Abstract
This study was made to evaluate tissue health changes around immediately loaded; splinted and free standing; implants used to retain mandibular complete overdenture. Material and methods: A standardized size of 16 mm length and 3.25 mm width; titanium self tapping implant fixtures were selected for all cases. A conventional complete denture was constructed with monoplane artificial acrylic resin teeth. Patients were equally divided into two groups: Group I (Free standing implants): using ball attachment to retain complete mandibular overdenture. Group II (Splinted implants): splinted with bar attachment (bar joint) to retain complete mandibular overdenture. All clinical examinations and data collections were performed immediately, after six and 12 months of implant loading. Marginal bone loss, peri-implant probing depth, bleeding index and plaque index and implant mobility were recorded using standard scores. Results of this study revealed that the higher marginal bone loss was observed around free standing implants compared with splinted implants. There was a statistically insignificant difference in the mean probing depth and bleeding index within and between both groups in all periods of this study. There was a statistically significant plaque accumulation around splinted implants compared with free standing implants. Mobility index measured in this study showed zero score during all periods of this study in both groups. Conclusion: Splinting of immediately loaded implants with mandibular overdenture is recommended for healthier supporting structure around the implants. Immediate implant loading with mandibular overdenture can be considered as a successful prosthetic approach for completely edentulous patients.
