The aim of removable prosthodontics is not only to restore lost oral structures but also to preserve the remaining tissues. Implant-retained overdentures have shown superior outcomes over conventional dentures by reducing residual ridge resorption, enhancing prosthesis support and retention, and improving patients' quality of life. Retention can be further optimized through the use of various attachment systems such as bars, studs, magnets, and telescopic crowns. Traditional PMMA denture bases have limited flexibility, making their extension into soft-tissue undercuts challenging. The introduction of flexible resin materials has improved adaptation to deeper undercuts, enhancing retention while minimizing patient discomfort and absorbing functional stresses. Additionally, flexible resins may reduce microbial colonization by improving blood circulation to the underlying mucosa and supporting salivary defense mechanisms against Candida albicans. Recently, innovative attachment systems such as Novaloc have been developed, featuring PEEK retentive caps and an amorphous diamond-like carbon coating to minimize wear and maintain long-term retention. Their versatile design allows better accommodation of gingival variations and contributes to improved patient satisfaction and treatment success.
