Abstract

Purpose: To evaluate early versus conventional loading in immediate implants for molars. This study aims to answer the following PICO (Patient, Intervention, Comparison, and Outcome) question: In patients over 18 years of age, does early loading of immediately placed implants in molar areas result in a similar implant survival rate and marginal bone loss as conventional loading?

Methods: Twenty-seven patients (15 women and 12 men) received a total of 30 implants immediately after molar extraction. The surgical treatment protocol entailed atraumatic tooth extraction without flap elevation. Non-invasive quantitative analyses were used to assess implant stability. After an uneventful healing period, the 30 implants were restored with screw-retained monolithic zirconia prosthesis, half of which after 6 weeks (G1) and the other half after 3 months (G2).

Results: Regarding the survival rate, the Kaplan-Meier and log-rank test showed that there was no statistically significant difference between both groups (p = 1). Implant stability quotient at the prosthetic phase of both groups (6 weeks in G1 and 3 months in G2) revealed no statistically significant difference (G1 RFA74.4 (SD 5.54) - DCA 79.07 (SD 5.75))/G2 RFA 73.67 (SD 5.7), - DCA78.93 (SD 4.48).

Conclusions: Early loading of immediately placed implants in molar sites is considered a predictable treatment modality provided that ideal implant position and adequate insertion torque are achieved.

早期与常规加载完全引导即刻种植体放置在磨牙部位：一项随机对照临床研究。

目的：评价磨牙即刻种植体早期负荷与常规负荷的比较。本研究旨在回答以下PICO（患者，干预，比较和结果）问题：在18岁以上的患者中，在磨牙区域立即放置种植体的早期装填是否会导致种植体存活率和边缘骨质流失与常规装填相似？方法：27例患者（女性15例，男性12例）在拔牙后即刻种植30颗。手术治疗方案包括无皮瓣抬高的无伤性拔牙。采用无创定量分析评估种植体稳定性。经过一段平静的愈合期后，30个种植体使用螺钉保留的整体氧化锆假体修复，其中一半在6周（G1）后修复，另一半在3个月（G2）后修复。结果：生存率经Kaplan-Meier和log-rank检验，两组间差异无统计学意义（p = 1）。两组（G1组6周，G2组3个月）假体期种植体稳定性商差异无统计学意义(G1 RFA74.4 (SD 5.54) - DCA 79.07 (SD 5.75))/G2 RFA 73.67 (SD 5.7), - DCA78.93 （SD 4.48）。结论：只要获得理想的种植体位置和足够的插入扭矩，立即放置种植体的早期加载被认为是一种可预测的治疗方式。
