Minimally Invasive Management of Localized Anterior Tooth Surface Loss Using Composite Injection Moulding and Dahl Technique: A Case Report and Follow-up

The loss of tooth tissue due to wear can be a significant concern for patients, especially when it affects anterior teeth. Many seek dental treatment to restore their worn teeth due to esthetic concerns, difficulties in maintaining oral hygiene, hypersensitivity, and a lack of self-confidence, all of which can impact their quality of life. This clinical report presents the management of a patient experiencing such challenges using contemporary restorative materials and techniques. The patient, who presented with tooth wear and sensitivity, was treated using the composite injection moulding technique in conjunction with the Dahl principle for localized anterior tooth wear. The treatment approach successfully restored both function and esthetics while preserving natural tooth structure. Over a three-year follow-up period, the composite restorations demonstrated excellent clinical outcomes, including improved occlusal stability, durability, and high patient satisfaction. This case highlights the effectiveness of a conservative Dahl approach in treating localized upper and lower anterior tooth wear, offering a minimally invasive yet highly functional and esthetic solution.
