Abstract:
Objective ??This?study?aims?to?examine?the?prevalence?and?diameter?of?the?bony?canal?structure?of?the?posterior?superior?alveolar?artery?(PSAA),?residual?alveolar?bone?height,?and?distance?of?its?inferior?border?from?the?alveolar?crest?using?cone-beam?computed?tomography?(CBCT). Methods ??CBCT?images?of?maxilla?in?116?patients?were?randomly?selected?from?patients?who?underwent?maxillary?sinus?augmentation?procedure?and/or?posterior?teeth?implant?therapy?from?April?2011?to?September?2012.?The?lower?border?of?the?bony?canal?to?the?alveolar?crest,?diameter?of?the?bony?canal,?and?residual?alveolar?bone?height?below?the?sinus?floor?to?the?ridge?crest?were?measured?from?CBCT?scans.?Data?were?presented?using?descriptive?statistics.?Results ??The?prevalence?of?the?bony?canal?was?75.14%(133/177).?The?mean?diameter?of?the?bony?canal?was?(0.96± 0.29)?mm.?The?residual?alveolar?bone?height?was?(7.14±3.64)?mm.?The?distance?of?the?bony?canal’s?inferior?border?from?the?alveolar?crest?was?(17.92±5.68)?mm.?No?statistically?significant?differences?between?the?right?and?left?sides?were?observed?(F=0.295,P>0.05).?The?mean?diameter?of?the?bony?canal?was?significantly?smaller?in?females?than?that?in?males(F=0.187,?P<0.05).?The?maxillary?alveolar?dimension?was?significantly?correlated?with?the?residual?alveolar?bone?height.?Conclusion ?The?results?from?this?study?suggest?that?CBCT?is?a?valuable?tool?in?evaluating?the?presence?of?the?bony?canal?of?the?PSAA?before?maxillary?sinus?surgery.
