“…On the other hand, a study by Komada et al 23) -which investigated the fracture resistance of extracted mandibular premolars restored with different post materials, no crowns, and two different bone levels (2 or 5 mm below CEJ) -found no significant differences in fracture resistance between the two levels of bone loss. A study by Ni et al 24) -which investigated the fracture resistance of singlerooted premolars restored with GFPs, metal alloy crowns, and two different bone levels (2 or 6 mm below CEJ) -also found no statistical differences in fracture resistance between the different bone levels. In the present study, results did not show any difference in terms of fracture resistance between different bone levels.…”

“…Data on the influence of bone level on fracture type are conflicting, thus rendering the role of bone support debatable. Komada et al 23) and Ni et al 24) found that specimens with bone loss showed more unrestorable root fractures than those with normal bone level. Naumann et al 22) obtained less uniform data, with different fracture types exhibited for different levels of bone loss.…”

This study evaluated the combined influence of horizontal bone loss and post length on the fracture resistance of endodontically treated teeth (ETT). Twenty premolars were endodontically treated and divided into four groups of two different post insertion depths (5 and 7 mm) and two alveolar bone levels from cement-enamel junction (2 and 5 mm). After posts (RelyX Fiber Post) were cemented using a self-adhesive resin cement (RelyX Unicem Aplicap) and cores were built up (Filtek Supreme XT Universal Restorative, 3M ESPE, USA), cobalt-chrome copings were luted to each prepared tooth. All specimens were subjected to thermocycling and mechanical loading until fracture occurred. Mean fracture loads (N) were 1,445±342.2 (2 mm bone level/5 mm depth), 1,516±413.4 (2 mm bone level/7 mm depth), 1,736.4±1113.8 (5 mm bone level/5 mm depth), 1,038.6±600.2 (5 mm bone level/7 mm depth). No significant differences were found. Therefore, bone level and post length did not seem to influence the fracture resistance of ETT.

“…The removal of pulp and root dentin diminishes a protective feedback mechanism and reduces the stress-strain capacity of the teeth, compromising the root fracture resistance [4,28]. The stability of the teeth is reduced by endodontic preparative procedures, leading to more root deformations and less stiffness [29,30]. The success of restoration techniques for endodontically treated teeth is dependent upon variations in length, diameter and shape of a post.…”

“…The impact of the periodontal status on the survival of endodontically treated teeth was observed [43,44]. As the height and density of the alveolar bone changes, tooth mobility increases due to the reduced support, altered centers of resistance and the associated increased moment of force [30]. A finite element study suggested that dentin stresses were 4-10 times higher than in teeth with normal bone height when the bone height is 6 mm below the cemento-enamel junction [45].…”

“…Periodontitis not only causes bone loss, but also increases the failure rate of endodontic treatments [12]. A linear relationship was discovered between the amount of horizontal bone loss and the magnitude of force encountered by restored teeth [13].…”

Abstract.To investigate the stress distribution of a severely damaged maxillary anterior tooth restored with a computer-aided design/computer-aided manufacturing (CAD/CAM) glass-fiber post system. Twelve models were fabricated with different alveolar bone levels and cervical dentin wall thicknesses and studied using a two-dimensional finite element method. A force of 100 N was applied to the lingual surface of the crown at 45 degrees, and the maximum von Mises stress was calculated. A higher stress level was observed in the dentin than in the post and crown. With the reduction of dentin thickness, the maximum von Mises stress in the dentin increased slightly to a peak at a thickness of 1.5 mm, followed by a slight decrease at a thickness of 1.0 mm. However, the relative ratio (RR) values did not show a large difference (RR > 80%). Meanwhile, a large difference in RR values was observed with a change in bone level (RR < 80%). When using a CAD/CAM glass-fiber post system, the maximal von Mises stress was significantly affected by the bone level, rather than by the dentin thickness. Moreover, this system may be applied to the treatment of a maxillary anterior tooth with a bone level of only 2/3.
