Evaluation of Two Different Biomaterials Effect on Immediate Implant Stability and Bone Changes, a Randomized Parallel Group Clinical Trial

Abstract

How to rehabilitate the buccal gap of immediate implants is a point that confuses dentists. In this study, we aimed to compare the effect of the plasma rich fibrin(PRF) and deproteinized bovine bone mineral(DBBM) on immediate implants which have gaps wider than 2 mm in terms of stability and crestal bone change. The total number of volunteers in our study is 15. All participants have an indication of extraction on tooth which has two adjacent teeth in the maxillar anterior or premolar region and rehabilitated with immediate implants. All individuals were divided into three groups as DBBM, PRF and Control by envelope method. Stability measurements was performed separately as mesiodistal(MD) and buccolingual(BP) at 0 and 120th day. CBCTs were taken pre-op and post-op 9th month. There was no statistically significant difference between the three groups in terms of mesial/distal and horizontal crest losses, T1-T0 MD and BP changes. The use of PRF or DBBM in the buccal gap can contribute to the stability and prevents vertical and horizontal bone losses.
