One-piece implants: Careful approach for complex rehabilitation

Area of Science:

• Dental Implantology
• Biomaterials Science

Background:

• Conventional two-piece dental implants involve a connection between the implant and abutment, which can be a source of complications.
• Microgaps at the implant-abutment connection can harbor bacteria, potentially leading to peri-implant bone loss.
• Mechanical failures like screw loosening and abutment fractures are common issues with two-piece implant systems.

Observation:

• One-piece implant designs eliminate the implant-abutment connection, thereby removing the microgap.
• These implants exhibit high cortical stabilization, enabling immediate placement and functional loading.
• Historically, one-piece implants were used as temporary solutions but became difficult to remove due to osseointegration.

Findings:

• The absence of a microgap in one-piece implants significantly minimizes peri-implant bone loss.
• One-piece implants demonstrate a reduced incidence of mechanical complications, such as screw loosening and abutment fractures.
• Immediate function protocols with one-piece implants offer advantages over traditional two-stage surgeries, including fewer appointments, shorter treatment duration, and less trauma.

Implications:

• One-piece implants are a viable alternative for restoring edentulous arches, particularly in cases of significant bone resorption.
• Careful treatment planning is crucial to mitigate comorbidities associated with augmentation procedures and achieve satisfactory esthetic results.
• The use of one-piece implants, when indicated and properly planned, can lead to predictable clinical outcomes and improved patient satisfaction.
