“…Large individual variations in the anatomical morphology of the IC exist [54]. Arnaut et al [60] reported that different shapes of the sagittal cross-section of the IC, such as funnel, cylindrical, and hourglass shapes, are associated with the distance to the MCI, and they concluded that different shapes could be a regression limiting factor for the MCI.…”

The position of the maxillary central incisors (MCIs) is an important factor in treatment planning since it is related to esthetics and physiological function. This study aimed to evaluate maxillofacial morphology related to the proximity of the MCI to the incisive canal (IC) using cone-beam computed tomography (CBCT). In 157 patients, the distance between the MCI and IC was measured using CBCT images, and the maxillofacial morphology was measured using cephalograms. The relationship between age, sex, and cephalometric analysis was subsequently investigated using stepwise multiple regression analysis, with the distance between the MCI root apex and IC as the objective variable, and age, sex, and cephalometric variables as explanatory variables. The results demonstrated significant associations between the distance separating point A and the pterygomaxillary fissure projected on the palatal plane (B = 0.092, p < 0.01), the maxillary central incisal edge to the Frankfort horizontal plane (B = −0.058, p < 0.01), and the mandibular plane (B = −0.036, p = 0.031). Age and sex showed no association with the distance between the IC and MCI. Particular attention should be paid to the proximity of the tooth root to the IC in patients with short anteroposterior diameters of the maxilla and an anterior labial tilt of the dolichofacial type.

“…On the contrary, the distance between the root and the wall of IC increases with the increase in height. At the root tip, the distance from the incisive canal is the furthest, and the diameter of the incisive canal is smaller than the distance between the roots of bilateral upper central incisors at this level 15,17 . Therefore, the most dangerous place is the mesial palatal side of the root 1/3, not the apex.…”

The position of the maxillary central incisor (MCI) directly affects the appearance of the patient's profile. For patients with bimaxillary protrusion or maxillary protrusion, orthodontic treatment often adopts a large number of retractions of the maxillary anterior teeth to improve the profile. However, the retraction of MCI is limited, and the maximum retraction depends on the distance between the root of MCI and the incisor canal(IC). This distance is not a constant value and is affected by many factors. This article reviews the influencing factors of the maximum retraction of MCI and its clinical significance in orthodontic treatment.

“…Moreover, another studies using CBCT in anterior maxilla analyze that detection of various anatomic structures, may be useful in the prevention of complications during surgical intervention, as implant placement (49,57). Still, the morphological observed algorithms of the anterior maxilla may offer detailed information that can be used for planning orthodontic teeth movement (58). The justification of CBCT for preoperative implant plan is based on accurate information about vital structures, height, and width of bone, bone density, and alveoli profile (51,59,60).…”

The interradicular septum describes area in the root furcation that separate alveoli of multi-rooted teeth. The shape and dimension depend of the topography of the extraction socket, the geometry of residual root and anatomy of molars alveoli. The clinical implications of this anatomic structure may be used in oral surgery resection procedures, periodontology and implantology. There is an opinion from the surgical and prosthodontic side that center of interradicular septum may be adequate place for immediate implantation. The aim of this study was to investigate morphological characteristics and clinical implications of upper molars interradicular septum. The studies showed that interradicular septum is important for success of resection surgery procedures: hemi-section, bisection and root amputation. It’s reported that furcation involvement in periodontal disease is clinical sign for severe bone loss. By reviewing the available literature for immediate implantation, it’s reported the clinical implications for diagnostical plan (pre-intervention), presurgical (pre-instrumentation) and intraoperative evaluation of interradicular septum for immediate implantation. The cone beam computed tomography analyze study presented mean values of septum height and wide for hypothetical plan of immediate implant placement. The presurgical studies evaluate how to assure preservation of septum and safe implant position in center of septum. The research showed varies therapy modalities that can be used, and how to choose right therapy according the socket type and initial septum width classification. According to observation of studies results, other researches should be considered for CBCT anatomical structure analyze and measures of interradicular septum for immediate implantation planning.
