Allograft with Calcium Sulfate Mixed In: Best Technique?

Dr. K asks:
I am currently placing allograft material in my extraction sites (demineralized cortical bone or mineralized cortical bone) with Calcium Sulfate mixed in. I am getting very good results. Has anyone else had this type of success? Are there any other potential methods that are better than this technique?

  Yes,I have use calcium sulphate in combination with xenograft(mineralized bone graft),not mixed but as a resorbable membrane covering the graft about 3 millimeters of the upper part of the alveolus.In this case not needed resorbable or not resorbeble membrane.
  I have use this technique in 15 cases with big sucess.
  In your case, the mixing of the calcium sulphate with allografts,prevents the dispersion of the graft’s particles.

  I use this method all of the time…using demin cortical and dentogen CaSO4….the calcium sulfate acts almost like a mortar…it keeps the graft in place to heal…I have grown 3mm ridges into 13 mm using the simple onlay procedure with GREAT success…you are on the right track…keep doing what you are doing…you also might want to think about using pericardium as a membrane….I have had MUCH better results with this product than with resorbable collagen membranes…the pericardium has connective tissue which is a huge PLUS! It is expensive though…unless you go to the right place…found Regenetix as a wonderful source for all products….works with a TOP NOTCH tissue bank….quality tissue which you won’t have any recalls like I had with Zimmer in the past…

  Mineralized content has a higher calcium content which will slow your healing process, however it is still good stuff…again just make sure your bone is from a tissue bank which is AATB certified!

  As we all know CaSo4 is Plaster of Paris. It works as an additive to extend other grafts but it is not as great when used alone. Its flow is measured by its powder to water mix. I use Cerasorb with blood or PRP. PRP is a great extender and contains bone growth factors. CaSo4 is inexpensive and can be used to extend the use of an expensive graft material. Somethimes it is good to know the essence of a material and not just its chemical name.

  Yes, I use this all the time and it works great!! The osteoclast at the surgical site creates an acid and this acid condition may inactivate the BMP’S. Therefore, I feel the pH of the site is increased by the addition of CaS04 to assist the osteoblast in the formation of bone. The ratio is; one part CaS04 and 4 parts demen bone. It really works.

  We have used only a Ca Sulphate and Beta Tri-Ca Phosphate product (B-Tcp in a hydroxyl sulphate matrix) for the last 5 years in all my cases(defects and Sinus)with great results which we shown in lectures both here in the UK and in Europe.Our orthopedic and spinal collegues have expressed thoughts that the Ca sulphate is a vital component.
  The future is non use of traditional membranes in grafting as it prevents periostal blood supply (85% of the blood)to the graft site.
  These materials can be used to seal lateral windows and cover defect sites over the graft material.
  We never add autogenous ,to prevent osteoclastic activity , avoid the donor site morbibity and finally when lecturing on the concept if you show a big defect repair and add autogenous some may say it was the autogenous not the graft amterial.

  In response to the above stated. I currently use all Zimmer regenerative products. They have always give me and the patients excellant results. The Tutoplast process is by far the most comprehensive sterilazation process on the market. I have never experienced a recall of procducts as stated above.

• NJHamp February 6th, 2009

  
  

  Correction…to the above statement!!!

  ZIMMER has had recalls in the past…

  http://www.cdsbc.org/pdf/Tissue_Recall_Oct_2005.pdf

  Don’t speak of something you know nothing about!!! Tutoplast process is not the most comprehensive…old technology…3 of the top 5 tissue banks in the country use the patented LifeNet Allowash procedure…these 3 are all non-profit organizations…I say this because it is in the non-profit organizations minds to pick the best cleansing procedure on the market.

  You must sell for Zimmer…who by the way gets most of their grafts from RTI (who is a for profit tissue bank and almost went bust a few years back because of recalls and their recovery process)

  DRs…do your research when you see things like this posted!!!

