Dentin Grafts & Osseodensification
with Dr. Isaac Tawil
"I am fortunate to have been a very early adopter of the Kometabio Smart Dentin grinder, as I was trained by the inventor. This technology allows me to take most extracted teeth and use them as bioactive bone grafts for extraction socket, periodontal regeneration and more. The patients love that their own tooth can be used to enhance the rebuilding of damaged sites in their mouth from missing teeth, areas with gum disease to sinus grafting. Clinically the results are outstanding as the articles my colleagues and I have published on this amazing technology demonstrate. Biologically - the bone is vital as seen under the microscope in our studies. This technology is something to own and use regularly, it's a game changer."
Dr. Abdulsalam Alrmali, Oral & Maxillofacial Surgeon & Oral Implantologist; Staff member at the University of Tripoli, Libya
"Nowadays, dentin autograft that I produce using the Smart Dentin Grinder is an excellent graft material. It is highly predictable and provides amazing bone formation after a few months. I like to use it with growth factors to get sticky dentin graft, easy in manipulation & control for all of my patients to get long term stability around teeth & implants."

"A must-have in your armamentarium for when you are extracting a hopeless tooth and immediately placing the dental implant. The results that I have seen using the patient's own teeth as a graft material have been excellent, exceeding my expectations."
Dr. Marius Leretter
Universitatea de Medicina si Farmacie Victor Babes, Timisoara
“I’ve just managed to save a patient from a sinus lifting by using the extracted molar. Combining with the dentin with the PRF I did not open any package of bone substitute or collagen membrane. Not to mention the bone quality and speed of the implant placement! In the end, I guess I was more happy with the result than the patient himself.”
Ophir Fromovich, DMD
“Following the cases I treat with the Autogenic Graft made by the Smart Dentin Grinder, I can say it is the easiest way to get the BEST Autogentic Graft!"

“We’ve introduced autogenous tooth bone graft in our clinic to serve our patients’ desire to use their own tissue instead of foreign materials. The dentin graft is handled the same as any other synthetic or allogeneic grafts during surgery, and allows us to make it a high quality and routine procedure in our practice. The results are a game changer - we consistently get vital hard bone very quickly."
“My private practice has been using the KometaBio SDG for about two years. In six-month post-op CBCTs, the autogenous dentin graft is impossible to distinguish from native bone. My success is my patients' success! Which creates more referrals, so more grafting at an insignificant cost.”
Dr. Steve Wallace, DDS, MHS
Adjunct Clinical Instructor, Department of Stomology & Division of Periodontics

“We are seeing terrific results from using autologous dentin grafts for socket preservation, sinus grafting and ridge augmentation! This is a huge leap forward in advancing biologic surgery techniques in periodontics and implant dentistry.”
Snjezana Pohl, MD, DMD
"When the patient with dentin grafted sites returns for implant placement I feel relaxed and confident, knowing that CBCT will show great dimension maintenance, I`ll find a nice amount of keratinized gingiva and after flap elevation a hard tissue that looks like bone and feels like bone."
Ara Nazarian DDS, DICOI
"The Smart Dentin Grinder is an exceptional addition to my armamentarium in providing effective and predictable autologous graft material whether it is a single extraction site or full mouth reconstruction."

"Once in a while, a new product comes along that not only changes your practice it changes your mindset. After using the Dentin grinder for the last few years we are setting a new standard in autogenous graft harvesting by increasing the quality and esthetic outcome of our case and decreasing the risk of infection and rejection."
Gideon Hallel, DMD
“Great idea, so simple yet genius. The Smart Dentin Grinder turns the extracted tooth into an Autogenic particulate graft – an optimal bioactive scaffold for the Socket Preservation. The healing results are excellent! The system is user-friendly and holds its own alongside high finishing standards."

“I think dentin graft has really changed my way to treat patients. Its consistency, biological benefits, friendly protocol and of course the economic benefit, turn this graft into one of my daily practice tools for bone grafting procedures."

“I always prefer to follow the natural biology of my patients. That's why the autogenous dentin graft is so popular in my practice. It's predictable with excellent long term results. Furthermore, it's a great message for my patients. I use it whenever I can for any grafting indication."

