8 INDUSTRY Dental Tribune Middle East & Africa Edition | 1/2018 SDR® Plus – The only bulk-fi ll material with multiple years of clinical success By Dentsply Sirona In 2009, SDR® was the fi rst tech- nology that allowed 4mm bulk placement in fl owable consistency, providing an unmatched combina- tion of consistency, excellent cav- ity adaptation, unique self-leveling and minimal shrinkage stress. Now, with the introduction of SDR® Plus, all the benefi ts of the SDR® technol- ogy remains plus expanded indica- tions, more shades, improved wear resistance and increased radiopac- ity. While making Class I and Class II restorations faster and easier, the SDR® technology in SDR® Plus mate- rial still provides excellent long-term reliability in several 5- and 6-year clinical studies. In fact, the long-term survival rates of bulk fi ll restorations with SDR® technology proved to be equivalent to those of restorations done in the conventional layering technique, highlighting SDR® Plus as a quality and durable fi lling material. Split mouth studies by J.W.V van Dijken and U. Pallesen1,2 During the 6-year follow-up, a total of 98 Class I and Class II restorations were evaluated at recall. 49 using SDR® and ceram.x® SphereTEC™ in the bulk-fi ll technique against the same number using just ceram. SDR® Plus x® SphereTEC™ composite in the layering technique. The observers concluded that SDR® was clinically safe, gave highly acceptable clinical durability, and noted that the clini- cal performance and failure rate was equivalent to conventional layering (3 failures in both test and control group). During the 5-year follow-up, a total of 183 Class I and Class II restorations were evaluated at recall. 92 using SDR® and ceram.x® SphereTEC™ in the bulk-fi ll technique against 91 using just ceram.x® SphereTEC™ composite in the layering technique. The observers concluded that both restorative techniques showed good surface, marginal stability and col- our stability. They also mentioned that there was no statistically differ- ent annual failure rates between the bulk-fi ll and layering technique, and all restorations successfully resulted in no post-operative sensitivities. “The use of a 4mm incremental technique with the fl owable bulk- fi ll resin composite showed during the 5-year follow up slightly bet- ter, but not statistically signifi cant, compared to the conventional 2mm layering technique in posterior resin composite restorations.”2 36 month clinical trial results by J. Burgess and C. Munoz3 The initial study entailed 170 resto- rations where SDR® was bulk fi lled in increments of 4mm and then capped using Dentsply Sirona’s now discontinued composite material Esthet•X® HD. Since the beginning of the trial the restorations have been individually evaluated at 12, 24 and 36 months. At each evaluation the parameters for assessment were fracture and surface defect, proximal contact, recurrent caries, sensitivity and gingival index. We are pleased to announce that the key fi ndings of the clinical evaluation were as fol- lows: • There were no failures attributable to SDR®. • Acceptable performance with re- spect to safety and effi cacy after 3 years. • No post-operations have been re- t the same number using just SDR/Ceram·X (n=49) Sur9i9ed: 46 Failed: 3 SDR/Ceram·X (n=92) Sur9i9ed: 88 Failed: 4 Ceram·X (n=91) Sur9i9ed: 85 Failed: 6 ported related to SDR®. • No recurrent caries associated with SDR®. • No reports of adverse events. • No adverse effects on the gingiva in contact with SDR®. “There were no observations of re- current caries associated with the low stress resin and no reports of adverse events throughout the dura- tion of the trial.”3 Conclusion With more than 50 million applica- tions since its introduction in 2009 and superior performance in clinical studies, it comes as no surprise that SDR® Plus has become the bulk fi ll technology of choice for the creation of reliable direct restorations.
