Objectives
Complex, three-dimensional bony defects still represent challenging situations in routine implant dentistry. The aim of this study was to evaluate implant survival in customized bone regeneration using a patient-specific titanium mesh.
Material and Methods
Patients (n = 21, implants 36) who had obtained an augmentation procedure with patient-specific titanium mesh were examined after 5.7 ± 0.38 years. Survival rate, clinical parameters for periimplantitis (Bleeding on Probing [BOP] and suppuration), and radiographic examination were evaluated. Peri-implant marginal bone loss (MBL) was calculated by using an image assessment program. Additionally, the influence of various factors on treatment outcomes such as periodontitis, smoking, professional maintenance, or diabetes was assessed as well as the impact on quality of life applying the Oral Health Impact Profile (OHIP).
Results
The implant survival rate was 97%, with one implant loss in the lower jaw. At the end of the observation period, MBL showed mesial 0.13 ± 1.84 mm and distal −0.13 ± 1.73 mm. The lower jaw showed significant more MBL mesial compared with the upper jaw (p = .034, cluster-adjusted). Periodontitis was significantly associated with MBL mesial and distal (p < .05). Positive BOP (four implants) was significantly associated with MBL mesial (p = .0031) and distal (p = .0018). MBL was significantly associated with suppuration mesial (p < .0001) and distal (p < .0001).
Conclusions
CBR® results in high implant survival rate and stabilized augmented marginal bone after follow-up of minimum 5 years. Periodontitis seems to play the mayor role for long-term stability indicated by BOP and suppuration.
