This clinical report describes an approach for improving the esthetics and extending the service life of a cement-retained implant-supported ceramic single crown by using a ceramic veneer bonded to the conservatively prepared facial surface. The restoration satisfied the patient without removing and replacing the unesthetic implant-supported ceramic crown.

The screw-retained implant-supported crown is a durable, aesthetic restoration, but debonding between the crown and abutment remains a challenge to survivability. The purpose of this work was to devise an abutment shape that can be embedded into the crown while the crown is being additively manufactured. The result was a mechanically retained, no-adhesive abutment and crown unit that is mounted to the implant fixture.

Objectives: This systematic review aimed to synthesize and critically evaluate the existing evidence on factors influencing the performance of laser-assisted retrieval of cement-retained implant-supported dental restorations from implant abutments.
Data Sources: PubMed/MEDLINE, Scopus, Embase, and Cochrane Library were searched until March 2025 without language restrictions, along with a manual search of references from relevant studies.
Study Selection: Eligible studies included original research investigating laser-assisted removal or retrieval of implant-supported prostheses from abutments, considering variables related to cements, prosthetic materials, abutments, or laser parameters.

Background: The aim of this study was to investigate the effect of abutment surface treatments (sandblasting and acid or alkali treatments) on the bonding of titanium dental implant abutments and zirconium-supported ceramic crowns with resin-reinforced glass ionomer cement.
Aim: The aim of this research was to determine the optimal surface conditioning method for titanium abutments by comparing the tensile bond strength of resin-reinforced glass ionomer cement after sandblasting, acid etching, and alkali treatment.
Methods: Seventy-six dental implant abutments (AnyOne; MegaGen Co.
