background: the aim of this study was to determine the pattern and amount of change exhibited in mandibular intercanine and intermolar width during treatment and assessing its stability1-3 years post-retention. materials and methods: the material consisted of 70 cases of which 20 cases were treated without extraction and 30 cases were treated with extraction, which were compared with 20 untreat...
The development of new functional materials is crucial for addressing global challenges such as clean energy or the discovery drugs and antibiotics. Functional material systems are typically composed molecular building blocks, organized across multiple length scales in a hierarchical order. large design space allows precise tuning properties to specific applications, but also makes it time-cons...
BACKGROUND Bone preservation is an essential issue in the context of last teeth extraction and complete edentulism. The intended treatment, whether a complete denture or an implant placement, is facilitated with a voluminous residual ridge. Bone resorption after multiple extractions has not been as well studied as the bone resorption that occurs after the extraction of a single tooth. Recent ad...
