Effects of Anterior Bite Turbos on Deep Bite Treatment and Chewing Muscles
Evaluation of the Effects of Anterior Bite Turbo Application During Deep Bite Treatment on Dentoalveolar and Skeletal Structures and Masticatory Muscles
This study evaluated how anterior bite turbos used during orthodontic treatment of deep bite affect chewing muscle activity and dental and skeletal measurements. Participants were followed in two nonrandomized groups: one received anterior bite turbos as part of orthodontic treatment, and the other received orthodontic treatment without bite turbos. Surface electromyography (EMG) was used to measure muscle activity over time. Cephalometric measurements were also evaluated to assess treatment-related changes.
調査の概要
詳細な説明
This prospective, nonrandomized, two-group study examined patients undergoing orthodontic treatment for deep bite. Anterior bite turbos were applied in one group; the comparison group underwent orthodontic treatment without anterior bite turbos during the study period.
Surface EMG recordings of the right and left masseter, anterior temporalis, and anterior digastric muscles were obtained at rest and during maximum voluntary clenching. Both groups were assessed before treatment, at approximately one month, and at approximately six months. The bite turbo group also underwent an EMG assessment immediately after bite turbo placement. Cephalometric measurements were evaluated at baseline and approximately six months.

実験的：Anterior Bite Turbo Group
Participants received anterior bite turbos as part of fixed orthodontic treatment for deep bite. Surface EMG and orthodontic measurements were obtained during follow-up. |
Composite resin bite turbos were bonded to the palatal surfaces of the maxillary central incisors during fixed orthodontic treatment. The bite turbos were used to disclude the posterior teeth during deep bite treatment. Participants received fixed orthodontic treatment for deep bite. |

アクティブコンパレータ：No Bite Turbo Group
Participants received fixed orthodontic treatment without anterior bite turbos during the study period. Surface EMG and orthodontic measurements were obtained during follow-up. |
Participants received fixed orthodontic treatment for deep bite. |

Change in Mean Bilateral Masseter Muscle Activity at Rest
時間枠：Baseline (before bite turbo placement), 1 month, and 6 months
|
Surface electromyographic activity of the right and left masseter muscles was recorded at rest. The mean of the two sides, measured in microvolts (µV), was evaluated at baseline, 1 month, and 6 months. Changes over time were compared between the anterior bite turbo and no bite turbo groups. |
