“…7). It should be noted that although the screw should optimally be inserted in the bone at a right angle (90 degrees), the allowed deviation from this value ranges even 20-45 degrees [22]. The most typical screw configuration involves inserting 3 screws DZISIAJ Dzisiaj w chirurgii ortognatycznej wybór rodzaju zespolenia odłamów kostnych należy najczęściej do operatora.…”

“…7). Pamiętać należy, że optymalny kąt wprowadzenia śruby do kości wynosi 90°, jednak są dopuszczalne odchylenia nawet 20-45° [22]. Najczęstszy układ to umieszczenie 3 śrub na górnym brzegu odłamów lub 2 na górnym i 1 poniżej kanału żuchwy, ze wskazaniem na ten drugi ze względu na właściwo-ści biomechaniczne zespolenia (ryc.…”

“…Na literatura, verificamos vários tipos de substratos disponíveis que podem ser utilizados em ensaios biomecânicos, como a mandíbula humana cadavérica (Ardary, 1989;Throckmorton et al, 1992;Schwimmer et al, 1994;Kohn et al, 1995;Kim et al, 1995), mandíbula de animais, como cordeiro, costela bovina, (Foley;Beckman, 1992;Uckan et al, 2001;Nissenbaum et al, 1997;Gomes et al, 2003), além de réplicas sintéticas de poliuretano ou mesmo madeira (Maureret al, 1999;Kohn et al, 1995;Kim et al, 1993;Foley;Beckman, 1992;Murphy et al, 1997;Erkmen et al, 2005aErkmen et al, , 2005b.…”

“…Sabe-se que não há diferenças significantes entre as propriedades mecânicas do osso fresco e osso congelado quando armazenado a -20 º C (Evans, 1973), desde que retorne à temperatura ambiente antes do teste (Ashman e Van Buskirk, 1987). Com base nestes achados e concordando com outros autores (Foley;Beckman, 1992;Nissenbaum et al, 1997;Uckan et al, 2001;Gomes et al, 2003), mantivemos as mandíbulas congeladas. As mandíbulas foram envoltas em compressas com soro fisiológico, colocadas em sacos plásticos, onde se tomou cuidado para que elas permanecessem em estado úmido e hidratadas, sendo então congeladas e armazenadas a -20º C, corroborando com o proposto por outro estudo (Pimentel, 2012).…”
