Immediate Implant Post-Extraction of Impacted Maxillary Canine: Systematic Review

Introduction: When impacted maxillary canines are not amenable to orthodontic traction or reimplantation, extraction is the only option available, followed by implant placement; this is a challenge due to the bone resorption frequently associated with complex tooth extraction that often necessitates bone grafting. Immediate dental implant placement appears to be the adequate strategy to replace missing teeth. Objective: The aim of this systematic review was the evaluation of implant placement immediately after removal of maxillary canine impacted. Methods: Detailed search in PubMed and Cochrane databases to obtain information on all reported cases and postoperative outcomes. There were no restrictions with regard to publication status or language of publication. Selection criteria: Only included all clinical reports of at least 1-year follow up and that treated by immediate implant in maxillary canine impacted extraction. Results: The initial database search produced 135 titles, after careful examination only 11 reports considered to be met the criteria for inclusion. The remaining reports were to be no met the criteria for inclusion. The results indicated a success rate significant for the procedure of immediate implant placement into impacted maxillary canine extraction socket accompanied by guided bone regeneration (GBR). This procedure allowing implant anchorage and primary stability to achieved. Conclusion: Our review suggest that this treatment is viable and with a good outcome, although more works is needed to determine adequate the results and thus determine the potential impact of this treatment alternative.
