Background Nowadays implant-retained overdentures retained by bar attachment are used on a wide scale as a substitute for the conventional complete denture thus further studies are required to verify this replacement.
Methodology Fourteen completely edentulous patients were randomly categorized into two equal groups. In the control group (Group I) patients received implant-retained overdentures retained by bar attachment with retentive plastic clips, while in the test group (Group II) patients received implant-retained overdentures retained by bar attachment with retentive clips made of Poly Ether Ketone Ketone(PEKK) material. All the patients were scheduled for recall visits and probing depth was recorded at the time of loading, six months, and twelve months.
Results: Regarding probing depth: (Group I) was significantly higher than (Group II) after 6 and 12 months. Data were coded and entered using the statistical package for the Social Sciences (SPSS) version 28 (IBM Corp., Armonk, NY, USA). Data were summarized using mean and standard deviation. Comparisons between groups were done using an unpaired t-test. Comparison over time within the same group was done using paired t-test. P-values less than 0.05 were considered statistically significant.
Conclusion: Within the limitations of this study, Implant retained overdentures retained by bar attachment with plastic retentive clip material are less recommended than implant-retained overdentures retained by bar attachment with PEKK retentive clip material.
