PRF for socket preservation?

Buenas tardes, con mi equipo hemos estado utilizando LPRF para preservación de alveolos como material único, solo en casos en los que estén conservadas las paredes del alveolo, obteniendo muy buenos resultados en cuanto a la regeneración ósea.. En casos donde falta alguna de las paredes del alveolo (generalmente la vestibular), es recomendable utilizarlo en conjunto con algún injerto particulado. Espero le sirva lainformación Saludos cordiales

I recently started to do that. It has been only 3 weeks since I got my unit and I performed 3 procedures so far. I will be opening flaps for all of them just to see if there is any difference. I saw few slides before and after at AAID CE(managing bone deficiencies) in St.Pete and the result was promising.

hi it's necessary to use the "rocks" for socket preservation ... and up the prf if you like sincerely Gianluigi Giammaria Pescara, Italy

Prf has no significant effect on bone regeneration, despite all the claims by its inventor. Just read the current literature. I believe in a few years time when sufficient data is published we will see an end to this prf hype in the same way as its predecssor prp. Why are we interfering with a normal healing process?

If you want volume preservation you should place a non or slowly resorbable particulate graft. If you want the best quality and fast bone filling and you are not worried about loosing some tenth of millimeters width, you shouldn't place anything or place platelet rich concentrate (don't care how you name it). An optional approach would be to place an immediate implant with an immediate provisional restoration with tissue support for Alveolar soft "Would you tell me, please, which way I ought to go from here?" "That depends a good deal on where you want to get to." "I don't much care where –" "Then it doesn't matter which way you go. Lewis carol

I have been using a-PRF for a year now . In the last 6 months or so I would place it in Every extraction socket . Doing an average of 5 per week . I've used it also as in aid in horizontal bone augmentation. Fantastic results so far. No dry sockets , decrease healing time , and definitely preserving the width and height of sockets. I can Highly recommend it .

I would like to venture into the PRF arena since I am doing IV sedation anyways. Does anyone have a recommended system to purchase?

Any self containing defect with good clot stabilization will preserve ridge. Prf is good in clot stability.

I've been using PRF for over 5 years. We place it in 95% of sockets. It is remarkable in many ways much like the comments above. I would say that if you want to preserve the bone don't reply on PRF alone. You will have to go back and do a ridge augmentation. Place a corticocancellous graft and cover it with PRF, don't flap if you can, secure the PRF with a vicryl suture if needed.

You can place anything in a socket or even leave it empty. You will get bone but the question is the long term dimensional stability. I'm yet to see any literature on this regarding PRF in sockets.

The greatest advantage to PRF is the healing time. We place it for all wisdom teeth exts. Honestly, we've only had 2 or 3 cases of dry socket in the last 5 years. I don't always place corticocancellous bone with the PRF. I only use the corticocancellous bone for "dimensional stability", or when I know that I want the bone to be there when I come back.

I would like more info on PRF, I use PRGF and they have raised the prices on the kits. That's why I stopped using PRP. Please advise.

If anyone wants a literature review on the various platelet rich preparations our scientific staff has put on together a current literature review on the subject. Give our office a call and we will be glad to email it to you. Greg Steiner Steiner Biotechnology

We have been using PRGF for many years now and routinely put it into extraction sites. However, I would challenge anyone to look at a healed extraction site or a healed implant surgery site and say "wow, they definitely did/ didn't use PRGF/ PRF etc..." So why do we use it... I don't know if it the placebo effect or the PRGF, but patients have noticeably fewer complications and post op discomfort when we use it. With extractions you have noticeably less bleeding (less post op phone calls etc...) Not sure about less swelling... we still get plenty of that and also we are using dex etc... when the pt is worried about swelling. It is amazing with autogenous and xenografts from a handling point of view especially in sinus grafts/ GBR/ socket preservation techniques. It is an adjunct to what we do at WHRDP, not a replacement, i.e. we whet the implant surface with PRGF before placement and put factor 1 (growth factors and fibrin) directly into the osteotomy. Where we would normally use a collagen membrane we still will, we just then cover this membrane with a fibrin rich membrane made from the PRGF, which really seems to help with the post op healing as previously discussed. I know the evidence is patchy and mostly from the inventors (like so often, it is….) but like one of the posters above I think biotechnology is the future. It just makes sense to me. Some of the biggest critics are people who soak their grafting materials in whole blood. This is just taking it one-step further and I think that I would rather have a concentration of growth factors and fibrin than whole blood even though I accept there may be less oxygen available for healing without RBCs. If we have problems when we have used PRGF (and you still do regardless of what the inventors say… they are just less frequent) – We can reassure the patient that we did everything we possibly could to get a satisfactory result. Which helps some of them, which in turn helps us. Paradoxically (and this is not a reason for using it) – When people decline to have PRGF and then go on to have problems, it is amazing how often they comment that they should have had it/ or wished that they had had it… rather than blaming me… so happy days.

Nelson Pinto has been doing some great work with L-PRF. He spoke in a breakout group at the recent ADIS summit in Atlanta. Things have progressed much further with the socket preservation techniques. He had slides that resembled Marks with BMP on regeneration. It is technique sensitive. L-PRF will grow what it touches . In ext sites he removes the cribiform plate with a round brand then punctures the site. Places 6-8 membranes and fully condenses them to extraction site as much of the liquid as possible. .If buccal plate missing he will place a layer exterior to the plate over the buccal plate 5mm each side of the defect . The last 2 he places at opening tucking under the margins and expects to loose the top layer. If you dont remove the cribiform plate you get bone that is too dense. If you remove it then you get medullary bone
