title: Sinus Augmentation and Simultaneous Implant Placement Success: Pilot Study (2008-2011).
abstract: OBJECTIVE
  1) To describe implant success in the posterior maxillary when a sinus augmentation procedure was performed simultaneously with implant placement and then compare differences in success when sinus augmentation was delayed in patients attending the maxillofacial surgery clinic of the University of Puerto Rico, 2008 through 2011. 2) To determine sociodemographic characteristics, ASA classification, graft material, and final restoration and, using a questionnaire, determine as well patient satisfaction.
  
  
  METHODS
  A retrospective cohort study was conducted (approved by IRB) with 172 patients, using medical records. A total of 102 implants were placed in grafted maxillary areas, 55 placed simultaneously and 47 delayed. Patients were contacted, invited to participate, and, upon agreement, instructed to sign an informed consent.
  
  
  RESULTS
  A total of 45 implants were evaluated clinically (22 immediate and 23 delayed), all with 100% success (according to Buser and Weber criteria). In the sample group, 72.5% of the participants were women and 26.8% were men; their ages ranged from 42 to 87 years, with a mean age of 57 years. Patient participation was low (44%). The categories of appearance and esthetics and function were both rated at 86.2%; cost of restoration came in at 86.1%, and maintenance was rated at 71.2%.
  
  
  CONCLUSIONS
  Implant placement with simultaneous sinus augmentation was successful, and no differences were found between implants that were placed immediately and those that were delayed, which is similar to what has been found by previous studies. Patients reported being satisfied with the final cost of the implant restoration.
