Panoramic X-Ray morphological features that describe the third molars' location when they close with the opposing teeth

Abstract

   Using 30 panoramic X-Rays of the jaws of individuals between the ages of 15 and 25, a scientific and applied study describes techniques for examining the morphological features of the maxillary system, including the position of the third molars. In addition to having a junction with the teeth antagonists, the third molars' crowns were fully erupted and nearly developed roots. The study looked at the third molars' angles of inclination (Weber technique), the mandibular angles' magnitude (Schwartz), the lower third molars' separations from the buttresses (Pankratova N. V.) and the mandibular angles' bisectors (Fischev S. B.), and the stages at which the third molars' roots formed (Demiryian). Determining the values of the indicators that describe the location of the third molars when they close with the tooth antagonists was the study's goal. Age is known to increase the mandibular angle's magnitude, the lower third molars' degrees of inclination, and the stages at which their roots form. Additionally, the third molars' angle of inclination increases as the mandibular angle and the phases of root production grow. The distance from the mandibular buttresses reduces as the lower third molars' phases of production rise, while the distance to the "Stress axis" lowers as the mandibular angle increases..
