Different techniques have been proposed for cementing crown restorations to implant abutments without excess cement extruding beyond difficult-to-access restoration margins. In one approach, a copy abutment is fabricated onto which the cement-filled crown is fitted extraorally, allowing excess cement to be easily removed before intraoral transfer. This article presents a modification of this technique, wherein hot melt thermoplastic material is used for the copy abutment instead of polyvinyl siloxane. This simplifies the technique, making it faster and more reliable. It involves injecting hot melt thermoplastic material into the wetted intaglio surface of the crown, fitting a dowel pin to serve as a removal handle, filling the crown with cement, fitting it onto the copy abutment, and wiping the excess at the margins before intraoral transfer and definitive cementation.

Background: Resin cements often require substrate-specific pretreatment. Recently, universal adhesive systems have been introduced, simplifying procedures by eliminating the need for multiple adhesives and offering options that do not require light curing. This study investigated the bonding performance of universal adhesive systems combined with dual-polymerising resin cements on enamel, dentin, zirconia, lithium disilicate ceramics (LDS), and resin blocks.

Background: Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a painful disorder primarily affecting the incisor teeth of horses over 15 years of age. Clinical signs of the disease include prehension problems, halitosis and in severe cases weight loss. The disease predominately affects the reserve crown and presents as a loss of dental tissue and excessive build-up of cementum.

Background: Revision total elbow arthroplasty (rTEA) remains a technically challenging procedure with potential for substantial morbidity. Cases involving excessively long cement mantles, removal of well-fixed implants or infected revisions requiring complete cement removal introduce additional technical challenges. Our purpose was to describe the outcomes, results, and complications associated with the use of cortical windows in rTEA.

The aim of this study was to assess the effect of a chlorhexidine digluconate solution (CHX) applied as an antiproteolytic agent for controlling erosive tooth wear or as part of the adhesive treatment on long-term bond strength to eroded dentin. Dentin specimens were abraded with a 600-grit silicon carbide (SiC) paper for 1 min (sound dentin - S), subsequently treated with 2% CHX for 1 min (with excess removed, followed by a 6-hour rest), and eroded by exposure to Coca-Cola for 5 min, three times a day, for 5 days (CHX-treated and eroded dentin - CHXE), or only eroded (eroded dentin - E). The specimens were acid-etched (15 s), rinsed (30 s), dried (15 s), and rehydrated with 1.

Background: Crown cementation is a common technique for implant-supported prosthodontics. However, for possible slipping of the cement below the mucosal margin, its thorough removal poses some issues. The objective of this study was to evaluate the presence of submucosal cement residues in patients with peri-implant disease by endoscopic visualization and to investigate the potential correlation between the pathological scenario and the spatial position of cement residues.
