vendex and Periodontitis

To compare peri-implant bone and soft-tissue levels of immediately non-occlusally loaded versus non-submerged early loaded implants in partially edentulous patients 5 years after implant placement.. Fifty-two patients were randomised in five Italian private practices: 25 in the immediately loaded group and 27 in the early loaded group. To be immediately loaded, single implants had to be inserted with a torque of > 30 Ncm, and splinted implants with a torque of > 20 Ncm. Immediately loaded implants were provided with non-occluding temporary restorations within 48 hours. After 2 months, the provisional restorations were put in full occlusion. Implants were early loaded after 2 months. Final restorations were provided 8 months after implant placement. Outcome measures were prosthesis and implant failures as well as biological and prosthetic complications recorded by non-blinded assessors. Blinded assessors evaluated peri-implant bone and soft-tissue levels.. Fifty-two implants were immediately loaded and 52 early loaded. One patient of the early loaded group dropped out after the 1-year recall. One single immediately loaded implant failed 2 months after placement. Only one complication (iatrogenic peri-implantitis) occurred in one patient of the early loading group. Both groups gradually lost peri-implant bone in a highly statistically significant way at 2, 8 and 14 months and at 4 and 5 years. After 5 years, patients of both groups had lost an average of 1.2 mm of peri-implant marginal bone. There were no statistically significant differences in peri-implant bone and soft-tissue level changes between the 2 groups. At 5 years, there was a statistically significant recession (0.2 mm) of the vestibular soft tissues from baseline (delivery of the final restorations 8 months after implant placement) only for immediately loaded implants.. In well maintained patients, complications are uncommon and healthy and stable periimplant tissues can be maintained for 5 years around immediately and early loaded implants.

To evaluate the efficacy of 7-mm-long flapless placed single implants immediately or early loaded at 6 weeks.. Thirty patients received two single Nanotite External Hex Biomet 3i implants that were then randomised for immediate or early loading. All implants had to be inserted with a minimum torque >40Ncm. Provisional crowns were put in slight occlusal contact and replaced by definitive crowns 3 months after loading. Outcome measures were implant failures, biological and biomechanical complications, peri-implant marginal bone level changes and patient preference.. Twenty-nine implants were immediately loaded and 31 early loaded. Thirteen flaps had to be elevated in 12 patients. Eleven implants in ten patients did not reach the planned insertion torque. Eight implants in seven patients were immediately replaced by implants with a larger diameter, two were loaded anyway, and one implant that was randomised to immediate loading was early loaded instead. Nine months after loading, no drop-out occurred. One implant failed in each group. There were no statistically significant differences between groups for implant losses, complications, mean marginal bone level changes, and patient preferences.. Flapless placed 7-mm-long single implants can be successfully loaded the day of insertion. Longer follow-ups are needed to monitor the long-term prognosis of short implants.
