Quality and Survival of Direct Light‐Activated Composite Resin Restorations in Posterior Teeth: A 5‐ to 20‐Year Retrospective Longitudinal Study

Abstract

In the present report, direct light-activated composite resin restorations in posterior teeth showed a high clinical success rate and long-term mean survival time. These composite resins might be considered the material of choice to restore medium, extended, and in some clinical situations, large preparations in posterior teeth.

Estudio clínico retrospectivo, de 656 restauraciones de oro colado en dientes posteriores, entre 5 y 44 años: Análisis de los resultados

“…According to Ryge's criteria (40) modified by the authors, the results on the quality of the variables analyzed are presented in Table 4. Considering these results, and the previous established criteria (32) , the CS of the GIOs in function was 93.6%. The CS for the whole sample was 76.1%.…”

“…As was previously published (32) , four success criteria (SC) were established on the quality of the GIOs: -Excellent (Ex): When MA, MD, and S were rated "Alpha" in the same GIO. This group represents the best quality restorations.…”

“…From April 2013, a retrospective clinical longitudinal study on six restorative procedures, performed by the first author in his private practice, has been conducted covering a 44-year period. Four articles have been published (12,32,37,38) . This paper presents the results of a new study in the series.…”

“…Clinical studies and systematic reviews have shown very good results (7)(8)(9)(10)(11)(12) . Moreover, improving biomechanical and optical properties in direct light-activated composite resins (13)(14)(15)(16)(17)(18) , as well as in the adhesive systems (19)(20)(21)(22) has increased their use (23)(24) , showing high long-term clinical success, performing extended and large restorations in posterior teeth (25)(26)(27)(28)(29)(30)(31)(32) . This scientific evidence has provided the basis for using these materials as substitutes of cast gold restorations.…”

Annual review of selected scientific literature: A report of the Committee on Scientific Investigation of the American Academy of Restorative Dentistry

“…One article describes the 5 to 20 years follow-up of 103 light-activated composite resin restorations placed in posterior teeth by a single operator. 320 The mean survival time of restorations still in function was 11.7 years, with 98% still being in function and 95.1% rated being clinically acceptable.…”
