This article describes the orthodontic treatment for a young woman, aged 23 years 5 months, with a Class III malocclusion and a deviated midline. Two orthodontic mini-implants (C-implants, CIMPLANT Company, Seoul, Korea) were placed in the interdental spaces between the mandibular second premolars and first molars. The treatment plan consisted of distalizing the mandibular dentition asymmetrically and creating space for en-masse retraction of the mandibular anterior teeth. C-implants were placed to provide anchorage for Class I intra-arch elastics. The head design of the C-implant minimizes gingival irritation during orthodontic treatment. Sliding jigs were applied buccally for distalization of the mandibular posterior teeth. The active treatment period was 18 months. Normal overbite and overjet were obtained, and facial balance was improved.

Just as all the flower children in the 1960’s protested the Vietnam War with the song “Where Have All The Flowers Gone” we at CPAI protest the near universal belief that the recovery, which began in December 2001, is on track and sustainable. An economically sustainable, self-operating recovery cannot occur without job creation and folks, its nowhere in sight. Oh, there will be some increases. For example over the last 5 months, 278,000 (55,600 per month), however, it takes approximately 150,000 per month to employ new entrants and at least another 150,000 to cut into the backlog of the unemployed.
