An old patient wearing complete dentures during 35 years, with severe atrophied bone, suffered from poor retention, instability and
insufficient chewing of dentures. At first, maxilla was restored with new complete denture for regain of vertical dimension and 4 years
later, mandible was planned with mini-implant-retained overdenture. Mini-implants of mandible were early loaded and fabrication procedure
was compressed simply with closed mouth impression technique. Without any inconvenience of patient, chief complaint such
as numbness of mandible and insufficiency of mastication was disappeared. Although risk of mandible fracture should be considered
during follow-up period, mini-implant on the atrophied mandible was considered simple modality for successful function. (JOURNAL
