本病例报告的目的是评估Partsch I膀胱切开术的使用，以保存位于牙源性囊肿的种植体，范围从3.2到4.4。女性，50岁，右侧下颌骨可见圆形、清晰的单眼透光区，面积约2.5 cm，内嵌口腔种植体。下颌骨右侧覆盖义齿无临床活动能力。作者决定进行手术治疗以保存植入物。患者接受了Partsch I手术，随后每周更换碘仿纱布插入，持续一个月，修改之前的正畸根管治疗，并在接下来的两个月应用丙烯酸树脂闭孔假体。12个月的随访显示右侧下颌外侧种植体无临床活动能力。影像学分析显示囊性病变愈合，种植体周围骨再生。本报告强调了当囊肿涉及种植体并破坏其稳定性时，应用膀胱切开术的机会。这种可能性是由特殊的临床情况提供的，植入物是由以前的假体固定的存在而稳定的。我们的研究导致了一种手术方案的应用，允许保存种植体。
The aim of this case report was to evaluate the use of Partsch I cystotomy in order to preserve a dental implant located in an odontogenic cyst extended from 3.2 to 4.4. A 50 year-old woman showed a circular, well-defined unilocular radiolucent area, O2.5 cm, in the right mandibular region with an oral implant intruding inside it. The overdenture in the mandibular right site showed no clinical mobility. The authors decided to perform a surgical treatment aimed to preserve the implant. The patient underwent Partsch I surgery followed by iodoform gauze insertion replaced weekly for one month, revision of the previous orthograde endodontic treatments, and an acrylic resin obturator prosthesis application for the following two months. The twelve month follow-up showed no clinical mobility of the right lateral mandibular implant prostheses. Radiographical analysis revealed cystic lesion healing and perimplant bone regeneration. This report highlights the opportunity to apply cystotomy when the cyst involves a dental implant and undermines its stability. This possibility is offered by the peculiar clinical scenario where the implant was stabilized by the presence of a previous prosthetic fixation. Our study led to the application of an operative protocol that allowed for the preservation of the implant.
