Q&A

What are the ingredients in R.T.R.®?

R.T.R.® is a resorbable synthetic bone grafting material containing ß-TCP (ß tricalcium phosphate). R.T.R.® cone also contains collagen of bovin origin.

What about the resorption of R.T.R.® ?

R.T.R.® is resorbed very slowly in 3 to 6 months. Studies show that the amount of R.T.R.® in the augmentation material declines steadily. We used to believe that a bone substitute had to be resorbed as quickly a possible. But these days, it is known that the slow breakdown of RTR gives the bone augmentation material volume stability.

What is the role of the collagen in the R.T.R.® cone?

The collagen allows the cohesion between the granules as to maintain the shape of the cone as well as maintaining the granules in place when suture is impossible. Besides, the collagen helps the formation of the clot and the fixation of the growth factors that are realased by the system. Thereby, the collagen promotes the healing.

Is it safe to use the collagen of bovine origine contained in R.T.R.® cone?

The collagen comes from 6-month-young bovines, bred in the USA. Its purification and sterilization comply to the european security regulations.

Can R.T.R.® be re-sterilized? R.T.R.® is already sterilized. It should not be re-sterilized as it is not approved for re-sterilization in dental practice. Septodont, as the manufacturer, cannot accept product liability in this case.

For which grafting indications can I use R.T.R.®?

R.T.R.® can be used for post extraction socket grafting, ridge augmentation, periodontal defects, peri-implant defects, large defects (e.g. following apical endodontic surgery), sinus lift.

Why is R.T.R.® better than other synthetic grafting materials?

R.T.R.® (syringe & granules) is pure-phase β-TCP and does not contain other components. Thus, its resorption occurs completely, allowing a new bone growth. Also, as R.T.R.® is available in 3 different presentations, it can be used in many different bone grafting procedures.

Why is R.T.R.® preferable to biologically-derived grafting products?

With R.T.R.®, there is: 1) No risk of transmission of disease such as Creutzfeldt-Jacob 2) No problem of supply.

How to use R.T.R.® ? - Cone :

R.T.R.® cone is inserted in the dental socket after waiting that the socket has been filled with Blood.

- Syringe :

All the granules must be soaked with some blood or physiological solution absorbed through the filter tip of the syringe. The excess liquid is released, the tip removed and the mixture injected into the surgical site.

- Granules :

R.T.R.® Granules is mixed in a sterile Dappen dish with the patient’s blood or physiological solution before being placed onto the clinical site using a dental spatula.

Should I use R.T.R.® in all extractions or only for sockets where implants will be placed?

R.T.R.® should also be placed whenever alveolar ridge preservation is needed (eg, aesthetic reason for a bridge).

Is it mandatory to close the surgical site with sutures?

It is always better to suture the operative site. However, should suturing be impossible, R.T.R.® cone is particularly recommended.

Can R.T.R.® also be used without membrane?

A membrane is usually used as a barrier against the growth of soft tissue in the event of postoperative wound dehiscence. Otherwise, as long as it is possible to close the operatory site and as lons as the granules stay in place, it is not mandatory to use a membrane with R.T.R.®.

Should R.T.R.® be mixed with antibiotics?

The use of antibiotics is generally unnecessary when employing R.T.R.®. If antibiotic therapy is indicated, it should usually be given systemically.

Is it better to use autologous bone than R.T.R.® for sinus lift procedures ? A prospective multicentre randomized clinical trial* comparing autogenous bone and ßTCP in the case of sinus lifting showed no significant histologic or histomorphometric difference between the two techniques. * Szabo G et al,Int J Oral Maxillofac Implants 2005;20:371-371

Formation of new bone of acceptable quality and quantity permitted the placement of an osseointegrated dental implant. Further study of this material and this protocol is needed and a case series is currently underway. 2006

Jensen O, Use of alloplasts sinus floor grafting in: the sinus bone graft. Chicago: Quintessence 2006:201+209 (Second Ed) Pure-phase β-TCP offers ready availability in unlimited supply of a material that is free of allergens and foreign proteins and avoids second-site surgery for bone harvest. The material is resorbable, easy to handle, predictable, and compatible with the barrier membrane. It also reduces surgical treatment time.

Princ, G, Bert M, Ifi JC, Utilisation du substitut osseux ß-TCP, résultats à trois ans. Le Chirurgien-Dentiste de France n°1250/1251, 23-30 March 2006 After encouraging short-term results, the ß-TCP as bone grafting material shows a good stability in the results. Bone grafting in the porosities of the material proves that a colonisation by bone cells is possible, developing with time. Ormianer Z, Palti A, Shifman A, Survival of immediately loaded dental implants in deficient alveolar bone sites augmented with beta-tricalcium phosphate. Implant Dent. 2006 Dec;15(4):395-403. This study assessed the survival of immediately loaded dental implants placed in deficient alveolar bone sites at bone grafting. In all cases, beta-tricalcium phosphate was mixed with blood from the surgical site to augment the ridge level or fill spaces between the implant and socket wall. When indicated, the same materials were used for sinus floor augmentation. Within the limitations of this study, immediate loading of splinted implants in augmented sites is a predictable procedure.

Cariou F, RTR, Protocole clinique du comblement alvéolaire avec de l’os synthétique alloplastique, Clinic, nov 2006, vol 27,519-524 Reliability of ß-TCP as bone grafting material and its resorbability have been proved in the studies. Thanks to a combination with collagen, RTR cone allows an easy use of ß-TCP in a daily practice. RTR is recommended every time an implant is considered, especially in areas with bone defect or in ridge preservation for aesthetic purposes (bridges).
