β-Tcp for defect reconstruction in oral and maxillofacial surgery—results of more than 500 cases

A criteria for application of ceramic bone substitution material is the demand of a programmed bone ceramic substitution with the possibility of a biological remodulation of the bone ceramic material. The aim was, to examine retrospectively which advantages and disadvantages of β-TCP could be found.

In the time period between 2006 and 2010 in 540 patients β-TCP (Cerasorb ® , Riemser) was used in cases of removal of odontogenic cysts or augmentation of the jaw with implant insertion. In cases of cysts defect filling β-TCP without autologous bone was used, in jaw augmentation a mixture of TCP and autologous bone. All patients got an antibiosis prophylaxis, postoperatively. 6 month postoperatively clinical and X-ray control were performed.

Altogether in 450 patients (mean age 47 years) a defect filling after cyst or tumor removal and in 90 patients (mean age 50.5 years) a jaw augmentation were carried out. In both groups after 6 months a good bone healing could be found. In 20% of the patients with additional resection of the root of the teeth and cystectomya new apical granuloma could be proved. Especially, in augmented patients despite the mixture with autologous bone and membrane technique a different partial resorption could be seen.

During the first 20 weeks a progressive loss of the implanted ceramic was seen (70%) caused by a progressive hydrolytic and cellular process. After that time the rest ceramic which is integrated in the bone trabecula is physiologically remodelled. Clinically, this βTCP-ceramic can be recommended for bone defect regeneration.
