ABSTRACT
Cone-beam computed tomography(CBCT) was used to analyze the anatomic morphology of maxillary canine fossa of different sagittal skeletal patterns patients;implants of various dimensions were virtually placed into the maxillary premolars region.The relationships among maxillary canine fossa and implant were analyzed.The depth of the maxillary canine fossa was(4.33±0.73),(3.77±0.58),(5.18±0.93)mm in the 1st premolar region of class Ⅰ,Ⅱ and Ⅲ respectively.The depth of the maxillary canine fossa was(3.20±0.63),(2.81±0.58),(3.90±0.79)mm in the 2nd premolar region of class Ⅰ,Ⅱ and Ⅲ respectively.There were no significant statistical differences in genders,sides,and loss of tooth.And there were significant statistical differences in three classes(P<0.05).The length of the implants was (10.30±1.70)mm(d=3.3 mm) and (8.77±1.58)mm(d=4.1 mm) in the 1st premolar region and (8.09±1.51)mm(d=3.3 mm),(6.69±1.35)mm(d=4.1 mm) in the 2nd premolar region in patients with teeth and buccal perforation;the length of the implants was (8.98±1.54)mm(d=3.3 mm) and (7.67±1.52)mm(d=4.1 mm) in the 1st premolar region and(7.09±1.59)mm(d=3.3 mm) and (5.79±1.34)mm(d=4.1 mm) in the 2nd premolar region in patients with tooth loss,respectively.There were significant statistical differences in loss of tooth(P<0.05).Analyzing of spatial relationships among maxillary canine fossa and implants of different sagittal skeletal patterns patients especially class Ⅲ patients,by using CBCT has important significance in guiding dental implants.
