Abstract

Aim: The aim of the study was to investigate the effect of cone-beam CT (CBCT) volume orientation on the proximity of maxillary sinus to the alveolar crest at dental implant sites. Materials and methods: CBCT images for 54 posterior maxillary implant sites were selected for the study. Vertical distance between the floor of maxillary sinus and the alveolar crest was measured in two different volume orientations: occlusal plane and mandibular base parallel to the horizontal plane. The measurements were repeated and compared using paired sample t-test. Results: The vertical distance between the floor of maxillary sinus and the alveolar crest was significantly greater when the CBCT volume was oriented with the mandibular base parallel to the horizontal plane (p ≤ 0.05). Conclusions: If the CBCT volume was oriented with the mandibular base parallel to the horizontal plane, this will result in increase of the vertical distance between the floor of maxillary sinus and the alveolar crest. Subsequently, this will lead to selecting longer dental implants. Clinical significance: CBCT volume orientation is paramount for implant planning at maxillary sinus area. Incorrect volume orientation might result in choosing implants with incorrect dimensions, this will lead to unacceptable complications at time of implants insertion.
