Maxillary Mandibulal Disease

950 Words4 Pages

Occlusion is the relationship between the opposing teeth, when the maxillary mandibular dental arches approaches each other as in chewing or at rest. If this occlusal relationship is not well balanced it can cause pain, tenderness or mobility of the affected teeth, dysfunctions of the masticatory muscles1 and even TMJ problems.2 In spite of the number of studies done over the years, the relationship between occlusion and periodontal disease still remains an area of considerable interest and controversy. The present clinical update try to review the signs and symptoms of trauma from occlusion, and the orthodontic aspects based on previous research works done in this field.: it refers to an occlusion which produces forces that can cause …show more content…

Clinical Features And Management
Review of literature shows that clinical features of trauma from occlusion include 4,8,9 progressive mobility of tooth, pain on chewing or percussion, positive fremitus test, occlusal prematurities/ discrepancies, wear facets, migration of tooth, chipped or fractured tooth (teeth), thermal sensitivity etc. There are other signs also which can be assessed radiographically. Radiographic signs include presence of widened perodontal ligament space, thickening of the lamina dura, bone loss (furcations) and root resorption , increase in bone in density or apical bone sclerosis .
Management of trauma from occlusion is done by removal of the excessive occlusal forces and attaining optimum functional occlusal relationships comfortable to the teeth and periodontium by methods such as occlusal adjustment, dental restorations, removal of selected teeth, occlusal reconstruction, management of parafunctional habits, stabilization of mobile teeth with removable or fixed appliances, orthodontic tooth movements and orthognathic …show more content…

A study done by Burgett 12found that patients in whom occlusal adjustment was done as a part of periodontal treatment showed an improvement in attachment level than those in whom occlusal adjustment was not done, though it was only statistically relevant. A pair of studies done in humans, found that teeth with occlusal discrepancies in the beginning had significantly greater initial probing depths, greater mobility and a worse prognosis than teeth without occlusal discrepancies to begin with13. It was also found that correction of occlusal discrepancies significantly reduced the progression of periodontal disease and also helps to optimize the treatment outcome. However there are studies reporting against the role of occlusal discrepancies in increased rate of periodontal destruction 14,15,16. Occlusal adjustment by selective grinding is indicated to eliminate premature contacts or occlusal interferences and it helps in equal distribution of all forces on the teeth and also establishes a harmonious relationship among the components of the stomatognathic system. (17-24). Though occlusal adjustment is

Chronic periodontitis Chronic Periodontitis is an inflammatory disease of the supporting tissues of the teeth caused by specific microorganisms or groups of specific microorganisms, leading to progressive destruction of the attachment apparatus of the teeth including periodontal ligament, cementum and alveolar bone with periodontal pocket formation, and recession of the gingival tissue(1) . The clinical feature that characterizes periodontitis from gingivitis is the presence of clinically apparent attachment loss. This loss mainly is associated with changes in the density and height of subjacent alveolar bone (1). Severe generalized periodontitis affects 5–15% of any population worldwide and is a major cause of teeth loss after dental caries (2). Chronic Periodontitis also known as adult periodontitis or chronic adult

Pain and pain on pressing were elevated, as were limited jaw movement and the bite feeling off. No clicking and popping were found during the clinical exam, suggesting that jaw functioning was not impaired, and this was confirmed by the TMJ Scale. The Non-TMJ scale was also elevated, reflecting the tension headaches. X-rays found no evidence of bony abnormalities. The patient reported significant emotional problems, and borderline stress, probably reflecting the result of eight months of searching for a solution for her pain problems.

