Narrow Ridge with Versah drills, GBR and Ritter Implants
Posted on 04.14.2016 11:09 AM
By Maurice Salama
In Bone Grafting
A Patient presents with need for Implant in mandibular right 1st molar. The Ridge is narrow with only 2.8mm of width. 3rd molar also requires extraction. Many options here. We decided to harvest Autogenous Bone from area of extraction with ACM drills and Bone scraper. Ridge Expansion accomplished with OD protocol from Versah and placement of a Ritter Implant 5.0mm X 10mm. Impressively the entire implant was surrounded by bone and the stability was 45 NCm. LAbial Contour grafting still performed with autologus bone, PRGF, Fibrin, Collagen membrane and tacks from Salvin Regen. Dr. Salama

Just Perfect...
It is Site Optimization at its best... enhancing bone plasticity by preservation is the way of the future.
Thank you! for sharing.
Maurice Salama says on 04.14.2016 11:45 AM
In the future...perhaps utilize 3rd molar for bone grafting material?? Tooth Grinder would have allowed for us to avoid harvesting. Thoughts on that as well? Things are changing in our field so rapidly. Got to stay involved with XP Forum. Dr. Salama
Manuel De LA ROSA says on 04.14.2016 09:15 PM
Maurice, beautiful case and extremely well managed. Amazing the results of the densah drills. I like the flap as well with the extension that gives a good flexibility for the complete coverage.
Howard Gluckman says on 04.14.2016 01:13 PM
Agreed Mo. out of interest why a 5mm. why not the narrowest one necessary for that area thereby increasing the amount of natural bone around the implant.
Thanks H
Charles Schwimer says on 04.14.2016 01:37 PM
Mo. Nice case! Much better than bone extraction drilling. Yes things are moving fast on Dentalxp. All aboard! Thank you for sharing. Warm regards. Chuck
Maurice Salama says on 04.14.2016 01:33 PM
Howard; Great question. As I did not expect the amount of expansion I got with the OD Densah burs and was prepared actually to place a 4mm but since I already harvested a lot of autogenous bone chips from the 3rd Molar site and ramus buccal shelf, I decided to go with the 5mm diameter for a large molar replacement and perform the contour graft regardless. I was surprised not to have a dehiscence or fenestration....regards Mo
Steven Berkowitz says on 04.14.2016 01:57 PM
Nice case! When the implant stopped 2mm above the crest at 40N/cm, I assume you hand ratcheted to fully seat the implant? Any concerns about over torqueing and placing too much pressure at the crest?
Maurice Salama says on 04.14.2016 03:21 PM
Steven; Yes, correct. I have a torque ratchet so I can continue to measure my torque. I do not feel that implants have an issue of over torque at insertion as long as it does not damage the internal aspects of the implant. Typically with ritter Implants I am between 40-55NCm which is ideal for immediate and or early loading protocols.
Dr. Salama
Ziv Mazor says on 04.14.2016 03:54 PM
Great case Mo...no doubt this is the way to go . The amazing densah drills changed the way I practice..i hardly use the conventional drills.
Ehab Moussa says on 04.14.2016 08:03 PM
Beautifully managed case Dr Salama !! It is amazing that you did not have any dehiscence, ridge looks NARROW
Would you have still utilized autogenous if you did not have harvest site within same flap?
How long would you wait to uncover ?
Thank you for sharing :)

Hui-Jin Lee says on 04.14.2016 11:05 PM
Great case Dr. Salama,
Its amazing that Versah is able to expand the bone from 2.8mm ridge to over 7mm (5mm diameter implant and possibly 1mm on both B and L) without any fracture or deheiscence. My experience on the posterior mandible usually bone fractures at the last drill. Do you think your patient may had softer site or recently extracted site?
Isaac Tawil says on 04.14.2016 11:28 PM
Hui,
I find this is routine to expand even in the mandible. If you are having fractures in dense bone consider utilizing piezo crestal cut to allow the expansion. They work very well together at high speeds with Densah drills.
Dr S
Great case. I agree using the 3rd molar as graft is another great option. I've been very impressed with the results.
Salah Huwais says on 04.15.2016 11:49 AM
Hui:
Osseodensification is an applied science of Bone Plasticity. We need more trabecular bone and less cortical bone to achieve it.
In other words, the amount of expansion is related to bone plasticity and it is directly related to trabecular bone. Two factors will influence the expansion rate and minimize the fracture risk:
1-The thickness of the cortical plate plays a negative role because cortical bone is stiffer and less dynamic than trabecular bone. Maurice's case has more factors and "finesse" than it shows. The buccal cortical layer in the case appears to be thin so it did allow more plasticity and as a result more expansion with no fracture or dehiscence.
2-The bounsing operation of the burs and the need to introduce small increments of expansion to allow the bone a rate dependant stress to produce a rate dependant strain (ie expansion).
In cases with thick cortical plate and <3mm ridge width, I, personally, create a horizontal groove to enhance elasticity and produce more plasticity.
I hope this helps.

Jorge Campos says on 04.15.2016 07:06 AM
Mo, great case to show a fact: bone plasticity. Versah drills use perfectly well this principle and makes the "miracle" of expanding.
I love the control that assures the use of the drills at 1200 rpm on CCW direction.
Regards.
Jorge
armando ponzi says on 04.15.2016 09:25 AM
Mou, very nice application of Versah concept! I believe we should spend some words about bone plasticity concept: -how does it work biologically? -what structures are modified and how? Thanks for sharing. Armando
Salah Huwais says on 04.15.2016 11:35 AM

My lecture at the JTI in Madrid, next week, will cover Bone Plasticity and osseodensification biomachanics. See you then.

