Abstract
Anatomical variations of lingual foramen and it’ s bony canals with cone beam computerised tomography in south indian population – a cross sectional study
Highlights
The success of mandibular bone surgeries, such as implant placements, orthognathic surgeries depends on the various imaging modalities to determine the parameters of implant placement by revealing the structure of the mandible, alveolar bone shape, and volume
The lingual foramina region was in the Cone-beam computed tomography (CBCT) scans
From the 100 mandibles investigated, all patients had at least one lingual foramen, 58% had single lingual foramen, 42% had two lingual foramen and accessory canals were observed in 40% of the mandibles analyzed
Summary
The success of mandibular bone surgeries, such as implant placements, orthognathic surgeries depends on the various imaging modalities to determine the parameters of implant placement by revealing the structure of the mandible, alveolar bone shape, and volume. The conventional radiographs appear only in two dimensions, and the extent of magnification (10% to 30%) depends on the patient anatomy as parts of the mandible can obscure key elements in the image. Multi-planar slices of CBCT, which has fixed magnification, is clinically useful in determining implant parameters and preventing damage to vulnerable structures, such as the inferior alveolar neural tubes and maxillary antrum [2]. The mental spine is in the medial region of the lingual surface of the mandible and is surrounded by foramina connected by intraosseous canals. The sublingual and submental arteries are located in the floor of the mouth and enter the mandible through these foramina, sending branches to the mylohyoid muscle, peripheral muscles, mucous membrane, and gingiva [3]
