Abstract

Background: Zygomatic implants have been used to treat severe atrophy maxilla. Since its description, the technique has been improved in order to reduce patient morbidity as well as prosthesis rehabilitation time. Despite the improvements in the procedure, zygomatic implant treatments still have complications related to the peri-implant soft-tissue; a probing depth greater than 6 millimeter (mm) and a prevalence of bleeding on probing of 45% have been described. The mobilization of the buccal fat has been used to manage different oral and maxillofacial soft-tissue pathologies. The aim of this study was to assess whether the buccal fat pad might prevent mucosal dehiscence and avoid potential postoperative complications when is placed covering the body part of the zygomatic implants.

Material and methods: In this pilot study, 7 patients were enrolled and a total of 28 zygomatic implants were placed and evaluated during a 12-month follow-up period. Surgical sites were randomly divided into two groups before implant placement: control group (A; in which no buccal fat pad was applied) and experimental group (B). Peri-implant soft tissue thickness difference, pain using a Visual Analog Scale (VAS), swelling, hematoma, buccal soft tissue healing and sinusitis, were evaluated. The implant survival rate was determined according the Aparicio success criteria and compared between the control and experimental procedure.

Results: A nonstatistical difference was found between groups regarding to pain. The experimental group showed higher soft-tissues thickness (p= 0.03) and the implant survival rate was 100% in both groups.

Conclusions: The mobilization of the buccal fat pad to cover the body of the zygomatic implants increases peri-implant soft-tissue thickness, without increasing the postoperative pain.

颊脂肪垫在预防颧种植术后并发症中的作用:一项初步研究。
背景:颧骨种植体已被用于治疗严重的上颌骨萎缩。自其描述以来,该技术已得到改进,以减少患者的发病率和假体康复时间。尽管手术方法有所改进,颧骨植入治疗仍然存在与植入体周围软组织相关的并发症;探查深度大于6毫米(mm),探查时出血的发生率为45%。颊脂肪的动员已被用于管理不同的口腔和颌面软组织病变。本研究的目的是评估颊脂肪垫是否可以防止粘膜开裂,并避免潜在的术后并发症,当它被放置在颧种植体的身体部分。材料和方法:在这项初步研究中,7名患者入组,在12个月的随访期间,共放置28个颧骨植入物并进行评估。植入前将手术部位随机分为两组:对照组(A组;无颊脂肪垫组(B)和实验组(B)。对种植体周围软组织厚度差、疼痛(视觉模拟评分法)、肿胀、血肿、颊软组织愈合和鼻窦炎进行评估。根据Aparicio成功标准确定种植体成活率,并与对照和实验方法进行比较。结果:两组间疼痛程度无统计学差异。实验组软组织厚度高于对照组(p= 0.03),两组种植体成活率均为100%。结论:颊脂肪垫的动员覆盖颧种植体增加种植体周围软组织厚度,不增加术后疼痛。
