“…Results from our present study revealed that sinus septa were observed in 55.2% of the 270 sinuses. The prevalence of sinus septa found by Güncü et al 13 was 16.1%, by Krennmair et al 18 was 16%, and by Kim et al 19 was 26.5% when CT was used to assess the sinuses. These results are not consistent with those of the present study.…”

Evaluation of the posterior superior alveolar artery and the maxillary sinus with CBCT Abstract: Assessment of the maxillary sinus anatomy before sinus augmentation is important for avoiding surgical complications, because of the close anatomical relationship between the posterior maxillary teeth and the maxillary sinus. The posterior superior alveolar artery (PSAA) is the branch of the maxillary artery that supplies the lateral sinus wall and overlying membrane. We evaluated the location of the PSAA and its relationship to the alveolar ridge and maxillary sinus using cone beam computed tomography (CBCT). The study group consisted of 135 CBCT scans (270 sinuses) obtained from the archive of the dentomaxillofacial radiology department at Yeditepe University Faculty of Dentistry, Istanbul, Turkey. The distance between the lower border of the artery and the alveolar crest, bone height from the sinus floor to the ridge crest, distance from the artery to the medial sinus wall, and the diameter and location of the artery were determined. The occurrence of septa and pathology were recorded from CBCT scans. The PSAA was observed in 89.3% of sinuses, and 71.1% of arteries were intraosseous with diameters mostly ≤ 1 mm (68.9%). The prevalence of sinus septa was 55.2%, and that of sinus pathology was 57.4%. The mean age was 43.07 ± 17.55 years. There was a statistically significant difference between the location of the artery and gender (p < 0.05). The prevalence of sinus membrane thickening was 57.4%. Detailed knowledge about the location of the PSAA and sinus morphology may be obtained with CBCT before maxillary sinus surgery.

Summary: Maxillary sinus septa and bony bridges were observed using dry skulls in childhood, classified based on Hellman's dental age, to clarify maxillary sinus septum formation.Eighty-eight maxillary sinuses of 44 dry skulls and a cone-beam computed tomography (CBCT) unit were used. The locations of the septum, defined as a pointed bony structure originating from the inferior wall, and bony bridge, defined as a bony structure between the maxillary sinus wall and dental germ, were antero-posteriorly recorded, and the superoinferior distance, distance from the bony palate, and angle to the median palatine suture were measured.The rate of septum presence in the maxillary sinus was high (41.7%) in IIIC, and the septa were located in the deciduous molars, premolars, and molars. Also, all bony bridges were related to the median maxillary sinus wall, and the rate of the maxillary sinus showing a bony bridge was high in IIA and IIIA.

“…Estas relaciones anatómicas pueden variar dependiendo del grado de neumatización del seno maxilar, si-tuación que se ve exacerbada al perder un diente, describiéndose neumatizaciones tanto hacia la pared anterolateral del seno como también hacia la tuberosidad del maxilar. De este modo la altura del proceso alveolar se ve alterada tanto por la reabsorción alveolar como también por la neumatización del seno maxilar (Gosau et al;Kim et al, 2006;Lee et al;Maestre-Ferrín et al, 2010;Raja).…”

INTRODUCCIÓNLa pérdida de piezas dentarias determina cambios morfológicos y funcionales importantes a nivel del sistema cráneo cervicomandibular. Estos cambios se pueden ver reflejados tanto a nivel oral como a nivel extraoral, siendo estos últimos dependientes de la ubicación de la pieza perdida. Los principales cambios morfológicos a nivel oral se establecen por la pérdida progresiva del proceso alveolar tanto en altura como en grosor (Gosau et al., 2009;Raja, 2009). El patrón de reabsorción del proceso alveolar varía si la pérdida de la pieza dentaria es superior o inferior, ya que el patrón reabsortivo maxilar se describe como centrípeto a diferencia del patrón reabsortivo mandibular que se describe como centrifugo.El arco dentario en el maxilar presenta relaciones anatómicas distintas dependiendo de la pieza dentaria, reconociéndose 4 grupos dentarios: a) en relación al piso de la cavidad nasal, siendo estos fundamentalmente el grupo incisivo. b) en relación al pilar canino, vale decir por lateral a la pared lateral de la cavidad nasal y por medial a la pared medial y anterior del seno maxilar, se describe en esta región al diente canino; c) en relación al piso del seno maxilar, a este grupo pertenecen los premolares y los primeros y segundos molares; d) en relación a la tuberosidad del maxilar, encontrándose en este grupo fundamentalmente al tercer molar. Estas relaciones anatómicas pueden variar dependiendo del grado de neumatización del seno maxilar, si- RESUMEN: La pérdida de dientes superiores causa reabsorción del proceso alveolar y la neumatización del seno maxilar. La implantología oral ha permitido solucionar la perdida de dientes, sin embargo, cuando existe neumatización del seno maxilar, la disponibilidad ósea se ve disminuida, dificultando el procedimiento implantologico. Para remediar esta situación se efectúa la técnica quirúr-gica de levantamiento del piso del seno maxilar, la que puede tener complicaciones por la morfología interna del seno, específicamente por la presencia de septos intrasinusales. El objetivo de este estudio es verificar la presencia y distribución de los septos intrasinusales, debido a su importancia en técnicas quirúrgicas realizadas en implantología oral. Se realizó un estudio descriptivo, basado en el análisis visual de huesos maxilares aislados. De 65 huesos se seleccionaron 51(42 dentados y 9 edéntulos) que cumplían con determinados criterios de inclusión. La segunda parte del estudio consistió en dividir topográficamente el piso del seno en tres regiones: anterior a la cresta cigomato alveolar, en relación a ella, y posterior a la cresta. La observación de los septos fue realizado por un único examinador, asistido por un dispositivo USB, con 4 leds de alta luminiscencia. De los 51 maxilares analizados se obtuvo: 74,5%, presentaron al menos un septo intrasinusal, 25,4%, no presentaron septos visibles. Los maxilares que presentaron un único tabique correspondieron al 33,3% de la muestra, el 19,6 % de la muestra presento sólo dos tabiques, el 15,7% presentó tres tabiqu...
