Abstract Aims: to compare accuracy of selective laser sintered computer guided stents versus digital light processing stents in immediate implant placement in esthetic zone. Settings and Design: : the present study was a randomized clinical trial Methods and Material: the patients were recruited according to the eligibility criterias. The recruited patients were randomly allocated to either digital light processing stents (test group) or selective laser sintered computer guided stents (control group). Planning and construction of tooth supported computer guided surgical stent was done by either digital light processing technique for test group or selective laser sintering for control group. Total 20 implants were immediately computer guided inserted after atraumatic extraction in both groups. The accuracy of implant placement was measured in terms of both linear and angular deviation of the placed implant from planned one. Statistical analysis used: Tests were considered statistically significant if the p- value was less than 0.05. Difference in means were calculated for the analysis of continuous variables with corresponding 95% confidence intervals Results: there was no statistical difference between selective laser sintering and digital light processing groups in all measured terms. Conclusions: Within the limitations of this study (sample size), Any of the two techniques can be used for immediate implant placement with clinically satisfactory results.
