Abstract

Purpose: The present study aimed to evaluate the appropriate protocol to be followed in the maxillary esthetic zone involving single dental implants by comparing three implant placement protocols: immediate implant placement (IIP) with and without the socket shield technique (SST) and delayed implant placement (DIP) in terms of dynamic alterations in hard and soft tissues and patient-related outcome measures (PROMS).

Materials and methods: A total of 75 patients were recruited for the study and randomly allocated to the SST, IIP, and DIP groups (25 each). They were subjected to Cone Beam Computed Tomography (CBCT) assessment pre-operatively, 6 and 12 months post-operatively to evaluate changes in Crestal Bone Thickness (CBT). Soft tissue changes were evaluated using the pink aesthetic score (PES) and visual analogue scale (VAS) to assess the pain threshold and patient satisfaction.

Results: There was a statistically significant difference in the mean reductions in crestal bone thickness (CBT) between and among the groups. The SST group demonstrated a significantly lower reduction in CBT (0.09) than the IIP and DIP groups, which showed a mean reduction in CBT of 0.18 and 0.50 at (p<0.01), respectively, at the end of 12 months. However, when the mean differences in PES between the groups were compared, there was a statistically significant difference for SST 13(2), IIP 10(2), and DIP 9(2) (p<0.01).

Conclusion: Socket shield technique could be technique of choice for IIP when buccal bone thickness is <1mm as demonstrated by less reduction in CBT and better PES at the end of 12 months than the IIP and DIP groups.

上颌美观区I型拔牙槽种植时机的评价-一项随机对照试验。
目的:本研究旨在通过比较三种种植体种植方案:即刻种植体种植(IIP)与不使用窝窝保护技术(SST)和延迟种植体种植(DIP)在软硬组织的动态变化和患者相关结果测量(PROMS)方面,评估上颌美观区适用的合适方案。材料与方法:共招募75例患者,随机分为SST组、IIP组和DIP组(各25例)。术前、术后6个月和12个月接受锥形束计算机断层扫描(CBCT)评估,以评估冠骨厚度(CBT)的变化。采用粉红色美学评分(PES)和视觉模拟评分(VAS)评估软组织变化,评估疼痛阈值和患者满意度。结果:两组间冠骨厚度(CBT)的平均减少量差异有统计学意义。SST组的CBT降低率(0.09)明显低于IIP组和DIP组,IIP组的CBT平均降低率分别为0.18和0.50 (p)。结论:当颊骨厚度达到一定水平时,窝窝屏蔽技术可作为IIP治疗的首选技术
