Five years of experience using palatal mini-implants for orthodontic anchorage

Area of Science:

• Orthodontics and Dental Implantology
• Biomaterials and Medical Devices

Background:

• Absolute anchorage is crucial for complex orthodontic treatments, particularly Class II malocclusions.
• Palatal mini-implants provide a stable and minimally invasive solution for achieving superior anchorage.
• The Straumann Orthosystem offers a comprehensive kit for palatal mini-implant placement and management.

Purpose of the Study:

• To review 5 years of clinical experience with Straumann Orthosystem palatal mini-implants.
• To describe the clinical procedures for palatal mini-implant placement and orthodontic treatment.
• To present statistical results regarding the efficacy and complications of palatal mini-implants.

Main Methods:

• Retrospective analysis of 14 adult patients (12 female, 2 male) requiring fixed orthodontic appliances for Class II malocclusion.
• Placement of 16 palatal mini-implants (9 x 6.0 mm, 7 x 4.0 mm) with a 2.5 mm transmucosal neck length.
• Orthodontic treatment initiated 13 weeks post-insertion to ensure osseointegration.

Main Results:

• Successful osseointegration was achieved in all but one implant, which was lost due to poor hygiene.
• No surgical complications, such as nasal cavity perforation, were reported.
• Two implants required replacement due to tongue forces, resolved with a resin splint.

Conclusions:

• Straumann Orthosystem palatal mini-implants are clinically easy to use and highly effective for orthodontic absolute anchorage.
• These mini-implants represent an efficient auxiliary device for managing challenging orthodontic cases.
• The system demonstrates a favorable safety profile and successful osseointegration in the reviewed patient sample.
