About this trial
In this study, an open healing oral restoration membrane was used for site preservation in the esthetic area after tooth extraction to maintain the space for tooth extraction and bone formation. Clinical observation and cone-beam computed tomography (CBCT) were used to comprehensively evaluate the effect of this operation on promoting the growth of soft and hard tissues, and to provide a new treatment method for site preservation in the esthetic area of clinical anterior teeth.

Treatments tested in this trial
site preservation surgery with open healing
Procedure/SurgeryTooth extraction in the aesthetic area of the anterior teeth without the expansion and flap were reduced in the operative area. Site preservation surgery was perfomed using Bio-oss (0.5g, Small granule) and Yinlife PCL membrane (25\*25mm size) , with opened wound.
site preservation surgery with close sutures
Procedure/SurgeryTooth extraction in the aesthetic area of the anterior teeth with the expansion and flap were reduced in the operative area. Site preservation surgery was performed using Bio-oss (0.5g, Small granule) and bio-gide (25\*25mm size) . The gums were closely drawn and sutured.

Trial outcomes
Primary outcomes
soft tissue healing efficiency
After calibrating the magnification ratio of the tooth extraction wound photos, the reduction ratio of the tooth extraction wound area at 7 days, 14 days, 1 month, and 3 months after surgery was calculated based on the immediate postoperative tooth extraction wound photos to evaluate the soft tissue healing efficiency.
Secondary outcomes
Bone healing efficiency
NNT Viewer software was used to calibrate CBCT images before and 3 months after surgery. The same section position was used to extract anterior teeth. The area marked by periodontal ligament outside the root before surgery was used as the extraction socket area, and the black corresponding to the blank in the postoperative image was used to represent the unhealed extraction socket. It was used to evaluate the healing efficiency of bone tissue.
