Condylar guidance angles obtained from panoramic radiographic images: An evaluation of their reproducibility

Abstract

Background. The method of using panoramic radiographic images to obtain numerical data on the condylar guidance angle has been described in the literature.

Treatment of high fracture of the neck of the mandibular condylar process by rigid fixation performed by lag screws: Finite element analysis

“…2 However, open internal rigid fixation (ORIF) treatment allows restoration of vertical ramus height, i.e. prevention of occlusal disorders, anatomical position of the bone fragments and the disc, physiological function of the disk and condyle 3 as well as that of the lateral pterygoid muscle that allows immediate functional movement of the jaw, avoids ankylosis of the temporomandibular joint induced by trauma and yields a pain-free result for the patient. 4,5 Several techniques have been proposed to reduce and fix the fractures, such as standard bone screws and plates and a long lag screw, by promising biomechanical fixation.…”

An evaluation of the relationship between the range of mandibular opening and the condyle positions in functional panoramic radiographs

“…One of the basic plain examinations of the TMJ is an OPG, commonly used and widely available in dental treatment. 8 Admittedly, the image obtained is a flat reflection of the curved surface of the maxilla and a composite image of the tissues located in the X-ray's path; however, it provides a sufficiently accurate visualisation of the bone structures around the TMJ. 8,9 A functional OPG is a modification of an OPG examination and is performed in the following positions: habitual occlusion (maximum contact between the teeth of opposing arches) and maximum opening (maximum opening of the mandible in relation to the maxilla), each separately for the right and left sides (a separate image for each TMJ).…”
