AbstractBackground: The implant can be placed either immediately after the tooth extraction (Immediate) or 15 days after the tooth extraction (Delayed immediate). The purpose of this study is to evaluate the width of keratinized gingiva, thickness of peri-implant mucosa, height of interproximal papilla, probing depth, soft tissue condition and bone loss around the single tooth implants. These parameters were compared clinically and radiologically between immediate and delayed single tooth implant techniques.
Material & Methods: A randomized, prospective clinical trial was conducted to evaluate the clinical and radiological parameters of immediate and delayed single tooth implant placement at department of periodontis at Rajasthan Dental College & Hospital, Jaipur, Rajasthan. 20 (ten females, ten males) patients of both sexes with an age limit of 20-40 years were selected for the study. The single tooth implant sites were randomly selected in either the upper or lower jaw, irrespective of whether it was an anterior or posterior region. The selected patients were categorized into two groups based on immediate and delayed implant placement protocols. Assessment of soft tissues at the implant site was performed after crown cementation at baseline, 9 & 18 month by single examiner. At the follow up visits, the following parameters were assessed, width of keratinized gingiva, thickness of peri-implant mucosa, height of interproximal papilla, probing depth, soft tissue condition and bone loss around the single tooth implants.
Results: In percentage, the Width of keratinized gingiva(loss), thickness of peri-implant mucosa(gain), papilla index (gain) and Peri-implant bone loss(loss) in immediate group showed 5.7% reduction, 24.17% gain, 10.90% gain & 13.43% loss respectively and in delayedgroupitwas8.57%, 25.88% gain, 10.76% gain & 15.60 % loss respectively at18th months.The percentage of probing depth reduction in mesially, distally, buccally, and lingually at 9 months & 18 months in immediate & delayed implant was statistical non-significant.
Conclusion: We concluded that self-threaded internal hex, titanium implants placed according to a delayed or immediate technique can be used successfully over a period of 12months. High successful rates were achieved without severe peri-implant complications
