Conical Biosilicate Implant for Volume Augmentation in Anophthalmic Sockets

Anophthalmic socket reconstruction remains a clinical challenge. Current implants lack ideal properties for long-term success. Prior research has shown that conical implants improve volume retention compared to spherical designs. Biosilicate, a bioactive glass-ceramic, has demonstrated favorable integration in animal studies. However, human trials remain limited. The need for a material that integrates well and avoids extrusion is unmet. Existing options like porous polyethylene have known limitations. This gap motivated the investigation of Biosilicate implants in human patients.

This study aimed to evaluate a new conical implant made of Biosilicate for orbital volume augmentation. The specific problem addressed is the lack of durable, well-integrated implants for anophthalmic sockets. The motivation stems from animal trials showing promising results with Biosilicate. The study sought to compare this new material to polymethylmethacrylate implants. Researchers wanted to assess clinical outcomes and implant stability. They focused on infection rates and positioning accuracy. The goal was to determine if Biosilicate could offer a viable alternative to current materials. The study design aimed to provide evidence for clinical adoption.

The study used a prospective, randomized design with 45 participants. Patients received either Biosilicate or polymethylmethacrylate conical implants. Clinical evaluations occurred at multiple time points post-implantation. Systemic assessments included laboratory tests and imaging. Computed tomography scans checked implant positioning. Infection and inflammation markers were monitored. Data collection spanned 180 days after surgery. Outcomes were compared between the two groups using statistical analysis.

Both implant types showed good clinical outcomes with no major complications. Only one case of early implant extrusion occurred in the Biosilicate group. Laboratory tests remained normal in both groups. Computed tomography confirmed proper implant positioning. No significant inflammatory processes were observed. The success rate exceeded expectations for both materials. The Biosilicate implant demonstrated comparable performance to the control. These findings suggest Biosilicate is a viable alternative material.

The Biosilicate conical implant performed well in anophthalmic socket reconstruction. The authors propose that this material could replace porous polyethylene implants. The study suggests Biosilicate implants may offer similar outcomes to current options. The absence of significant complications supports its use. The single case of extrusion does not outweigh the benefits observed. The researchers conclude that Biosilicate is a promising alternative. They emphasize the need for further studies on long-term outcomes. The findings suggest this implant could become a standard option.
