Autologous Tooth Root in Ridge Preservation

The anatomy of the alveolar bone around the teeth can be altered by tooth extraction. Bone ridge preservation can preserve/improve the quality and quantity of alveolar bone for future implants or dentures to promote predictable function and esthetics; in addition, extraction cavity closure can be used as an aid, in vertical or alveolar ridges. Horizontal preservation had significantly better clinical outcomes. According to the treatment needs, appropriate bone materials were selected for bone ridge preservation and local administration of Vit.D3, and the extraction cavity closure was performed with autologous root slices to observe and track the therapeutic effect. Free gingival grafts or pedicle soft tissue grafts can help bone and spine preservation with good clinical outcomes, but autologous soft tissue grafts can increase wounds at the donor site and increase the patient's postoperative discomfort. Collagen sponges can help bone graft materials. Stay in the extraction cavity, promote the formation and fixation of blood clots, and prevent soft tissue from growing in, but collagen degrades rapidly, and it will decompose faster once the nearby tissue has symptoms of acute inflammation. The advantage of autologous root slices is that it is biocompatible High performance, it can effectively isolate the bone graft material from the contamination of the oral environment, and it will not absorb or be infected due to the acute inflammation of the nearby tissue. Wounds can reduce postoperative discomfort, so the use of autologous tooth root slices without the periodontal ligament exposed to the oral environment is less likely to cause infection or premature absorption, and can effectively protect the stability of blood clots in the extraction cavity. , reduce the saliva contamination of bone graft materials, and at the same time will not increase the cost of materials or the economic burden of the patient, the side with the periodontal ligament can also promote bone formation and help the retention of alveolar bone, which is both novel and good. The method of sealing the extraction socket can improve the predictability and aesthetics of the bone and spine preservation surgery, and help the patient to be replanted in an ideal position in the future. It is also hoped that the effect of Vit.D3 in promoting bone regeneration can accelerate the healing of the extraction socket.
