简要总结
i) Rationale:
Peri-implantitis can be defined as a crestal bone loss / marginal bone loss (MBL) equal to or greater than three millimeters in the presence of clinical signs such as PPD > 6 mm and BOP.Although MBL does not always lead to peri-implantitis, there is no peri-implantitis without the prior presence of MBL. Berglundh et al. has related this to thickness of soft tissues. They reported that in thin tissues formation of gingival cuff after the second stage surgery resulted in significant bone resorption, in contrast to the thick tissue group, where no statistically reliable bone loss occurred. Hence, it seems that correlation between the thickness of gingival tissue and subsequent bone loss around implants does exist.
ii) Novelty:
Assesment in mucosal tissue thickness classification given by Egreja et al in 2012. Marginal bone loss will be measured using CBCT in SIDEXIS 4 software with SICATSUITE version 2.0. (Dentsp ly Sirona; York, US) immediately after implant placement and 6 months later.
iii) Objectives:
To evaluate and compare the MBL around the implants placed in thin and thick mucosal tissue.
iv) Methods:
The mucosal tissue thickness will be assessed with transgingival probing method given by Dimitrios Kloukos et al in 2021.Radiographic assessments for MBL around the implant will be done immediately after implant placement, 6 months and 12 months later using CBCT. MBL will be measured using SIDEXIS 4 software with SICATSUITE version 2.0. (Dentsply Sirona; York, US)
v) Expected outcome:
Less marginal bone loss in thick mucosal tissue as compared to thin mucosal tissue.
Hypothesis:
In thin and thick mucosal tissue there might be marginal bone loss or no marginal bone loss around the implant
