“…Hence, if the width is not assessed erstwhile by CBCT imaging then it can lead to the perforation of the lingual cortical plate. 15 Another important anatomical landmark to be acknowledged is the presence of lingual foramen and canals. According to a study by Romanos GE et al 2012, panoramic radiograph can detect only 2.7% of lingual foramen.…”

Recently, Dental implants have taken the dental rehabilitation to another level. Dental implants are highly preferred over other rehabilitation techniques, as they have a more conservative approach with minimal damage to other adjacent structures. The aim of the study was to evaluate the prevalence of anatomical variations in maxilla and mandible on CBCT images of patients referred for dental implants. In our study, a total of 102 CBCT images comprising of 60 males & and 42 females with mean age of 50 years & 45 years were analysed. We found that in approximately 50% of the cases, the anterior loop of mental nerve was seen and lingual foramen was identified in the anterior part of the mandible in about 20% cases. Two-dimensional radiographs have been used for a long time as the only diagnostic tool in implant dentistry. However, radiographs may seem to be adequate for patients with wide residual ridges but CBCT effectively brings together prosthetic and surgical considerations which are important for beauty, restoration and prosthetic indices.

“…The main blood supply comes from a unilateral ascending mental artery, a branch of the submental artery that emerges from the submental triangle of the neck. It is possible that the sublingual artery of the lingual artery that anastomoses with the submental artery through the mylohyoid muscle can support blood flow to the chin in cases where the submental artery is occluded . The superior labial artery does not provide any branches to the chin.…”

“…The ascending mental artery is the terminal branch of the submental artery. The submental artery can send a branch into the floor of mouth through the mylohyoid muscle thus becoming the sublingual artery . This intimate relationship between the sublingual artery and the submental artery may increase the risk of lingual infarction during chin augmentation.…”

Summary Background Tongue and mouth floor infarction following filler injections for chin augmentation is a rare complication that has the increase in incidence been reported. Objective This study investigated the arterial anastomosis between the submental and sublingual arteries that can lead to the emboli and subsequent tongue infarction during chin augmentation. Methods Forty‐two formaldehyde‐embalmed cadavers and four soft‐embalmed cadavers were dissected to verify the incidence and source of the ascending mental artery. Ultrasonographic study of the artery was performed in 10 healthy volunteers. Attention was paid to discriminate whether the ascending mental artery arose from the submental artery or the sublingual artery using the arch of the mylohyoid muscle as the discriminating landmark. Results Incidence of ascending mental artery from the sublingual artery was 7.1% in the studied population. All ascending mental arteries were 0.7 ± 0.2 mm in diameter at the mental protuberance and were branches of the submental artery that arose from the facial artery, except for two arteries that arose from the sublingual artery. Ultrasonographic study revealed that one left and one right sublingual artery from the lingual arteries penetrated the mylohyoid muscle near the midline to become the ascending mental artery in two volunteers. The ascending mental artery from the other side continued from the submental artery. Conclusion Findings from the cadaveric dissections and ultrasonographic study revealed that the ascending mental artery may be a branch that continues from the lingual artery, or communicates with the sublingual artery through the mouth floor.

“…A minimum bone thickness of 6 mm would be required for successful placement of a standard-sized ±4-mm-diameter implant. 2 In the present study Mandibular Body Thickness (MBT) was studied in 110 dry mandibles to evaluate the ideal length of dental implants used during the corrective procedures on the mandibular alveolar process. All the mandibles in our study had adequate bone thickness needed for implant placement without traumatizing the sublingual artery.…”

There are several methods of reconstruction for lower human jaw, but the most common and safest is using plates and screws. The size of the lower jaw bone varies from person to person, therefore plates and screws are available in different sizes. 1 A critical buccal bone thickness of 2 mm is recommended to prevent vertical resorption. A minimum bone thickness of 6 mm would be required for successful placement of a standard-sized ±4-mm-diameter implant. 2 In the present study Mandibular Body Thickness (MBT) was studied in 110 dry mandibles to evaluate the ideal length of dental implants used during the corrective procedures on the mandibular alveolar process. All the mandibles in our study had adequate bone thickness needed for implant placement without traumatizing the sublingual artery.
