Abstract:
The concept of bilateral cantilevers on a single central implant (T-design) for three-unit implant-supported fixed dental prostheses (ISFDPs) has not been explored nor tested. This technical hypothesis aimed to explore the feasibility of such an approach as a cost-effective alternative to conventional treatments. Careful considerations regarding implant diameter, length, ideal position, occlusal scheme, and bone remodeling are essential to ensure adequate support, stability, and prevention of complications. In this proof of concept, we present a preliminary case with this novel design to replace missing posterior teeth in a patient with narrow bone conditions. In addition, a series of planned investigations and preliminary results, including preclinical studies, are presented to illustrate our concept and its potential clinical implications. Clinically, after two-year follow-up, healthy and stable peri-implant tissues around the ISFDP exemplarily demonstrated excellent stability, functionality, and comfort, which is supported by acceptable fracture resistance data in vitro, suggesting indeed the practical potential and suitability. Thus, we claim that such a treatment modality has the at least theoretical potential to revolutionize implant dentistry by providing innovative and cost-effective treatment options for patients with partial ISFDPs in very specific cases. Of course, further research and evaluations are necessary to validate the clinical implications of this innovative hypothesis. Implementing the 3-on-1 T-bridge approach in partial ISFDPs could offer a promising alternative to traditional methods. If proven successful, this technique may lead to significant advancements in clinical practice, providing a less invasive cost-effective treatment option.
摘要:
尚未探索或测试用于三单元植入物支撑的固定假牙(ISFDP)的单个中央植入物(T设计)上的双侧悬臂的概念。该技术假设旨在探索这种方法作为常规治疗方法的成本效益高的替代方法的可行性。仔细考虑植入物直径,长度,理想位置,咬合方案,骨骼重建对于确保足够的支持至关重要,稳定性,预防并发症。在这个概念证明中,我们提出了一个初步的案例,采用这种新颖的设计来替代骨骼狭窄患者的后牙缺失。此外,一系列计划调查和初步结果,包括临床前研究,介绍了我们的概念及其潜在的临床意义。临床上,经过两年的随访,ISFDP周围的健康和稳定的种植体周围组织示例性地表现出优异的稳定性,功能,和舒适,这得到了体外可接受的抗断裂性数据的支持,确实表明了实际的潜力和适用性。因此,我们声称,这种治疗模式至少在理论上具有革命性的潜力,在非常特殊的病例中为部分ISFDP患者提供创新且具有成本效益的治疗方案.当然,需要进一步的研究和评估来验证这一创新假设的临床意义.在部分ISFDP中实施3对1T桥方法可以为传统方法提供有希望的替代方案。如果证明成功,这种技术可能会导致临床实践的重大进展,提供一种侵入性较低的成本有效的治疗选择。
