Abstract
This study was conducted to evaluate the peri-implant bone loss around platform switching and non platform switching implants. The study was designed as a randomized controlled split mouth clinical trial for a period of 12 months. The study population comprised of 10 subjects and 20 sites. Group A consists of 10 sites, in which non platform switching implants was placed (Control sites) and Group B consists of 10 sites, in which platform switching implants was placed (Test sites). Clinical parameters such as width of keratinized gingiva, thickness of the peri-implant mucosa, papilla index, soft tissue index, probing pocket depth were evaluated. Radiographic evaluation of peri-implant bone loss was also analyzed. AIMS AND OBJECTIVES: 1. To assess if any significant correlations exists between the width of keratinized mucosa, thickness of the peri-implant mucosa, papilla index, soft tissue index, probing pocket depth around platform and non platform switching implants. 2. To evaluate and compare peri-implant bone loss around platform and non platform switching implants. MATERIALS AND METHODS: This study was designed and conducted by the Department of Periodontics, JKKN Dental College and Hospital, Komarapalayam, to evaluate clinically and radiographically the peri-implant bone loss around platform switching and non platform switching implants. This study was designed as a randomized controlled split-mouth trial. Ten patients with bilaterally missing mandibular posteriors to be restored with implant supported single crowns, were consecutively enrolled. A coin toss was utilized to randomize the implant placed in the patient. A total of 20 implants were placed. The test implants were integrated with a concept of platform switching and control implants with non platform switching design. Peri-implant crestal bone levels were standardized by radiovisiography prior to surgery. Implants were purchased from Norris implant (Norris Medical Ltd. Headquarters and R&D center, Israel) and the trade name for platform switching is Tuff TT implants and non-platform switching is Tuff implants. RESULTS: Platform switching seems to reduce peri-implant crestal bone resorption and increase the long-term predictability of implant therapy. The width of keratinized gingiva, the probing pocket depth and Soft tissue index in platform switching showed statistically significant difference when compared to non platform switching. The thickness of peri-implant mucosa and Papilla index showed no statistically significant difference between the groups. CONCLUSION: Based on the results obtained from the present study there was a minute refinement in clinical parameters, with a marked reduction in the peri-implant bone loss when platform switching implants were placed compared to the traditional non platform switching implants.
