بررسي تغييرات فاصله بين اكلوزالي با اسپلينت اكلوزالي در افراد داراي دندان طبيعي

Reproducibility of Interocclusal distance with occlusal splint in dentate subjects

Background & Aim: The Interocclusal Distance (IOD) is essential for health of muscles and other parts of masticatory system. It has also a certain rule in esthetics, Function and comfort of patients. Method & Material: In this study the reproducibility of IOD after immediate increase of vertical dimension was evaluated. 16 Dentate subjects with class I occlusion that has no history of tempromandibular and muscle disorders were selected. Full occlusal splints were made for each subject and IOD were measured before and after splint insertion. The Variance and Duncan tests were used to analyze the results. Results: There was no significant difference between 10D before and after splint insertion. Conclusion: It seems that muscles can adapt with increasing of vertical dimension and these changes have no effect on IOD.
