摘要

目的：本研究旨在探讨一种利用人工智能（AI）驱动的牙齿分割和3D打印技术设计和制造密封槽基台（SSA）的新技术。方法：在术前锥形束计算机断层扫描（CBCT）扫描中，使用经过验证的人工智能驱动模块对待替换牙齿进行分割。根据虚拟手术计划，将CBCT和口内扫描（IOS）导入Mimics软件。人工智能切分牙与人工智能切分牙对齐，在临时基牙颈部水平切分，并在龈缘以上2 mm处进一步切分，以捕捉出牙轮廓。一个比临时基台宽2mm的锥形切口，5°锥度，用于被动配合。这个过程产生了一个定制的密封插座基台，然后进行3d打印。在无创伤拔牙和立即种植体放置后，定位临时基台，然后在顶部放置SealPrint。一种可流动的复合材料被用来填补临时基台和SealPrint之间的空隙；整个结构密封拔牙槽，通过设计为牙间乳头提供支持，并保护种植体和使用的（生物）材料。结果：按照计划，SealPrint被动贴合在临时基台上。它为拔牙槽的整个表面提供了最佳的密封，保留了拔牙的出现轮廓，保护了牙齿种植体，稳定了移植材料和血凝块。结论：SealPrint技术提供了一种可靠和快速的解决方案，用于保护和保存软、硬组织和立即植入后的出现剖面。

SealPrint: The anatomically replicated seal-and-support socket abutment technique A Proof-of-Concept with 12 months of follow-up

Objectives

This study aimed at investigating a novel technique for designing and manufacturing a sealing socket abutment (SSA) using artificial intelligence (AI)-driven tooth segmentation and 3D printing technologies.

Methods

A validated AI-powered module was used to segment the tooth to be replaced on the presurgical Cone Beam Computed Tomography (CBCT) scan. Following virtual surgical planning, the CBCT and intraoral scan (IOS) were imported into Mimics software. The AI-segmented tooth was aligned with the IOS, sliced horizontally at the temporary abutment's neck, and further trimmed 2 mm above the gingival margin to capture the emergence profile. A conical cut, 2 mm wider than the temporary abutment with a 5° taper, was applied for a passive fit.

This process produced a custom sealing socket abutment, which was then 3D-printed. After atraumatic tooth extraction and immediate implant placement, the temporary abutment was positioned, followed by the SealPrint atop. A flowable composite was used to fill the gap between the temporary abutment and the SealPrint; the whole structure sealing the extraction socket, providing by design support for the interdental papilla and protecting the implant and (bio)materials used.

Results

True to planning, the SealPrint passively fits on the temporary abutment. It provides an optimal seal over the entire surface of the extraction socket, preserving the emergence profile of the extracted tooth, protecting the dental implant and stabilizing the graft material and blood clot.

Conclusions

The SealPrint technique provides a reliable and fast solution for protection and preservation of the soft-, hard-tissues and emergence profile following immediate implant placement.

期刊介绍： The Journal of Dentistry has an open access mirror journal The Journal of Dentistry: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The Journal of Dentistry is the leading international dental journal within the field of Restorative Dentistry. Placing an emphasis on publishing novel and high-quality research papers, the Journal aims to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. Topics covered include the management of dental disease, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research. The Journal of Dentistry will publish original scientific research papers including short communications. It is also interested in publishing review articles and leaders in themed areas which will be linked to new scientific research. Conference proceedings are also welcome and expressions of interest should be communicated to the Editor.
