Is PRP useful in alveolar cleft reconstruction? Platelet-rich plasma in secondary alveoloplasty
2009
Objective: Cleft lip and palate is a congenital facial malformation with an established treatment protocol. Mixed dentition period is the best moment for correct maxillary bone defect with an alveoloplasty. The aim of this surgical procedure is to facilitate dental eruption, re-establish maxillary arch, close any oro-nasal communication, give support to nasal ala, and in some cases allow dental rehabilitation with osteointegrated implants. Study design: Twenty cleft patients who underwent secondary alveoloplasty were included. In 10 of them autogenous bone graft were used and in other 10 autogenous bone and platelet-rich plasma (PRP) obtained from autogenous blood. Bone formation was compar…
Cervical vertebral maturation and its relationship to circum-pubertal phases of the dentition in a cohort of Portuguese individuals
2019
Background To explore the relationship between individual skeletal maturity as assessed by Cervical Vertebral Maturity method (CVM), circum-pubertal phases of the dentition (early mixed, intermediate mixed, late mixed and early permanent) and chronlogical age in a cohort of Portuguese individuals. Material and Methods This was a retrospective cross-sectional study. The sample comprised 300 Caucasian Portuguese subjects aged 6 to 16 years, (137 boys and 163 girls). All the participants had good quality panoramic and lateral cephalometric radiographs. Subject skeletal maturity was evaluated using the CVM method. Dental age evaluation was determined by using panoramic radiographs and dental ca…
Study of the influence of crossbite on the size of the apical area in a child population by analyzing panoramic X-ray
2018
The apical area is the space in the maxillary bones that contains teeth during formation and is subsequently occupied by the apices of the permanent teeth. Its dimensions are easy to perceive and determine by observing a panoramic X-ray. Our objective was to analyze the influence of crossbite on the size of the anterior and mesial apical area in Caucasian children. Based on the ortopantomograph of 353 patients in mixed dentition and crossbite, the sizes of the apical areas of the four hemiarches were studied using the Tps Dig Version 2® computer program. These data were subjected to statistical analysis using the SPSS 22.0 for Windows program and applying the methods of descriptive statisti…
ANTERIOR OPEN BITE TREATED WITH E F APPLIANCE: A CASE REPORT
2014
Aim. Current trends in pediatric orthodontics aim to identify incorrect development of occlusion and medium/lower facial third as early as possible. Functional appliances are a popular type of device used for treating malocclusion in patients who are growing. Among the functional orthodontic devices intended for this purpose, “Education Functional” is highlighted. It was developed by Dr. Daniel Rollet. In fact, in the occlusal alterations, early preventive treatment with elastodontic devices resulted in avoiding dysfunctional forces from acting on the skeletal pattern, thus reaching a balance between bone basis and muscular components. This report describes a clinical case of a patient (9-y…
The influence of crossbite in early development of mandibular bone asymmetries in paediatric patients
2017
BACKGROUND All authors agree that posterior crossbite is a malocclusion that affects mandibular growth and may lead to skeletal asymmetry but there are few data on which age these modifications are easily quantifiable. MATERIAL AND METHODS For this study, the researchers used x-ray records of 217 children between 6 and 9 years of age, in the mixed dentition stage and with unilateral posterior crossbite. All the horizontal variables were traced and evaluated by the principal researcher, using the tpsDig version 2 computer program. Subsequently, a descriptive and statistical analysis was carried out, using the SPSS 17.0 for Windows program. RESULTS AND DISCUSSION After analysing the vertical …
