INTRODUCTION: The primary indications for utilization of long acting local anesthetics in dentistry: lengthy dental procedures for which pulpal anesthesia in excess of 90 minutes is necessary and management of postoperative pain. Ropivacaine is a local anesthetic of the amide type that chemically is homologous to bupivacaine and mepivacaine. It is available in various concentrations and is said to have inherent vasoconstrictive properties at low concentrations. The aim of the study was to evaluate and compare the clinical efficacy of ropivacaine to lignocaine for implant surgery anaesthesia. To assess the onset and duration of anaesthesia the intraoperative and post-operative pain with both local anaesthetics and the post-operative analgesics requirement. MATERIALS AND METHODS:- 15 healthy subject with bilateral missing teeth indicated for implant placement with age range of 20 -60 years, reporting to the Department of Implantology, Rajarajeswari Dental College and Hospital, Bangalore were selected for the study. The test group involves implant surgeries in which ropivacaine was used. The control group involves implant surgeries in which lignocaine with adrenaline were used. RESULTS -The results were statistically analysed. There was a statistically significant higher duration of anesthesia for the test group as compared to the control group. Ropivacaine was found to be superior to lignocaine as far as quality of anesthesia was concerned. The comparison of mean VAS scores showed that ropivacaine has better anesthetic and analgesic effect when compared to the control group. CONCLUSION: Ropivacaine 0.75% provides significantly longer duration of anesthesia than lignocaine 2% with adrenaline.

Implant-supported restorations are often attached as screw-retained or cemented prostheses, consistent with the sort of retention. Dental implants are commonly used not just to supply patients with function but also form and esthetics. The aim of this study is to guage and compare the steadiness of peri-implant soft tissues around single implants restored with screw retained and cemented prosthesis and also to compare PES and WES for screw retained and cemented prosthesis. A total of 20 patients, both male and female with single unit implants will be selected and randomly grouped into group A and group B. Group A - 10 patients with screw retained prosthesis, Group B - 10 patients with cemented prosthesis. Evaluation of peri- implant soft tissues were analysed with photographs using PES and WES. Inferential statistics like Mann-Whitney U test and Spearman’s correlation was used. A p - value less than 0.05 was considered to be significant. PES and WES in both CP and SP groups was not statistically significant, giving an almost perfect outcome (p ≤ 0.05). Spearman’s correlation test failed to show any significant associations between the overall mean PES or WES in both CP and SP groups (p=0.65). The study demonstrated that both the restorations showed no difference and achieved favourable esthetic outcome. Keywords: Esthetic, Cemented, Screw retained, PES, WES, peri-implant
