Esthetic Evaluation of Anterior Single-Tooth Implants with Different Abutment Designs-Patients' Satisfaction Compared to Dentists' Observations.

Purpose: To correlate patients' satisfaction and dentists' observations regarding two abutment designs used for single crowns in the esthetic zone: a divergent one (control) and a curved one (experimental), with special emphasis on muco-gingival esthetics.

Materials And Methods: Twenty-six patients with nonadjacent missing teeth in the esthetic zone were enrolled in a randomized clinical trial (within-subject comparison). Two implants placed in each were restored using abutments of different geometry.

Papillary fill response in single-tooth implants using abutments of different geometry.

Objective: To evaluate the influence of abutment geometry on papillary fill in the esthetic zone in a delayed crown protocol.

Materials And Methods: Twenty-six subjects received two non-adjacent endosseous implants in the esthetic zone. Functional temporary crowns were installed 17-19 weeks later, using conventional (control) and curved (experimental) abutments.

Comparison of two different abutment designs on marginal bone loss and soft tissue development.

Purpose: To assess the response of soft tissues around two different abutment designs in healed sites in the esthetic zone.

Materials And Methods: Twenty-six subjects received two endosseous implants in healed, bilateral implant sites in the esthetic zone in the maxilla or the mandible. After 17 to 19 weeks and left/right randomization, the implants were restored with either a conventional (control) or curved (experimental) titanium abutment and a provisional crown.

An exploratory study on assessment of gingival biotype and crown dimensions as predictors for implant esthetics comparing caucasian and Indian subjects.

Gingival biotype and crown dimensions may be important predictors for the esthetic outcome of surgical procedures. However, the visual distinction between "thick" and "thin" biotype may not be a suitable predictive parameter of surgical outcome. Intraoral photographs of 73 Indian and Dutch subjects were matched with respect to age and gender and were used to determine the gingival biotype (subjective assessment) and crown dimensions (objective assessment).

A comparative study to evaluate the effect of two different abutment designs on soft tissue healing and stability of mucosal margins.

Aim: To evaluate the effect of two different abutment designs on soft tissue healing and the stability of the mucosal margin in vivo.

Materials And Methods: Twenty-nine subjects received two, non-adjacent endosseous implants in the esthetic zone. Subsequently, conventional (control) and curved abutments (experimental) were placed in combination with a temporary restoration (left-right randomization).
