• Customized treatment plan: Based on the digital design, a detailed treatment plan is developed. This plan includes the specific procedures required, such as orthodontics, veneers, implants, or gum contouring, along with the sequence and timeline of treatment.
• Patient approval: The patient reviews the digital design and treatment plan, providing input and approval before any physical work begins. This collaborative approach ensures that the patient is fully involved in the decision-making process.

4. Execution of the treatment plan

• Guided procedures: The digital design serves as a guide for the execution of the treatment plan. For example, the precise placement of dental implants or orthodontic appliances can be planned and executed with the aid of 3D-printed surgical guides or aligners based on the digital model.
• Real-time adjustments: During treatment, the digital model can be referenced to make real-time adjustments as needed, ensuring that the final result aligns with the planned design.
• Final restorations: Once the dental procedures are complete, the final restorations, such as crowns, veneers, or bridges, are fabricated based on the digital design and placed to achieve the desired aesthetic outcome.

5. Follow-up and maintenance

• Post-treatment care: After the treatment is completed, the dentist provides instructions for maintaining the new smile, including oral hygiene practices and regular dental check-ups.
• Long-term monitoring: Regular follow-up appointments are scheduled to monitor the health and appearance of the teeth, gums, and restorations. Any necessary adjustments can be made to ensure the longevity of the results.
