Application of CAD-CAM for Fabrication of Metal-Free Band and Loop Space Maintainer

摘要

An ideal occlusion with proper tooth alignment and fully functional teeth is the ultimate goal of all dental treatments. Premature extraction of deciduous teeth is a common sequeale of untreated dental caries in teeth in which the damage is far beyond repair. Premature extraction might lead to loss of space for the successor tooth, drifting of teeth and loss of arch integrity leading to malocclusion in the permanent teeth. To prevent the space loss, space maintainers are designed and delivered at the time of extraction to allow for development of proper functional occlusion in children till the eruption of the succedaneous permanent tooth. A six-year-old female patient with chronic intra-radicular abscess in upper right first primary molar was treated with extraction followed by the placement of BruxZir zirconia space maintainer. Clinical and radiographic examinations were performed at one and six months. At the end of six months, the patient was completely asymptomatic and there were no visible signs of gingival inflammation and tissue irritation at the site of the space maintainer.
