[The disposition of the apices of the roots of multirooted teeth in the alveolar processes of the upper jaw].
Specific features of the disposition of root apexes of premolars and molars in the alveolar process of the upper jaw were studied in 148 skulls and 67 tooth-jaw cuts. The least thickness of the alveolar process was found to be at the level of the first premolar (10,41 +/- 0,33 mm), and the greatest--at the level of the first molar (14,075 +/- +/- 0,456 mm). Strong correlation of the alveolar process was established between the levels of the premolars and the last two molars. The distance from the apexes of cheek roots of the first molar to the bottom of the maxillary sinus is 2,05--2,92 mm, and the palatal roots -- 2,02 mm. On roentgenograms the molar roots are often projected on the sinus bottom.
