Abstract
Background: A close anatomic relationship between the incisive canal and the roots of the central maxillary incisors should be kept in mind during dental-implant treatment in the anterior maxilla. The aim of the present study is to analyze incisive canal characteristics on computed tomography (CT) sections and to evaluate its relation to bone anterior to the canal with regard to dental implantation. Methods: A total of 933 partially edentulous and/or edentulous patients scheduled for implant insertion in four dental clinics enrolled in the present study. The following were measured and recorded from CT sections for analysis: 1) diameter and length of the incisive canal; 2) width and length of the bone anterior to the canal; 3) palatal bone width and length; and 4) root width and length of the central incisor. Results: Mean canal length was 10.86 ± 2.67 mm, and mean diameter was 2.59 ± 0.91 mm. Canal length was shortened in edentulous anterior maxilla compared to dentate maxilla. However, canal diameter did not show any difference between dentate and edentulous groups. Males had a longer and wider incisive canal than females. Canal shape was mostly cylindrical in 40.73% of images. No correlation was found with mean canal length and mean canal diameter according to age. Conclusions: Although variations exist in every patient, the findings from this study suggest that sex and dental status are important factors that can affect incisive canal characteristics and amount of bone anterior to the canal. Clinicians should perform careful planning using CT scans before performing dental implant surgeries in premaxillary region.

Canal shape was mostly cylindrical in 40.73% of images. No correlation was found with mean canal length and mean canal diameter according to age. Conclusions: Although variations exist in every patient, the findings from this study suggest that sex and dental status are important factors that can affect incisive canal characteristics and amount of bone anterior to the canal. Clinicians should perform careful planning using CT scans before performing dental implant surgeries in premaxillary region.</s0></fC01><fC02 i1="01" i2="X"><s0>002B10</s0></fC02><fC02 i1="02" i2="X"><s0>002B25C02</s0></fC02><fC03 i1="01" i2="X" l="FRE"><s0>Traitement</s0><s5>04</s5></fC03><fC03 i1="01" i2="X" l="ENG"><s0>Treatment</s0><s5>04</s5></fC03><fC03 i1="01" i2="X" l="SPA"><s0>Tratamiento</s0><s5>04</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Tomodensitométrie</s0><s5>05</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Computerized axial tomography</s0><s5>05</s5></fC03><fC03 i1="02" i2="X" l="SPA"><s0>Tomodensitometría</s0><s5>05</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Chirurgie</s0><s5>06</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Surgery</s0><s5>06</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Cirugía</s0><s5>06</s5></fC03><fC03 i1="04" i2="X" l="FRE"><s0>Evaluation</s0><s5>07</s5></fC03><fC03 i1="04" i2="X" l="ENG"><s0>Evaluation</s0><s5>07</s5></fC03><fC03 i1="04" i2="X" l="SPA"><s0>Evaluación</s0><s5>07</s5></fC03><fC03 i1="05" i2="X" l="FRE"><s0>Maxillaire</s0><s5>08</s5></fC03><fC03 i1="05" i2="X" l="ENG"><s0>Maxillary</s0><s5>08</s5></fC03><fC03 i1="05" i2="X" l="SPA"><s0>Maxilar</s0><s5>08</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Homme</s0><s5>09</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Human</s0><s5>09</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Hombre</s0><s5>09</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Incisive</s0><s5>13</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Incisor</s0><s5>13</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Incisivo</s0><s5>13</s5></fC03><fC03 i1="08" i2="X" l="FRE"><s0>Lambeau</s0><s5>14</s5></fC03><fC03 i1="08" i2="X" l="ENG"><s0>Flap (surgery)</s0><s5>14</s5></fC03><fC03 i1="08" i2="X" l="SPA"><s0>Colgajo</s0><s5>14</s5></fC03><fC03 i1="09" i2="X" l="FRE"><s0>Tomographie</s0><s5>15</s5></fC03><fC03 i1="09" i2="X" l="ENG"><s0>Tomography</s0><s5>15</s5></fC03><fC03 i1="09" i2="X" l="SPA"><s0>Tomografía</s0><s5>15</s5></fC03><fC03 i1="10" i2="X" l="FRE"><s0>Dentisterie</s0><s5>30</s5></fC03><fC03 i1="10" i2="X" l="ENG"><s0>Dentistry</s0><s5>30</s5></fC03><fC03 i1="10" i2="X" l="SPA"><s0>Odontología</s0><s5>30</s5></fC03><fC03 