Computer-aided system for morphometric mandibular index computation. (Using dental panoramic radiographs).

Objective: We propose and validate a computer-aided system to measure three different mandibular indexes: cortical width, panoramic mandibular index and, mandibular alveolar bone resorption index.

Study Design: Repeatability and reproducibility of the measurements are analyzed and compared to the manual estimation of the same indexes.

Results: The proposed computerized system exhibits superior repeatability and reproducibility rates compared to standard manual methods.

Histomorphological study of the bone regeneration capacity of platelet-rich plasma, bone marrow and tricalcium phosphate: Experimental study on pigs.

Introduction: Bone defects are rather common after oral surgery and may prove difficult to repair.

Objective: We provide a histomorphological analysis of the bone regenerative capacity of platelet-rich plasma at different concentrations and the extraction of platelet-rich bone marrow, compared with beta-tricalcium phosphate.

Methodology: We performed an experimental study on 8 pigs, in which we performed trepanations of the mandible in order to place the materials to be studied.
