Abstract

The amount of available alveolar ridge is an important factor in planning to replace a tooth with an implant. Inadequate bone height and width may compromise the implant placement. Therefore, augmenting ridge defects is essential in the proper installation of the implant. In case an implant is placed in a defective ridge, additional augmentation will be required in order to improve the aesthetic appearance. An osteoconductive bone substitute promotes bone growth in periodontal and maxillofacial osseous defects. It provides the body with a matrix for bone cell migration and is integrated into the natural physiologic remodelling process. In order to investigate the osteoconductive bone substitute, particle analysis was used. Numerical simulation and optical coherence tomography were employed in order to analyze the results of the remodelling process. A particle analyzer can offer two complementary measurement techniques. Its concept integrates laser and video measurements to provide complete sample information on both particle size distribution and particle shape distribution. The analyzer used can measure particle sizes in a range of 100 Nanometer up to 3600 Micron. Numerical simulation provides information concerning the biomechanical behaviour of the augmentation materials in the whole bone volume. For the Optical Coherence Tomography Investigation, a combined OCT/confocal system operating at 1300 nm/970 nm was used. This has a high numerical aperture (NA) interface optics which gives a small field of view of 1 mm by 1 mm with a transverse resolution of better than 4 mu m. Results of bone remodelling process are presented using different osteoconductive bone substitutes which have been proven through years of clinical experience.
