“…A poorer adaptation refers to a greater gap between the FDPs and the abutment, and is associated with a sharp decline in the FDPs life owing to the higher incidence of secondary caries resulting from the invasion of pathogens from saliva or food 7) . Previous studies regarding the adaptation of FDPs fabricated by the SLA method have thus far been very limited 5) .…”

“…These methods make the manufacture of FDPs using metallic materials such as alloys much easier; however, information regarding the quality of the resulting prosthesis is still limited. Although many factors influence the quality of FDPs, the most important is the gap between the prosthesis and tooth forms or tooth preparations [6][7][8] . A few authors have previously reported assessments of the gap in FDPs manufactured using the SLS method [9][10][11] ; however, similar reports on the gap of FDPs fabricated using the Fig.…”

The purpose of this study was to investigate, by measuring the gap, the possible clinical use of three-unit fixed dental prostheses (FDPs) manufactured using stereolithography. A total of 20 epoxy models were built with a same case (abutment teeth 14, 16). The 40 specimens were produced using the stereolithography (SLA) and wax-up (LW). The 960 gaps of the 40 specimens produced were measured by a silicone replica. The Wilcoxon rank sum test was then used to compare and analyze the data obtained from the two groups (α=0.05). The total gap, as measured from the SLA and LW groups, was 98.6 and 66.6 µm, respectively. The results indicate that the gap in the SLA group is statistically significantly greater than that in the LW group (p<0.05). Further assessment and improvement of the SLA method for the fabrication of FDPs is evidently still required.

“…The length of the 19 studies ranged from 1 year to 20 years, with an average length of about 8 years. There were other studies 16,17,[36][37][38][39][40][41][42][43][44] containing data that were not included in this publication. One article 36 presented information about fixed partial dentures by calculating survival rates with the Kaplan-Meier method.…”

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...

“…Walton et al, 10 Foster, 41 and Valderhaug 23 came to similar conclusions, namely that the mean life span with caries as the reason for failure was between 8.4 and 12 years, while for loss of retention, the mean life span was between 4.5 and 9 years. In the present study, the mean life span with caries as the reason for failure was 10.9 years, while for loss of retention, the mean life span was 6.1 years.…”

Purpose: This study evaluated treatment outcomes of 4-unit porcelain-fused-to-gold fixed dental prostheses (FDPs) replacing 2 adjacent missing teeth. Materials and Methods: A total of 102 FDPs made in an undergraduate university clinic for 73 patients were evaluated for up to 20 years, with a mean survival follow-up time of 11.4 years. All patients were offered an oral health maintenance program. Treatment failures were divided into irreversible (loss of FDPs/finish line involved) or reversible (FDPs and finish line intact after conservative treatment) complications and into biologic and technical/patient-related failures. Results: The Kaplan-Meier overall estimated survival rate was 68.3% at year 20. There was a statistically significant difference (P = .007) between the survival rates in the maxilla for the vital group (73.8%) and those for the root canal-treated group (25.1%). Comparing the survival rate in the root canal-treated group for the restorations in the maxilla (25.1%) versus the mandible (66.8%), a statistically significant difference (P = .011) was found. The main reason for irreversible failure was caries (32.0%). Conclusion: The estimated successful outcome of 4-unit FDPs over an up to 20-year period is considered favorable and should be compared with the survival rates of other treatment options for the replacement of 2 adjacent teeth. Occurrence of a previously reversible complication appears to be a predictive factor for an irreversible complication later on. A reversible complication within the first 2 years will lead to an early irreversible complication. Int J Prosthodont 2008;21:259-266.
