clusions often requires intrusion and retraction of the anterior segment, which, in turn, usually necessitate mechanical reinforcement of posterior anchorage.1 Intraoral devices such as transpalatal bars or Nance appliances2 can reduce the need to wear Class II elastics, but can cause mesial movement of the lower first molars and protrusion of the incisors.(More)
This study aims to report the willingness of different populations of high-risk couples to undergo preimplantation genetic diagnosis (PGD) for beta-thalassaemia as an alternative to prenatal genetic diagnosis (PND), and the willingness of infertile couples to undergo PGD for aneuploidies. An information sheet and questionnaire presenting PGD and PND(More)
PURPOSE Skeletal anchorage systems are increasingly used in orthodontics. This article describes the techniques of placement and removal of modified surgical miniplates used for temporary orthodontic anchorage and reports surgeons' perceptions of their use. PATIENTS AND METHODS We enrolled 97 consecutive orthodontic patients having miniplates placed as an(More)
This paper reports the results of 1428 beta-thalassemia chromosomes studied in Sicily during a hemoglobinopathy control program starting in 1983. Molecular screening was performed by direct restriction enzyme analysis, allele specific oligonucleotide (ASO) hybridization, reverse dot blot analysis (RDB) and, for the rare or new mutations, by direct(More)
The authors report the first case of mandibular distraction osteogenesis applied to a fibula microvascularized flap used to reconstruct an almost entire mandible. The technique and complications are described. The literature is reviewed. The biological and physiological process of bone elongation by Ilizarov's method is explained according new studies on(More)
Gustatory rhinorrhea consists of free discharge of thin mucus from the nose during ingestion or after other gustatory stimulus. At maxillectomy, the nerve fibers going both to the salivary glands of the palate and to the secretory glands of the nasal mucosa may be damaged. A misdirection between the regenerating fibers of these two groups produces gustatory(More)
Autologous bone grafting of alveolar clefts is a well recognized procedure. Calvarium represents an interesting donor site because of the absence of morbidity and the dimensional stability of this membranous bone compared with endochondral bone sources. The authors reponed their experiences with this type of grafting used in 17 patients. Referred to the(More)
The different sagittal, vertical or transversal skeletal dysmorphosis can be treated with orthodontic or orthopaedic appliances. Certain limits of treatment will be due to the age of the patient, the importance of the skeletal dysmorphosis, technical limits of the orthodontic appliances or the motivation and compliance needed from the patient. For this(More)
BACKGROUND In Italy, the autosomal recessive diseases beta-thalassaemia and sickle cell anaemia are so widespread that in some regions they can be defined as 'social diseases'. In this study, nine clinical applications of preimplantation genetic diagnosis (PGD) were performed for beta-thalassaemia and sickle cell anaemia on seven Sicilian couples and(More)
