Gingival esthetic outcome around a bone-level implant--a case report.

The objective of this case report is to review the clinical thinking, decision making, and actions of the authors, from the time of the first patient visit to the final esthetic outcome. Initial uncertainty led the authors to perform procedures that were believed to provide best outcomes or alternatives for further procedures, if necessary. An optimal final esthetic outcome was the goal, and the short-term (one-year) esthetic results are presented.

Measurement of the rotational misfit and implant-abutment gap of all-ceramic abutments.

Purpose: The specific aims of this study were to measure the implant and abutment hexagonal dimensions, to measure the rotational misfit between implant and abutments, and to correlate the dimension of the gap present between the abutment and implant hexagons with the rotational misfit of 5 abutment-implant combinations from 2 manufacturers.

Materials And Methods: Twenty new externally hexed implants (n = 10 for Nobel Biocare; n = 10 for Biomet/3i) and 50 new abutments were used (n = 10; Procera Zirconia; Procera Alumina; Esthetic Ceramic Abutment; ZiReal; and GingiHue post ZR Zero Rotation abutments). The mating surfaces of all implants and abutments were imaged with a scanning electron microscope before and after rotational misfit measurements.
