Clinical Reports
Interim restoration using dynamic abutments to re-treat a single-implant crown with a labial angulation: A clinical report
The cause of some peri-implant problems may be primarily attributable to the design of the prosthesis. A screw-retained interim implant may be advisable for reversibility and to avoid peri-implant cement, although screw retention may be difficult for maxillary anterior implants with a labial angulation. In the treatment described, a interim screw-retained crown was attached to a dynamic abutment with a lingual screw access hole to obtain a correctly fitting restoration.Stereophotogrammetric impression making for polyoxymethylene, milled immediate partial fixed dental prostheses
Immediate post-extraction and same-day placement of interim prostheses have increased patient acceptance of implant-supported prostheses. However, for immediate prostheses supported by multiple implants, meeting passive fit and esthetic standards is often challenging. In this clinical report, implant photogrammetry was combined with conventionally obtained digitized casts to prepare an interim, milled prosthesis from a polyoxymethylene (POM) disk, using computer-aided design and computer-aided manufacturing techniques.
