The placement of implants into fresh extraction sockets was introduced in 1970. This approach has been reviewed extensively during the past decade. Immediate postextraction implant placement is a well-accepted protocol. The concept of placement of dental implants soon after the removal of a tooth in smokers, however, is still a matter of controversy.
(i) To access failure rate of dental implant in smokers (ii) To evaluate added advantage of plasma rich in growth factors (PRGFs) in immediate placement of dental implants in smokers.
The sample of 30 patients was obtained from the different Outpatient Department of Faculty of Dental Sciences; King George's Medical University, Lucknow, who had visited for rehabilitation of missing teeth by implants between April 2013 and July 2015. They were randomly divided into two groups (without use of PRGF and with use of PRGF) of 15 each. Pre- and postoperative assessment included a thorough history and clinical examination, regression of pain and swelling, implant stability by resonance frequency analysis (RFA), and implant stability according to the bone type as well as radiographic interpretation for measurement of bone loss on the mesial and distal surfaces of the implant.
In this study, pain and swelling were significantly ( < 0.05) higher in Group A than in Group B across the time interval. RFA score for implant stability was lower in Group A across the period than Group B. At the end of 3 months, RFA score (mean) in Group A was having 72.55 ISQ value, and in Group B, it was 75.71 ISQ value. In this study, postoperative crestal bone loss was more in patients in Group A as compared to patients in Group B. There was significant difference in mesial ( = 0.003) and distal ( = 0.001) crestal bone loss at 6 months between the groups.
The immediate placement of dental implants in smokers with use of PRGF is shown to be efficient in relation to postoperative pain and swelling, stability, stability according to bone type, as well as bone loss.
1970年开始采用在新鲜拔牙窝植入种植体的方法。在过去十年中，这种方法得到了广泛的审视。拔牙后即刻种植是一种被广泛接受的方案。然而，在吸烟者拔牙后不久就植入牙齿种植体这一概念仍存在争议。
（i）评估吸烟者牙种植体的失败率（ii）评估富含生长因子的血浆（PRGFs）在吸烟者即刻种植牙种植体中的附加优势。
样本来自勒克瑙乔治国王医科大学牙科学院不同门诊部的30例患者，这些患者在2013年4月至2015年7月期间因牙齿缺失前来进行种植修复。他们被随机分为两组（不使用PRGF组和使用PRGF组），每组15人。术前和术后评估包括全面的病史和临床检查、疼痛和肿胀的消退情况、通过共振频率分析（RFA）评估种植体稳定性、根据骨类型评估种植体稳定性以及通过影像学解释测量种植体近中和远中表面的骨吸收情况。
在本研究中，在整个时间间隔内，A组的疼痛和肿胀程度显著高于B组（<0.05）。在整个期间，A组种植体稳定性的RFA评分低于B组。在3个月末，A组的RFA评分（平均值）为72.55 ISQ值，B组为75.71 ISQ值。在本研究中，A组患者术后牙槽嵴骨吸收比B组患者更多。两组在6个月时近中（=0.003）和远中（=0.001）牙槽嵴骨吸收存在显著差异。
在吸烟者中使用PRGF即刻植入牙种植体在术后疼痛和肿胀、稳定性、根据骨类型的稳定性以及骨吸收方面显示出有效性。
