An alternative method for the fabrication of customised abutments for single tooth replacements. A clinical follow-up after 18 months.
The present paper describes an alternative method (The Cresco ST-method) for the fabrication of customised abutments designated for implant supported single-tooth (ST) replacements. The method is based on the conventional lost wax technology. 29 ST-replacements/crowns fabricated according to the method were tested/evaluated clinically during an 18 months period. The test was focused on mechanical complications. All crowns were supported by Cresco solid screw implants. Only one mechanical complication (retention screw loosening) was reported during the observation period. Based on the results it was concluded that the Cresco ST-method for fabrication of customised abutments is accurate and reliable. The influence of the interlocking features between implant and abutment and the advantages with customised abutments were discussed.
