Abstract
Recently, less invasive treatment has been focused based on the patient driven concept in implant treatment. A narrow diameter implant is one of the alternatives to reduce the pain of patients, and it enables to avoid bone augmentation and to shorten treatment period, and makes treatment procedure easy. However, narrow diameter implants have been used in limited case by its physical properties, and its application for full mouth reconstruction is considered to be difficult. Furthermore, it is also difficult to achieve good esthetic outcome in prosthetic treatment by using them. Therefore, in cases where bone width is narrow, regular diameter implants is frequently used with bone augmentation,which is invasive and increase the treatment period and costs. On the other hand, it has been reported that narrow diameter implants showed similar clinical outcome compared with regular diameter implants recently. In this case, we used narrow diameter implants to full mouth reconstruction of no opposing tooth occlusion without bone augmentation to reduce patient tolerance, and had a good clinical outcome. We concluded that the use of narrow diameter implant appears to be predictable if understanding of the properties of narrow implant and careful and appropriate planning are provided. In addition,CT image and three dimensional bone model is useful for application of narrow diameter implant.