i1="11" i2="X" l="FRE"><s0>Implant dentaire</s0><s4>CD</s4><s5>96</s5></fC03><fC03 i1="11" i2="X" l="ENG"><s0>Dental implant</s0><s4>CD</s4><s5>96</s5></fC03><fC07 i1="01" i2="X" l="FRE"><s0>Imagerie médicale</s0><s5>37</s5></fC07><fC07 i1="01" i2="X" l="ENG"><s0>Medical imagery</s0><s5>37</s5></fC07><fC07 i1="01" i2="X" l="SPA"><s0>Imaginería médica</s0><s5>37</s5></fC07><fC07 i1="02" i2="X" l="FRE"><s0>Radiodiagnostic</s0><s5>38</s5></fC07><fC07 i1="02" i2="X" l="ENG"><s0>Radiodiagnosis</s0><s5>38</s5></fC07><fC07 i1="02" i2="X" l="SPA"><s0>Radiodiagnóstico</s0><s5>38</s5></fC07><fN21><s1>122</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard><server><NO>PASCAL 12-0160711 INIST</NO><ET>Evaluation of Maxillary Incisive Canal Characteristics Related to Dental Implant Treatment With Computerized Tomography: A Clinical Multicenter Study</ET><AU>TÖZÜM (Tolga F.); GÜNCÜ (Güliz N.); YILDIRIM (Ya========gbreve;mur D.); GUNEY YILMAZ (Hasan); GALINDO-MORENO (Pablo); VELASCO-TORRES (Miguel); AL-HEZAIMI (Khalid); AL-SADHAN (Raed); KARABULUT (Erdem); WANG (Hom-Lay)</AU><AF>Department of Periodontology, Faculty of Dentistry, Hacettepe University/Ankara/Turquie (1 aut., 2 aut., 3 aut.); Department of Periodontology, Faculty of Dentistry, Near East University/Mersin/Turquie (4 aut., 6 aut.); Department of Oral Surgery and Implant Dentistry, University of Granada/Granada/Espagne (5 aut.); Division of Periodontics, College of Dentistry, King Saud University/Riyadh/Arabie Saoudite (7 aut., 10 aut.); Diagnostic Sciences Department, College of Dentistry, King Saud University./Etats-Unis (5 aut., 8 aut.); Department of Biostatistics, Faculty of Medicine, Hacettepe University/Etats-Unis (9 aut.); Department of Periodontics and Oral Medicine, School of Dentistry, University of Michigan/Ann Arbor, MI/Etats-Unis (10 aut.)</AF><DT>Publication en série; Niveau analytique</DT><SO>Journal of periodontology : (1970); ISSN 0022-3492; Etats-Unis; Da. 2012; Vol. 83; No. 3; Pp. 337-343; Bibl. 16 ref.</SO><LA>Anglais</LA><EA>Background: A close anatomic relationship between the incisive canal and the roots of the central maxillary incisors should be kept in mind during dental-implant treatment in the anterior maxilla. The aim of the present study is to analyze incisive canal characteristics on computed tomography (CT) sections and to evaluate its relation to bone anterior to the canal with regard to dental implantation. Methods: A total of 933 partially edentulous and/or edentulous patients scheduled for implant insertion in four dental clinics enrolled in the present study. The following were measured and recorded from CT sections for analysis: 1) diameter and length of the incisive canal; 2) width and length of the bone anterior to the canal; 3) palatal bone width and length; and 4) root width and length of the central incisor. Results: Mean canal length was 10.86 ± 2.67 mm, and mean diameter was 2.59 ± 0.91 mm. Canal length was shortened in edentulous anterior maxilla compared to dentate maxilla. However, canal diameter did not show any difference between dentate and edentulous groups. Males had a longer and wider incisive canal than females. Canal shape was mostly cylindrical in 40.73% of images. No correlation was found with mean canal length and mean canal diameter according to age. Conclusions: Although variations exist in every patient, the findings from this study suggest that sex and dental status are important factors that can affect incisive canal characteristics and amount of bone anterior to the canal. Clinicians should perform careful planning using CT scans before performing dental implant surgeries in premaxillary region.</EA><CC>002B10; 002B25C02</CC><FD>Traitement; Tomodensitométrie; Chirurgie; Evaluation; Maxillaire; Homme; Incisive; Lambeau; Tomographie; Dentisterie; Implant dentaire</FD><FG>Imagerie médicale; Radiodiagnostic</FG><ED>Treatment; Computerized axial tomography; Surgery; Evaluation; Maxillary; Human; Incisor; Flap (surgery); Tomography; Dentistry; Dental implant</ED><EG>Medical imagery; Radiodiagnosis</EG><SD>Tratamiento; Tomodensitometría; Cirugía; Evaluación; Maxilar; Hombre; Incisivo; Colgajo; Tomografía; Odontología</SD><LO>INIST-874.354000194648670100</LO><ID>12-0160711</ID></server></inist></record>Pour manipuler ce document sous Unix (Dilib)
