“…Agthong et al [1] and Neiva et al [20] found the MF at a distance 15 mm and 12 mm from the IBM, while the classic anatomical textbooks describe the MF position closer to the IBM, concerning the skulls of juveniles [31]. Our study concluded that the MF is located at an average distance 15.2 mm and 12.6 mm from the IBM in dentate and edentulous mandibles, respectively.…”

Background: The knowledge of the exact location of the mental foramen (MF) in dentate and edentulous mandibles is clinically important when constructing complete dentures, performing anaesthetic block of the lower-anterior teeth area and intervening in the MF nearby area. In edentulous mandibles, the bone resorption after teeth loss makes the mental nerve (MN) prone to damage due to the extreme location of the MF very close to the alveolar crest (AC). Chronic compression on the MN may result in pain in the area of MN distribution (ipsilateral face and cheek area) and numbness at the lower lip. The purpose of the current study is to evaluate the exact position of the MF, calculating the distances MF-superior border of the AC and MF-inferior border of the mandible (IBM) in (p = 0.39 and p = 0.45). Conclusions:The MF is an important landmark and its location needs to be considered prior to dental implants placement in order to avoid the MN injury and related complications. The position of MF is altered in edentulous mandibles compared with the dentate ones. The MF is a symmetric structure in Greeks. (Folia Morphol 2017; 76, 4: 709-714)

“…Few studies have used skulls or cadavers to study the thickness of the buccofacial wall of the maxillary sinus. Neiva et al, 16 who did so using skulls, measured the thickness of the buccofacial wall of the maxillary sinus using a Boley gauge caliper in four locations (mesial, distal, apical and coronal) and reported that the mean thickness of the lateral wall of the maxillary sinus was 0.91 ± 0.43 mm (range 0.5-2.0 mm). In a study of 74 Korean hemiface cadavers, Yang et al 13 removed the lateral sinus wall to measure the buccofacial wall at various marked points using a bone depth gauge.…”

“…In general, this is higher than the values that have been reported for Caucasians and Koreans. 14,16,19 Only 2 other studies reported observing a thickness of more than 2 mm. 12, 18 Li et al 12 reported a thickness of 2.23 mm at the second premolar and a thickness of 2.19 mm at the first molar region 5 mm from the floor of the sinus in Han Chinese.…”

“…However, the vulnerability of the Schneiderian membrane to perforation during this procedure means that it must be managed cautiously while considering the thickness of the buccofacial wall of the maxillary sinus. 11 A few studies have described the topography and thickness of the buccofacial sinus wall, 12,13,14,15,16,17,18,19 but none of these have involved Southeast Asian populations.…”

The objective of this study was to measure the topographic thickness of the lateral wall of the maxillary sinus in selected Asian populations. Measurements were made on the lateral walls of maxillary sinuses recorded using CBCT in a convenient sample of patients attending an Asian teaching hospital. The points of measurement were the intersections between the axes along the apices of the canine, first premolar, and second premolar and along the mesiobuccal and distobuccal apices of the first and second molars and horizontal planes 10 mm, 20 mm, 30 mm and 40 mm beneath the orbital floor. The CBCT images of 109 patients were reviewed. The mean age of the patients was 33.0 (SD 14.8) years. Almost three quarters (71.8%) of the patients were male. The mean bone thickness decreased beginning at the 10-mm level and continuing to 40 mm below the orbital floor. Few canine regions showed encroachment of the maxillary sinus. The thickness of the buccal wall gradually increased from the canine region (where sinus encroachment of the canine region was present) to the first molar region, after which it decreased to the thickness observed at the canine region. The buccal wall of the maxillary sinus became thicker anteroposteriorly, except in the region of the second molar, and thinner superoinferiorly. These changes will affect the approach used to osteotomize the lateral sinus wall for oral surgery and for the sinus lift procedure.

Morphometric Analysis of Implant‐Related Anatomy in Caucasian Skulls

Abstract: Implant-related anatomy must be carefully evaluated before treatment due to considerable variations among individuals, in order to prevent injury to surrounding anatomical structures and possible damage.
