Prevenzione delle malocclusioni : indicazioni di base
No full textObjectives: The aim of this study is to show the most frequent risk factors for malocclusions and how to prevent them. Material and methods: The international literature regarding oral functions, parafunctions, and bad habits promoting malocclusions was analysed. Results: All parafunctions and oral habits, if not treated early, can lead to alterations of the orofacial growth. Conclusions: Early detection and treatment of oral habits and parafunctions is recommendable to avoid either the onset of a new malocclusion or the worsening of a preexisting one. Therefore, it is necessary that clinicians who periodically control children (e.g., pediatrician, dental hygienist, general dentist) can identify bad habits and refer their patients to the orthodontist

No full textPrevenzione della carie dentaria e della malattia parodontale durante la terapia ortodontica fissa
No full textObjectives: This work describes the most frequent risks related to fixed orthodontic treatment (i.e., caries and periodontal disease) and how to prevent them. Materials and methods: The authors reviewed the most recent literature regarding the relationship between fixed appliances, dental caries, and periodontal diseases in orthodontic patients. The most useful preventive systems were analyzed as well. Results and conclusions: The risk of caries and periodontal disease is higher in orthodontic patients with fixed appliances. The prevention of these pathologies relies on a thorough oral hygiene, periodic applications of fluoride and/or chlorexidine (varnishes, mouthwashes, sprays, etc.), and regular supervisions by the oral hygienist and the orthodontist
Long-term follow-up of UCLP patients : surgical and orthodontic burden of care during growth and final orthognathic surgery need
No full textObjective: The goal of this study was to evaluate the craniofacial morphology at 5 and 10 years of age and at the completion of growth, the need for final orthognathic surgery, and the orthodontic burden in a sample of patients with unilateral cleft lip and palate consecutively treated by the same surgeon with the same two-step protocol.
Design: A sample of 62 adult patients with unilateral cleft lip and palate was retrospectively collected (mean age, 17.5 years). Lateral cephalograms at three time points were traced. The need for orthognathic surgery was assessed, subdividing the sample into an orthognathic surgery group and non–orthognathic surgery group. Time and modality of orthodontic treatment were recorded.
Results: Cephalometric values related to maxillary growth (SNA, SNAns) and maxillomandibular relation (ANB, NAPg) were significantly different between the two groups already at 5 and 10 years of age. All patients presenting an ANB smaller than 2° at 5 years needed a Le Fort I osteotomy. Mandibular protrusion (SNB, SNPg) was not different at 5 and 10 years, but was different at the completion of growth. Patients with the same initial maxillomandibular relation did not show better growth when subjected to earlier or longer orthodontic treatment.
Conclusion: Patients needing final jaw surgery had a more severe skeletal discrepancy during early childhood. The ANB angle at 5 years allowed doctors to identify 45% of the need for orthognathic surgery. The final craniofacial pattern does not seem to change significantly with early or prolonged orthodontic treatment
