6-Month Retrospective Cohort Study On Periodontal Indicators in Immediately Placed and Delayed Implants Following Prosthesis Delivery

Abstract

Replacing teeth with implants is one of the remarkable developments in dentistry. The studies carried out in the fieldof implants focus more on soft and hard tissue, and the comparison of immediate and delayed implants has received less attention.The presence or absence of periodontal indicators around immediate and delayed implants to maintain their health and long-termpresence is a matter of discussion. This study aimed to investigate periodontal indicators in implants placed by delayed andimmediate methods six months after delivery of the prosthesis. In this retrospective cohort intervention, 50 patients with implants(25 immediate implants and 25 delayed implants) who were selected from dental clinics in Ilam, Iran, were studied. Measurementswere conducted by the examiner using a periodontal probe. The examined items included implant location, implant type(immediate or delayed), bleeding on probing (BOP) around the implant, probing depth (PD) around the implant, and WKG aroundthe implant. The collected data were analyzed using a t-test and Chi-square test. The average PD around the implant after 6months of placement in the immediate implant group was significantly increased (P<0.01) compared to that of the delayed implantgroup. Also, the results of the present study showed that patients with delayed implants experience more BOP around the implant(P<0.01) compared to patients with immediate implants. The present study showed that delayed implantation after 6 months is asuccessful treatment process and effectively reduces the treatment time.
