Objectives
The aim of the study was to show the relationship between the use of static navigation when placing dental implants and maintaining the bone level in the area of the implant platform.
Materials and Methods
The study included a group of 20 patients (10 women and 10 men) aged 27-61, generally healthy, without any accompanying systemic diseases and with good bone conditions not requiring additional augmentation procedures.
Digital planning method was used and implantation of titanium dental implants using static navigation was performed with a surgical guide. During the first surgical stage, after placing the implant, a digital X-ray was taken using the right-angle technique. During the second stage of surgical treatment, after 3 months in the case of mandible and 6 months in the case of maxilla, the implants were uncovered to check osseointegration and replace the closing screws with healing screws. A digital X-ray was also taken at this stage.
Digital X-rays from the day of surgery and the day of implant uncovering were analyzed. The degree of atrophy was defined as the difference in marginal bone level measured in millimeters.
The data were subjected to statistical analysis.
Results
In 17 patients, the marginal bone level did not change after the osseointergation period. In one patient there was a 1 mm atrophy, while in two patients there was a 0,5 mm bone apposition in the area of the implant platform.
Conclusions
The usage of static navigation has a positive effect on the marginal bone level around an implant. The research results may help to develop an effective algorithms affecting the osseointegration process and a stable final treatment result.
