purpose of this study was to assess morphologic features of alveolar bone
supporting maxillary premolars and molars and to determine the relationship
between maxillary sinus and teeth using cone beam computed tomography (CBCT). </span> <span lang="en" style="line-height:150%;" xml:lang="en"> </span> </p> <p> </p> <p class="MsoNoSpacing" style="text-align:justify;margin-bottom:2pt;line-height:150%;"> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us"> <b>Material and Methods </b> </span> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us">: In
CBCT scans of 100 patients, the thickness of both trabecular bone and cortical
plates surrounding 652 posterior teeth were measured and the relationship
between teeth and maxillary sinus was classified. </span> <span lang="en-us" style="font-size:14px;" xml:lang="en-us"> </span> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us">Also,
the angle between the teeth and the alveolar crest was measured. </span> <span lang="en" style="line-height:150%;" xml:lang="en"> </span> </p> <p> </p> <p class="MsoNoSpacing" style="text-align:justify;margin-bottom:2pt;line-height:150%;"> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us"> <b>Results </b> </span> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us">: </span> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us">Of the teeth examined, 25 % were in contact
with the inferior wall of maxillary sinus, 12% had penetrated the sinus and 63

mesiobuccally root of second molar teeth with 1.3 mm distance. </span> <span lang="en-us" style="line-height:150%;font-size:14px;" xml:lang="en-us">The
teeth which had thinnest bone configuration were maxillary first premolars. There
were no significant differences for measurements between sides and gender
(p>005). Buccal bone thickness and distance to the maxillary sinus floor
showed a negative correlation in molars (p˂0.001 and 0.003). </span> </p> <p class="MsoNoSpacing" style="text-align:justify;margin-bottom:2pt;line-height:150%;"> <span lang="en-us" style="font-size:14px;" xml:lang="en-us"> <b>Conclusion </b>: </span> <span class="FontStyle100" style="font-size:.9em;"> <span lang="en-us" style="font-size:14px;" xml:lang="en-us">In order to prevent possible complications, a
three-dimensional analysis of the posterior maxilla and maxillary sinus is
required before implant procedures to be performed on the maxillary posterior
