Background: Different implant placement and loading protocols have been described for rehabilitation with varying rates of success and survival. This study was designed aimed to compare the success rates of implants placed to substitute maxillary incisors, canines and premolars following immediate or delayed implant placement protocol and subjected to immediate non-functional loaded single tooth.
Materials and Methods: 30 patients (male or female), in the age group of 18-45 years selected based on the inclusion and exclusion criteria. Two treatment protocols were formulated.
Protocol A: Immediately placed implants with immediate non-functional loading.
Protocol B: Delayed placement with immediate non-functional loading.
60 implants were placed; 30 following each protocol. Success rates were measured clinically in terms of implant stability (ISQ) using RFA and crestal bone loss radiographically using CBCT at timelines of 02 weeks, 01 month, 06 months and 12 months.
Inter-group statistical comparison was done using Chi-Square test and independent sample t test. The intra-group statistical comparison was done using repeated measures analysis of variance (RMANOVA). P-values less than 0.05 were considered statistically significant. Data was analyzed using SPSS (ver 21.0, IBM Corporation, USA) for MS Windows.
Results: Higher ISQ values and significant bone loss was observed when compared to baseline values in both the groups at 12 months follow up with (p<0>
Conclusion: Time dependant and comparable amount of bone loss around implants and gradual improvement in implant stability in both groups suggest immediate implant placement to be an effective option with reduced treatment period.