  Hi, NJHamp,

  Good post.

  I am going to do block bone grafting, I heard some materials, such as Purous(Zimmer), Lifenet. Would you please recommend campony(s) which provide block bone(allograft)? Thanks.

  To Larry Luo, You may want to consider Rocky Mountain Tissue Bank for your bone products.

• NJHamp March 3rd, 2009

  
  

  First off…Rocky Mountain is very limited in their grafts….currently a 6-8 weeks wait! They are very small time and don’t have a true significant edge on current allografts being distributed via other bone banks. They harvest from the vertebrae, which thy claim is the best…yes and no…again there is no study to show a TRUE significant statistical difference than using freeze-dried

  Now to answer your question Larry Luo…Regenetix is a great place to start…I get all my grafting material from them. They work directly with CTS - 5th largest bone bank in the country. The prices are the same as if you ordered directly. I order from them because of the customer service quality…very knowlegable about other techniques used in dentistry. If you call the tissue bank then you will get someone who is paid mainly to take orders…and since I dot pay any more going through them then it is a no brainer.

  LifeNet is a good tissue bank as well…but CTS processes the same way and costs less…

  I have heard CTS a currently looking into producing a graft similar to the JBlock…for right now ask for a bicortical or tricortical bone block and shape to your specifications. Email Regenetix…they will call u back promptly and they can help you on ordering what you need.

  Good day!

  yes, I agree with NJHAMP.LifeNet health Allografts are good products. They really process their tissues well and handle their donors with care too. They have scientific studies to prove that they are indeed a leading tissue bank in processing and sterilizing allografts. That is the first base to begin with in choosing allografts from tissue banks. You can never go wrong with LifeNet Health. Their customer service is superb. Plus, they have a wide range of products for your usage. Try using their perio-fascia lata on your sinus lifts. They are good and really affordable.

  They also have studies to prove that their technology (allowash xg and the PAD) improves their allografts to an optimal range of osteoinductivity and osteoconductivity.

• NJHamp May 25th, 2009

  
  

  As I stated before, Community Tissue Services has licensed LifeNet’s patented Allowash XG technology as well…they are also about 30% less in cost than Lifenet…

  They also have a very conservative selection criteria for all their donors. They definitely take the necessary steps to ensure the safety and efficacy of their product.

  Good day!

  do u know any brands for calcium sulfate in europe??

• Kalberk May 30th, 2009

  
  

  I have just started to use calcium sulfate for socket grafting but I can’t get it to set even with the accelerator liquid. It seems that blood affects it. What am I doing wrong? I am afraid that some of the calcium sulfate will be washed off from the socket.

• NJHamp June 23rd, 2009

  
  

  The directions for the Calcium Sulfate say to only use the accelerator liquid on the top when you are through packing. Use the Saline to moisten the powder….don’t get it too runny…then pack in layers…don’t pack too much at a time as you will loose vascularity.

  It is better to use an allograft mixed with the calcium sulfate. The particle size is perfect for receiving good blood supply and the calcium sulfate acts as a scaffold for the allograft and to assist in clotting the blood to start the healing process.

  Try 1/2 CaSO4 & 1/2 Cortical Bone (Demin or Mineralized…Demin will heal quicker due to lack of calcium content in the bone)

  I RECENTLY ATTENDED AN IMPLANT COURSE WHERE A DENTIST WHO WAS GIVING A COURSE, RECOMENDED USING A BONE GRAFTING PRODUCT CALLED REGENFORM.FOR ALMOST ANY TYPE OF AUGMENTATION, HE IS USING THIS PRODUCT ISTEAD OF LARGE INLAY AUTOGENOUS GRAFTS, THIS SOUNDED VERY EXITING BECAUSE,ONE CAN AVOID ADDITIONAL DONOR SITE SURGERY,DOES ANYONE ELSE USING THIS PRODUCT , WITH SAME SUCCESS?
