Chair-side procedure for connecting transpalatal arches with palatal implants

The present investigation examined a chair-side procedure for connecting a transpalatal arch (TPA) with palatal implants, which does not involve any laboratory work. This new technique was compared with the standard procedure in terms of the number of steps, the time required, and the cost. The total chair-side time needed with the standard procedure was 38 minutes, with the material costs amounting to e159.6. With the chair-side procedure the total time required was 55 minutes, and the cost of the material totalled e34.1. The chair-side procedure was derived from orthodontic treatment concepts and is independent of laboratory input. Its major advantage is that it does not require transfers, which necessitate additional steps. These steps, which are inevitable with the standard procedure, resulted in an unexpectedly high cost level and increased the total cost. The difference in the cost of the material between the two procedures amounted to e125.5 and timewise the difference was 17 minutes. Whilst TPA-implant connections can be made with both the standard and chair-side procedures, the standard procedure, although taking considerably less chair-side time, was four times more expensive than the chair-side procedure.
