Study design: In this study, ring orthosis design and manufacturing was performed by using rapid prototyping technology.

Introduction: Swan neck and boutonniere deformities may occur because of various reasons such as tendon injuries, sharp object injuries, or rheumatic diseases. Although the ring orthoses are the most commonly used conservative treatment method for swan neck and buttonhole deformities, they cannot be widely used because they are both difficult to produce and esthetically unsatisfied with the patients.

Purpose of the study: In this study, it was aimed to manufacture with an orthosis design that is fully compatible, more esthetic, faster, and easily produced.

Methods: 3D printing technologies are used in design and manufacturing. The 3D scanner is used in the measurement process, and the 3D printer is used in the manufacturing process.

Results: As a result of the study, a more esthetically pleasing and comfortable orthosis was made faster.

Discussion and conclusions: As a result of the study, the thickness of the material should not be less than 5 mm.
