| Abstract | ||||
| Purpose: This study was performed to evaluate the effect of PEEK reinforced mandibular implant overdenture, in comparison with metal reinforced mandibular implant overdenture on bone height. Subjects and methods: Fourteen completely edentulous patients were selected with ages ranging from 50-70 years. All the patients received two implants in the inter-foraminal area of the mandible and maxillary complete dentures, then they were divided into two groups: group (I) seven patients received PEEK reinforced mandibular implant overdentures, group (II) seven patients received metal reinforced mandibular implant overdentures. The overdentures were functionally loaded after three months of implant insertion and retained with the implants using ball and socket attachments. Evaluation of crestal bone height changes around the implants and in the distal aspect of the ridge was done by CBCT at the time of denture insertion, 6 and 12 months. Results: The results revealed that there was a statistically significant decrease in amount of crestal bone loss in PEEK group than in metal group after 6 and 12 months. The results also showed that, there was non significant difference when comparing the changes in the distal bone height after 6 months then, there was a statistically significant decrease in amount of distal bone loss in PEEK group than in metal group after 12 months. Conclusion: PEEK reinforced implant overdentures have better results than those reinforced with metal, as they recorded favorable radiographic outcomes after one year of overdenture insertion regarding crestal and distal bone height changes. | ||||
