A sample of 54 patients (selected from a group of 289 patients) possessed a range of Little’s Irregularity Index values for the upper and lower dental arches between a minimum of 6.5 and a maximum of 13.5 at T0, and corresponding final values no greater than 2 and hence of minimal irregularity. The 54 patients were subdivided into three groups according to the type of brackets used in their treatment: Group 1 was composed of 24 patients treated using the self-ligating technique, Group 2 of 15 patients treated using a conventional straight-wire technique (Roth) and Group 3 of 15 patients treated using the standard edgewise technique. Cephalometric tracings were performed on laterolateral teleradiography. Group 1 value was found to be nonsignificant, whe...

While space closure seems to be the safer option for avoiding long-term sequelae, especially progressive infraocclusion, the latest improvements in implanto-prosthodontics, if coupled with comprehensive orthodontic pretreatment, can achieve excellent esthetic and functional outcomes at least in the mid to long term, provided that patient compliance is guaranteed.

Scientific evidence suggests that posterior crossbites, mild to moderate Class III, as well as certain Class II malocclusions, open bites and arch length discrepancies can benefit from simple, but efficient interceptive therapy. Objective: To summarize the existing evidence-based literature on early orthodontic treatment, and to illustrate its application and effectiveness by showcasing multiple clinical examples. Conclusion: Early short-term interceptive orthodontic treatment with simple appliances, in the deciduous or early mixed dentition phase, can efficiently correct certain malocclusions and help to either reduce the complexity or even avoid the necessity of complex and expensive procedures during puberty. For certain patients with significant arch length discrepancy the concept of serial extractions should be part of the ort...

The few published case reports about orthodontic treatment for this disorder have only described space opening for prosthodontic replacement of a central incisor. In contrast, the present patient was treated with extraction of the solitary median maxillary central incisor and orthodontic space closure with subsequent minimally invasive restorations in order to avoid looming esthetic or periodontal sequelae associated with any type of fixed bridgework or implant-borne crowns in the sensitive maxillary anterior area-which is especially indicated in young girls with a hyperdivergent growth pattern.

Besonders in den letzten Jahren ist es allerdings in Vergessenheit geraten, da das sich ständig erweiternde kieferorthopädische Therapiespektrum neue Möglichkeiten zur Platzbeschaffung umfasst. Die eigentliche Herausforderung in der Kieferorthopädie besteht jedoch nicht in der unbedingten Vermeidung von Extraktionen, sondern in der Wahl der geeignetsten Behandlungsstrategie für den individuellen Patienten unter Berücksichtigung von kraniofazialer Struktur und parodontalen Verhältnissen, mit dem Ziel, möglichst optimale dentale Beziehungen unter Wahrung der Gesichtsästhetik zu erreichen. Aus diesem Grund verdient die gesteuerte Extraktiontherapie eine kritische Reevaluation, da sie sowohl die Dauer der aktiven Behandlung, die Beeinträchtigung des Patienten durch Geräte und natürlich auch die Kosten reduziert und somit eine ausgezeichnete Stra...

Aim: To cephalometrically compare soft tissue changes produced either by maxillary premolar extraction, tooth-borne Pendulum appliance or bone-borne MGBM appliance. Materials and Methods: Both pre- (T1) and post-treatment (T2) lateral cephalograms of 89 skeletal Class II patients (36 M, 53 F), treated during pubertal growth spurt, were retrospectively selected. Three groups were formed based on the therapy performed: 30 patients had been treated with maxillary first premolars extraction (U4), 31 patients with a conventional tooth-borne distalizing with Pendulum appliance (PA), and 28 patients with a skeletally anchored distalizing appliance (MGBM). Soft tissue was analyzed comparing upper (UL) and lower (LL) lip’s points with regard to True Vertical Line (TVL) and Esthetic plane (E-plane). Skeletal and dental values ...

Fifteen months after replantation of the teeth, all showed severe root resorption with apical inflammation and had to be extracted. After compensatory removal of the maxillary left central incisor, all 4 extraction sites were closed within 20 months of active orthodontic treatment to avoid implant-prosthodontic replacement. By sequential extraction of the 2 hopeless replanted equilateral mandibular left incisors and common-sense management of straightwire mechanics, it was possible to move the right central incisor across the mandibular midline and close the large space completely. To our knowledge, no case report about orthodontic closure of 2 adjacent extraction spaces in the same quadrant has been published.

