to critique different implant designs now (and I'm not even a dentist)!
Ok that’s nice but I have 2 questions 1 the screw and bolt aren’t tapered like most dental implants so is there a difference here? 2 does this apply also to immediate loading too ?
1. You're absolutely right that the screw and bolt are parallel-walled, but for the purposes of thread load distribution, the principle works exactly the same. 2. The Five Thread Rule was designed for predicting dental implant stability in fresh extraction sockets, but it can also be applied to sub antral cases as well. Thanks for the fantastic questions!
Awesome! If the doctor gets all 21 guidelines correct, the implant material doesn't carry as large of a potential risk. However, the real problems arise with a replica implant when you don't control for all of the other risk factors, as most fatigue failures are time and force-dependent. Many complications from lower-quality materials and implant designs arise only years after restoration!
In engineering, the standard for minimum thread engagement of a bolt is for the bolt to fail in tension before the thread interface fails in shear. You have to account for the ratio of strength of the two materials (implant and bone in this case), bolt diameter, and thread pitch. 5 threads is not some standard. For steel in steel threaded connections there's a common general rule of thumb of 1-1.5x bolt diameter for engagement.
This is true. So for a 5mm diameter implant with a thread pitch of 1 thread/1mm of implant length the answer is 5 threads;-) I though it best not to complex the guideline with where it comes from and focus on the premise of predicting primary stability in fresh extraction sites. When we teach the Five Thread Guideline we cover bone quality, quantity, implant diameter, implant pitch etc to ensure the doctor has the best chance to provide the patient with ideal low risk solutions. If you are a dentist I am impressed:-)
Very very educational . ❤ please advise if u only use autogenous bone graft and if substituted , which type is used and it’s advantages and disadvantages 🙏
I primarily use autogeonous graft, but also use a cortical/cancellous mix and occasionally xenograft in my practice. We'll add advantages and disadvantages to our filming list!
If they're planned and placed correctly, and if you use the right implants (and the patient isn't a smoker), they should last the rest of the patient's life without complications!
Everything is clear, thanks, doc, very userful for beginners
Glad it was helpful!
8:21 buccal and lingual 🤓
all day long!
😂😂😂❤❤❤
I use this every day. I hope it helps you too.
Oh man, very very educational content doc, concise and straight to the point info, much appreciated!
I’m glad you like it

thanks for the kind words my friend.

I get very consistent results with Implant Directs Legacy line as well.

We're very happy to use this at our practice 🙏

THE BOSS OF implantology 🎉❤
Thank you my friend
you are the best! love the way u present it in a fun way
We like to have fun! Thanks for watching!
We're big fans of your background colors 👀
thank you
How long do dental implant last
If they're planned and placed correctly, and if you use the right implants (and the patient isn't a smoker), they should last the rest of the patient's life without complications!
Cool vid thanks doc!
My pleasure
FIVE THREAD'S RULE !!
Thanks for watching
Great. Thanks well explained
Glad it was helpful!
Excellent explanation dr i really appreciate ur knowledge and clinical experience
I'm so thrilled to have the opportunity to provide you with amazing content, and I really hope you stick around for more exciting updates!
