摘要

There exist several treatment planning and clinical challenges when treating over-retained primary teeth with dental implants-especially in the esthetic zone where the existing hard and soft tissue positions are not in harmony with adjacent dentition and do not serve as reliable landmarks for implant placement and restoration. In this report, we highlight some of the key aspects for achieving predictable treatment outcomes for implant restorations replacing over-retained primary teeth in the esthetic zone.This clinical report describes the treatment of a patient who presented with over-retained deciduous canines consequent to congenitally missing maxillary lateral incisors. The deciduous canines were deemed hopeless, and subsequently replaced with immediately placed implants following a computer-guided protocol. The optimal implant positions were determined through a diagnostic wax-up correcting the existing gingival discrepancies with the adjacent teeth. Existing periapical infections were addressed utilizing a vestibular approach to minimize the postoperative recession and scarring and achieve a more predictable esthetic outcome. Final restorations were fabricated with all ceramic materials for optimal esthetics.When planning for implants to replace over-retained primary teeth, it is essential to visualize the desired contours of the final restorations and correct the level of the existing gingival discrepancies by planning the proper implant position and angulation in relation to the adjacent teeth and gingival positions.Careful treatment planning coupled with a guided implant workflow allows for a successful surgical and esthetic outcome for the replacement of over-retained primary teeth with implant restorations.
