Computerized tomography with CT models for contemporary ramus frame implant planning and construction

Area of Science:

• Dental Implantology
• Oral and Maxillofacial Surgery
• Biomaterials Science

Background:

• Tooth loss leads to progressive mandibular bone resorption, compromising denture stability and aesthetics.
• Conventional dentures in atrophic mandibles exhibit poor retention and function.
• Standard endosteal implants may require bone grafting in severely resorbed mandibles.

Purpose of the Study:

• To evaluate the efficacy of the third-generation ramus frame implant (RFI) in managing advanced mandibular atrophy.
• To highlight the advantages of RFI over conventional prostheses and traditional implants in severe bone loss scenarios.

Main Methods:

• Utilizing computed tomography (CT) and computer-aided design/stereolithography (CAD/SLA) for precise RFI planning and fabrication.
• Employing homologous grafting materials and platelet-rich plasma (PRP) to enhance bone regeneration with RFI.
• Describing the immediate, implant-supported nature of the RFI prosthesis.

Main Results:

• The third-generation RFI integrates advanced digital technologies for improved planning and placement.
• RFI facilitates enhanced bone regeneration through the use of grafting materials and PRP.
• Predictable component manufacturing and prosthesis retrievability are key benefits.

Conclusions:

• The ramus frame implant (RFI) is a viable and advanced treatment option for patients with severe mandibular atrophy.
• Third-generation RFI, enhanced by CT and CAD/SLA, offers predictable, stable, and retrievable solutions for complete denture instability.
• This implant system improves patient outcomes by addressing anatomical and functional challenges in atrophic mandibles.
