Abstract

Abstract: The objective is to discuss the occurrence of infraocclusion after implant restoration in patients with missing upper anterior teeth,analyze and discuss the causes and clinical management methods of such complications. The patient's upper left central incisor was injured, and the crown and root were fractured subgingivally and could not be preserved. The affected tooth was extracted in a minimally invasive surgery and replaced by flapless immediate implant placement and immediate restoration. After 7 months, the zirconia ceramic crown restoration was delivered. CBCT and periapical radiographs with paralleling technique showed good osseointegration, sufficient thickness of the labial bone plate, and stabilization of marginal bone level. During the 5-year follow-up after implant placement, it was found that the implant settled and presented an infraocclusal situation.

Key words: Dental implant, Immediate implant placement, Immediate restoration, Infraocclusion, Implant settling
