To evaluate the esthetic and functional rehabilitation of single implants delivering the final crown during second-stage surgery.
In 26 single-tooth implants, the impressions were taken immediately after implant placement to fabricate the final crowns. During the second-stage surgery, the screw-retained hybrid crowns were delivered. Six months to 3 years after placement of the crown, a modified pink esthetic score (PES) was measured. Additionally, the number of treatment sessions was recorded. The mesial and distal contact points and the static and dynamic occlusion were examined. Patients' satisfaction was measured using a questionnaire.
In this retrospective study, 21 posterior and 5 anterior implants were included. The average pink esthetic score was 11.3 out of 14. The most frequent limitations were incomplete papillae and deficits of the alveolar ridge. The average number of appointments was three, consisting of impression taking and surgery consent, implant placement, and crown delivery. Average patients' satisfaction was 46.7 out of 50 and thus, extremely high.
The presented approach allows the second-stage surgery and delivery of the final restoration for single-tooth implants in the same session. As the peri-implant mucosa is adapted to the final restoration in the first place, a more natural emergence profile is achieved. However, there is an increasing risk for reduced or missing papillae. Patients' satisfaction is generally very high.
A method for direct definitive prosthetic restoration during the exposure of single-tooth implants is examined, advantages and disadvantages will be described, and patient acceptance is validated.
评估二期手术中即刻戴入最终修复体的单牙种植体的美观和功能恢复效果。
在 26 个单牙种植体中，在植入后立即进行印模制取，以制作最终修复体。在二期手术中，戴入螺丝固位的混合式修复体。在戴冠后 6 个月至 3 年内，测量改良后的粉色美学评分（PES）。此外，记录治疗次数。检查近远中接触点以及静态和动态咬合。使用问卷评估患者满意度。
在这项回顾性研究中，纳入了 21 颗后牙种植体和 5 颗前牙种植体。平均粉色美学评分为 14 分中的 11.3 分。最常见的限制因素是不完全的牙乳头和牙槽嵴的不足。平均预约次数为 3 次，包括取印模和手术同意、种植体植入和修复体戴入。平均患者满意度为 50 分中的 46.7 分，非常高。
所提出的方法允许在同一阶段进行二期手术和最终修复体的戴入。由于首先适应了最终修复体的种植体周围黏膜，因此可以获得更自然的美观效果。然而，存在牙乳头减少或缺失的风险增加。患者满意度普遍非常高。
检查了一种在单牙种植体暴露时即刻进行最终修复的方法，描述了其优缺点，并验证了患者的接受程度。
