Abstract

Objectives: To report one-year outcomes of prosthetic rehabilitation of the atrophic maxillae, supported by angled abutments on zygomatic implants and conventional implants.

Methods: In the present retrospective analysis, edentulous maxillary areas treated with fixed-hybrid prostheses supported by angled abutments of 45, 52.5, and 60 degrees screwed to zygomatic implants inserted using an extrasinus surgical approach were included. Prosthesis, implant, and abutment success/survival rates, complications, Mucosal Seal Efficacy Evaluation (MSEE), modified PLaque Index (mPLI), modified Bleeding Index (mBI), and Zygomatic Implants Classification Level (ZICL) were assessed.

Results: Ninety-eight straight implants and 81 zygomatic implants (21 abutments of 45 degrees, 23 of 52.5 degrees, and 37 of 60 degrees) were inserted into 35 patients. Biological complications: postoperative sinus opacity was observed in seven patients, two of whom experienced a unilateral perforation of the sinus membrane. ZICL0-1 was recorded in 95% of zygomatic sites; the cumulative success rates were 100% and 94.3% when using the implant and prosthesis as units of analysis, respectively.

Conclusion: Survival rate for the implants attested to the highest percentage (100%), whereas survival rate of the prostheses was 94.3%. No differences were registered among the clinical indices related to different inclinations of the abutments.

传统和颧骨种植体混合全弓康复：短期回顾性分析。

目的：报道在颧种植体和常规种植体上采用角度基台支持的萎缩上颌的一年内修复效果。方法：回顾性分析上颌无牙区采用固定-混合假体，分别采用45度、52.5度和60度角基台与颧种植体螺钉固定，经鼻外入路植入。评估假体、种植体和基台的成功率/存活率、并发症、粘膜密封疗效评估（MSEE）、改良斑块指数（mPLI）、改良出血指数（mBI）和颧种植体分类水平（ZICL）。结果：35例患者共植入直种植体98个，颧种植体81个，其中45度牙基21个，52.5度牙基23个，60度牙基37个。生物学并发症：术后7例患者出现鼻窦混浊，其中2例出现单侧鼻窦膜穿孔。95%的颧骨部位有ZICL0-1；以种植体和假体为分析单位，累积成功率分别为100%和94.3%。结论：种植体成活率最高（100%），假体成活率为94.3%。与基牙不同倾斜度相关的临床指标无统计学差异。
