A case of hyperodontia with twenty-two supernumeraries: its surgical-orthodontic treatment.
A 10.1-year-old boy showed no permanent teeth, with the exception of the lower central incisors. An x-ray examination revealed that eruption of the permanent dentition was obstructed by 1 deciduous supernumerary and 22 permanent supernumeraries ectopically. Treatment consisted of the following steps: (1) extracting all deciduous and supernumerary teeth; (2) waiting for the roots of the permanent teeth to develop and fitting two temporary partial prostheses; (3) assisting eruption of the permanent teeth by removing the bone that covers the remaining teeth and applying crowns to stimulate the eruption; and (4) bringing the permanent teeth into occlusion with orthodontic treatment. The problem of limiting treatment time was made more difficult by the amount of repositioning needed to bring the teeth into occlusion and by delayed root formation. Therefore the orthodontist decided to use extreme caution in applying forces; as a result, treatment time was lengthened. Success was due to good teamwork between the surgeon with an orthodontic background and the orthodontist, who was familiar with surgical procedures.
