Abstract
Aim: Assess the accuracy of implant placement using a mucosa-supported surgical guide relative to the planned implant position and examine patient-related outcomes associated with immediately-loaded Mx IOD using a single-attachment abutment system. The secondary aim of the study is to examine the prosthetic complications associated with this treatment.
Materials and methods: Fifteen individuals with edentulous maxillae were included. Each participant received 4 Straumann BLX implants through a stereolithic mucosa-supported surgical guide distributed in the Mx arch to maximize AP spread. Implant lengths ranged from 10 to 14 mm. A post-op CBCT was taken after the surgery to compare the accuracy of the implant placement with the planned position using the Treatment Evaluation Module in CoDiagnostix. Primary outcome variables were 3D offset at apex and platform along with global angular deviation and patient-related outcomes.
Results: Fifteen participants had 60 implants placed. Fifty-nine of those implants were suitable for assessment. The mean global deviation of the implants was 3.28±1.929º, the 3D offset of the implants was 0.86±0.484 mm at the platform and 1.036±0.59 mm at the apex. Statistically significant higher 3D offset was observed for the implant platform and apex between posterior and anterior implants at 0.762 vs. 0.984 and 0.862 vs. 1.203 mm respectively.
Conclusion: The accuracy of mucosa-supported surgical guides for Mx IODs is within the acceptable range of error when compared to planned position. Posterior implants show greater deviation than anterior implants. Patient-related outcomes improve immediately after the prosthesis is loaded and continue to improve over the follow-up period.
