Bone graft materials are more and more frequently used in dentistry for improving the periodontal support and for creating a bone support favorable for the insertion of dental implants. The experimental study carried out on laboratory animals aimed to evaluate the biocompatibility and the manner of integration of an experimental bone augmentation material, based on hydroxyapatite (HAp), reinforced with titanium-based particles by comparison with a commercial synthetic graft material already existing on the profile market, also based on HAp. We noticed a common pattern of evolution, although there were differences related to the speed of new bone tissue formation and implicitly the morphological elements captured at the two moments of time.

This retrospective study aimed to evaluate the frequency of bone augmentation materials used for implant or periodontal surgical treatment depending on the age and sex of the patients from a dental practice in Essen, Germany, but also the implants dimensions and respectively the stage and progression grade of the periodontitis. The analysis of the data showed that bone augmentation materials are used much more frequently in the implant surgical cases (43,33%) compared to periodontal surgical cases (13,33%). While the correlations with sex and age were less obvious, the use of bone augmentation materials in the implant surgical cases was correlated with the use of shorter implants, while their use in the periodontal surgical cases was correlated with the stage 3 periodontitis.

This retrospective study aimed to evaluate the frequency of dental materials use for fixed prosthesis depending on the location of the teeth, the restorative prosthetic type, the age and sex of the patients from a dental practice in Essen, Germany. The analysis of the collected data showed that zirconia is currently the most common material for making dental fixed prostheses, a larger number of prosthetic elements for women and a significant increase for these restorations at ages over 40 years. Most of the prosthetic elements were made in the mandibular molar area, with an increased frequency of zirconia bridges in the mandible, while for the upper jaw the number of crowns was higher.
