Sixty-two ceramic implants (Frialit) were installed in 53 patients with agenesia or loss of single teeth due to traumata or infection. Sixty-three per cent of the implants were operated in immediately after tooth extraction, whereas the rest were installed in a healed bony alveolar ridge. Eighty-five per cent of the implants were replacements for maxillary incisors. The average observation period was 4 years. During this period 10 implants were removed due to lack of osseointegration. Seven of these implants were lost in the healing period, the remaining 3 were removed after installation of the suprastructure. Eighty-four percent of the implants were successful after 4 years. Trauma in the maxillary region have caused fracture of the implants in 5 patients. Such incidents create therapeutic problems difficult to solve satisfactorily.
62颗陶瓷种植体（Frialit）被植入53例因外伤或感染导致单颗牙齿先天性缺失或缺失的患者体内。63%的种植体在拔牙后立即进行手术，其余的则植入愈合的牙槽嵴中。85%的种植体用于替换上颌切牙。平均观察期为4年。在此期间，有10颗种植体因骨结合不足而被取出。其中7颗种植体在愈合期丢失，其余3颗在安装上部结构后被取出。4年后，84%的种植体成功。上颌区域的外伤导致5例患者的种植体发生骨折。此类事件产生了难以令人满意解决的治疗问题。
