Innovation by Computer-Aided Design/Computer-Aided Manufacturing Technology: A Look at Infection Prevention in Dental Settings
Full text linkRecent data indicates limited awareness and compliance on infection prevention procedures by dental offices and by dental laboratories. Guidelines for infection prevention in dentistry have been published by Centres for Disease Control and Prevention since 2003; the section "IX-Special consideration" includes a subsection concerning the prevention in dental laboratories, but it has not been modernised in later versions to fit the needs of traditional and computer-aided technology. Traditional techniques required disinfecting items (impression, chewing waxes, and appliances) with well-suited products, which are also chosen for limiting impression changes or appliance deterioration. Effective procedures are available with difficulties. Some of these contain irritant or non-eco-friendly disinfectants. The transport of impression, to dental laboratories, is often delayed with limited precautions for limiting cross-infection. Gypsum casts are frequently contaminated mainly by bacteria and their antibiotic-resistant strains and even stored for long periods during dental implant supported restoration and orthodontic therapy, becoming a hidden source of infection. Nowadays, computer-aided design/computer-aided manufacturing technology seems to be an interesting way to promote both business and safety, being more comfortable for patients and more accurate than traditional technology. A further advantage is easier infection prevention since, for the most part, mainly digital impression and casts are not a source of cross-infection and the transport of contaminated items is reduced and limited to try-in stages. Nevertheless, a peculiar feature is that a digital electronic file is of course unalterable, but may be ruined by a computer virus. Additionally, the reconditioning of scanner tips is determinant for the optical characteristics and long term use of the scanner, but information for its reconditioning from producers is often limited. This study focuses on some critical points including (a) insufficient guidelines, (b) choice of proper procedure for scanner reconditioning, and (c) data protection in relation to patient privacy
Preparazione ortodontica per il trattamento delle II Classi da retrusione mandibolare.
No full textThis research aims to introduce a therapeutic protocol for patients with Class II skeletal malocclusion caused by mandibular retrusion. The Authors emphasize the benefits of orthodontic therapy in removing dental interferences before using a functional appliance. Especially in Class II skeletal malocclusions with madibular retrusion, the aim of the first part of orthodontic treatment should be the correction of occlusal relationships interfering with the development of the disc-condylar complex. It is therefore necessary that orthodontic therapy remove trasversal and vertical premature contacts altering mandibular position. Furthermore this preliminary correction allows the establishment of a more favourable environment that will improve the result of functional therapy
Facial aesthetics and childhood
Full text linkIM:
The aim of the study is to evaluate attention and perception of parents about children's facial aesthetics, the paediatrician's role in early diagnosis of these problems and the areas of the face considered as the most important from an aesthetic point of view.
METHODS:
The study was carried out collecting 1214 questionnaires at paediatricians waiting room in the North of Italy.
RESULTS:
Most parents showed attention toward craniofacial deformities of their children and considered the paediatrician's role as very important in early diagnosis. Profile was considered more important than the front view and face's areas felt as the most important were denture, eyes and nose.
CONCLUSION:
Despite public opinion, adults are concerned not only about the general health and growth of their children, but also about their facial aesthetics. They, in fact, not only judge aesthetics of the whole face, but also discriminate different views and specific areas of the face. They require, for early diagnosis of dentofacial problems, skilled attention from the paediatrician
Orthodontics and Moebius syndrome. An observational study
Full text linkBACKGROUND:
Moebius syndrome is a rare condition characterized by bilateral facial and abducens nerve paralysis. The aim of this study is to evaluate the main orthodontic features and the frequency of associated clinical characteristics in patients with Moebius Syndrome (MS).
METHODS:
According to Terzis classifications, 58 patients with MS aged 8 months to 46 years old underwent orthodontics and clinical examination.
RESULTS:
Strabismus, upper and lower limb malformations, lip and palatal cleft were frequently associated with MS. Reduced TMJ movements were noted (48%). Cephalometric analysis did not allow identifying a typical facies and a characteristic cephalometric pattern; we have noticed a higher prevalence of Class II (56%) with micrognathia and excessive maxillary development probably due to the lack of lip seal. Early treatment is recommended, with a multidisciplinary approach to reduce the impact of sequelae on the lives of MS patients or their families.
CONCLUSIONS:
Early treatment is recommended, with a multidisciplinary approach to diminish the impact of sequelae on the lives of MS patients or their families
