研究目的:

主要目标是研究一种新型胶原基质材料(Mucograft Seal)用于前牙美学区牙槽嵴保存术中代替自体腭部软组织移植以实现软组织增强的可行性及效果, 为临床中前牙美学区牙列缺损患者软组织管理提供可选择的替代治疗方案。  

Objectives of Study:

The primary objective of this study is to evaluate the feasibility and effectiveness of using a novel collagen matrix material (Mucograft Seal) as a substitute for autogenous palatal soft-tissue grafts to achieve soft-tissue augmentation during alveolar ridge preservation in the anterior esthetic zone. This research aims to provide an alternative treatment option for soft-tissue management in patients with partial edentulism in the anterior esthetic region.

Outcomes:

指标中文名:

牙槽骨尺寸和外部软组织轮廓的变化

指标类型:

主要指标

Outcome:

Changes in alveolar bone dimensions and external soft?tissue contour

Type:

Primary indicator

测量时间点:

术后4个月

测量方法:

牙槽嵴保存术后4个月测量检查缺牙间隙近远中距离及牙合龈距离,拍摄CBCT测量缺牙区牙槽嵴顶距鼻底高度、牙槽嵴顶宽度及牙槽骨密度,记录标准化口内照片。使用口内扫描仪(3 Shape)获取3D光学扫描模型。

Measure time point of outcome:

4 months after surgery

Measure method:

At 4 months after alveolar ridge preservation, measure the mesiodistal and occlusogingival dimensions of the edentulous space, acquire CBCT scans to assess the distance from the alveolar crest to the nasal floor, the crest width, and alveolar bone density, and capture standardized intraoral photographs. Intraoral scanning (3Shape) will be used to obtain a 3D optical model.

次要指标

Outcome:

Esthetic outcomes

Type:

Secondary indicator

测量时间点:

术后10天以及术后4个月

测量方法:

牙槽嵴保存术后0-14天通过视觉模拟量表(VAS)记录疼痛;在牙槽嵴保存及软组织增强术后4个月后要求患者在VAS问卷上回答“您对软组织美学效果的满意程度”。

Measure time point of outcome:

10 days and 4 months after surgery

Measure method:

Pain will be recorded using a visual analog scale (VAS) during days 0–14 after alveolar ridge preservation. At 4 months after alveolar ridge preservation and soft?tissue augmentation, patients will answer on a VAS the question: "How satisfied are you with the soft?tissue esthetic outcome?"

随机方法(请说明由何人用什么方法产生随机序列):

随机化由研究团队中的一名成员(刘长营副主任医师)执行,随机数字装在两组按顺序编号的不透明信封中,在拔牙、清理牙槽窝之后根据患者是否有骨缺损选择合适的信封以显示将使用自体结缔组织移植或胶原基质(mucograft)。

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

Randomization will be conducted by a designated team member (Associate Chief Physician Changying Liu). Random numbers will be placed in two sets of sequentially numbered, opaque, sealed envelopes. After tooth extraction and socket debridement, the envelope corresponding to the presence or absence of a bony defect will be selected, revealing allocation to either autogenous connective tissue graft or collagen matrix (Mucograft).

盲法:

The envelope method was employed throughout the study process, with participant identification numbers replacing names and medical record numbers to prevent disclosure of participant privacy during data collection, calculation, and statistical analysis. All research materials were safeguarded by Principal Investigator Gao Zhenhua, a consultant dentist, and stored on an encrypted, dedicated portable hard drive exclusively designated for this study. Upon completion of the study, all relevant research materials, data, and results were transferred to Beijing Stomatological Hospital, Capital Medical University for safekeeping. Access to participant information is restricted to authorised personnel including the investigators, the Ethics Committee, and relevant administrative departments. No other individuals possess access rights. All participant information remains stored on the encrypted portable hard drive. All research personnel have undergone rigorous confidentiality training.

Blinding:

Single-blind (participants blinded to group allocation), with outcome assessors also blinded to group assignment.
