An innovative guided direct composite resin restoration technique for managing tooth surface loss and dental anomalies

Direct composite resin restorations are increasingly being recommended as a minimally invasive treatment option for oral rehabilitation in patients with tooth wear or inherited dental anomalies, eg microdontia, amelogenesis imperfecta. These restorations are relatively economical compared to cast restorations and reversible, with high survival rates of up to 90%.^{1, 2}

A major drawback for this treatment is the time required for building up several affected teeth with composite resin. Apart from increasing the cost of treatment, the lengthy procedure makes it unsuitable for less co-operative patients (eg children) and those with special needs who, due to physical or mental conditions, find it difficult to co-operate throughout treatment. Studies showed that longer procedural time results in poorer survival rates at seven years.² These two factors may negatively affect the survival rate or aesthetic outcomes or, in some cases, may result in the treatment being denied.
