INTRODUCTIONRehabilitation of partially edentulous patients using fixed partial denture (FPD) is a well-established treatment protocol since many decades. These FPDs require a laboratory phase of fabrication that varies from days to weeks. A dimensionally stable, strong, and accurate interim restoration is an important component of this treatment modality. These interim restorations provide pulpal protection, positional stability, occlusal function, strength, and aesthetics.Polymethylmethacrylate (PMMA) is the most common material used to fabricate interim FPDs. This material lacks sufficient strength and hence various methods are being used for reinforcing it in the past like glass fibres, carbon fibres, kevlar fibres, polyethylene fibres, and stainless steel wire.1-4 To date, little information is available in the literature on fracture resistance of reinforced PMMA temporary crown and bridge materials. It is also not clear as to how the site of placement of fibre reinforcement, influences the fracture resistance of temporary crown and bridge materials. Therefore, this study was undertaken to evaluate the fracture resistance of interim FPDs using different types of fibre reinforcements and also to determine the most appropriate site of reinforcement of interim FPDs fabricated from PMMA. MATERIALS AND METHODThis study was designed in two stages. In the first stage various methods of reinforcement for interim FPDs made up of PMMA were evaluated. During the second stage, favourable sites of placement to strengthen the interim FPDs were evaluated. There were five groups of ten samples each namely the group 1 (unreinforced, control group), group 2 (glass fibrereinforced), group 3 (polyethylene fibre-reinforced), group 4 (glass and polyethylene mixed fibre) and group 5 (stainless steel reinforced).Samples were tested for fracture resistance in an Instron universal testing machine. The maximum load causing the initial fracture and fracture resistance were calculated. The mean and standard deviation for each group were determined. The data was analysed for differences using one way analysis of variance (ANOVA) (The Tukey's standardised range test) to An evaluation of fracture resistance of interim fixed partial denture fabricated using polymethylmethacrylate and reinforced by different fibres for its optimal placement: an in vitro study Col

Background:The choice of restoring endodontically treated anterior teeth is guided by strength and esthetics. The ultimate shade of post and core definitely affects the translucent ceramic crown systems, which is a matter of concern. The colour of the underlying core influences the definitive esthetic result especially for a highly translucent ceramic crown with a thickness of less than 1.6 mm. In case of a thin gingival biotype the cast posts may also create root discoloration and a blue-gray effect. The gold posts, which is considered as gold standard, exhibit a dull bluish hue and give an unnatural appearance. The utilization of a dissimilar material for post and core buildup often results in failure due to separation between the post and core. When the core and the foundation restoration is of ceramic, post based on ceramic material would ensure better success. The prefabricated zirconia posts are one of the novel alternatives to gold post. Purpose: The mechanical advantage together with the aesthetic gain over the conventional materials has made zirconia the state of art option available for usage in the present day. Materials and Methods: There are only few relative studies, which have reported on aesthetic, clinical survival and patient reported events of endodontically treated teeth with zirconia post. Hence this clinical study is undertaken to evaluate the acceptability of prefabricated zirconia post used in endodontically treated teeth especially in the anterior region with the foundation restoration being all ceramic restorations. Results: Zirconia post is a more aesthetic alternative to fiber post especially in patients with gummy smile and thin biotype with all-ceramic crown to optimize the esthetic effect at the root and maintaining an adequate level of strength. Conclusion:In esthetic zone prefabricated zirconia post is a more simple and viable option to conventional post giving a monoblock (one piece) design.

The ever-increasing speed of life puts forth a need to improve the outcome of the rehabilitative and other interventions we perform on our patients. This improvement in efficacy is primarily focused on reducing treatment time while enhancing the durability of the rehabilitation without compromising on patient safety. Strategic Corticobasal Implants (SCI) offer both versatility and durability to cater to all kinds of clinical scenarios which cannot be managed by conventional implants and or require extensive adjunctive procedures. Materials and Methods: A total of 265 BECES implants were placed from Mar 2017 to Feb 2018. It is a single piece, polished surface, bendable implant manufactured by Ihde Dental, Germany. A variety of cases were managed ranging from full mouth rehabilitations, segments, and single tooth loss. The results were assessed after a period of one year. Results: A total of 06 implants failed. Remaining 259 implants reported no complication over the past one year. Conclusion:The SCI are very versatile in the management of edentulous cases with an incredibly low failure and complication rate.

Confident attractive smile is the most important social bonding gesture and key to your professional enhancement. With the advent of new materials and techniques in the field of esthetic dentistry, people have transformed their idea of smile and how it's designed. In today's era we have digital smile design as a multipurpose digital tool with certain clinically relevant advantages. It has enhanced the esthetic diagnostic capabilities with much more organized treatment plan and better communication among the team members and patient thereby resulting in more predictable treatment outcome and increased effectiveness of case presentation and patient motivation.
