“…Many anatomical structures, such as the incisive nerve [ 35 , 39 , 40 ], the alveolar inferior nerve [ 41 ], and its anterior loop [ 40 , 42 ], are more easily visualized on CBCT images [ 14 ] in contrast to 2-D images. Since measurement inaccuracies in CBCT scans can exceed 1 mm, a safety margin of 2 mm from vital structures should be utilized in implant planning [ 21 , 37 ].…”

Indications for 3-D diagnostics and navigation in dental implantology with the focus on radiation exposure: a systematic review

Background Dental implants are a common restorative method used to replace missing teeth. Implant placement techniques guided by three-dimensional imaging and navigation are becoming more widely available. Objective The present review focused on the following questions: 1. What are the advantages and disadvantages of 2-D versus 3-D imaging in dental implantology? 2. What are the advantages and disadvantages of freehand implant placement in comparison with navigation-guided implant placement? Methods A systematic review was performed, based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. The following libraries were searched for relevant literature: PubMed, Embase, Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften (AWMF) Online, and the Cochrane Library. The risk of bias was assessed using the Scottish Intercollegiate Guidelines Network (SiGN) checklist. A total of 70 studies were included after screening, and the evidence from these was gathered for review. Results Three-dimensional imaging is advantageous in terms of image quality, and it provides a distortion-free evaluation of the implant site. However, it is also associated with higher costs and increased radiation exposure. Dynamic and static navigation are equal in accuracy and are both more accurate compared with the freehand method. No benefit in terms of implant survival could be demonstrated within the first 5 years for any specific method. Discussion A panoramic X-ray with a reference body often provides sufficient imaging and is the primary method for two-dimensional imaging. Cone beam computed tomography with low-dose protocol settings should be used if three-dimensional imaging is needed. Navigational support should be considered in the event of especially complex cases. Conclusion The guidance technique used for implant placement should be decided on an individual basis. With the increasing availability of three-dimensional imaging, there should also be an increase in awareness of radiation exposure.

“…Although the genial spinal canal is seldom described in anatomy textbooks, it is doubtless present in almost 100% of cases as confirmed by different investigations (Liang et al, 2006;Birkenfeld et al, 2015;Ferreira Barbosa et al, 2019;Gilis et al, 2019). In the literature, there is some confusion about the nomenclature of this structure in the mandible (He et al, 2017), possibly because there is no defined term for it in the official terminologia anatomica (FIPAT, 2011) In some publications, the term "incisive canal" is used (Serman, 1989;Jacobs et al, 2002;Mraiwa et al, 2003;Raitz et al, 2014;Pereira-Maciel et al, 2015;Ramesh et al, 2015;Gomes et al, 2018;Ferreira Barbosa et al, 2019;Gilis et al, 2019).…”

“…At the beginning of implant dentistry, Brånemark placed implants in the midline of the mandible, as some of his fixed dental prostheses were retained by five implants instead of four with one in the midline of the mandible (Adell et al, 1970;Brånemark et al, 1977). To the best of the present authors' knowledge, he never reported any sensory irritation within his patient cohort, although it is known from the literature that a genial spinal canal is present in almost 93% of human mandibles (Ferreira Barbosa et al, 2019) and this canal is hit during implant placement in the anterior mandible in almost 90% of cases (Birkenfeld et al, 2015). Walton investigated the sensory aspect after implant placement in the anterior mandible in 75 subjects (Walton, 2000).…”

Three‐Dimensional Reconstruction of the Genial Spinal Canal

et al. 2019

The aim of this anatomical study was to investigate the genial spinal canal histologically and to reconstruct it three‐dimensionally to improve understanding of its anatomy and to reveal any differences between dentate and edentulous specimens. Two tissue blocks from the mandible between the left and right second incisors, one dentate and one edentulous, were fixed in 4.5% formaldehyde, decalcified and embedded in paraffin. Serial histological sections were prepared, stained with Azan and examined microscopically. Additionally, three‐dimensional models of the blocks were reconstructed using microphotographs of the sections. The genial spinal canal in the dentate specimen contained a neurovascular bundle, which branched into a nerve innervating the incisor and a neurovascular bundle, whereas that in the edentulous specimen contained some nerves for vestibular gingival innervation and a vascular bundle. The results suggest differences in the genial spinal canal between dentate and edentulous mandibles. Further research is needed to confirm this finding. Clin.

“…La presencia del canal incisivo mandibular ha sido observado en un 100 % en disecciones cadavéricas (Xu et al, 2015) siendo, actualmente, la CBCT la mejor manera de evaluar la región maxilar-mandibular (Gomes et al, 2018), ya que permite la reconstrucción tridimensional de imágenes de alta resolución de toda la mandíbula, informándose excelentes imágenes de la mandíbula y el canal mandibular, junto a una alta precisión de las mediciones lineales, una baja dosis de radiación y un menor costo en comparación con la tomografía computarizada tradicional (Kong et al). Ferreira Barbosa et al (2019) en su revisión sistemática describe la identificación del canal incisivo mandibular en los estudios que va de un 71 % al 100 % de las muestras analizadas mediante CBCT, identificándose el MIC en el 89,6 % de los estudios analizados.…”

RESUMEN:El canal incisivo mandibular (MIC) es un canal neural que contiene una de las ramas inferiores del nervio alveolar inferior, llamado nervio incisivo mandibular, que puede resultar dañado durante intervenciones quirúrgicas y causar complicaciones postoperatorias. Estudio descriptivo de corte transversal. Se identificó el MIC en la imagen transversal del canino en 83 hemiarcadas. Se registró edad, sexo, hemiarcada, longitudes desde reborde alveolar vestibular de canino a MIC, cortical lingual y vestibular de canino a MIC, base mandibular de canino a MIC y ubicación del MIC (tercio lingual, medio, vestibular). Medidas se registraron en milímetros. Se aplicó test T-student para muestras independientes para variables de longitud y Chi-cuadrado para ubicación espacial del MIC, en relación con grupo etario y sexo. Se evaluó el MIC en todas las muestras (100 %). El MIC fue encontrado mayormente en el tercio medio mandibular (p <0,05). La media desde el MIC a la cortical lingual es de 5,25 mm ± 1,42 mm (derecho) y 5,24 mm ± 1,18 mm (izquierdo). La media desde el MIC a la cortical vestibular fue de 4,42 mm ± 1,29 mm (derecho) y 4,53 mm ± 1,24mm (izquierdo). La media entre centro del canal y reborde alveolar vestibular fue 18,89 mm ± 2,68mm (derecho) y 18,20 mm ± 3,06 mm (izquierdo), media desde centro del MIC al margen basal fue de 9,77 mm ± 1,93 (derecho) y 10,12 mm ± 1,92 mm (izquierdo). Se encontró mayor distribución del MIC en el tercio medio mandibular. Se identificó el MIC en el 100 % de las muestras a través de CBCT por lo que su uso como examen complementario debe ser considerado al planificar cirugías en el sector anterior mandibular.
