Abstract

BACKGROUND Replacing missing teeth in the anterior region of the jaw can be challenging due to the limited available interdental space. Improper selection or inadequate placement of a dental implant in this situation can affect the adjacent anatomical structures negatively. What if, in addition, a residual intraosseous chronic inflammatory lesion was present? The objective of this case report is to demonstrate the step-by-step surgical procedures of replacing a maxillary lateral incisor in a patient with a residual lesion with a satisfactory outcome. CASE REPORT A 63-year-old female patient with an extracted maxillary lateral incisor presented for implant placement. Radiographically, a residual periapical lesion with mild atrophy of the alveolar bone and fairly low density with sparse trabeculation was noted. Owing to the limited restorative space, a Straumann Bone Level Tapered Implant Ø2.9 mm (Small Cross-Fit connection, Roxolid, SLActive) was placed. Histopathological evaluation revealed a definitive diagnosis of periapical granuloma. After 1 year, the clinical examination revealed a successful outcome, and the patient was satisfied with the result. CONCLUSIONS This case report shows a successful clinical and radiographical outcome after 1 year of a 2-piece small diameter dental implant, the Straumann Bone Level Tapered Implant, diameter 2.9 mm, replacing a missing maxillary lateral incisor after enucleating the lesion with histopathological examination.
