Clinical assessement of ceramic inlays compared to resin composite inlays- literature review

The development and enhanced performance of restorative dental materials—both direct and indirect restorative materials, along with adhesives—are paving the way for minimally invasive dental treatments. High-performance composite resins and ceramic materials, when appropriately matched to the clinical case, ensure excellent restorative outcomes. These outcomes include superior aesthetics, precise marginal fit, conservative or minimal tooth preparation, strong adhesion, and long-term success. Materials and Methods This systematic review analysed various published studies with similar objectives and a minimum follow-up period of 3 years. The outcomes assessed included quantifiable factors such as tooth and restoration fractures, chipping of both teeth and inlay restorations, the frequency of endodontic issues, secondary caries, and debonding. Results and Discussions The selection of a material for inlays and onlays need to absorb significant occlusal forces. Consideration regarding the durability and effectiveness of the selected materials used through direct or indirect technique and clinical case are essential for a long-term success. The survival rate of adhesive restorations is heavily influenced by factors like dental cement and adhesive system, marginal fit, bruxism and interdental contact areas. Conclusions: Ceramic inlays and onlays have shown higher survival rates over a 5-10 year period of time compared to alternative materials such as composite resin. Fractures is the most frequent type of failure for composite resin restorations. This evidence indicates that ceramic inlays are a highly successful treatment option with a very favourable prognosis.
