 Patients in the one-stage group will receive a temporary acrylic crown manufactured chair-side at the same visit. Care will be taken to relieve the crown from occlusal and laterotrusive contacts. The distance from the soft tissue margin to the occlusal stent will be measured using a periodontal probe at six sites around the implant mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual and distolingual at the time of post-surgical follow-up, 1-2 weeks after surgery.
