Abstract
INTRODUCTION: This case report highlights the clinical application of stamp and injection molding techniques for the restoration of young permanent teeth, as efficient, esthetic, and less invasive alternatives to conventional restorative approaches. However, each has distinct limitations that should be taken into consideration for optimal clinical outcomes. REPORT: The first case was an anxious 14-year-old girl, who presented to the Postgraduate Clinic of Paediatric Dentistry Department (NKUA), for the restoration of a right upper first permanent molar. Intraoral examination confirmed an extensive occlusal carious lesion involving the distobuccal cusp. Given the need for direct esthetic and functional restoration, the injection molding technique was selected as the most appropriate treatment approach ensuring precise anatomical replication and seamless restoration with the least clinical time and effort, reducing the stress of the patient. The second case was a 9-year-old girl, also examined at the clinic with carious lesions on the occlusal surfaces of the first permanent mandibular molars, but without extensive tissue loss. Given the nature of the lesions, the stamp technique was chosen as the preferred method of restoration, allowing for quick and efficient restoration by replicating the tooth's original morphology. Both techniques provided functional and esthetic results, proving their effectiveness in pediatric restorative dentistry while minimizing chairside time and preserving natural tooth structure. CONCLUSION: Stamp and injection molding techniques offer promising alternative solutions for direct composite restorations of posterior permanent teeth in young patients. Their ability to provide predictable, esthetic, and efficient restorations underscores their clinical significance. However, careful case selection, meticulous application, and periodic recall examinations remain essential to optimize their outcomes and ensure long-term success.
