What does resorbable plate and screws break down into?

• A. Calcium and Phosphorus
• B. CO2 and H2O
• C. Sodium and Chloride
• D. Potassium and Magnesium

Answer: (B)

The correct response highlights the biocompatibility and biological behavior of resorbable plates and screws used in oral and maxillofacial surgery. These materials are typically made from synthetic biodegradable polymers, such as polylactic acid (PLA) or polyglycolic acid (PGA), which are designed to be absorbed by the body over time following their function in providing support for bone healing. As these resorbable materials degrade, they undergo hydrolysis, breaking down into the simplest molecules that can be safely metabolized by the body. This process primarily produces carbon dioxide (CO2) and water (H2O), which are naturally excreted through the lungs and urinary system, respectively. This characteristic is crucial as it reduces the need for a second surgical procedure to remove hardware, minimizing patient discomfort and recovery time. While other options represent elements or compounds that are biologically relevant, they do not accurately reflect the degradation products of resorbable fixation devices. The substances in those choices do not correspond to the metabolic outcomes of the materials used in resorbable plates and screws. Therefore, CO2 and H2O is the expected and correct answer when considering the degradation of these devices in a biological context.
