| Abstract | ||
| Rehabilitation of single edentulous maxillary arches with screw-retained prostheses is considered an optimal treatment choice. However, atrophy in the maxillary may result in deficient bone volume for implants. The “All-on-4” concept offers favorable clinical results for immediate rehabilitation. Primary stability is essential for efficient immediate loading. Different osteotomy procedures were proposed for preparation of the implant site. Osseodensification is used to improve quality of bone and initial stability. Aim of the study: To compare and evaluate the effect of osseodensification versus self-tapping technique on immediately loaded maxillary fixed-detachable restorations retained by implants inserted according to the all-on-four concept. Materials and methods: Twelve patients with maxillary posterior atrophy, received screw-retained restorations retained by implants placed following the all–on-four concept. Split mouth design was conducted whereas each patient received two implants inserted following the osseodensification technique and two utilizing the self-tapping technique followed by immediate loading. Primary stability was evaluated immediately after surgery and 12 months. Radiographical evaluation of alveolar bone loss was evaluated using (CBCT), at insertion, 6 months and 12 months later. Results: For primary stability the highest mean values were recorded in the osseodensified side, while higher amounts of bone loss were measured at the self-tapping side, revealing statistical significance between both groups. | ||
