The maxillary canine had more severe horizontal (P = 0.001) and angular (P = 0.003) impactions in females. Tooth agenesis was associated with less severe horizontal impaction (P = 0.041) in the ...
The maxillary left first premolar site was analysed for a fixation screw, and sufficient bone was noted (Figs. 8a-d). It was determined that no angular or linear correction would be needed. The ...
Ong, H.B. and Woods, M.G. (2001) An Occlusal and Cephalometric Analysis of Maxillary First and Second Premolar Extraction Effects. The Angle Orthodontist, 71, 90-102. has been cited by the following ...
The “perforation" category of maxillary sinus perforation was highest in the left second premolar (21.9%). Associations were found between buccal bone perforation and sagittal root position in the ...
Cephalometric analysis revealed skeletal Class I relationship (ANB = 1 o). Considering occlusal plane angle values (SN.Ocl = 33 o), mandibular plane (SN.GoGn = 42 o) and Y axis (Y-axis = 62 o), a ...
Radiography (Figure 2) revealed a complex orthodontic case with bilateral impacted maxillary second premolars. The lack of space in the maxillary, particularly on the left side (7 mm) compared to the ...
The results of this study showed that the buccal displacement of the teeth gradually decreased from the first premolar to the second molar when the clear aligner was used in the overall expansion of ...
Specifically, the maxillary second premolar buccal cusp is similar in height to the lingual cusp, while the mandibular second premolar appears round. The maxillary first molar and the second molar are ...
The CT image of the first patient shows that the implant was displaced in the left nasal cavity but not in the maxillary sinus (a-c). The implant of the right premolar area, which appeared to be ...
Missed canals were more frequently identified in maxillary second premolars (21.8%) than first premolars (11.4%) (P = .044). The researchers concluded that Multiple factors are associated with primary ...
An extracted maxillary second premolar was scanned to produce intact (IT) 3D model. Models were designed with an occlusal conservative access cavity (CAC) with different coronal defects; mesial defect ...
To evaluate the influence of the loss of coronal and radicular tooth structure on the biomechanical behavior and fatigue life of an endodontically treated maxillary premolar with confluent root canals ...
