Evaluation of the adaptation of zirconia-based fixed partial dentures using micro-CT technology

The purpose of this study was to investigate the effect of different intensities of exercise on the injury of the junction of bone and tendon. In this study, the feasibility of Micro-CT technology to calculate the thickness of fibrous cartilage band was investigated experimentally. Adult female New Zealand white rabbits were selected as the study subjects and randomly selected into 4-week cyclic load group (n = 8) and 8-week cyclic load group (n = 8). Among them, left hind limb was used for experiment and right hind limb was used as blank control. The results showed that the tissue morphology of the bone tendon junction was changed in each load group, while the tendon cell density was significantly increased in the high-exercise load group, and there was no significant difference in the thickness of the fibrous cartilage band. Micro-CT calculation results of bone mass and trabecular bone showed no significant difference between the experimental group and the control group. Therefore, it can be concluded that the intervention of different strength load train and rest on the injury of the junction of the patella and tendon can change the fine structure of the bone, but not the tissue changes of the junction of bone and tendon, and the bone reconstruction and recovery ability is stronger than the junction of bone and tendon.

First Time

The species-rich giant pill-millipedes (Sphaerotheriida) often represent a microendemic component of Madagascar’s mega-invertebrate fauna. Of the chirping genus Sphaeromimus de Saussure & Zehntner, 1902, ten species have been described. Here, we describe two new species of Sphaeromimus integratively, combining light microscopy, scanning electron microscopy, DNA barcoding and micro-CT technology for the first time in a taxonomic description of a giant pill-millipede. S. kalambatritra sp. nov. and S. midongy sp. nov. are the first giant pill-millipedes collected and described from the mountainous rainforests of Kalambatritra and Midongy. Both species show island gigantism compared to their congeners. Our analysis of the mitochondrial COI gene shows that the two species are related to one another with a moderate genetic distance (9.4%), while they are more closely related to an undetermined specimen from the forest of Vevembe (6.3% and 8.4%). They stand in a basal position with S. ivohibe Wesener, 2014 and S. musicus (de Saussure & Zehntner, 1897). The four aforementioned species share a high number of stridulation ribs on the male harp. Our micro-CT analysis provides a look into the head of S. kalambatritra sp. nov. and shows that non-destructive CT methods are a useful tool for studying the inner morphology of giant pill-millipedes.
