The angulation and the position change of the planned implant after tomographic imaging / 대한구강악안면방사선학회지

ABSTRACT

PURPOSE: To measure the differences of the splint pin angulation and the position of the planned implant site after conventional tomographic analysis. MATERIALS AND METHODS: The angulation and the location of the metal splint pin retained in acrylic stent were compared with the corrected angulation and the location of the implant fixture on the 331 tomographic images. RESULTS: The stent pins were located buccal in 40%, lingual in 10% to the corrected implant site after analysis of the conventional tomographic image. The angle and the location of the maxillary splint pin were mainly directed buccal on incisor and canine regions. The angle and the location of the splint pins in premolar and molar regions needed less corrections in both maxilla and mandible. CONCLUSIONS: This study demonstrated that the use of tomographs was essential for successful dental implant planning.
