Vol. 13 – Number 50 – 2022 PITEAM COLUMN Page 32-40 Use of CAD/CAM technology for production of titanium customized abutment and zirconia crown on implant Rander Moreira Macedo¹ Bruno Fernando Candido¹ Carlos Eduardo Edwards Rezende¹ Flavia Sukekava¹ Paula Porto Spada¹ Luiz Carlos Carmo Filho¹ Abstract The rehabilitation of missing teeth with dental implants is consolidated even in aesthetic areas. The knowledge of the professional, combined with new technologies such as CAD/CAM, as well as materials with good mechanical, biological, and aesthetic properties are important to obtain success at the end of treatment. The aim of the present study was demonstrated the clinical sequence of treatment for a cemented retained prosthesis on customized titanium implant abutment milled by CAD/CAM technology. A 59-year- old male patient was referred to a private practice due to the absence of tooth 13. A BL 3,3 x 10 mm implant (Straumann – Switzerland) was placed and bone regeneration performed in the area simultaneously. After eight weeks, the implant was exposed, and a temporary crown made. Gingival conditioning was performed in the following sessions and, then, the impression was taken with a customized impression post. The casts were scanned and a customized titanium abutment following the gingival profile was virtually designed and later on milled using CAD/CAM technology. A zirconia coping received the same workflow, which has later received an esthetic layer of ceramic. Clinically the abutment was screwed, the crown received minor adjustments and it was cemented. It was concluded that the use of a customized implant abutment in titanium and a zirconia crown fabricated by CAD/CAM technology may be a clinically feasible treatment option for cemented retained prosthesis in anterior maxilla.
