“…Studies have clearly shown that oblique loads generate much more intense cervical stress than loads directed along the long axis of the tooth. [ 6 7 ] This is usually seen in single rooted teeth due to nonaxial loading. [ 8 ] A restoration must protect the tooth against these forces.…”

Aims:The aim of this study is to compare in vitro the fracture resistance of the endodontically treated tooth restored with a novel design Sharonlay, with the two component restorative method, i.e., post with separate onlay, and onlay without post.Subjects and Methods:45 single-rooted mandibular second premolars were taken, and root canal treatment was performed. Teeth were then randomly divided into three groups (n = 15) based on the type of restoration given: Group I - metal onlay with cast post extension (Sharonlay), Group II - metal onlay with prefabricated metal post (Mani post system), Group III - metal onlay over endodontically treated tooth obturated with Gutta-percha (control group). Fracture resistance was checked using the Instron universal testing machine and the fracture patterns were analyzed.Results:According to the values recorded, Group I showed maximum mean fracture resistance followed by Groups II and III. Statistically significant difference was found between Groups I and II and Groups I and III and statistically significant difference was found between Groups II and III.Conclusion:A single unit component Sharonlay, gives higher fracture resistance to a premolar as compared to (a) metal onlay with prefabricated metal post and (b) metal onlay over endodontically treated tooth.

“…Os RIRs fundidos são os mais versáteis em adaptação, pois podem reproduzir os condutos radiculares das mais diversas formas. Assim, propiciam melhor adaptação e distribuição de forças pela raiz ( CHAN; HARCOURT; BROCKHURST, 1993;EDMUNDS;DUMMER, 1990;SCHWARTZ;BLACKWELL, 1976;WALISZEWSKI;SABALA, 1978). Embasados na literatura, sabemos que os RIR fundidos obtidos pela técnica direta têm melhor adaptação às paredes do canal quando comparados aos RIR fundidos obtidos pela técnica indireta (PLAZA et al, 2002).…”

Endodontically treated teeth are often mutilated by caries and access requirements. The remaining structure requires special treatment to prevent further destruction. When a large portion of the clinical crown has been lost, it is often impossible to achieve sufficient anchorage of a restoration in the remaining dentin. In s uch situations, a root-canal-retained restoration is required. Only the root portion can offer the needed retention for a functional and esthetic artificial crown. Different approaches can be taken to the fabrication of cast posts and cores. In this study, direct method was chosen to fashion it, by auto polymerizing acrylic resin. We used six standard metal patterns that simulate an anterior tooth prepared to receive cast post and core. Burnout plastic patterns were fitted into the root canal and, using a fine sable hair brush, the polymer was introduced to fill the canal. After polymerization of the post, additional auto-polymerizing acrylic resin was added to form the core portion. This process can be repeated and correct if necessary. The acrylic resin patterns were then invested and casting was performed using nickelchromium alloy. The cast was removed from investment. Cleaning was performed exclusively to remove the small positive nodules on the metal post and sandblast surface. The aim of this research was to compare the marginal fit of 54 cast posts constructed with three auto-polymerizing acrylic resins: 18 of DuraLay (Reliance Dental MFG Co., USA); 18 of Pattern Resin (GC Products, Japan); 18 of Cop Clas (Artigos Odontológicos Clássico Ltda., Brasil). The posts and cores were seated over the six standard metal patterns. Marginal discrepancies were observed in scanning electron microscope (SEM). The measurements were registered and statistically analyzed. The results obtained showed that: (1) The cast post and core obtained from DuraLay (42,31 µm ± 9,54 µm) had significant best fit than the cast post and core obtained from the others acrylic resins, Pattern Resin (73,25 µm ± 32,86 µm) and Cop Clas (95,32 µm ± 45,02 µm) respectively; (2) No significant statistic difference occur (p=0,273) in the average marginal gap between the cast posts and cores obtained from Pattern Resin and Cop Class (22,07 µm ± 13,13 µm).

This clinical report describes a multidisciplinary approach for the rehabilitation of a young patient with mobile and missing front teeth. The objectives of the treatment were to eliminate tooth mobility and replacing missing tooth, while enhancing aesthetics and restoring masticatory function. Treatment included placement of endodontic stabilizer and rehabilitating missing tooth with fixed partial denture and gingival porcelain to satisfy the patient's aesthetic and functional expectations.
