Influence of Soft Tissue Thickness on the Marginal Bone Level Around Implants in Esthetic Zone: 1 Year Randomized Control Trail
Influence of Soft Tissue Thickness on the Marginal Bone Level Around Implants in Esthetic Zone: 1 Year Randomized Control Trail
Healthy soft tissue around the implant are considered as a biological seal to prevent inflammatory periimplant diseases and ensure healthy, stable and long-term survival of a dental implant. Due to the fact that the measurement methods in the literature differ, it is necessary to establish objective measurement method and to determine the minimum amount of tissue thickness to maintain a stable level of bone around the implant.

Purpose:
The aim of the study was to determine the effect of soft tissues in the implant area on the marginal bone level loss in the implant area and to define of the critical gingival thickness to minimize marginal bone level (MBL) loss.
Materials and methods:
75 bone level implants (Conelog® Camlog, Switzerland) were inserted in the aesthetic area. Thickening of soft tissues was performed both before and after implantation (group II and III), CTG and XCM were used (subgroup a and b). 12 months after the loading with final restoration, the thickness of soft tissues in the implant area was examined with ultrasonography (USG) device (Pirop®, Echoson, Poland), and each implant was subjected to Radiovisiography (RVG) RVG examination, where MBL loss was determined.
Inclusion Criteria:
To qualify for the study, the patients had to be >18 years and have missing teeth in the esthetic zone. Additional inclusion criteria were as follows:
Exclusion Criteria:
The criteria that disqualified patients from the study were previous grafting procedures in the area of interest and systemic or local diseases that could compromise healing or osteointegration. Smokers and patients with bruxism were also excluded from the study. Additional exclusion criteria were as follows:
