| Aim of the study: to compare complete denture with implant supported overdenture regarding occlusion and disocclusion time using a T scan. Materials and methods: A crossover clinical trial was adopted,50 patients were selected for this study. The assessment was carried out with conventional complete dentures and then with the same dentures after loading of the implants. Computerized occlusal analysis using the T-Scan III system was conducted to perform baseline computer-guided occlusal adjustment for conventionally fabricated dentures. Recording of OT (occlusion time) and DT (Disocclusion time) right and left values using the T-Scan were subsequently carried out for all dentures, first without implants and then after implants loading. All T-Scan procedures were carried out by the same clinician. Results: Independent t test was used in this study because data was normally distributed. The OT values were recorded and a mean OT value was calculated for each subject, where the CD Complete denture group mean OT (0.49±(0.21)s which was about 0.13 s longer than the Implant Supported Over Denture(ISOD) mean OT (0.36±(0.19). The disocclusion time were for right 0.55± 0.25 for CD and 0.35± 0.32 for ISOVD, while on the left was 0.56±0.24 for CD and 0.37±0.27 for ISOVD. There were highly significant results between the two groups in Occlusion time and disocclusion RT and left 0.0016, 0.0007, 0.0003 respectively. Conclusion: Using the computerized analysis of the Occlusion Time, Implant supported over denture proved to be a better treatment option regarding occlusion and disocclusion time where timing decreased significantly after implant loading. | ||||
