A Three‐Dimensional Finite Element Analysis for Overdenture Attachments Supported by Teeth and/or Mini Dental Implants

Abstract

Three freestanding mini dental implants with flexible acrylic attachment systems supporting an overdenture were better choices than four mini dental implants with O-ring attachment systems, which showed the maximum flexing and stress values in this qualitative comparison.

Marginal Bone Level Changes and Oral Health Impact Profile (14) Score of Smokers Treated by Mandibular Mini Implant Overdentures: A 5-Year Follow-up Study

“…Therefore, vertical bone in the present study was close from expected bone loss at first year and even in the years after. 3,11,15,26,28 However, more bone loss was expected after the first year especially in this smokers' cohort and at 5 years of overdenture service. The present results could be claimed to the frequent maintenance and follow-up which was essential to keep bone loss within the acceptable limit.…”

“…These findings coincide with several studies. 12,[28][29][30] For example, Fatalla et al, 28 confirmed the influence of mini implant number and location on the amount of stress expected. They found higher stress values on the posterior implants than anterior implants in the parasymphyseal area.…”

Peri-implant stress distribution assessment of various attachment systems for implant supported overdenture prosthesis by finite element analysis – A systematic review

“…Remaining two studies employed attachments of different elastic modulus; no difference was present in between attachment types. 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 Excluded studies have been mentioned in ( Table 1 ). Total ten studies from five different countries were included in this systematic review.…”

“…Prakash V et al (2009) 41 Used only different number of bar attachment systems 9. Fatalla et al (2012) 42 Used teeth as an abutment in one model 10. Barao et al (2013) 43 Compared between implant supported fixed prosthesis and implant retained overdentures.…”

“…В них рас-сматриваются проблемы моделирования отдельно стоящего имплантата в челюсти (без протеза) [10][11][12], либо описана установка имплантатов на беззубой челюсти с использованием упрощенной геометрии протеза [13,14]. Вместе с тем на этапе планирования ле-чения и контроля остеоинтеграции имплантатов стоматологи все ча-ще используют компьютерную томографию, которая позволяет со-здавать более сложную геометрию конструкции и рассматривать весь этап планирования лечения, начиная с установки временных проте-зов на временных имплантатах и заканчивая фиксацией постоянных ортопедических конструкций.…”
