| Abstract | ||||
| Background: New types of reinforcement materials are currently used on wide scales to reinforce implant-retained overdentures as a substitute for conventionally non-reinforced overdentures; thus, further studies are needed to validate these materials. Methodology: Fourteen edentulous male patients received 4 mini implants, in the anterior part of the mandible using the flapless surgical approach. Group I received seven mandibular implants retained overdenture reinforced with cobalt chromium(CoCr) meshwork while Group I received seven mandibular implants retained overdenture reinforced with poly-ether ketone(PEKK) meshwork, marginal bone loss was measured at the time of denture insertion, 6 months, and 12 months, The mesial buccal, distal buccal, mesial lingual, distal lingual, mid-buccal and mid-lingual marginal bone heights around the implants were evaluated, using the linear measurement system of the software with flat panel detector supplied by the cone beam computed tomography(CBCT) as well as patient satisfaction after 6 months of denture insertion by using a questionnaire to know their level of satisfaction. Results: Regarding marginal bone loss: after 6 and 12 months (Group I) shows more bone loss than (Group II), but in patient satisfaction, it was found that there is no difference in patient satisfaction in both groups in the first part and second part of questions in the questionnaire and patients of both groups were satisfied with their denture. Conclusion: (PEKK) meshwork reinforcement material provided less bone loss after 6 months and 12 months when compared with CoCr. meshwork reinforcement material while patient satisfaction in both groups was the same | ||||
