A 35-year-old male patient presented with a peg-shaped maxillary left lateral incisor. The patient’s dental history revealed multiple direct composite restorations placed since the age of 16, all without tooth preparation. The restorations had failed approximately every two years because of fractures or severe marginal discoloration.

Clinical assessment and pre-operative evaluation

Dental dam isolation was performed, and baseline clinical photographs were taken. The existing restoration had been placed solely to close the mesial and distal diastemas, resulting in significant marginal discrepancies and morphological disharmony (Fig. 1). A palatal view revealed a more critical issue: concave, non-cleansable proximal contact areas, favouring food impaction that could increase periodontal risk (Fig. 2).

Restorative treatment and six-month follow-up

The failing composite was completely removed without compromising the underlying natural tooth structure. Following removal of the composite, the tooth required augmentation of the mesial and distal surfaces, incisal edge and labial surface (Fig. 3).

The key anatomical considerations during reconstruction were:

• inciso-cervical position of the mesial and distal contact areas;
• contact area geometry (point versus surface contact);
• incisal edge position and line angle symmetry; and
• correct palatal wall orientation.

To support a streamlined workflow, the Universal Excellence portfolio (Kuraray Noritake Dental) was selected. CLEARFIL MAJESTY ES-2 Universal in Shade U was chosen to provide predictable and harmonious aesthetics with a single-shade approach, allowing the clinician to focus on the primary anatomical determinants of form and function rather than complex multi-shade layering.

CLEARFIL Universal Bond Quick 2 was applied using a simplified one-step protocol, providing rapid and reliable adhesion. The composite was then applied using a layering technique to minimise polymerisation shrinkage stress and gradually establish the planned anatomical form (Figs. 4 & 5). The postoperative results demonstrated seamless integration with the surrounding dentition (Figs. 6–8).

The patient was recalled after six months for evaluation. The restoration retained its lustre and marginal integrity and showed no visible wear or staining (Figs. 9–11).

Conclusion

While complex layering techniques can enhance optical properties, they may inadvertently shift the focus away from fundamental anatomical principles. The Universal Excellence portfolio from Kuraray Noritake Dental offers a practical and dependable solution for complex morphological challenges that enables clinicians to focus on anatomical reconstruction and supports long-term clinical success.
