Background:
Thick keratinized tissue around implants is an important factor in crestal bone change.
Aim/Hypothesis:
The aim of this study was to evaluate crestal bone changes around bone and tissue level implants in relation to initial mucosal thickness.
Material and Methods:
Patients were referred for implant placement and received a minimum of 2 implants: an implant with the prosthetic abutment connection at the crestal bone level (MC) and with the prosthetic abutment connection 2,5 mm supra crestal (LC). The patients were divided into 2 groups according to their initial mucosal thickness. Group A; 2mm or less and group B more than 2mm.
Results:
Group A_MC consisted of 17 implants with a mean loss of -0.6 ± 0.1 mm. Group B_MC of 20 implants with a mean loss of -0.2 ± 0.1 mm. Group A_LC of 15 implants with a mean loss of -0.1 ± 0.1 mm. Group B_LC of 22 implants with a mean loss of -0.2 mm ± 0.1 mm. Group A_MC and group B_MC showed a statistical significant difference (p = .003). Group A_LC and group B_LC showed no statistical significant difference (p = .518).
Conclusions and clinical implications:
If the initial mucosal thickness surrounding bone level implants is more than 2 mm there is statistical significant less crestal bone change when compared to bone level implants placed in initial mucosal thickness of 2mm or less. This difference is not statistical when tissue level implants are used and the implant abutment connection is 2.5 mm above the crestal bone level.
