Clinical Application of the Anterior Maxilla Atraumatic Immediate Implant by Cone Beam Computer Tomography

Abstract

This paper is aimed to investigate the value of using con-beam computer tomography(CBCT)to evaluate bone volume and labial bone wall integrity in the anterior maxillar,and guide atraumatic immediate implant.Thirty patients who planed to receive atraumatic immediate implant in the anterior maxillar under-went CBCT scan. After analysis of 6 patients with 8 tooth labial bone wall intact, alveolar crest width is greater than 5mm, less than or equal 7mm, which suitable for atraumatic immediate implant and bone defects not filling,while 14 patients 20 tooth labial bone wall intact, alveolar crest width is greater than 7mm, which suitable for atraumatic immediate implant and bone defects need to be filled by bio-oss collagen. 10 patients 14 tooth labial bone wall defects or bone buried teeth, which did not suitable for atraumatic immediate implant and excluded in this study.The treatment outcomes were Assessed postoperatively.According to the results of 20 patients with 28 tooth completed the atraumatic immediate implant, 14 patients 20 bone defects were filled by bio-oss collagen.CBCT detected the value of anterior maxillary alveolar bone and alveolar bone measured value is consistent. The research shows that CBCT imaging plays an important role in determining bone quality and evaluating labial bone wall integrity in anterior maxillar and guiding atraumatic immediate implant.