INTRODUCTION Maxillofacial injuries have remained serious clinical problems because of the specificity of this anatomical region.1 Mandible in its vulnerable position and anatomic configuration is one of the most frequent facial bones to be involved in traumatic injuries with resultant fracture even though, it is considered the strongest and most rigid bone in the facial skeleton2 Weakest region of the mandible to fracture is the angle. Approximately 50% of fractures of the mandible involve areas with teeth and are the most important factor in determining where the fracture occurs.3 The presence of third molar is associated with 2-3 fold increased risk of angle fractures compared with the absence of third molar, and are most likely to occur in teens and twenties. This is of clinical interest because this age is most likely to have unerupted third molar.4,5 Mandibular angle fractures follow a pattern common to many injuries and this depends on multiple factors including direction, amount of force, presence of soft tissue bulk, and biomechanical characteristics of the mandible such as bone density,

Worldwide, malocclusion is becoming more and more common. It is estimated that 40-80% of the overall population is effected by malocclusion (5). Malocclusion occurs when teeth are misaligned, and impairs the functions of the craniofacial structures: the jaw, tongue, and facial muscles (1, 2). Breastfeeding may be the solution to this problem, as the mechanism of breastfeeding can help prevent malocclusion. When compared to bottle-feeding, breastfeeding encourages the palate to adopt the correct shape.

Comparison of single vs double noncompression miniplates in the management of condylar fracture of the mandible Introduction Literature reports that of all the mandibular fracture, 17.5% to 52% occurs in the condyle. Despite recent advances in the field of oral and maxillofacial surgery, the treatment modality for condylar fracture remains to be a topic of discussion and controversy in the field of maxillofacial trauma. Closed reduction had been the choice of treatment for many surgeons but long term complications such as chronic pain, arthritis, open bite, deviation of the mandible on opening and closure inadequate restoration of vertical height which leads to dysocclusion and ankylosis hence causing difficulty in achieving functional and anatomical restoration. This and the advent of miniplate system with the added benefit of early mobilization has turned the focus of many surgeons towards open reduction treatment modalities. Many rigid internal fixation techniques exist for the possible reduction and fixation of the mandibular condyle.

The replacement of missing teeth with fixed partial dentures is largely dependent upon the health and stability of the surrounding periodontal tissues. The gingival tissues should exhibit scalloped margins, sulcus depth within the range of 1–3 mm and an adequate width of attached gingiva. The clinical performance of a crown is directly linked to its mechanical, esthetical, and biological properties. Cementation and marginal integrity play a key role in the long-term prognosis of the treatment.

For various reasons, including deep cavities, too many dental procedures in one area, tooth injuries or cracks, the pulp becomes exposed to the elements. When this happens, food and drink work their way into the delicate pulp and cause an infection. Essentially, the pulp becomes diseased. This leads to extreme pain and swelling, with the possibility that the infection can spread to the rest of the

The latter phenomenon is referred to as malocclusion as a result of trauma and this sensation is felt easily, because the teeth sense even the slightest change in alignment, which generates the sensation of something being wrong. Other signs and symptoms of a mandibular fracture include, obvious deformity, bruising, swelling, numbness due to inferior alveolar nerve compression, and trismus, which is an inability to fully open the mouth. Management While surgery may not necessarily be immediately required in these patients, it is crucial to ensure that the airway is secured, because of the bone’s proximity to the upper respiratory tract and the potential for obstructive complications in an emergency setting. Diagnosis is then followed with the help of imaging.

Description of clinical problem Maxillofacial fractures are usually caused by violence, road traffic accidents, falls, and sports . Pattern and etiology of maxillofacial injuries differ based on geographical, socioeconomic, population mobility, cultural, legislative, and environmental factors . These traumas can cause airway obstruction, intracranial damages, vision loss and other functional deficits . Level 1 of the AO Classification System categorizes the fractures of craniomaxillofacial skeleton into 4 anatomical units: mandible, midface, skull base, and cranial vault . Some high-energy trauma may result in panfacial fractures.

Orthodontics is the branch of dentistry that corrects teeth and jaws that are positioned improperly. Crooked teeth and teeth that do not fit together correctly are harder to keep clean, are at risk of being lost early due to tooth decay and periodontal disease, and cause extra stress on the chewing muscles that can lead to headaches, TMJ syndrome and neck, shoulder and back pain. Teeth that are crooked or not in the right place can also detract from one 's appearance. The benefits of orthodontic treatment include a healthier mouth, a more pleasing appearance, and teeth that are more likely to last a lifetime.
