Porous scaffolds have been the subject of numerous investigations, especially for broken and damaged parts of the facial bone. The goal of this study was to look into the biological, experimental, and numerical study of the mechanical properties of porous scaffolds under static loading conditions.Materials & Methods: In this study, a bone scaffold of polycaprolactone- Fluorapatite (PCL / nFA) nanocomposite materials containing (0, 10, 20, 30 %wt.) Fluorapatite nanoparticles was designed and manufactured using a 3D printer with Fused Deposition Modelling (FDM) process. The scaffolds were designed in SolidWorks software with 70% porosity and then transferred to Abaqus software for simulation.Results: In addition, following 28 days of immersion in the simulated body fluid, the bioactivity test of pure and composite scaffolds showed that the PCL /20nFA composite sample produced the most apatite on the surface. DAPI staining and fluorescent microscopy observation, confirm cell viability on the 3D printed scaffold.Conclusion: The Von Mises stress and compressive test simulations revealed that the porous scaffold model may be used for maxillofacial bone replacement and has good mechanical strength and stability.","PeriodicalId":221865,"journal":{"name":"Journal of Isfahan Dental School","volume":"14 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131355447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate the match between smile design and personality traits of patients applying for smile design.Materials & Methods: This is a descriptive-analytical study. Standard photographs in three different modes of rest, gentle smile, and full smile were taken from 104 patients aged 30-18 years referred to the School of Dentistry of the Islamic Azad University of Isfahan in 2016 for smile design. Patients were given a questionnaire about temperament and an interview questionnaire for understanding their dental needs. The photos were checked by one professional observer and classified according to the Visagism concept and the photos were analyzed with the results of the questionnaire and the interview form.

The most consistent in these 2 factors was Phlegmatic temperament (81.1%).Conclusion: Since there is a significant relationship between smile design and personality, it is recommended that in reconstructing a smile dentists should not limit themselves to aesthetic aspects from a dental point of view, but by creating a patient's psychological evaluation, create an esthetic smile plan in harmony with patients' psychological characteristics.","PeriodicalId":221865,"journal":{"name":"Journal of Isfahan Dental School","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131963469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
