目前骨内种植体在各种临床应用中都取得了令人满意的效果,然而缺牙部位常因牙槽骨高度和宽度不足不能满足种植体植入需要,作者对此进行了研究。 材料和方法 本研究分两组,A组23例个别上前牙缺失者牙槽嵴高、宽度均不足;B组4例需拔除一颗上前牙。术前对缺牙区及供体部位进行临床及X线检查,并制作外科模型。所有患者均在局麻下进行手术,A组从腭侧将缺牙区粘膜切开,唇侧近、远中行松弛切
At present, intraosseous implants have achieved satisfactory results in various clinical applications. However, the lack of alveolar bone height and width due to insufficient alveolar bone can not meet the implant implant needs, the authors studied. MATERIALS AND METHODS The study was divided into two groups. The alveolar ridge height and width of 23 cases of upper anterior teeth defect in group A were not enough. In group B, anterior teeth were removed in 4 cases. Preoperative edentulous area and donor site for clinical and X-ray examination, and the production of surgical models. All patients were under local anesthesia surgery, A group from the palatal mucosa of the edentulous area, near the labial side, far from the line of relaxation
