Brief Summary:
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.
Detailed Description:
The anterior tooth region is the key area of aesthetics, which has always been the difficulty and hotspot of implant restoration. In tooth extraction caused by various diseases, the amount of new bone in the tooth extraction fossa often cannot reach the level of the original alveolar ridge, especially the damage to the lip and buccal bone plate is more serious, resulting in insufficient bone mass when the implant is implanted in the later stage. Therefore, bone increment surgery is often used to reconstruct the collapsed alveolar ridge. Among them, site preservation has been widely adopted because of its effective promotion of autologous bone regeneration, simple operation and strong operability. Site preservation is performed by bone grafting on the extraction fossa immediately after tooth extraction to preserve the height and width of the remaining alveolar ridge as much as possible, and retain the corresponding amount of soft tissue, so as to provide sufficient bone mass for later implantation surgery and repair, so as to obtain good aesthetic repair effects.
However, there is currently a lack of oral biofilm that can be opened for healing. After filling bone meal and covering barrier biofilm, the mucosal tissue needs to be fully reduced and then tightly sutured. Sufficient reduction of gingival soft tissue in the aesthetic area of the anterior teeth will undoubtedly increase the surgical wound, and obvious scars will appear in the early stage of repair, seriously affecting the aesthetic appearance. Therefore, in order to simplify the surgical plan of site preservation, reduce trauma, and obtain stable bone growth and good soft tissue morphology, this project proposed to use oral repair membrane with open healing to replace the commonly used clinical collagen membrane for site preservation of the aesthetic area of the anterior teeth.
