Comparison of contact radiographed and stained histological sections for osseointegration analysis of dental implants – an in vivo study

Histology is still regarded as the gold-standard to determine bone implant contact (BIC) as a parameter representing implant stability. As the further processing of cut slices for contact radiography (CR) to stained and polished histological sections is time consuming and error prone, our aim was to assess agreement between CR and Giemsa-Eosin (GE) stained sections with regard to dental implants.

Evaluation of Immediate Dental Implant Augmented with Biphasic Calcium Phosphate Coated by Polylactide - co-Glycolide Versus to Immediate Dental Implant Only

Numerous bone grafts have been studied for augmentation of the healing outcomes of dental implants. The aim of this study was designed to compare the clinical and radiographic evaluation between immediate dental implant augmented with biphasic calcium phosphate (BCP) coated with polylactide -co- glycolide (PLGA) and immediate dental implant alone.

Comparative 3D micro-CT and 2D histomorphometry analysis of dental implant osseointegration in the maxilla of minipigs

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.

A HISTOMORPHOMETRIC EVALUATION OF THE EFFECTS OF PLATELETRICH FIBRIN AND RIFAMYCIN IN COMBINATION WITH AN ALLOGRAFT ON BONE AUGMENTATION WITH SIMULTANEOUS IMPLANT PLACEMENT IN RABBIT TIBIA

Dental implants protruding 2 mm were covered with dome-shaped stiff occlusive titanium barriers filled with demineralized freeze-dried bone allograft (DFDBA)+saline (7 rabbits), DFDBA + rifamycin (8 rabbits), or DFDB +PRF (8 rabbits). After 4 weeks, the animals were sacrificed, and undecalcified histomorphometric examination with toluidine blue staining was performed.
