牙列缺损
胶原基质(Mucograft)代替自体结缔组织移植用于前牙美学区牙槽嵴保存的软组织管理效果非劣效性研究
胶原基质(Mucograft)代替自体结缔组织移植用于前牙美学区牙槽嵴保存的软组织管理效果临床对照研究
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。
随机平行对照
其它
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)。
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.
