title: A retrospective analysis of 12 immediate-implant restorations in the maxillary premolar region.
abstract: BACKGROUND
  A retrospective analysis was performed of 12 consecutive patients who received implant placement with concurrent restorations in the maxillary premolar region as part of the General Practice Residency Program. The emergence profile established during the healing phase was then captured using a customized impression coping prior to fabrication of the final restoration. The patients were followed for a period of at least 1 year.
  
  
  RESULTS
  All 12 cases showed normal healing and resulted in functional implant crowns. Two cases required an additional appointment for re-tightening of the temporary abutment screw.
  
  
  CONCLUSIONS
  With a favorable occlusal scheme, immediate implant restorations in the maxillary premolar region can be considered when primary implant stability is achieved at the time of placement.
