Alveolar bone structures are mostly investigated in small animal models. The majority of these studies examined local influences on the alveolar bone, but only a few examined systemic influencing factors. The hypothalamic-pituitary axis is known to be essential for a vital bone balance. The aim of this study was to analyse the effects that selective hormone treatments have on alveolar bone structure and quality in a sheep model for alveolar bone loss, induced by hypothalamic-pituitary disconnection (HPD).
The bone implant contact (BIC) has traditionally been evaluated with histological methods. Thereupon, strong correlations of two-dimensional (2D) BIC have been detected between μCT and destructive histology. However, due to the high intra-sample variability in BIC values, one histological slice is not sufficient to represent 3D BIC. Therefore, our aim has been to correlate the averaged values of 3–4 histological sections to 3D μCT.
In this study, we experimentally evaluated whether complex, mature sutures can be separated using skeletal anchorage and light, continuous forces.
