Por qué importa

Este estudio, publicado en The International Journal of Esthetic Dentistry, evalúa mediante CBCT las dimensiones de los incisivos mandibulares y su hueso alveolar circundante para determinar la viabilidad de la colocación inmediata de implantes en esta zona. Se analizaron 404 incisivos de 101 pacientes, registrando diversas medidas óseas y dentales, como el ancho del hueso alveolar y la angulación entre el eje dental y óseo. Los hallazgos sugieren que, aunque la colocación inmediata de implantes puede ser predecible, es crucial una cuidadosa consideración de los requisitos anatómicos específicos del área anterior mandibular, especialmente en incisivos centrales donde el ancho óseo puede ser un factor limitante. Los resultados aportan datos cuantitativos que pueden influir en la planificación clínica y la toma de decisiones para mejorar el éxito y la predictibilidad de los tratamientos implantológicos en esta región.

Abstract original

Background: Immediate implant placement (IIP) has shown predictable outcomes when specific requirements are met. The aim of the present study was to radiographically evaluate the dimensions of mandibular incisors and the alveolar bone to further determine the feasibility of IIP in this area. Materials and methods: A total of 404 intact mandibular incisor CBCT images from 101 patients (42 males, 59 females; mean age 49 ± 16.84 years) were analyzed. The mesiodistal tooth width and the distance between the incisal edge (IE), cementoenamel junction (CEJ), facial bone crest (BC), root apex (RA), and fenestration point (F) were registered, together with the alveolar bone width at 1 and 3 mm below BC. Finally, the angular discrepancy between the dental and the alveolar bone long axis (BLA) was recorded as the tooth torque (TT). Results: The CEJ to BC distance was 3.23 ± 1.67 mm. The RA to F mean distance was 15.02 ± 3.97 mm. The mean alveolar bone buccolingual widths at 1 and 3 mm below the facial BC were 7.12 ± 0.82 and 6.32 ± 0.71 mm in the lateral and central incisors, respectively (P 0.001). The buccolingual width was less than 6 mm in more than 33% of the central incisors, but only in 3% of the lateral incisors, displaying increased alveolar width. The average was 165.66 ± 7.47 degrees. Conclusions: The results presented in this study point toward the need for careful consideration of the requirements for anterior mandibular IIP for success and predictability purposes.
