“…Huda et al 50 stated that endocrowns had better fracture resistance than inlay and onlay restorations. The authors compared the fracture resistance of various Cerasmart inlays, onlays, and endocrown restorations in endodontically treated mandibular molars.…”

“…Although many studies have investigated the load bearing effect of FRCs under composite restorations of ETTs, only a limited number of studies have investigated the effect of FRCs under CAD/CAM materials. [48][49][50][51] Rocca et al 51 compared the fracture resistance and fracture pattern of endodontically treated molars restored with resin nanoceramic CAD/CAM material (Lava Ultimate) either with an endocrown without fiber reinforcement or overlays with different types of fiber reinforced cavities. It was found that reinforcement did not improve fracture resistance, and all samples fractured under the CEJ in a nonrepairable manner.…”

Objective: The aim of this study was to investigate the effects of fiber-reinforced composite base material on fracture resistance and fracture pattern of endodontically treated maxillary premolars restored with endocrowns using two different resin nanoceramic computer-aided design and computer-aided manufacturing (CAD/CAM) restorative material. Methods: Forty extracted sound maxillary premolars with an occlusal reduction of 2 mm above the cementoenamel junction (CEJ) was performed following root canal treatment. Mesial interproximal box was prepared for each tooth at the margin of the CEJ and randomly distributed into four groups ( n = 10) as follows: Group A, no resin build-up in the pulp chamber; Group B, 2 mm of fiber-reinforced composite (FRC) build-up (EverX Posterior, GC).; Group C, no resin build-up in pulp chamber; Group D, 2 mm of FRC build-up. Groups A and B were prepared with resin nanoceramic (RNC) consisting ceramic nanofillers (Lava Ultimate 3 M ESPE), while Group C and D were prepared with RNC consisting ceramic nanohybrid fillers (Cerasmart GC Corp). All samples were subjected to 1,200,000 chewing cycles (1.6 Hz, 50 N) and 5000 thermal cycles (5°C–55°C) for artificial aging on a chewing simulator with thermal cycles (CSTC). Samples that survived the CSTC test without being damaged were subjected to a load-to-fracture test. Results: The highest mean fracture strength was found in Group D (936.0 ± 354.7) and lowest in Group A (684.2 ± 466.9). Fracture strength was higher in groups where FRC was used as a base material than plain restorations. However, there were no significant differences between the Lava and Cerasmart groups with and without FRC ( p > 0.05). Most of the samples were irreparably fractured under CEJ. Conclusion: Using short FRCs as a resin base material did not significantly improve fracture resistance. Cerasmart and Lava blocks had similar fracture resistance and fracture pattern.

“…Reviewing the literature pertaining to onlays is complicated by the fact that authors classified restorations of widely dissimilar designs as onlays. In several publications, restorations of similar designs were referred to as onlays or crowns based on minor differences such as a minor changes in the position of the gingival margin, different remaining cusp height, or the existence of a small extension into the endodontic chamber 47–49 . Two studies (Lin et al 50 and Lin et al 51 ) were excluded because in these studies, both the onlay and crown groups were technically crowns of similar design.…”

ObjectiveTeeth prepared for mesial‐occlusal‐distal (MOD) restorations have a significant risk of cusp fracture. Crowns and onlays can provide cusp coverage to reinforce posterior teeth at risk. Onlays are often more conservative of tooth structure which may be an advantage for teeth with large MOD preparations. It remains uncertain how onlays and crowns compare for posterior teeth with MOD tooth structure loss. The purpose of this systematic review was to compare the resistance to fracture, success rate, survival rate, and failure rate of teeth with MOD preparations restored with onlays or crowns.Materials and MethodsAn electronic search queried Medline (PubMed), Embase (Ovid), Scopus, the Cochrane Library, and grey literature (OpenGrey) from database inception through April 29, 2023.ResultsAfter eliminating duplicates and irrelevant records, 32 manuscripts were assessed. Only three publications met the criteria for inclusion. Most exclusions were due to poor reporting of restorative design and the amount of tooth structure remaining, or due to combining various restorative designs. Due to the limited sample size and high heterogeneity, no meta‐analysis was conducted. One study observed a better outcome for onlays and two observed no difference. All three studies reported the mode of failure for crowns as more catastrophic whereas teeth with onlays could be salvaged.ConclusionsOnlays may be an advantageous alternative to crowns for teeth with MOD preparations, but the level of evidence is insufficient to draw meaningful conclusions.Clinical SignificanceCurrent evidence is insufficient to determine whether onlays or crowns are providing a different outcome when used to restore posterior teeth with MOD tooth structure loss. However, the fracture of teeth with MOD tooth structure loss restored with onlays appears to be less catastrophic than when restored with crowns.
