| Abstract | ||
| Background: The class II Kennedy mandibular removable partial denture has many problems as the different nature of support as well as crossing the arch for stabilization. The Target of this work was to evaluate the changes that occurs in the supporting structures of the implants placed in class II Kennedy cases as a result of two different types of splinting materials. Materials and Methods: Thirty implants were placed in ten patients with unmodified mandibular Kennedy Class II. For each patient, three implants were placed at the premolar/molar mandibular region. All the implants were immediately loaded following an Immediate Functional Loading Protocol. Patients were divided into two equal groups; Group A: received superstructures that were splinted with acrylic resin while Group B; received superstructures that were splinted with metal. Radiographic evaluation using dental CT was carried out at intervals of 0, 6, 12 and 24 months after implant surgery. Results: The results comprised the assessment of the bone height changes surrounding the three implants placed unilaterally in the posterior mandibular areas of ten patients as a result of two different splinting materials; the acrylic resin and the chrome cobalt metal alloy. Statistical analysis showed that there was a statistically significant difference in the mean bone height values along the whole study period between both groups (P ≤ 0.05) where there was more favorable bone height values and hard tissue reaction in Group B (metal splinting) than Group A (Acrylic splinting). Conclusion: Within the limitation of this study, it can be concluded that the rigid splinting and immobilization of immediately loaded implants by metallic superstructures reduced the transmission of micro-motion to the implant bodies and improved peri-implant bone reaction in comparison with the use of the less rigid acrylic resin material. | ||
