“…34 Stylomandibular ligament and sphenomandibular ligament attach to the mandible bone. 35 Also, the disk articulates with the mandibular fossa of the temporal bone above and the condyle of the mandible below. 36 So, the movement pattern of mandible bone determines the amount of von Mises stresses (or the protective efficiency of the mentioned mouthguards) applied to these tissues during the impact loading.…”

“…Additionally, in the human facial skeleton, the mandible bone, which is considered the only movable orofacial tissue 34 is separated from maxillary bone and upper teeth. Whereas stylomandibular and sphenomandibular ligaments attach to the mandible bone 35 and it holds the lower teeth in place, 49 also the disk articulates with the condyle of the mandible bone. 36 So, regarding the loading direction, the protective efficiency of a mouthguard for maxillary bone and upper teeth is related to its material and geometrical characteristics and compatibility with upper and lower teeth.…”

This paper aims to numerically investigate the protective efficiency of multilayered and boil-and-bite mouthguards on orofacial hard and soft tissues subjected to impact loadings. To the best of our knowledge, this is the first attempt which studies the protective efficacy of mouthguards on orofacial injuries including both hard and soft tissues such as articular disks, stylomandibular and sphenomandibular ligaments, that are commonly neglected in clinical and numerical studies. To address this issue, a finite element based numerical framework has been proposed using the Abaqus finite element software. This study considers three different situations of the craniofacial structure, without any mouthguard, with the customized multilayered mouthguard and with a boil-and-bite mouthguard. The protective effectiveness of mouthguards is numerically evaluated based on pressure and displacement distributions on the orofacial hard and soft tissues under two different actual impact loadings. In all cases the results revealed that the customized multilayered mouthguard can more effectively reduce the stress concentration on orofacial hard and soft tissues which is the key factor to evaluate the protective efficiency of different types of mouthguard. As an example, a comparison between the protective efficiency of multilayered and boil-and-bite mouthguards reveals that under uppercut punch impact loading, the multilayered mouthguard performs 18.45% and 21.32% more effective respectively for upper and lower teeth and stylomandibular ligament. Furthermore, the simulation results for stylomandibular ligament and articular disk enable us to conclude that wearing a customized multilayered mouthguard cannot be replaced by a boil-and-bite mouthguard, since it causes more harm in comparison to the unprotected case.

“…The bucco-lingual mandibular bone width is known to increase from the premolar area to the molar area 8. Chinoa et al,9 reported that bone width, buccal to mandibular premolars and molars, at 3 mm coronal to the root apex, and they discovered that the width of the buccal bone increases from the first premolar to the second premolar.…”

Objectives: To evaluate the horizontal and vertical location of the mental foramen (MF), as well as the relationship of lower premolars to buccal and lingual cortical plates using cone beam computed tomography (CBCT). Methods: Retrospective cross-sectional study conducted using CBCT scans that were obtained between early 2014 and late 2016 from King Saud University Dental hospital database in Riyadh, Kingdom of Saudi Arabia; 94 patients (53 males and 41 females) were included. Three examiners independently performed one-sided measurements for each patient. Data analyzed statistically and a p <0.05 was considered significant. Results: The mean distances from the outer boundary of the buccal cortex to the first and second premolars (R1) were 1.55 mm and 1.98 mm. The mean distances from the outer boundary of the lingual cortical plate to the first and second premolars (R2) were 4.06 mm and 4.73 mm. The respective mean total bone thicknesses, including the roots of the first and second premolars (R3), were 9.32 mm and 10.08 mm. The mean distance between the MF and the mandibular second premolar apex was 3.13 mm. Conclusion: Mandibular premolars are in close proximity to MF especially mandibular second premolar. Presurgical assessment is essential when surgical treatment is planned at this area.
