Immediate or Delayed Provisionalization in Posterior Healed Sites

In this study, the investigators will examine the performance of a new dental implant that has been approved by the Food and Drug Administration for use to replace of missing teeth. The investigators will study two groups of patients: one group will receive a temporary crown to replace the missing tooth at the same day as implant surgery; the second group will receive a similar crown 3 months later. Both groups will receive a permanent crown on the implant 4 months after surgery, and will be followed up for a period of 12 months. The investigators want to examine whether the healing of the bone and gums surrounding the implant that receives a crown immediately is similar to the healing of the implant when the crown is delivered later. If this is indeed the case, then the investigators will be able to recommend faster treatment for all patients.
