ABSTRACT
The Premature Loss Of Primary Teeth Is Considered A Major Challenge That Encounters Normal Occlusal Development In Pediatric Dentistry. Space Maintainers Are Exceedingly Reliable Maneuvers Used To Preserve The Space For The Succedaneous Dentition. Survival Of Space Maintainers Has Gained The Interest Of Researchers In Pediatric Dentistry, Due To Their Clinical Importance In Developing Normal Occlusion In Pediatric Population. However, Multiple Factors Can Affect The Efficacy Of The Space Maintenance Through Its Effect On Tooth Structure And Gingival Health. The Aim Of The Study Is To Assess Mean Survival Time, Gingival Condition And Caries Status Of Chairside Band And Loop Space Maintainers Compared To Conventional Band And Loop Space Maintainer. Clinical Trial Conducted On Thirty Healthy Children Between Ages Four To Seven Years Old With Premature Loss Of Bilateral Mandibular Primary First Molars Were Selected From Pedodontic Clinic, Faculty Of Dentistry, Tanta University. For Each Candidate, Chairside Space Maintainer Was Inserted In One Side, While The Conventional Type On The Other Side And Evaluated Every 3 Months For Nine Months. The Mean Survival Time Was 8.56 Months In Chairside Space Maintainer And 7.5 Months The Conventional Type. No Statistical Significant Difference (P>0.05) Between Both Groups Regarding Success Rate, Survival Time, Caries Assessment, Only Gingival Index Increased During Study Period. In Conclusion: Chairside Space Maintainer Is Considered A Successful Appliance.
