Stress distribution of four implant supported overdentures with tilted standard-sized implants and mini implants

Işıl Turp, Volkan Turp, İlkin Tuncel, Aslıhan Üşümez

Purpose: The goal of the current study is to evaluate the stress distribution when tilted implants and mini-implants are used to support a mandibular overdenture.

Materials and Methods: Three-dimensional (3D) finite element models of mandibular overdentures were established using four, axial, standard-sized implants (SA model), four standard-sized implants with the mesial ones axial and the distal ones tilted (ST model) and four mini-implants (MA model) with Locator attachments. On each model, a 100 N load was applied to the overdenture in four different directions; bilateral vertical, unilateral vertical and oblique load on the posterior region, and a vertical load on the incisors. The stresses distributed at the peri-implant bone, implants, the prosthetic components, and the overdentures were evaluated.

Results: Non-axial posterior loading caused higher stress values in the implant and the prosthetic component than axial posterior loading. Lower stress values of the implant and the prosthetic component were observed in the ST model than SA model. The stress distribution in the overdenture at posterior loads were mostly observed around the implants.

Conclusion: Less prosthetic complications may be expected when the treatment option in the ST model is used. Fatigue fractures may occur around the implants in the overdentures, precautions are advised.

Açılı standard implant ve mini implant destekli tam protezlerde gerilimin değerlendirilmesi

Işıl Turp, Volkan Turp, İlkin Tuncel, Aslıhan Üşümez

Amaç: Bu çalışmanın amacı mandibular implant üstü tam protezleri desteklemek için açılı implantlar ve mini implantlar kullanıldığındandaki gerilim dağılımını değerlendirmektir.

Gereç ve Yöntem: Dört adet, düz, standart büyüklükte implanta sahip (SA model); dört adet, mezialdekiler düz ve distaldekiler açılı, standart büyüklükte implanta sahip (ST model) ve dört adet, düz mini implanta sahip (MA model) Locator tutuculu implant üstü mandibular tam protezlerin üç boyutlu (3D) sonlu eleman modelleri oluşturuldu. Her modelde implant üstü tam proteze bilateral dik, unilateral dik, unilateral oblik ve kesicilerden dik olacak şekilde dört farklı yönde 100 N kuvvet uygulandı. Peri-implant kemikte, implantta, protetik komponentlerde ve protezde dağılan gerilimler değerlendirilmiştir.

Bulgular: Dik olmayan posterior yükleme, dik yüklemeye göre implantta ve protetik komponenette daha yüksek stress değerlerine sebep olmuştur. İmplant ve protetik komponentte ST modelde SA modele göre daha düşük gerilim değerleri gözlenmiştir. Posterior yüklemelerde implant üstü tam protezde gerilim dağılımı implantların etrafında daha yoğun gözlenmiştir. Sonuç: ST modeldeki tedavi seçeneğinin kullanıldığı durumlarda daha az protetik komplikasyon beklenebilir. İmplant üstü tam protezlerde implantların etrafında yorgunluğa bağlı kırılmalar meydana gelebilir

Keywords: Açılı implantlar, mini implantlar, sonlu elemanlar analizi, locator, implant üstü tam protez
