Item Acesso aberto (Open Access) Análise de três técnicas de moldagem utilizando-se duas siliconas por condensação e uma silicona por adição(Universidade Estadual de Campinas, 1999-02-25) ANDRADE, Cícero Almeida de; SILVA, Frederico Andrade e; http://lattes.cnpq.br/2282864112869742The procedure ín the constructíon of a fixed brídged has always been long, dífficult and tedíous" New equípament and materiais has appered to facílítate this procedure, however a question sti!! remains: conciliate techniques and materiais with an suitab!e cost-benefit In thís way, lhe aím of this study was: evaluated 3 impressíon techiniques (unitary tray, double impression and simultaneous impression ) using addition and condensatíon sílícon materiais ( Express, 3M and Optosii/Xantopren )" Over a comparative mensuraments from complet arch model cast, we could conclude: consídering the techniques, the unítary tray technique had better results: the 3M material (condensatíon) showed statístically the most satisfactory results when the unitary tray was used.Item Acesso aberto (Open Access) Avaliação cefalométrica do perfil tegumentar e esquelético inicial e final de tratamento ortodôntico(Universidade Estadual de Campinas, 1999-07-06) ALMEIDA, Haroldo Amorim de; ALMEIDA, Maria Helena Castro de; http://lattes.cnpq.br/0770202080280415Was accomplished a study in 114 telerradiography of the head in lateral norm, of 57 Brazilian individuais, white, with Class 11, division 1 malocclusion (An.gle), submitted to orthodontic treatment according to the Tweed philosophy, with the purpose of evaluating the alterations to levei of the bony and soft-profile . The results demonstrated that among the angle Z and FMA an inverse correlation exists; when modifying the values of FMIA, Âng. Z suffers alterations of same degree and direction; altering the angle of the occlusal plan, they happen variations of similar value in FMA; any modification in ANB is accomplished by an alteration in AO-BO, of same magnitude and direction.Item Acesso aberto (Open Access) Análise comparativa da alteração dimensional de materiais de moldagem elastoméricos, através da técnica do casquete(Universidade Estadual de Campinas, 2000-09-18) ANDRADE, Cícero Almeida de; SILVA, Frederico Andrade e; http://lattes.cnpq.br/2282864112869742The present study assessed comparatively the dimensional change of four fluid-consistence elastomeric impression materiais (one addition silicone, two condensation silicones and one mercaptan) using the headcap technique. A metal cast (pattern) was made, enclosing two teeth with metal-crown preparation. On this cast, with a 0,3-mm metal relief, were obtained the headcaps using Neelon's technique (brush method). The impressions were carried out with a static-weight press, where a strength of 39.2 N (newton) was pressing the trays over the metal cast. The occlusal surfaces of the prepared teeth had cross-wise grooves. In the extreme of each groove there were small points where the reading started. The linear reading, in a comparing microscope, was initially done at the occlusal surface of each teeth distinctly, so following it was read matching the points between the two teeth. The results were statistically analysed and it followed that there were no statistically significant differences.Item Acesso aberto (Open Access) Métodos de avaliação do segmento posterior mandibular(Universidade Estadual de Campinas, 2002-11-18) ALMEIDA, Haroldo Amorim de; ALMEIDA, Maria Helena Castro de; http://lattes.cnpq.br/0770202080280415The aim of this study was to compare three evaluation methods of the space available in the jaw posterior segment: MERRIFIELD's (1978), RICKETTS (1976) and RICHARDSON's (1992); Sixty teleradiographs were laterally taken from the heads of sixty Brazilian leucodermas, with age ranging from 9 to 19 years oId. Ali patients presented Class II malocc1usion, division 1, Which were divided by sex into two groups: 30 male and 30 female. Based on the results of the present study it was conc1uded that there is an evident growth in the jaw posterior segment within the age of 9 to 19 years, with mean values of 10,21mm for the MERRIFIELD's method, 11,21mm for RICHARDSON's and 17,84mm for the RICKETTS method. Generally, independently of the evaluated method, it was verified that females present an earlier growth (12,17mm) than males (8,81mm), between 9 to 12 years old. For the correlation of the evaluated methods, there was no statistically significant difference by t test at the 1% level of significance (p = 0,01). The MERRIFIELD's method (1978) was the easiest to perform.
