• What decisions are you making as the activity progresses regarding the selection of alloplastic materials and their biocompatibility for this specific case?
• Which aspects of interpreting multimodal imaging (e.g., CT or MRI data) feel intuitive to you, and which parts require more conscious effort to ensure a safe clinical standard is maintained?
• How are you ensuring that your manufacturing steps align with the principles of the Quality Management System (QMS) used in your professional practice?

How are you progressing with the activity?

• How effective are your design actions in achieving a precise fit for the implant, and what challenges are you encountering during the manufacturing process?
• What are you learning about the clinical application of laboratory work as you observe the surgical team fitting the device in the operating theatre?
• How does the real-time observation of the surgical procedure connect to your existing skills in patient-centred care and service governance?
• Are you identifying any barriers to successful implantation while watching the MDT work, and how does this influence your understanding of the patient’s care pathway?

How are you adapting to the situation?

• If the surgical team encounters difficulties during the fitting, what alternative design or material approaches are you considering in the moment for future cases?
• How are you ensuring that your presence and communication within the operating theatre remain strictly within your scope of practice and regulatory requirements?
• What immediate support or guidance do you need from the surgeon or your Training Officer to better understand the intra-operative challenges of alloplastic implants?
• How are you adapting your communication style to effectively interact with various clinical specialisms within the MDT as the situation in the theatre unfolds?

On action

What did you notice?

• How would you summarise the key procedural elements of the experience, from the initial analysis of multimodal imaging to the final manufacturing and observation of the implant fitting in theatre?
• What specific actions or interactions during the surgical observation felt most significant in understanding the relationship between laboratory design and clinical application?
• How did you feel about your contribution to the multidisciplinary team (MDT) while observing the fitting, and did it change your perspective on the roles of the surgeon and theatre staff?
• Did you notice any moments where your reflection-in-action (decisions made during the design or manufacturing phase) directly influenced the ease or difficulty of the intra-operative fitting?

What did you learn from the activity?

• What specific knowledge have you gained regarding the clinical performance and properties of alloplastic materials, such as their biocompatibility and stability when integrated into a cranial defect?
• How has this activity improved your technical proficiency in using CAD/CAM planning and advanced manufacturing techniques to meet a safe clinical standard?
• What did you learn about the Quality Management System (QMS) protocols required when producing a custom implant to ensure it meets all regulatory and safety standards?
• Were there any unexpected successes or challenges—such as finding a specific anatomical landmark in the CT data or an intra-operative adjustment—and what did these teach you about patient-centred care?
• How does this experience of observing the clinical end-point of your laboratory work relate to the responsibilities of post-programme professional practice?

What will you take from the experience moving forward?

• What specific areas for continued development have you identified, such as a need for further training in advanced CAD software or a deeper understanding of sterile theatre protocols?
• How can you apply the insights gained from observing the surgical team to improve the customisation and functional design of future implants?
• What immediate next steps will you take—such as reviewing surgical feedback or updating laboratory documentation—to support the assimilation of this learning into your routine practice?
