研究目的:

以自然愈合为对照,评价自体牙骨粉在重度慢性牙周炎患牙位点保存中的作用  

Objectives of Study:

To evaluate the clinical efficacy of alveolar ridge preservation (ARP) using autogenous partially demineralized dentin matrix (APDDM) in periodontally compromised socket compared with spontaneous healing (SH).

药物成份或治疗方案详述:

本研究是一项随机对照研究,研究分为两组:(1)实验组:拔牙窝内放置自体牙骨粉,骨粉上方覆盖胶原蛋白海绵(可即邦,中国)(2)对照组:拔牙窝内不放置任何材料,待其自然愈合。招募的受试者按照随机化表格随机分组,完成入组标准核查、签署知情同意书及相关术前检查后择期手术。拍摄拔牙位点术前、术后即刻和术后4个月的CBCT影像,并记录术前和术后4个月的角化龈宽度,对比分析术前、术后4个月CBCT的相关指标和角化龈宽度的差异并进行统计学分析。两组最终行种植修复的受试者种植术中取部分种植位点少量新生骨进行组织学分析。 

Description for medicine or protocol of treatment in detail:

A total of 30 patients with 32 periodontally compromised teeth were included in this study. The height and width of the extraction socket before tooth extraction and 4 months after preservation were measured. Tephine cores were harvested for histomorphometric evaluation during implant placement. 

纳入标准:

(1)患者年龄≥18岁,既往体健,无诉系统性疾病;
(2)存在因重度慢性牙周炎引起的牙槽骨严重破坏而保留无望的患牙;
(3)患牙拔除后拔牙窝牙槽骨吸收至根中1/2及以下,且剩余高度≥3mm;
(4)至少存在一颗邻牙;
(5)患者依从性良好,经过完善的牙周基础治疗后全口菌斑指数小于20%,全口BOP%<25%;
(6)同意参加本临床试验并签署知情同意书。

Inclusion criteria

The inclusion criteria were as follows: (1)Adult patients (>18 years old), systemically healthy; (2)Presence of a periodontally compromised hopeless molar requiring extraction; (3)Alveolar bone resorption more than half the length of the tooth root; presence of at least one adjacent natural tooth; post-extractive sites alveolar bone with at least two residual bone wall heights >= 3 mm;(4)Presence of at least one adjacent tooth; (5)The patients is with good compliance. After the periodontal treatment, the whole mouth plaque index was less than 20%, and the whole mouth BOP% was less than 25%.(6)Compliance with study-related procedures and signed the informed consent form.

排除标准:

(1)患牙或邻牙有急性感染;
(2)女性患者在妊娠期或哺乳期;
(3)3个月内服用过影响血小板或骨再生功能的药物;
(4)有头颈部放射治疗史及全身系统性疾病未控制者;
(5)重度吸烟者,吸烟量>10支/日。

Exclusion criteria:

The exclusion criteria were as follows: (1) Acute infection of the affected or adjacent teeth;(2) Female patients during pregnancy or lactation;(3)Patients who taken drugs affecting platelet or bone regeneration within 3 months;(4) History of head and neck radiotherapy, uncontrolled systemic diseases;(5) Heavy smokers, smoking more than 10 cigarettes/day.

随机方法(请说明由何人用什么方法产生随机序列):

在受试者签署知情同意书后,并符合所有入选标准且不符合任一排除标准时,受试者将被纳入本次临床试验。采用系统生成一个种子数,设置样本量和区组长度,由 PROC PLAN 过程,生成试验所需的随机数字表,导入随机系统。由研究者登录中央随机系统,录入受试者信息,根据随机系统分组,将受试者随机分配到试验组或对照组,试验组和对照组的比例为 1:1。

Randomization Procedure (please state who generates the random number sequence and by what method):

After the subject signs the informed consent, and meets all the inclusion criteria and does not meet any exclusion criteria, the subject will be included in this clinical trial. A seed number is generated by the system, the sample size and block length are set, and the random number table required

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

由于研究者可目视下区别试验产品与对照产品,不能对研究者设盲,因此只对受试者进行设盲,故采用单盲设计,即受试者盲。

Blinding:

Since the researcher can visually distinguish the test product from the control product, the researcher cannot be blinded, so only the subjects are blinded, so the single blind design is adopted, that is, the subjects are blind.
