Immediate Versus Delayed Dental Implants

Objective: The main aim of this study was to compare immediate and delayed implants for the placement and postoperative assessment. For this purpose, dental implant were placed using the set criteria and patients were recalled for follow up for postoperative assessment.

Methods: This is a clinical study comparing the outcome of immediate placement versus delayed placement of Osseointegrated dental implants. Patients were divided in to two study groups (Group I and Group II) using the set criteria. Group I (n=12) Immediate Dental Implant and Group II (n=12) Delayed Dental Implant All patients were assessed preoperatively for complete medical and dental history and clinical examination. Surgically placement of dental implant was performed under local anesthesia. Patients were recalled for postoperative follow up for six month.

Results: Implant mobility was not reported in any case under investigation during the follow up period. Bone loss was higher in Group II at all the instances. For group I bone loss was 0.24±0.26 mm, 0.18±0.16 mm, 0.08±0.09 mm for 1st, 2nd, and 3rd weeks respectively. The higher bone loss ~0.5 mm/week was observed for the same period in group II patients. Regarding pain assessment, at 1 week, in both the groups the mean pain score was 0.63, at 2nd week in Group I the pain score was 0.13±0.35 while in Group II it was 0.06±0.25.

Conclusion: Immediate and delayed dental implants provide excellent stability. Immediate type of implantations was comparatively better in controlling the peri-implant radiolucency, postoperative infection and inflammation. Excessive bone drilling required for delayed implants result in exaggerated bone reaction and leading to higher rate of bone resorption.