“The possibility to use autologous tooth as a graft for bone regeneration has contributed to open a new dimension in bone graft procedures. It is leading to achieve several benefits for our patients in a way that was not possible before, the synergy with other autologous procedures is also raising the safety, predictability and biologic capacity in this new domain."
Dr. Sandeep Singh

“For me the real test of bone graft is upon flap exposure and re-entry. The Partially Demineralized Dentinal Graft I get from the Smart Dentin Grinder provides me with real vascularized bone just 3-4 months after grafting. The bone looks and feels like real lamellar bone. My histomorphological studies confirm the fact every time. Certainly a terrific option I regularly stick to.”
“For 17 years I have tried to go the autologous way starting with bone harvesting then adding BCGF (blood concentrated growth factors). 5 years ago I began using the Smart Dentin Grinder® by KometaBio and felt my treatment philosophy became complete. This was the missing piece of the puzzle. We grew together, and now I can’t understand daily surgery without it. I perfected “Sticky Tooth” made with ground teeth and BCGF and have continuously been greatly satisfied with the results. The Smart Dentin Grinder® is indeed a smart logical choice. Please don’t discard patients’ teeth. It is a priceless source of bone regeneration in your hands, in no time.”

​
With the abundance of augmentation materials available from the blister, what gave you the idea of using the patient's tooth substance?
José Luis Calvo Guirado: I have been working intensively on the structure of the teeth, which is divided into two parts: On the one hand, the root, which has an osteoinductive component because it contains type I collagen and morphogenetic proteins. On the other hand, the crown, which has a very hard hydroxyapatite layer that is absorbed only slowly, and thus serves as a perfect scaffold for the new bone to be formed. In addition, it is the body's own, natural, biological material. So in just over five minutes, we can obtain a large amount of autologous biomaterial that can be used on the same patient, reducing the cost of the augmentation measure.
What scientific evidence do we have besides the positive clinical observations?
José Luis Calvo Guirado: There is a lot of positive scientific evidence that freshly ground tooth substance accelerates bone regeneration, as it improves bone and gum regeneration due to the type I collagen it contains, which we have already mentioned.
The material is extremely biocompatible, as it has the same properties as bone and is perfectly compatible with soft tissue. As a result, we can observe a healing of the gingiva within just seven days.
Always a topic: the safety and non-contamination of an augmentation material. How safe is the Smart Grinder?
José Luis Calvo Guirado: The safety of the Smart Dentin Grinder results solely from the fact that, after crushing with the device, the tooth is divided into two different particle sizes, which can be reinserted into the patient depending on the defect morphology. The disinfection system consisting of a cleanser and a serum as a buffer allows these shredded tooth particles to be completely disinfected before they are reintegrated into the patient's organism.
How does autologous tooth substance compare directly with other bone augmentation materials?
José Luis Calvo Guirado: The main feature of using ground teeth is that the root material can stimulate bone formation and the crown material can maintain the bone structure and stabilize the gums in the long term. It should be emphasized that the autologous tooth substance that we obtain from shredded teeth reduces the amount of biomaterials that we have to keep in stock at all times in our surgical practice. This reduces costs for the practice and the patient.
How time-consuming or, to put it more positively, chairside-friendly is the protocol?
José Luis Calvo Guirado: The application is fast: about two minutes to remove all foreign material and caries from all three tooth structures, six minutes to grind and disinfect the tooth particles, and twice five seconds to prepare with the buffer solution to lower the pH from 11.4 back to neutral 7.1. This shortens the treatment time and improves effectiveness at the same time.
Was there a specific situation in which the method particularly impressed you?
José Luis Calvo Guirado: That was the removal of ten teeth each in the upper and lower jaw, all of which I ground and cleaned in the Smart Grinder. Not only did I immediately reinsert it into the patient, but I also directly inserted 22 implants and the temporary prosthesis. After three months, all implants were fully integrated and the following month the final ceramic prosthesis could be inserted. The height of the maxillary ridge of all implants was not lost during the now six-year observation period, which we attribute directly to this biological tooth material obtained by the patient.
Thank you very much for the interview.
