Stability and marginal bone level measurements of unsplinted implants used for mandibular overdentures: a 1‐year randomized prospective clinical study comparing early and conventional loading protocols

Abstract

Although a limited number of patients were followed for 1 year only, the results of the present study indicate that early loading of two unsplinted 15 mm long implants with an overdenture does not negatively affect implant stability or marginal bone conditions when compared with implants subjected to 12 weeks of healing before loading.

Long-Term Retrospective Clinical and Radiographic Follow-up of 205 Brånemark System Mk III TiUnite Implants Submitted to Either Immediate or Delayed Loading

“…[11][12][13][14] Furthermore, a greater torque is needed to remove moderately rough-surfaced implants as compared with machined ones. [15][16][17][18][19] In 2000, implants with a highly crystalline phosphate-enriched titanium oxide layer, characterized by a microstructured surface with 1 to 10 mm pores (TiUnite; Nobel Biocare, Göteborg, Sweden), were introduced to obtain a successful and long-lasting osseointegration. 20,21 This oxidized surface has been proven to increase initial bone-to-implant contact and shown osseoconductive properties, resulting in improved maintenance of implant stability during the healing phase as compared with machined titanium implants.…”

Implant Stability and Peri‐Implant Parameters in Free Vascularized Iliac Graft Transplantation Patients: Report of Three Ameloblastoma Cases

“…Although the study by Schultes et al 21 presented the highest MMD values for iliac crest transplants, they measured the stability of implants with another device, the MMD. In the present study, we analyze the stability of implants in free vascularized iliac crest grafts by a recent, electronic device, † † and the ISQ values achieved are lower than the ISQ values reported for the mandibula by Turkyilmaz et al 44 However, all implants were stable in all cases without any stability problems. The satisfactory prosthetic treatment of patients with large tumor defects may be restored by the use of vascularized free flaps followed by the application of endoosseous dental implants.…”

“…However, in the present report, the ISQ values obtained from grafted sites are found to be slightly lower than the values obtained from dental implants in intact mandibular sites reported in the literature. 44 In a randomized prospective clinical study, Turkyilmaz et al 44 measured the primary stability of dental implants placed in anterior mandibula-supporting overdentures performed 1 week or 12 weeks after surgery. The implant stability for early and delayed loaded mandibular implants was expressed as 76.2 -2.8 and 75.6 -4.5 ISQ at implant surgery and 76.4 -2.5 and 76.4 -2.8 ISQ at 12 months, respectively.…”

Effect of melatonin on osseointegration of immediate loading implant supported mandibular over denture: Randomized clinical trail

“…These fi ndings were in accordance with . [20] Another explanation can be that the signifi cant increase in the mean bone density indicates favorable bone reaction to the applied forces that were within the physiologic limit tolerated by the bone. Moreover, the proper distribution of the load might have enhanced the structural orientation of bone trabeculae and hence increase bone density around the implants.…”
