FIELD: medicine. ^ SUBSTANCE: method involves preparing teeth to be splinted for setting crown and manufacturing permanent splint on crowns for fixing loose teeth and exchanging included defects of the frontal row, fixing splint on steady teeth. Non-removable splint on crowns is manufactured from metalloceramics and the splint is fixed on steady teeth adjacent to the last teeth taken into splinting, using orthodontic wire (flex-arc). To do it, grove is modeled for placing the splinting orthodontic flex-arc wire concurrently with modeling crown unit. The groove is produced with wire retention being allowed. The groove is not covered with ceramics. The finished is fitted and then, the orthodontic flex-arc wire is placed into the groove and fixed with glue. Orthodontic wire ends are left projecting. Groove equal in length to projecting wire portion length is produced on steady teeth adjacent to the last teeth taken into splinting at the same level with the crown unit groove. The splint is fixed with cement. The groove is closed with composite material. The projecting orthodontic flex-arc wire portion is built-in also with composite material into the grooves produced in the steady teeth adjacent to the grooves in the last teeth taken into splinting. Correction, abrasion and polishing are carried out near each tooth belonging to group under splinting with following composite polymerization. ^ EFFECT: wide range of functional applications; improved physiologic results. ^ 3 cl, 2 dwg |
