Abstract
Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of mandibular atrophy and genial spines enlargement. Case Description. A 76-year-old female patient was referred for the assessment due to the complaint of chronic trauma in the anterior region of the floor of the mouth, which had been present for 2 months. CBCT images showed severe resorption of alveolar ridge and genial spines enlargement (5.5 mm × 12 mm). Conclusion. Accurate imaging assessment with the aid of 3D reconstructions allows the elimination of image superimposition and, therefore, plays an important role in the depiction of anatomical and pathological conditions, such as genial spines enlargement.
Highlights
Cone beam computed tomography (CBCT) is a relatively new technology used for the three-dimensional (3D) imaging of the hard tissues of the maxillofacial region [1, 2]
This paper reports a case in which CBCT 3D imaging was used to show mandibular atrophy and abnormal size of the genial spines in a patient wearing a complete denture
Genial spines are normally quite small [5]; if the size is increased, they may lead to a chronic irritation by the poorly adapted prosthesis leading to an anatomic modification and, interfering with success of mandibular prosthesis [3]
Summary
Cone beam computed tomography (CBCT) is a relatively new technology used for the three-dimensional (3D) imaging of the hard tissues of the maxillofacial region [1, 2]. This technology, when compared to conventional computed tomography (CT), has many advantages, such as radiation dose reduction, higher spatial resolution, and rapid scan time [1]. Genial spines consist of a group of four bony extensions situated in the lingual aspect of the anterior region of the mandible, surrounding the lingual foramen [3]. The superior and inferior genial spines provide attachment for the genioglossus muscle and the geniohyoid muscle, respectively [4]
