Maxillary sinus floor and its relation to premolar
Description and comparison: The paraconid is present mesially and entoconid distally in the third premolar
The ultrasonographic determination of the position of the mental foramen and its relation to the mandibular premolar
 Hence, in maximum anchorage premolar
extraction cases, canine distalization usually takes 6-9 months, contributing to an overall treatment time of 1.5-2 years.
In 64 cases selected from the database, the most commonly observed position of the MF was apical area of second premolar
and straight pattern of emergence was found in most of the cases.
All impacted molars were classified according to Pell and Gragory classification 20 whereas for premolars
and canines classification given by Yamamoto21 was used.
Within the limitations of the present study, it can be concluded that direct cuspal coverage with resin composites transfers less stress to the enamel than restorations without cuspal reduction and appears to be a reliable extracoronal reinforcement method in restoring maxillary first premolar
with missing palatal cusp.
Conventional pendulum anchors from the palatal tissue and upper premolars

This study showed an increase in maxillary inter-canine width, inter 1st premolar
width, inter 2nd premolar
width and inter molar arch width (Table 1).
All the clasp groups (20 transparent polyamide, 20 pink polyamide, 20 Co-Cr) were divided into 2 subgroups (n=10), according to the type of tooth (molar or premolar