Art is modified by technology, just as technology is made from art and creates new ways of doing art. This fusion takes place positively in several chapters of this world, especially in the one involving the face: the treatment of dentoskeletal deformities through orthognathic surgery. Surely, the one who has all technology and is limited in relation to the arts, will definitely not achieve excellence of results. And it is here that enters Simonas-equipped with Technology (science) and Art (sense). Coming from a new country, Lithuania, which suffered with war, we may consider Simonas a revolutionary of the knowledge of ideal faces. Capable of balancing himself between technology and art, he knows how to read a face very well and has the most appropriate numbers for the three-dimensional movements of the jaws, teeth and soft tissues. Born curious, with a high intellect and provided with a big heart, Simonas is loved all over the world, on the five continents. For those who do not know him yet, may this interview bring some of histhinking and surgical philosophy. Open your wings a lot, Simonas, your flight will be even higher! Arte e tecnologia se fundem no mundo cirúrgico contemporâneo. A arte é modificada pela tecnologia, assim como a tecnologia se faz a partir da arte e cria novas formas de fazê-la. Essa fusão se faz valer positivamente em vários capítulos desse mundo, principalmente naquele que envolve a face: o tratamento das deformidades dentoesqueléticas por meio da cirurgia ortognática. Absolutamente, aquele que dispõe de toda tecnologia e se limita da arte ficará sem conhecer resultados verdadeiramente de excelência. E é aqui que entra o Simonas, equipado com tecnologia (ciência) e arte (senso). Vindo de um país novo, a Lituânia, e sofrido pela guerra, consideremos o Simonas uma revolução do conhecimento da face ideal. Capaz de equilibrar-se entre a tecnologia e a arte, ele sabe ler muito bem a face e ter os números mais adequados para os movimentos tridimensionais dos maxilares, dentes e tecidos moles. Curioso nato, com um alto intelecto e provido de um grande coração, Simonas se faz querido pelo mundo, nos cinco continentes. Para aqueles que não o conhecem ainda, que esta entrevista possa trazer um pouco do seu pensamento e filosofia cirúrgica. Abra muito suas asas, Simonas, seu voo será ainda mais longo! Lucas Senhorinho Esteves (interview coordinator / coordenador da entrevista) » Simonas is graduated from the Kaunas University of Medicine and acquired his dental degree in 2000. » He completed his training in Oral Surgery (2003) and Maxillofacial Surgery (2006) at Vilnius University. » In 2008 he acquired his Medical degree and became a double qualified oral and maxillofacial surgeon. » He passed the exams and became a member of the Royal College of Surgeons of Edinburgh in 2005. » In 2009, he was awarded a PhD degree by Riga Stradins University (Latvia). » Consultant in Oral and Maxillofacial Surgery at Vilnius University. » Private practice S'OS (Simonas Grybauskas' Orthognathic Surgery). » Visiting professor at University of Ferrara, Italy. » Author of scientific publications. » A professor who has delivered more than 100 lectures on orthognathic and reconstructive surgery in international conferences and courses. » A member of the Lithuanian Association of Maxillofacial Surgery since 2002, a member of the Baltic Association of Maxillofacial and Plastic Surgery since 2003, and a member of the European Association for Cranio-Maxillofacial Surgery since 2005. » Host and director of two major international events-the 1 st and the 2 nd Baltic Sea Conferences on Orthognathic Surgery and Orthodontics, in Vilnius in 2009 and in Riga in 2015. » Dedicated, for most of his time, to orthognathic and reconstructive surgery and development of virtual surgical planning techniques.

A series of 9 posttreatment intraoral frontal photographs was presented to 87 orthodontists, 100 general dentists, and 100 laypersons. The photographs represented dentitions with either single-tooth implants or canine substitutions for missing maxillary lateral incisors and dentitions with no missing teeth. Each photograph was rated independently by assigning a number between 1 (best) and 5 (worst) for a series of 7 bipolar adjectives. Two-way analysis of variance and Tukey post hoc tests were performed to assess differences in intragroup and intergroup preferences for the various treatment options. Subsequen...
