Sir what is the long term longevity of Alveolar bone created by particulate grafting methods?

I totally agree with your concept. It seems to me when adjacent teeth / PDL are present (mesial and distal) BMP shouldn't be necessary. In addition, grafting materials with faster turnover rate will be more predictable overtime with out BMP2 use.
On the hand, if no teeth /PDL are present grafting materials with slower turnover rate may benefit from BMP2 use.

Clinically I don't care about the size of pore. I have used many commercial Ti mesh for ridge augmentation from micropore (Cytoflex) and macropore type All looks okay.regards. DS | | Register For Free To Reply |

do u prefer to use meshes with micro pores or the larger ones?

| 2012/8/23 21:38:31 | Dong Sohn | | 3D ridge augmentation | | Dear Dr. Martin,
Thank you very much for your comments. I believe that BMP 2 contributes new bone foramtion in the defect as you mentioned.
What I mean is that we can have same result without BMP-2. I been lost of augmenation w/o BMP for many years and results were good if mesh was not exposed early. Sincerely..DS | | Register For Free To Reply |

excellent conversation and post- If I may reply to your question about rhBMP2- I have utilized since 2006-07 and have been suprised at times by the volume of bone and type of defects that I have been able to manage with the right type of carrier- be it mesh or CurV- I believe it is well worth the cost in the given situation- If you search my name in the XP files you can view some of my results. | | Register For Free To Reply |
| 2012/8/21 21:33:39 | Dong Sohn | | 3D ridge augmentation | | Dear Dr. Salama, Thank you so much fror your kind comments.
I never used BMP-2 before because this is not allowed in my country. However according to some articles which I read, It seems that no big diffreences of healing time between between BMP used augmentation and Non- BMP used augmentation.
What do you think about that ?
Do you think that BMP2 has more advnatages over the surgical cost to purchase BMP 2?
Anyway I hope to meet Infuse and to have chance to use in my country sooner or later.
Thank you

| 2012/8/21 8:52:12 | Maurice Salama | | 3D ridge augmentation | | Dr. Sohn. Thank you for your kind reply. Your reply is excellent as a source of information that can be utilized as a basis for any successful regenerative procedure.
My only concern, as you also suggested, would be to "delay" implant placement until after regeneration.
I am curious if you have any experience with BMP-2 under Mesh for these type defects as this is getting much attention.
Always nice to interact with you.

| 2012/12/19 21:42:32 | Dong Sohn | | 3D ridge augmentation | | Yes Dr. I sometimes do soft tissue surgery to make attached keratinized gingiva around implat . Than you DS | | Register For Free To Reply |
| 2012/9/25 17:31:45 | Stefano Petti | | 3D ridge augmentation | | Excellent work Dr. Sohn, but wath about mucosal tissue overlapping alveolar ridge afther healing ? It needs an apical transposition afther implants exposure ?

| 2012/8/20 21:35:29 | Dong Sohn | | 3D ridge augmentation | | Yes, Dr. Salama, I'd like to recommend this tech. for 3 D ridge augmentation.
The key for successful ridge augmentation is tension free suture whatever tech are used for ridge augmentation.
I make releasing incision befor bone graft and make sure that buccal flap should be overlapped 10mm over the palatal flap. After augmentaion procedure, at least 2-3mm overlapping is essential in order to avoid early exposure of mesh.,
Implant placement should be delayed if surgeon is less experienced,
2ndly, gel condition bone using bovine and mineral allograt is highly recommended to stabilize bone graft on the defect.
I loved to use auto block bone for ridge augmentation for last 10 or more years but not any more.
So my first choice of treatment is mesh assited ridge augmentation.
Thank you

| 2012/8/20 17:45:56 | Maurice Salama | | 3D ridge augmentation | | Many thanks Dr.Sohn. Would you suggest this technique to less experienced surgeons? Would you approach these areas in any other way?

Thank you . DS
Take a close at the 3 D deficiency at ant maxilla.
What is your tx. plan for ridge augmentation ?
1) Autologous iliac bone is indicated but too much traumatic to patient and eraly bone resorption of iliac bone can be expected.
2) Chin bone graft. It' too small bone block to cover this large defect.
3) BMP/ alllograft/ Mesh. BMP is too mch expensive and may develeope severe postop swelling.
4)SO My choice is autologous concentrated growth factor / Allograft / Bovine / Mesh.,
Allograft induces fast bone reformation.
Bovine bone prevents bone resorption.
Autologous growth factors accelerates new bone
formation and soft tissue healing.
Mesh is a excellent space maker.
More than 10mm vertical deficiency is seen at ant maxilla,
Implants were placed simultaneously. However implant placement can be delayed.
CGF was prepared before surgert.
The mixture of bone subtitutes/ CGF was placed on the defect.
Overgrafting is necessary.
Mesh was stabilized with mini screw.
To accelerate soft tissue healing, CGF membrane was placed on the mesh.
Tension free suture is strongly required.
6 M healing was allowed. Look at the excellent ridge augmentation.
