Abstract
PURPOSE
To investigate the effectiveness of combined orthodontic and restoration treatment for introverted deep overbite patients with severe wear.
METHODS
A total of 86 introverted deep overbite patients with severe wear admitted to Cangzhou People's Hospital from December 2020 to June 2022 were collected and divided into the control group and the experimental group by gender, age, degree of wear and tear, with 43 cases in each group. The control group received orthodontic treatment, while the experimental group received combined orthodontic and restoration treatment. The gingival index (GI), periodontal index(PI), smile index, temporomandibular joint space [anterior space, superior space, posterior space and In (P/A)], tooth function (chewing function, pronunciation function, dental occlusal function) and chewing efficiency of 2 groups before and after treatment were compared. Statistical analysis was performed with SPSS 22.0 software package.
RESULTS
Compared with the control group, the orthodontic treatment time of the experimental group patients was significantly reduced(P＜0.05). Before treatment, there was no significant difference in GI, PI, smile index, buccal gap rate, temporomandibular joint space, swallowing function and chewing efficiency between 2 groups(P＞0.05). After treatment, compared with the control group, the GI, PI, anterior space were significantly reduced(P＜0.05); the smile index, posterior space and In (P/A), chewing function, pronunciation function, tooth occlusion and chewing efficiency significantly increased (P＜0.05).
CONCLUSIONS
Both orthodontic treatment and combined orthodontic and restoration treatment can be used to treat introverted deep overbite patients with severe wear. However, combination of orthodontic and restoration treatment has significant advantages.
