“…1 However, as in the case of natural teeth, the bonded brackets should have sufficient bond strength to withstand orthodontic forces. A weak bond of the brackets to provisional materials will lead to a high failure rate, with adverse consequences on the cost and efficiency of orthodontic therapy as well as on patient comfort.…”

Objective: To evaluate the combined effects of material type, surface treatment, and thermocycling on the bond strength of orthodontic brackets to materials used for the fabrication of provisional crowns. Materials and Methods: Four materials were included in this study (ProTemp, Trim Plus, Trim II, and Superpont C+B). Sixty cylindrical specimens (1 3 3 cm) were prepared from each material and equally divided into three groups. The first group was ground with silica carbide paper, the second was polished with pumice, and the last group was sandblasted with 50-mm aluminum oxide particles. Stainless-steel maxillary central incisor brackets (Victory Series, 3M) were bonded to the provisional material specimens with Transbond XT light-cured composite resin, and half of the specimens from each group were thermocycled 500 times in 5uC and 55uC water baths. Then the brackets were debonded with shear testing, and the results were statistically analyzed by threeway analysis of variance and Tukey's multiple-comparison tests at a 5 0.05. Adhesive Remnant Index (ARI) was also identified. Results: Before and after thermocycling, ProTemp materials showed the highest shear bond strength with orthodontic brackets (10.3 and 13.1 MPa, respectively). The statistical analysis indicated an interaction among the three independent variables (P , .05) and statistically significant differences in bond strength among provisional materials (P , .001), surface treatments (P , .001), and thermocycling (P , .05). According to the ARI, most groups demonstrated adhesive failure. Conclusions: The provisional material type, surface treatment, and artificial aging have a significant effect on bond strength. Sandblasting treatment exerts a beneficial effect on shear bond strength. (Angle Orthod. 2014;84:649-655.)

“…The importance of provisional restorations in both conventional and implant prosthodontics, is well documented in the dental literature [1] and the requirements for satisfactory provisional restorations differ only slightly from the definitive treatment they precede. The rationale for provisional coverage of teeth and implant abutments identifies multiple areas of concern including aesthetics, comfort, speech, function, periodontal health, maxilla-mandibular relationships, and continued evaluation of the fixed prosthodontic treatment plan [2][3][4].…”

“…The patient can really visualize the treatment outcome and understand the possible limitations [6]. Finally, the occlusal scheme can be evaluated [6], as well as the potential consequences from an alteration in the occlusal vertical dimension [1].…”

The aim of this study was to investigate the marginal accuracy of three currently used methods of direct provisional crown construction for the accuracy of marginal fit during in vitro fabrication. Three groups of provisional crowns were investigated using a modified McLean and von Fraunhofer technique. Proprietary provisional crown coping modified to tooth shape with a Bis-acryl temporary material was compared to Bis-GMA and isobutyl methacrylate resin provisional crowns with modified margins using a light cured flowable composite and 'bead on' isobutyl methacrylate respectively. Data was analyzed with the Mann Whitney test (a = 0 .05). Reliability was determined using the Bland Altman test. Bis-GMA acryl resin composite relined with flowable composite produced significantly better fitting restorations compared to the two other groups.

“…It might be that lack of attention to the provisional stage could have a negative impact on the predictability of our implant treatment. Thus, the significance of the provisional stage on implant dentistry cannot be overstated [3].…”

Objective: Implant-supported interim prostheses aims to preserve the natural periodontal architecture, protect the surrounding tissues, and provide patients with immediate esthetic and functional outcomes. The objective of this clinical technique article is to present a reliable method to replace an ailing interim implant-supported fixed partial denture (FPD). Clinical considerations:Patient presented with an ailing interim implant-supported fixed partial denture (FPD) replacing all lower anterior incisors. After case was clinically and radiographically evaluated, diagnostic casts were mounted. Once the interim FPD was retrieved, provisional abutments were dislodged and cleaned. Implant impression copings were carried out intraorally using pattern resin; its respective implant replicas were attached and screwed. Healing abutments were hand-screwed to keep the periimplant tissue architecture until the delivering of the newly fabricated interim FPD. The implant impression copings and its respective implant replicas were positioned on the diagnostic cast using dental stone. The two provisional abutments were positioned on the implant replicas and screwed in place for the relining of the new interim prosthesis previously made with acrylic resin. The new interim FPD was finished, polished and delivered. Conclusion:This clinical technique presents a reliable method for fabricating an immediate interim implant-supported FPD to replace an existing ailing interim prosthesis.assess proposed occlusal schemes before definitive restoration is placed [9].Provisional restorations designs appertain to implant therapy range from the removable acrylic resin complete denture to implantsupported fixed prosthesis [4][5][6][7][8]10,[14][15][16][17][18][19][20].The multiple clinical challenges (e.g. complex biomechanics, time management and periimplant tissue' architecture), dictates the type of material required. Generally, the aforementioned techniques are modeled by anecdotal and observational information, and are conveyed from natural tooth provisional techniques.Contemporary materials for interim prostheses include polymethyl methacrylate (PMM), polyethyl methacrylate, polyvinyl ethyl methacrylate, bis-acryl composite resin, and visible lightpolymerized urethane dimethacrylate [21]. Besides its inherent exothermic reaction [9,[22][23][24] and volumetric shrinkage [23,[25][26][27], PMM have shown-among the literature-better physical properties [9,[27][28][29][30], color stability [27,31], and durability [9,27,32]. The present technique utilizes an indirect approach, were its fabrication takes place on the laboratory. The indirect technique eliminates the problems associated with the direct technique such as less accuracy on the margins, more chemical and thermal irritants around the tissues and more chances to locked the interim prostheses due to surrounding undercuts [28,29].By utilizing the indirect technique with PMM in implant dentistry, our expected clinical outcomes have more chances to be colored by the "tincture of...
