Implant and Provisional Crown Placement

Implant Dentistry, 1998
Most endosseous implant systems are placed using a two-stage surgical procedure. The surgical stages are separated by a period of 4 to 6 months to allow osseointegration. At Stage-I surgery, the implant is fixed in bone and submerged under mucosa, while at Stage-II surgery, the implant is exposed and the transmucosal abutment is connected to the ...

Chairside provisional implant crown construction: a clinical technique

Dental Update, 2022
Provisional restorations provide numerous advantages during dental implant treatment including manipulation of the peri-implant soft tissue contour to optimise the aesthetic outcome. Chairside construction expedites this stage of the treatment to a single visit for the benefit and convenience of both the dental practitioner and patient.

In-Vitro Marginal Fit of 3D-Printed vs Milled Provisional Crowns

Journal of Pioneering Medical Sciences
Context: Provisional crowns are essential intermediate restorations in fixed prosthodontics, and marginal fit is a key determinant of periodontal health, pulpal protection, and long-term clinical success. Present CAD/CAM technologies allow for production

A safe technique for removal of provisionally cemented crowns

Journal of Endodontics, 1993
A technique is presented for removing full-cast crowns and porcelain crowns that have been temporarily or provisionally cemented. A rubber dam retainer clamp with rubber dam attached is placed on the crown and clamped near its margins. Steiglitz forceps are used to apply pressure and leverage. The assembled unit is removed with the Steiglitz and safely

Colour stability of provisional crown and bridge restoration materials

British Dental Journal, 1998
In an in vitro study to determine the colour stability of provisional restoration materials, the PMMA synthetics Trimm and Cronsin and the bis-acrylic composites Protemp Garant, Protemp Garant NF, Protemp II and Provipont DC were investigated.The colour changes of the cylindrical untreated samples were measured in comparison with samples after 24 and ...

Novel Antibacterial Resin Coating for Dental Provisional Crowns to Suppress Biofilms and Inhibit Secondary Caries

Coatings
Provisional crowns are often used in dentistry for prolonged periods, but bacterial attachment and dental plaque often lead to gingival inflammation and secondary caries.

Crown retention and flexural strength of eight provisional cements

The Journal of Prosthetic Dentistry, 2007
Few studies have compared the retention of resin-based and zinc-oxide noneugenol provisional cements. Crown retention testing is difficult and variable; therefore, a simpler method of testing by using flexural strength is indicated.The purpose of this study was to measure the retention of base metal alloy castings to dentin provided by 8 provisional ...
