‘The risk of MRONJ after dental extraction was significantly higher in patients treated with ARD (antiresorptive drugs) for oncological reasons (3.2%) than in those treated with ARD for OP (osteoporosis) (0.15%) (p < 0.0001). Dental extraction performed with adjusted extraction protocols decreased MRONJ development significantly.
Usually people affected by TMD are between 20 and 40 years of age, [3] and it is more common in females than males. [10] TMD is the second most frequent cause of orofacial pain after dental pain (i.e. toothache). [11]
Pain, inflammation of the surrounding soft tissue, secondary infection or drainage may or may not be present. The development of lesions is most frequent after invasive dental procedures, such as extractions, and is also known to occur spontaneously. There may be no symptoms for weeks or months, until lesions with exposed bone appear. [5]
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
Temporomandibular joint pain is generally due to one of four reasons. Myofascial pain dysfunction syndrome, primarily involving the muscles of mastication. This is the most common cause. Internal derangements, an abnormal relationship of the disc to any of the other components of the joint. Disc displacement is an example of internal derangement.
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
The mandible in contrast has a relatively poor blood supply, which deteriorates with increasing age. The cortical plates are thick and there is a medullary cavity. The sites of the mandible most commonly affected by OM are (decreasing order of frequency) the body, the symphysis, the angle, the ramus and finally the condyle.
In addition, secondary alveoloplasty sometimes occurs after the initial procedure to eliminate any gross bone irregularities. [ 18 ] A full thickness flap is usually elevated to a point apical to the desired area to be contoured, and according to the amount of bone needed to be removed, a bone file, or a bone rongeur , or a burr under copious ...
