occlusal trauma

Any injury to part of the masticatory system as a result of malocclusion or occlusal dysfunction. It may be abrupt in its development in response to a restoration or ill-fitting prosthetic device, or result from years of tooth wear, drift, or faulty oral habits. It may produce adverse periodontal changes, tooth mobility or excessive wear, pain in the temporomandibular joints, or spasms and pain in the muscles of mastication.

Further, there was widening of the periodontal space in the right maxillary lateral dentition, which is a characteristic of occlusal trauma. Therefore, this patient was investigated using the BC with the aim of visualizing and assessing the cause of the occlusal trauma (Figure 4(a)), which is considered to be a factor exacerbating periodontitis [5, 6].
Based on this information, investigating this condition based on the results of an assessment of occlusion function with the BC and periodontal examination is considered effective in enabling occlusal treatment goal clarification through orthodontic treatment in cases of periodontal disease associated with occlusal trauma, as in the present case.
Generally associated with occlusal trauma where the anatomic crown of the tooth has flexure.
One of the possible contributing factors for tooth wear can also be periodontal diseases which can alter tooth mobility therefore changing the interocclusal contacts.18 Although the exact causative mechanism is not yet known, occlusal trauma resulting in such cases can act as aggravating factors for existing periodontal problems causing a cascade of tooth destructive mechanisms.
Preoperative radiographs showing severe interdental bone loss and widening of the residual periodontal ligament space as a consequence of the occlusal trauma (c).
Occlusal trauma has been defined as 'injury to the periodontium resulting from occlusal forces which exceed the reparative capacity of the attachment apparatus': i.e.
Moreover, tipping9, tilting and physiological drift- ing10 may adversely affect the relative crown-root alignment7,9 resulting in unfavorable occlusal forces which may lead to periodontal breakdown or occlusal trauma.11 In younger age group, the undesirable tooth movements are more profound due to greater potential for growth.12 Majority of them occur in the early post extraction periods.13 Loss of periodontal support may superimpose later as reinforced by Ainamo and Ainamo in 1978.14
