A Comparative Evaluation of Soft Tissue Changes Around Two Piece Delayed Loaded Implant in One Stage versus Two Stage Implant Surgery Procedure: A Clinico-Radiographic in Vivo Study

Abstract Statement of problem: Various studies have been conducted to compare the soft-tissue changes between one-stage and two-stage implant surgery procedure but the relation of soft tissue and aesthetics with the type of surgical procedure is yet to be studied. Purpose of study: The purpose of the present study was to evaluate the soft-tissue changes around one-stage versus two-stage implants both radiographically and clinically to assess the success of implants. Material and methods: Twenty edentulous sites for implant placement were selected from patients in the age range of 18- 51 years. They were randomly assigned to two equally sized groups respectively for one-stage and two-stage implant surgery procedure. After placement of implants, all the sites were evaluated for soft-tissue outcome using standardized indices. Patient satisfaction was analyzed using visual analog scale (VAS) and aesthetic outcome was observed by 3 blind observers. All the follow ups were done after implant placement (T0), at 3 months (T1) and 6 months after loading (T2). Any changes in soft tissue dimensions were also assessed on CBCT with the help of a prepared stent. Results: The collected experimental datasets were compared between one-stage and two-stage implant surgical procedures. Inter-group comparisons of One-stage Vs Two-stage implant surgical procedure among the variables showed a non-significant result. Patient Compliance scores and Aesthetic outcome by blind observers also showed non-significant differences. Conclusions: Within the limitations of the study, it was concluded that there were no significant differences with respect to soft-tissue outcome, patient compliance and aesthetic outcome
