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

2012

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. Moreover, the time required to perform the measurements using the proposed method is negligible compared to perform the measurements manually. Conclusions: We have proposed a very user friendly computerized method to measure …

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

2009

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 -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. Using an electron microscope, we observed the samples obtained and took a series of photographs in order to analyze the samples through a gray-scale histogram system. Results: Ossification phenomena were present in 96% …

Histological differences in the adherence of connective tissue to laser-treated abutments and standard abutments for dental implants. An experimental…

2017

Background The goal of the current study is to assess the difference in connective tissue adherence to laser microtextured versus machined titanium abutments. Material and Methods Six patients were selected and each of them received 2 implants, one combined with a laser treated abutment and one with a machined abutment. After three months, the abutments were retrieved together with their surrounding gingival tissue for histological analysis. Qualitative and quantitative evaluation of microscopical images was performed to assess the presence or absence of adherence between the soft tissues and the abutment, and the percentage of soft tissue adhered to the two different surfaces. Results Inti…
