摘要

目的:牙周炎是由龈下细菌菌群失调引起的炎症,导致炎症介导的牙齿支持结构破坏,并可能形成牙槽骨下缺损。本病例报告描述了对一名 21 号牙 1-2 壁联合缺损患者的治疗。为了维持残余的牙周附着并尽量减少美观后果,我们使用重组人血小板衍生生长因子-BB(rh-PDGF-BB)和β-磷酸三钙(β-TCP)进行了再生治疗:一名 34 岁的亚裔男性在进行洗牙/根面平整术后复查时,初步诊断为臼齿/incisor 模式 III 期 C 级牙周炎,其第 21 号牙齿中腭侧的探诊深度残留 6 毫米。在不使用牙膜的情况下,使用 rh-PDGF-BB 和 β-TCP进行了牙周再生手术:随访 1 年后,探诊深度明显降低,X 光片显示骨填充。此外,在第 23 颗牙齿部位再次进行种植手术时,证实了第 21 颗牙齿缺损处的骨填充情况:这些结果表明,rh-PDGF-BB 和 β-TCP 能有效促进牙周再生,并支持将其作为治疗美观区内骨缺损的一种治疗方法。

Optimizing esthetic zone periodontal regeneration in a 1–2-wall infrabony defect using recombinant human platelet-derived growth factor BB and β-tricalcium phosphate: A case report

Objective

Periodontitis is an inflammatory condition induced by subgingival bacterial dysbiosis, resulting in inflammatory-mediated destruction of tooth-supporting structures, potentially leading to the formation of infrabony defects. This case report describes the treatment of a patient who presented with a combination 1–2-wall defect on tooth 21. To maintain the residual periodontal attachment and minimize esthetic consequences, a regenerative approach was performed using recombinant human platelet-derived growth factor-BB (rh-PDGF-BB) and β-tricalcium phosphate (β-TCP).

Materials and Methods

At the time of postscaling/root planing reevaluation, a 34-year-old Asian male initially diagnosed with molar/incisor pattern stage III grade C periodontitis exhibited a 6-mm residual probing depth on the mesiopalatal aspect of tooth 21. Periodontal regenerative surgery was performed using rh-PDGF-BB with β-TCP, without the use of a membrane.

Results

At the 1-year follow-up, a significant reduction in probing depth and radiographic evidence of bone fill were observed. Additionally, re-entry surgery for implant placement at site tooth 23 confirmed bone fill in the defect on tooth 21.

Conclusion

These results demonstrate the efficacy of rh-PDGF-BB with β-TCP in enhancing periodontal regeneration and support its use as a treatment option when treating poorly contained infrabony defects in the esthetic zone.

期刊介绍: Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
