Long-term survival of teeth in the posterior region after apical surgery.

Oftentimes the discussion of long-term success rates and treatment modalities becomes a central issue in consultations with patients. The aim of this study was to retrospectively evaluate survival rates of teeth after apicoectomy in an established private practice for Oral and Maxillofacial Surgery in Kiel, Germany. All teeth treated with apicoectomy between 2001 and 2006 were included.

Reconstruction of the orbital floor with polydioxanone: a long-term clinical survey of up to 12 years.

Fractures of the orbital floor are common in injured patients, who often require operation to prevent complications and, among other materials, polydioxanone is widely used. The aim of this study was to evaluate the long-term outcomes of fractures of the orbital floor that had been reconstructed with polydioxanone foil. A total of 101 patients (73 men and 28 women) who had reconstruction of the orbital floor for defects of 2cm(2) or smaller with polydioxanone implants, over a mean (SD) time period of 8 (2) years were evaluated.

3D-tracking the regenerative potential of the mandible with micro-CTs.

Purpose: The treatment of large bone defects is a challenging problem especially when the mandible is affected. Bone healing is dependent on the defect size and the integrity of periosteum. So far, these both aspects have not been investigated separately.

Endocultivation: metabolism during heterotopic osteoinduction in vivo--monitoring with fiber optic detection devices.

Reconstructions of facial bone defects are one of the most challenging aspects in surgical treatment of malignant diseases, large facial traumata, or congenital anomalies. High-level reconstruction techniques are often associated with an elevated morbidity by the harvest of autologous bone grafts from the patient. Tissue engineering techniques may help to solve this problem.
