Few studies have reported the outcomes of immediate placement at infected post-extraction sites. The aim of this study was to compare clinical and radiological outcomes of immediately placed implants with immediate prosthetic provisionalization in sockets with or without acute periapical pathology.
A total of 100 patients with immediately placed implants with immediate provisionalization and 1- year of follow up were included (50 patients with acute periapical pathology and a control group of 50 patients without acute periapical pathology). Clinical parameters (bleeding on probing, buccal keratinized mucosa width, clinical recession, and probing depth) and radiological parameters (distance from implant shoulder to first point of bone-to-implant contact [IS-BIC]) were assessed.
Clinical parameters showed no significant differences between the study and control groups after 1-year follow up (p>0.05). IS-BIC presented the following values: 0.35 ± 0.51 mm (study group) and 0.15 ± 0.87 mm (control), without significant differences between the groups (p=0.160). None of the 50 radiographs of immediate implants placed in sockets with periapical pathology revealed retrograde peri-implantitis.
Immediate placement of implants with immediate prosthetic provisionalization at sites with acute periapical pathology can be a successful treatment modality for at least 1-year.
鲜有研究报道过感染拔牙窝内即刻植入的结果。本研究旨在比较有或无急性根尖周病变的拔牙窝内即刻植入即刻修复的临床和影像学结果。
共纳入 100 例即刻植入即刻临时修复并随访 1 年的患者（50 例有急性根尖周病变，对照组为 50 例无急性根尖周病变）。评估临床参数（探诊出血、颊侧角化黏膜宽度、临床退缩、探诊深度）和影像学参数（种植体肩到骨-种植体接触第一点的距离[IS-BIC]）。
1 年后，两组的临床参数均无显著差异（p＞0.05）。IS-BIC 的值分别为：研究组 0.35±0.51mm 和对照组 0.15±0.87mm，两组间无显著差异（p=0.160）。在有根尖周病变的 50 张即刻植入的 X 光片中，无一例出现逆行性种植体周围炎。
在有急性根尖周病变的部位即刻植入并即刻临时修复，至少 1 年的结果是成功的。
