“…Then the matrix with provisional material is placed on the prepared teeth and allowed to polymerise.The heat produced during polymerisation can be dissipated using air water syringe.Once the material reaches the rubbery stage,the restoration was repeatedly reseated until complete setting so as to avoid locking of the restoration during polymerisation. (Gratton and Aquilino, 2004) (Deines, 1988;Haddix, 1988) Indirect temporisation technique uses an irreversible hydrocolloid /non aqueous elastomeric impression after tooth preparation,which was then poured with fast setting plaster/stone.The matrix was then trial checked on the cast followed by fabrication of the provisional restoration directly on the cast (Gratton and Aquilino, 2004;Abdullah, Pollington and Liu, 2018).Indirect -direct temporisation which is a combination of two techniques is considered to provide the most accurate fitting prosthesis providing better periodontal and prosthetic outcome.…”

Temporary restoration are used for short or long term between the time of tooth preparation until the definitive indirect restorations are fitted.Various techniques are used to fabricated these restorations-direct ,indirect ,combination of both.The aim of this study was to assess the preferred method of temporisation in single teeth crown preparation.This study was conducted at a private dental institute between June 2019 to March 2020. 86000 patient records were analyzedTotal of 976 teeth which had temporary crowns following single tooth crown preparation were included and assessed for technique of fabrication with gender of the patient,type of teeth temporised and the technique used for temporisation.The tabulated data was analysed using SPSS software .Incomplete date were excluded from the study.Statistical analysis was done using a chi -square test.In our study we observed that maximum number of temporisation procedures was done in males with predominance in maxillary posteriors.Association between the type of teeth restored and the temporisation technique showed that direct technique was the most preferred technique and it was most commonly done in maxillary posteriors (p <0.05).The interim restoration plays a significant role in maintaining the occlusal function and protects the prepared tooth, hence proper temporisation is required following tooth preparation.

“…Restoration repair is usually not satisfactory (each repair severely weakens the material), or even impossible, and the preparation of a new restoration unnecessarily takes both the patient's and the dentist's time. Moreover, it increases the cost of treatment [1,4,8,9,10].…”

Objectives. The objective of the research was to define the mechanical properties of currently marketed temporary filling materials. Methods. Eight temporary filling materials: Boston, Dentalon, Protemp II, Revotek LC, Structure 2, Structure 3, UniFast LC, UniFast Trad were used to make 5 samples each of measurements 2 × 2 × 25 mm, in order to define the flexural strength, and 10 rings each of measurements 2 × 5 mm, in order to carry out the Vickers micro-hardness test. After preparation, the samples were stored in distilled water of temperature of 370°C, for 7 days. Subsequently, flexural strength and Vickers hardness testing was undertaken. Results. Composite temporary materials showed considerably better mechanical properties, both in flexural strength and in Vickers micro-hardness testing. Conclusions. the best mechanical properties, both in terms of flexural strength, as well as Vickers micro-hardness test can be observe among composite materials.

“…The Disadvantages of PMMA have been identified as high level of monomer release, exothermic reaction, and polymerisation shrinkage. 9 The Visible Light Polymerized (VLC) materials was first introduced in the 1980s, and contained urethane dimethacrylate, a resin whose polymerization is catalyzed by visible light and camphoroquinone as initiator. 4 UDMA usually incorporate filler such as microfine silica to improve physical properties like reduced polymerization shrinkage.…”

Statement of problem: Flexural strength is important in determining the strength of interim restorations and it is especially important in long span and long term interim restorations. Studies comparing the flexural strength of provisional restorative materials are limited and inconclusive. Aim: To compare the flexural strength of provisional restorative material fabricated using light polymerized composite resin, Urethane dimethacrylate (UDMA) and auto polymerized resin, Poly Methyl Methacrylate (PMMA) Materials And Methods: This study included 40 specimens. Twenty bar-shaped specimens were fabricated for each group Polymethyl Methacrylate (PMMA), and Urethane dimethacrylate (UDMA) with the use of a split machined metal mold. These specimens were stored in artificial saliva for 10 days. Flexural strength was calculated using three point bending test under universal testing machine. Data were analysed using student-ttest (α=0.05) @ 90% power. Results: The mean flexural strength of provisional restorative specimen fabricated using Poly Methyl Methacrylate (PMMA-134.1 Mpa) was significantly higher than Flexural strength of provisional restorative specimen fabricated using urethane dimethacrylate (UDMA-107.8 Mpa). Conclusion: Within the limitations of this study by analyzing the results, it was concluded that the flexural strength of polymethyl methacrylate (PMMA) is comparatively better than the flexural strength of Urethane dimethacrylate (UDMA). PMMA could be a better provisional restorative material for an extended period, when the patient exhibits parafunctional habits, or when long-span prosthesis is planned.
