Dimensional Changes of the Peri‐Implant Mucosa Applying a Suture‐Free Wound Closure Using a Healing Abutment Attachment: A Randomised Controlled Clinical Trial

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To compare peri‐implant soft‐tissue dimensional changes following wound closure using a suture‐free healing abutment attachment (HAA) compared to conventional suturing during implant surgery. Materials and Methods Thirty patients who were randomly allocated to the HAA group (15 patients, 20 implants) or the suture group (15 patients, 15 ...

Comparison of Aesthetic, Mechanical Outcome, and Bone Loss in Angulated Screw Channels (ASCs) and Cement-Retained Implant-Supported Prosthesis: A Case-Control Study

Dentistry Journal
Angulated-screw channels (ASCs) allow the clinician to employ screw-retained restorations in almost all cases, as the access hole can be moved away from the vestibular portion of the crown, where it would jeopardize the final esthetic result.
