Abstract

Aim: This Randomized Double-Blinded Control Clinical Trial aims to assess the effect of 3D Printed Digital versus Acrylic Resin Conventional Occlusal Stabilization Splints on the Marginal Bone height around Implants installed in Mandibular Class I Kennedy Patients diagnosed with Sleep-Related Bruxism.

Material and Methods: Twelve patients were examined and diagnosed with sleep-related bruxism and with unmodified mandibular Kennedy Class I was recruited in this study. For each patient, three implants were placed bilaterally in the premolar/molar mandibular region. Patients were divided into two groups: Group I (Six patients) received 3D Printed Digital occlusal stabilization splints and Group II (Six patients) received the conventional acrylic stabilization splints on the day of restoration insertion. Cone beam computed tomography (CBCT) was used to examine the radiographic assessment at 0, 3, and 6 months after surgery. All data were investigated for normality by using Shapiro Wilk and Kolmogorov Normality test and presented as mean difference and standard deviation (SD) values then statistically analyzed. The significance level was set at P ≤ 0.05.

Results: This study showed a non-statistically significant difference in bone height in the two groups (P > 0.05) throughout the whole study period.

Conclusion: Both the 3D Printed Digital Splints and the Conventional Acrylic Stabilization Splints showed reliable results on bone height changes around implants and either types should be advised to be worn for protecting the underlying fixed implant prosthesis and supporting structures in patients diagnosed with sleep related bruxism.
