Aging of the normal occlusion

Abstract

The aging process slightly deteriorates some occlusal features of individuals with normal occlusion. However, most individuals were satisfied with their aesthetics and occlusal comfort at the sixth decade of life.

Comparison of microesthetic patterns in normal occlusion in relation to class I malocclusion treated with extractions of four premolars

“…This finding has been described in other researches that evaluated the OGS index in untreated and well treated cases. [32][33][34][35] In this study, greater width/height proportions were found compared with those from previous researches. 6,22,26 This may be explained because the widths of the subjects included in this study were larger and consequently influenced the width/height proportion in anterior upper teeth.…”

“…Although the OGS index has been frequently used to analyze the quality of orthodontic treatment finishing, 31 it was also applied in the Normal Occlusion group of this study to make the groups comparable regarding to occlusal quality. 32 One limitation of this study was the absence of panoramic radiographs in Normal Occlusion group. Then, the root angulation parameter from the OGS was excluded in this evaluation.…”

“…This behavior has been previously reported. 32 Other indexes are available to evaluation of occlusion and esthetic, as DAI (Dental Aesthetic Index), although OGS index is a well described, reliable and largely used in orthodontics.…”

Dentoskeletal and tegumental changes in individuals with normal occlusion after a 40-year follow-up

“…3,10,12,17,21,23,24 One of the limitations of performing longitudinal studies is the difficulty in collecting data, which restricts the sample size. 10,21,25,26 (Figs. 2 to 4), confirming that craniofacial growth continued into adulthood as previously reported.…”

Longitudinal evaluation of extraction space closure, at final, medium and long-term, and its association with the adopted protocol, in patients treated in the last 40 years, with several initial malocclusions

“…18 Interproximal contacts have already shown a tendency to improve over time in normal occlusion. 69 This suggests that there would be good longterm perspective of stability when spaces were closed even with the aging of the patients. Nonetheless, studies reporting open spaces at the end of treatment and relating the difficult to obtain only cases with closed spaces to the samples are common and frequent in the literature.…”
