The aim of this prospective clinical trial was to examine the predictability of the protocol for premolar transplantation when applied by an inexperienced surgeon. Additional objectives were to examine the hard and soft tissues and to compare the findings with control premolars and also to record the patients' opinions of the treatment provided.
The sample comprised 23 consecutively transplanted developing premolars in 19 patients. Their mean age at surgery was 12 years 8 months (range, 9 years 10 months-17 years). The mean observation time was 35 months (range, 6-78 months). Plaque accumulation, pocket depth, gingival recession, mobility, and pulp sensitivity were recorded for the transplanted and the control teeth. Standardized radiographs were used to examine hard tissues and crown-to-root ratios. Questionnaires were used to register each patient's opinion about the treatment and its outcome.
The survival rate was 100%, and the success rate was 91.3%. No significant differences were recorded between transplanted and control teeth. The patients' perceptions of the surgical management and the treatment outcome were favorable.
The protocol for autotransplantation of developing premolars in growing patients was successfully adopted, regardless of lack of previous experience with this type of treatment.
本前瞻性临床试验旨在检验经验不足的外科医生应用该方案进行前磨牙移植的可预测性。此外，还将检查硬组织和软组织，并将结果与对照前磨牙进行比较，同时记录患者对所提供治疗的意见。
该样本包括 19 名患者的 23 颗连续移植的发育中前磨牙。手术时的平均年龄为 12 岁 8 个月（范围为 9 岁 10 个月至 17 岁）。平均观察时间为 35 个月（范围为 6-78 个月）。记录移植牙和对照牙的菌斑积聚、牙周袋深度、牙龈退缩、松动度和牙髓敏感度。使用标准化的 X 光片检查硬组织和冠根比。调查问卷用于记录每位患者对治疗及其结果的看法。
存活率为 100%，成功率为 91.3%。移植牙与对照牙之间未记录到显著差异。患者对手术管理和治疗效果的看法是积极的。
尽管缺乏此类治疗的经验，但生长中的患者自体前磨牙移植方案的应用是成功的。
