Additively manufactured sub-periosteal jaw implants

Area of Science:

• Dental Implantology
• Biomaterials Engineering
• Additive Manufacturing

Background:

• Severe jaw bone atrophy presents a significant challenge for conventional endosseous dental implant success.
• Existing treatments often involve complex and lengthy bone grafting procedures.

Purpose of the Study:

• To introduce and describe the innovative concept of additively manufactured sub-periosteal jaw implants (AMSJIs).
• To present AMSJIs as a viable alternative for full maxillary rehabilitation in patients with extreme bone atrophy.

Main Methods:

• Utilizing digital datasets of patient jaws and wax trials for precise segmentation and design.
• Designing a custom sub-periosteal frame, abutments, and suprastructure using 3D modeling.
• Employing three-dimensional (3D) printing with titanium alloy for implants and suprastructure, and polymer for the provisional denture.

Main Results:

• AMSJIs provide a customized, prosthesis-driven solution for severe jaw bone atrophy.
• The technique facilitates immediate functional restoration in a single surgical session.
• This approach avoids the need for bone grafting procedures.

Conclusions:

• Additively manufactured sub-periosteal jaw implants (AMSJIs) represent a significant advancement in treating severe jaw bone atrophy.
• This technique offers a predictable and efficient alternative to traditional methods, applicable to various defect types.
• AMSJIs enable immediate functional and aesthetic rehabilitation, improving patient outcomes.
