目标

评估微螺钉辅助快速扩腭（MARPE）对上颌中切牙牙间乳头高度的影响。

材料和方法

本回顾性研究纳入了 2018 年至 2021 年间在拉德堡德大学医学中心完成 MARPE 治疗的患者。使用 Jemt 分类，根据扩张前 (T0) 和 MARPE 治疗后 1.5 年 (T1) 拍摄的额部口内照片评估上颌中切牙之间的乳头高度。T0 和 T1 时 Jemt 评分的差异是主要结果变量。此外，性别、年龄、角度分类、MARPE持续时间、腭中缝成熟阶段、扩张后立即最大中央纵裂（MCD）、牙冠宽长比（W/L）、治疗前上颌中切牙的重叠以及之间的距离还记录了中切牙和骨嵴的近接触点（CP-B）。

结果

纳入 22 名患者（2 名男性，20 名女性，平均年龄 27.3 ± 8.8 岁），4 名患者 (18%) 在 MARPE 后显示 Jemt 评分显着降低 (p = 0.04)，表明乳头衰退。牙间乳头后退与 CP-B 的增加 ( p = 0.02)、较小的 W/L ( p < 0.01)、上颌中切牙重叠 ( p < 0.01) 以及扩张后立即较小的 MCD ( p = 0.02 ) 显着相关）。

结论

MARPE 一年半后，18% 的患者出现上颌中切牙乳头高度轻度退缩。上颌中切牙重叠和较小的W/L是牙间乳头退缩的预后因素。

临床相关性

临床医生必须了解并告知患者 MARPE 后乳头退缩的发生。

Influence of miniscrew-assisted rapid palatal expansion (MARPE) on the interdental papilla height of maxillary central incisors

Objectives

To evaluate the influence of miniscrew-assisted rapid palatal expansion (MARPE) on the interdental papilla height of maxillary central incisors.

Materials and methods

Patients who completed MARPE treatment at the Radboud University Medical Center between 2018 and 2021 were included in this retrospective study. The papilla height between the maxillary central incisors was evaluated on frontal intraoral photographs taken before expansion (T0) and 1.5 years after MARPE treatment (T1) using the Jemt classification. The difference in Jemt score at T0 and T1 was the primary outcome variable. In addition, gender, age, Angle classification, MARPE duration, midpalatal suture maturation stage, maximal central diastema (MCD) immediately after expansion, crown width to length ratio (W/L), pretreatment overlap of maxillary central incisors, and the distance between the approximal contact point of the central incisors and the bone crest (CP-B) were also record.

Results

Twenty-two patients were included (2 men, 20 women, mean age 27.3 ± 8.8 years) and 4 patients (18%) showed a significant reduction in the Jemt score following MARPE (p = 0.04), indicating papilla recession. Interdental papilla recession was significantly associated with the increase of CP-B (p = 0.02), smaller W/L (p < 0.01), overlapping of maxillary central incisors (p < 0.01), and smaller MCD immediately after expansion (p = 0.02).

Conclusions

One and a half years after MARPE, 18% of patients exhibited mild recession of papilla height of the maxillary central incisors. Overlapping and smaller W/L of maxillary central incisors were prognostic factors for interdental papilla recession.
