“…The average study length was about 6 years. Additional studies 33,[154][155][156][157][158][159][160][161] have been published with clinical data about post and core complications, but they did not present the total number of complications encountered, or they only presented data regarding 1 or 2 types of complications. One study 162 performed a meta-analysis of available studies, and 1 study 163 developed a mechanical longevity estimation model.…”

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...

“…[1][2][3][4] In a 5-year follow-up study of non-surgical endodontically treated teeth, a root fracture was an adverse event in 32.1% of cases, for which the elected treatment was extraction. 5 Thus, VRF of endodontically treated teeth appears to be clinically significant.…”

“…5 Thus, VRF of endodontically treated teeth appears to be clinically significant. 1 Pain and swelling, the presence of an isolated deep periodontal pocket and a combination of periapical and lateral radiolucency associated with the root are considered pathognomonic for VRFs. 6 However, the clinical signs, symptoms and radiographic appearance of VRFs frequently resemble endodontic failure or periodontal disease.…”

Objectives: The purpose of this study was to evaluate the accuracy of diagnosing vertical root fractures (VRFs) by comparing the volume of bone defects in VRFs with those in nonVRFs on reconstructed three-dimensional (3D) models (TDMs) using CBCT. Methods: 32 maxillary pre-molars and anterior teeth with radiolucent areas were evaluated on pre-operative CBCT images. Of the 32 teeth, 16 had a fractured root (VRF group) and 16 had a non-fractured root (non-VRF group). The radiolucent area of each tooth was traced in each dimension [mesiodistal, buccolingual and horizontal (the apicoincisal aspect)] by two observers, and 3D images were reconstructed with the Amira ® software (Visage Imaging Inc., Richmond, Australia). The volume, V, of the TDM was divided into the coronal side and the periapical side at the horizontal slice through the apical foramen, and v was defined as the volume of the coronal side. The values of v/V were calculated for all cases. The Mann-Whitney U test was used to compare values between the VRF group and the non-VRF group (p , 0.05). A receiver operating characteristic (ROC) curve was constructed to select the optimal cut-point. Results: There was a statistically significant difference in the value of v/V between the two groups (p , 0.05). With a cut-point derived from the ROC curve, and the sensitivity, specificity and accuracy of predicting the VRFs were 1.00, 0.75 and 0.88, respectively. Conclusions: Lesions resulting from VRFs can be distinguished from those of non-VRFs on 3D CBCT images with a high degree of accuracy, based on their different 3D shapes.

“…Vertical root fractures (VRFs) of endodontic treatment teeth are often encountered in the dental retreatment [1]. Clinical diagnosis of VRFs is difficult because in only a few cases can the presence of a fracture line be detected correctly with radiographic or oral examination.…”
