Filter by:Different classifications to describe alveolar ridge defects have been published over the past years but no single classification has been developed concerning soft tissue volume around teeth or dental implants. Moreover, while several studies investigated the effect of various augmentation techniques and materials on soft tissue volume change and volume stability there is a real gap of knowledge regarding how to evaluate the available soft tissue volume and when to consider it sufficient or deficient which would definitely improve clinical decision making and treatment planing. Therefore, our primary aim was to assess the application of a novel classification system based on the correlation between buccal soft tissue volume and gingival biotypes and, also to assess the sensitivity of such novel method.
In this clinical trial the effect of the implant-abutment morphology (platform-switched vs platform matched) will be assessed in both soft tissue (soft tissue thickness) and hard tissue (marginal bone loss) outcomes. Several clinical predictors (initial implant position level, gingival biotype, abutment height and prosthetic emergence profile) will also be taken into account as modulating factors of the clinical outcome.
The purpose of this study is to compare whole body magnetic resonance (MR) imaging, whole body positron emission tomography (PET)/MR imaging, and (if available) PET/Computed Tomography (CT) imaging for the diagnosis of tumors in children and young adults. Sensitivities, specificities and diagnostic accuracies of the different imaging modalities will be compared for significant differences.
