“…[17][18][19][20][21] The analysis of results, independently from the considered arch, shows that the discrepancies reported for the virtual diagnostic protocol are, on average, lower than those obtained in the group receiving the nonvirtual diagnostic protocol. Presurgical templates allow the orthodontist to more easily achieve the objectives set in the diagnostic phase.…”

The precision of presurgical orthodontic diagnostic protocol plays a key role for the success of orthognathic surgery.Recently, the introduction of cone beam computed tomography and the development of digital technologies led to the possibility to create new virtual protocols of diagnostic protocol.The purposes of this study were to describe the virtual presurgical orthodontic diagnostic protocol experimented by the Orthodontics Department of the University of Milan and to assess its reliability by comparing it with the nonvirtual protocol.The study sample was a group of 18 adult patients who required surgical correction of skeletal asymmetric class II or III malocclusion: 9 of them were subjected to the virtual diagnostic protocol, whereas the other 9 were subjected to the traditional one. A comparison between the 2 methods was carried out by evaluating the degree of the discrepancy between setup and presurgical models in both groups. The values of maximum positive deviation, maximum negative deviation, mean deviation, and standard deviation that characterize the points of the superimpositions were considered.An optimal superimposition (>75%) between the scanning of the setup and presurgical models was obtained for all subjects except for 2 patients with asymmetry. The analysis of the punctual deviation variables did not show statistically significant differences between the techniques.The study suggested a high precision for both diagnostic protocols, and the reliability of the 2 methods is comparable. However, the virtual protocol has several advantages such as quantity of information obtainable, repeatability, and speed of execution.

“…A slight mandible clockwise rotation aids in the resolution of the sagittal discrepancy. It is important to underline that the correction of skeletal class III occlusion happens during the active phase of therapy, while the correction of skeletal class II occlusion happens during the retention phase [ 31 , 32 ]. This change agrees with the findings in the studies of Wertz [ 7 ], Cleall [ 11 ], Linder-Aronson and Lingren [ 21 ], Davis and Kronman [ 33 ], Hicks [ 34 ], and Gardner and Kronman [ 35 ].…”

BackgroundThe aim of this retrospective study was to cephalometrically evaluate the skeletal and dental effects of the transverse sagittal maxillary expander (TSME), for the correction of sagittal and transverse maxillary deficiency in class I, II, and III malocclusions.MethodsThe sample for this retrospective study included 45 patients (mean age, 8.4 years; 26 females, 19 males; 15 skeletal class I subjects, 15 skeletal class II subjects, and 15 skeletal class III subjects) with maxillary bilateral cross-bite.For each patient, a lateral cephalogram was obtained before treatment and at the end of the retention period. Changes in the groups during the observation period were calculated, compared, and statistically analyzed with a t-test.ResultsThe cephalometric values before T0 and T1 showed significant changes.ConclusionsThe TSME can produce skeletal changes due to the transverse force and sagittal effects on the maxillary alveolar process. These modifications have benefic effects in classes I, II, and III. The data obtained in this study permit us to underline the fact that TSME can be used in all of the skeletal classes, with good vertical and sagittal results.

Among the most common malformations observed in the oral cavity are cleft lip/palate and malocclusions, being this last one considered by the World Health Organization, the third public health problem.Malocclusions include the anterior open bite, a change in the vertical plane, that can be of two types: dental anterior open bite and skeletal anterior open bite. Cleft lip and cleft palate are the most common congenital malformations at birth. These malformations result from a failure in the normal craniofacial development process, which requires the coordination of a complex series of events. From the embryological point of view, the cleft lip/palate is a consequence of the failure of the first superior branchial arch to complete fusion with the frontonasal process during pregnancy.All these malformations result from the interaction of both genetic and environmental factors. Among the environmental factors involved in the development of malocclusions are deleterious habits, mouth breathing and trauma. Several genes involved in the development of facial bones, muscles and teeth are also responsible for the development of malocclusions. In the same way, clefts development is a multifactorial trait where multiple genes are involved as well as environmental factor like alcohol consumption, tobacco, exposure to pesticides or toxic solvents, in a complex interaction.All these factors may jeopardize the normal functioning of the stomatognathic system and the consequent quality of life of the patient. The purpose of this study was to review the literature concerning the genetic and environmental aspects involved in the development of these malformations.
