Evaluation of the peri-implant tissues in the esthetic zone with prefabricated titanium or zirconia abutments: A randomized controlled clinical trial with a minimum follow-up of 7 years.

Statement Of Problem: Long-term clinical studies are lacking on the influence of the type of abutment, titanium or zirconia, on peri-implant tissues.

Purpose: The purpose of this randomized clinical trial was to evaluate peri-implant tissues with titanium or zirconia abutments.

Material And Methods: A total of 26 single-tooth implant-supported prostheses in 14 participants were analyzed.

Zirconia Abutment Supporting All Ceramic Crowns in the Esthetic Zone: Interim Results of a Prospective Study.

Aim: This prospective study evaluated peri-implant tissues around all-ceramic crowns fabricated using CAD/CAM technology.

Material And Methods: Twenty-five patients received pre-fabricated zirconia implant abutments with CAD/CAM zirconia copings in the esthetic zone. Implants were evaluated at baseline, and at 3 and 6 months in function.

An alternative approach for augmenting the anterior maxilla using autogenous free gingival bone graft for implant retained prosthesis.

Numerous factors may keep surgeons from placing implants in the anterior maxilla in order to avoid suboptimal restorative outcomes. This paper describes a technique of an autogenous-free gingival-bone block graft, which allows bone and gingival augmentation and a primary seal to be achieved simultaneously. Additionally, it describes a technique for achieving primary soft tissue closure of maxillary extraction sockets using a rotated pedicle palatal connective tissue flap.
