The purpose of the study was to evaluate, by examination of periapical radiographs, whether the application of intra-radicular posts in endodontically treated teeth can lead to the development of periapical lesions. A total of 103 panoramic radiographs from 103 patients (263 endodontically treated teeth) from Faculty of Dental Medicine, University of Varna, Bulgaria were investigated. From the 263 teeth evaluated, 58 (22%) had intra-radicular posts. While examining the radiographs a predetermined set of radiographic criteria was included: all teeth should be endodontically treated and have coronal restorations, the intra-radicular posts should be metal cast posts. The success rate for all endodontically treated teeth (n=58) was 70,7%. The following results show that using intra-radicular posts for restoration of endodontically treated teeth do not lead to periapical lesions in the practice where most of the patients were treated. It is most important to perform the coronal restorations carefully in order to avoid coronal microleakage

“…Intraoral loads vary widely and have been reported to range from 10 to 431 N 4) . Nonetheless, all the studies clearly showed that oblique loads generate more stress than loads directed along the long axis of the tooth [23][24][25] . In the current study, an oblique loading of 200 N was applied to the central fossa, distal marginal ridge, mesiobuccal cusp tip, and distobuccal cusp tip.…”

To reduce loss of tooth tissue and to improve esthetic results, inlay and onlay restorations are good treatment choices for extensive cavities in posterior teeth. The aim of this paper was to evaluate, by means of three-dimensional finite element analysis, the effects of restorative material and cavity design on stress distribution in the tooth structures and restorative materials. Two different nanofilled composites and two different all-ceramic materials were used in this study. A permanent molar tooth was modeled with enamel and dentin structures. 3-D inlay and onlay cavity designs were created. Von Mises, compressive, and tensile stresses on the restorative materials, core materials, enamel, and dentin were evaluated separately. On the effect of restorative material, results showed that in the case of materials with low elastic moduli, more stress was transferred to the tooth structures. Therefore, compared to the nanofilled composites, the all-ceramic inlay and onlay materials tested transferred less stress to the tooth structures. On the effect of cavity design, the onlay design was more efficacious in protecting the tooth structures than the inlay design.

“…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%.…”

“…One study 162 performed a meta-analysis of available studies, and 1 study 163 developed a mechanical longevity estimation model. Three studies 16,146,150 evaluated the posts and cores for periods between 1 to 4 years and recorded a mean complications incidence of 11%. One of the 3 studies 146 indicated the posts were observed over periods from 2 to 10 years.…”

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...