Sergio Correa says on 04.15.2016 10:45 PM
Best regard dear colleagues.
Why not think about of #Piezosurgery procedure? I think it might be less invasive and very good prognosis.
Big hug. Thanks again. Sergio Tobón.
Maurice Salama says on 04.16.2016 04:51 PM
Sergio; Could have used piezo too but this was much easier....IMO regards Dr. S
MARCELO FERRER says on 04.15.2016 10:47 PM
Great case Mo,
Perfect and solid protocol
I believe most people would be terrified to speak about EXPANSION in that area.
You showed a very friendly and non invasive way to look this procedure in a complex area like that for many surgeons. And i think that´s the way it should be, clean, simple, perfect...
I´m using a lot of dentin now and the histological findings are amazing and for sure it will became one more tool in regenerative procedures. Thanks Ziv for sharing that concept also.
Warm regards and Thanks for sharing.
by the way, need those drills
Marcelo
Maurice Salama says on 04.16.2016 04:52 PM
The Ritter Spiral Implant fits perfectly into the sites prepared with Versah...almost seems that these drills were made for this implant system. great combination. Dr. Salama
Masuod Adeli says on 04.16.2016 11:48 PM
Dr Salama, very nice execution. Do you have a pre operative CBCT to share?I just want to see bone density and thickness of the cortical bone.
Maurice Salama says on 05.11.2016 09:42 AM
Masoud; Bone quality was Type 3....
Dr. S
Tim Hacker says on 04.23.2016 10:50 AM
The Versah protocol is very elegant and technique sensitive. I have been using the drills for over a year and I'm amazed every time; ridge expansion, in socket sinus lift...Also, L-PRF will make this case heal quickly and be very stable. Much better and quicker than bone block protocols.
Dr. Salah will be presenting at the Alabama Implant Study Group meeting, August 4-6.
Christopher McFarland says on 05.11.2016 09:22 AM
Do you feel grafting is always beneficial following the Versah expansion?
Maurice Salama says on 05.11.2016 09:48 AM
Chris; Not always but when expansion leaves a THIN labial plate over the threads DEFINITELY BG.
regards Maurice
Thanos Ntounis says on 05.14.2016 04:24 PM
beautiful Dr. Salama... I think I need to get the Versah!
Maurice Salama says on 05.24.2016 10:06 AM
Thanks Thanos...let us know your thoughts? Dr. S
Maurice Salama says on 10.09.2016 09:37 AM
Anyone use the new G2 burs? Thoughts?
richard martin says on 10.09.2016 10:06 AM
Maurice,
I have been using G2 for a couple weeks - IMO- they seem to "hold" the osteotomy a bit more in immed cases - and in thin ridges "grip" the pilot hole especially in dense bone and lastly seem to spread the slurry against the walls of extraction site more uniformly.......
great teaching experiencing this weekend!
Cheers,
Richard

andoni jones says on 02.24.2017 04:01 AM
What a GBR Maurice. With or without the use of the Densah burs, I think that's the real key of this case.
By the way, do you place your fibrin membranes just over the bone, or covering the membrane also?
And have you seen a difference between using the PRGF or not using it?
Thanks
Maurice Salama says on 02.24.2017 11:03 AM
Yes, Andoni the GBR was KEy to the Regeneration but the OD drilling allowed the implant to be placed simultaneously....yes, I love the PRGF and use the Fibrin over the bone graft and over the membrane before closure and mix my bone graft material with the PRGF to create my own version of "sticky bone".
regards Dr. S
Charles Schwimer says on 02.24.2017 11:37 AM
Mo. Another outstanding outcome as always. A perfect example of The SPOT/OD ridge expansion concept. It's all about PRESERVATION of NATURE to optimize the site. You have perform well in typical MAURICE STYLE! Best regards. Chuck
Jorge Campos says on 02.24.2017 11:52 AM
MO, excellent job! This treatment has become a PREDICTABLE treatment option. That´s all we want to have in mind when we have cases like this that are very common.
Thanks for posting.
Jorge
Maurice Salama says on 02.28.2017 05:59 PM
Thanks Chuck and Jorge....yes, I do believe it allowed for a single therapy style treatment...regards Mo
THEO ODYSSEOS says on 12.12.2019 05:04 AM
Mau. very nice protocol, but in the attempt to avoid a buccal dehiscence the implant is place too lingual.
do you have a picture with the prosthetic crown?
wouldn't be better to stage the case, first the GBR and then the implant placement?thanks.
Emad Salloum says on 07.07.2020 03:00 PM
Very nice example for those who may still suspect the efficacy of bone expansion by OD...perfectly done by a master... Thank Mo for sharing Why did you choose a wide 5.0 mm diameter implant ??? why not going little narrower ( 4.2 - 4.5 ) ???
Maurice Salama says on 08.07.2020 04:30 PM
Good question, as a molar site I felt better with a 5.0mm but it had bone surrounding after OD?? regards Mo
Dr. Avijit says on 06.07.2022 01:32 AM
Just right...
It's Site Optimization at its finest... preserving bone flexibility is the way of the future.
Thank you very much! thanks for sharing
Maurice Salama says on 06.07.2022 10:01 AM
Very welcome...6 years ago and still makes sense..
