“…Eleven studies 16,[144][145][146][147][148][150][151][152]155,161 provided numerical data related to post loosening. A total of 135 of 2596 posts loosened from the root for a mean incidence of 5% (range of 0% to 10%).…”

“…There are 12 clinical studies 16,[143][144][145][146][147][148][149][150][151][152][153] that report the total number of posts and cores evaluated and the total number of complications encountered. There were 279 complications found among the 2784 posts and cores in the 12 studies, producing a mean complications incidence of 10%.…”

“…Because a mean observation time was not disclosed, a decision was made to include this data with the 1-to 4-year studies. Nine studies [143][144][145][147][148][149][151][152][153] evaluated the posts over periods between 5 and 10 years, with a mean complications incidence of 10%. One study 145 evaluated posts over 1 to 25 years, and there also was no information about the average observation time.…”

The purpose of this article is to identify the incidence of complications and the most common complications associated with single crowns, fixed partial dentures, all-ceramic crowns, resin-bonded prostheses, and posts and cores. A Medline and an extensive hand search were performed on English-language publications covering the last 50 years. The searches focused on publications that contained clinical data regarding success/failure/complications. Within each type of prosthesis, raw data were combined from multiple studies and mean values calculated to determine what trends were noted in the studies. The lowest incidence of clinical complications was associated with all-ceramic crowns (8%). Posts and cores (10%) and conventional single crowns (11%) had comparable clinical complications incidences. Resin-bonded prostheses (26%) and conventional fixed partial dentures (27%) were found to have comparable clinical complications incidences. The 3 most common complications encountered with all-ceramic crowns were crown fracture (7%), loss of retention (2%), and need for endodontic treatment (1%). The 3 most common complications associated with posts and cores were post loosening (5%), root fracture (3%), and caries (2%). With single crowns, the 3 most common complications were need for endodontic treatment (3%), porcelain veneer fracture (3%), and loss of retention (2%). When fixed partial denture studies were reviewed, the 3 most commonly reported complications were caries (18% of abutments), need for endodontic treatment (11% of abutments), and loss of retention (7% of prostheses). The 3 most common complications associated with resin-bonded prostheses were prosthesis debonding (21%), tooth discoloration (18%), and caries (7%). (J Prosthet Dent 2003;90:31-41.) A complication has been defined 1 as "a secondary disease or condition developing in the course of a primary disease or condition." Although complications may be an indication that clinical failure has occurred, this is not typically the case. It is also possible that complications may reflect substandard care. But once again, this is usually not true. Most of the time, complications are conditions that occur during or after appropriately performed fixed prosthodontic treatment procedures.Knowledge regarding the clinical complications that can occur in fixed prosthodontics enhances the clinician's ability to complete a thorough diagnosis, develop the most appropriate treatment plan, communicate realistic expectations to patients, and plan the time intervals needed for post-treatment care. Although a plethora of articles present clinical complications data, none provide a comprehensive comparison of the complications associated with the most commonly used restorations/ prostheses.One of the purposes of this article is to present data regarding the incidence of clinical complications associated with the following restorations/prostheses: single crowns (all-metal, metal ceramic, resin veneered metal); fixed partial dentures (all-metal, metal ceramic, resinvenee...

“…Morgano SM, Heydeche G, Mentin AG quoted custom-fabricated, cast post and cores are still regarded as the established technique or gold standard for restoring extensively damaged teeth. [10][11][12] The presence of a split for the post system reduces insertion and cementation stresses for this post system. The split may act as a vent for release of hydrostatic pressure during cementation of the post into the canal and minimizes stresses during cementation.…”

Split Cast Metal Post and Core

The best plan for success is to begin with the end in mind. It generally is agreed that the successful treatment of a badly broken down tooth with pulpal disease depends not only good endodontic therapy, but also on good prosthetic reconstruction of the tooth after endodontic therapy. The primary purpose of the post is to retain a core that can be used to retain definitive prostheses. A post and core help prevent coronal fractures when the remaining coronal structure is very thin after tooth preparation. When a substantial amount of coronal structure is lost a cast post and core is indicated. In this clinical report the root canal treated left mandibular first molar is restored with split cast metal post and core design using the direct technique for the fabrication of the post and core pattern using the autopolymerizing acrylic resin material and then further casted in the laboratory using the base metal alloy.

“…One such investigation has reported an 82% success rate in 516 anterior teeth restored with metallic posts for an observation period of over 10 years. 5 Another investigation has described a 2.1% failure per annum for 788 teeth restored with metal posts during a fi ve year period, 6 while another long-term study has reported nine failures amongst 138 teeth restored with cast post and cores. 7 The most common modes of failure associated with metal posts include loss of retention, root fracture or post fracture.…”
