Ortodontik Mini İmplantlar
Özet
Klinik ortodonti uygulamalarında ankraj planlaması, tedavi başarısı için kritik bir öneme sahiptir. Geleneksel ekstra oral apareylerin hasta kooperasyonu zorluğu ve rahatsızlık yaratması gibi dezavantajları, son yıllarda dental implantlar, onplantlar, mini plaklar ve özellikle adaptasyon kolaylığı, düşük maliyet gibi avantajları olan mini implantlar gibi geçici ankraj aygıtlarının (TAD) kullanımını yaygınlaştırmıştır. Mini implantlar, baş, boyun ve gövde olmak üzere üç bölümden oluşur; hooklu, top başlı, delikli, tek slotlu ve braket başlı gibi farklı tasarımlarla direkt ya da indirekt ankraj sağlayarak diş hareketlerini kolaylaştırırlar. Uygulama şekline göre self-tapping ve self-drilling olarak ikiye ayrılan bu aygıtlarda primer stabilite; kemik kalitesi, kortikal kemik kalınlığının en az 1 mm olması ve implant tasarımı gibi faktörlere bağlıdır. Mini implantların başarısı mekanik ankraj desteği sağlamasıyla ölçülürken; implant, hekim ve hasta kaynaklı faktörler ile kök yakınlığı başarısızlığa neden olabilir. Mobilite, yumuşak doku irritasyonu, enfeksiyon ve ağrı gibi komplikasyonların önlenmesi için ortodontistlerin anatomiye hâkim olması, doğru bölgeye doğru teknik ve açıyla yerleşim yapması ve süreci yakından takip etmesi gerekmektedir.
Anchorage planning holds critical importance for treatment success in clinical orthodontics. The disadvantages of traditional extraoral appliances, such as patient compliance difficulties and discomfort, have driven the widespread use of temporary anchorage devices (TADs) in recent years, including dental implants, onplants, miniplates, and particularly mini-implants, which offer benefits like ease of adaptation and low cost. Mini-implants consist of three components—head, neck, and body—and facilitate tooth movements by providing direct or indirect anchorage through various designs such as hooked, ball-head, bracket-head, single-slot, and button-type variations. Classified as self-tapping or self-drilling based on the insertion method, their primary stability depends on bone quality, a cortical bone thickness of at least 1 mm, and implant design. While the success of mini-implants is measured by maintaining stable anchorage support, implant-, clinician-, and patient-related factors, along with root proximity, can lead to failure. To prevent complications such as mobility, soft tissue irritation, infection, and pain, orthodontists must have a thorough understanding of anatomy, place the device in the correct area with the proper technique and angle, and monitor the process closely.
