During the process of manufacturing β-TCP, CERASORB® ceramic particles with an average size of 63 µm are created by sintering and grinding. These are mixed with an aqueous polymer solution in the ratio (by weight) 70 % ceramics and 30 % polymer solution. When using this product, as in all augmentation procedures, it is important to ensure that all soft tis- sue is completely removed so that it is possible for the paste to make direct contact with bone; in the process heavy bleeding should be stopped to make it possible for the material to adhere well to the bone. After history-taking and an initial examination (documented with X-ray images if possible) with explanation of the procedure and consent to the operation, records were made of the treatment and follow-up examinations that had been performed; follow-up examinations were carried out one to two weeks postoperatively, after three, six and twelve months and later if necessary depending on the industry | Fig. 2: Application of CERASORB® Paste in an extraction socket.

When explaining the procedure to the patient it is not necessary to mention the possible complications of bone harvesting, or problems relat- ing to rejection reactions and potential risk of allergic sensitisation and infection, as is the case with biolog- ical materials. Parameters for judging successful bone healing with CERASORB® Paste (“effectiveness parameters”): – bone structure as seen in follow-up X-rays – current clinical status (such as state of mucous membranes, suture dehiscence) – bone situation at implantation – global evaluation of effectiveness/therapeutic success by the dentist carrying out treatment – cases in which treatment was terminated or changed because of lack of effectiveness After the study had been completed, the recording sheets were examined centrally to check complete- ness and subjected to quality control.
