Assessment of crestal bone loss surrounding dental implants using CBCT in different tissue biotypes

Marginal bone loss (MBL) is a crucial marker of implant health. Hence this study was done to assess the amount of height of crestal bone lost surrounding dental implants positioned in different tissue types. Twenty six patients with single edentulous areas were divided into two groups at random with 13 samples in each group .Groups A and B comprise implants placed in thick tissue biotypes and thin tissue biotypes, respectively. Cone beam computed tomography (CBCT) was done in both groups at baseline and after implant placement to evaluate the loss of crestal bone surrounding the distal and mesial sides of the implants. Before occlusal loading, at the moment of cementation, a follow-up CBCT was taken. During the time of cementation, both groups experienced a discernible loss of crestal bone on the mesial and distal sides of the implants; however, group B shows a larger loss of crestal bone than group A. Compared to Group A (thick tissue biotype), Group B (thin tissue biotype) had a greater mean crestal bone loss. During the peri-implant healing period, crestal bone alterations are less common in thick biotypes than thin biotypes.
