Aim of the Work: This study aimed to evaluate the stress distribution in and around one-piece narrow diameter implants, placed in tilted position, with different degrees of angles retaining mandibular overdenture. Materials and methods: Five finite element models (ABAQUS 13), were created to simulate five proposed groups for this study. Each model composed of the anterior region of edentulous mandible, in which 2 implants were virtually placed on the canine area retaining mandibular overdenture. Vertical, horizontal and oblique loads (35 N), were applied respectively, bilaterally on the both dental implants at the same time, through the overdenture. The maximum stress values (MSV) transmitted to the dental implants and peri-implant bone were analyzed by using finite element analysis (FEA) and compared with the yield strength values of the dental implant, cortical bone and cancellous bone. Results and conclusions: 1.The recordings of MSV at the dental implants and the cortical bone with all of the different proposed groups and loading conditions, were below their yield strength values. While the MSVs at the cancellous bone, exceeded its yield strength value, specially with the vertical load condition applied on the dental implants placed in a tilted position. 2. The MSVs taken from the dental implants and its surrounding bone, that placed vertically were less than the MSVs in and around the dental implants placed in the tilted position. 3. For the dental implants and its surrounding bone, placed with an equal degree of a tilted position, the MSVs decreased when the angle of placement increased.

“…The use of angled abutments is one of the methods to correct implant angulation due to low cost and reduced chair time [21]. However, the customized abutments seem to provide better results than angled abutments for ideal crown contours and peri-implant soft tissue support [22].…”

The Importance of the Appropriate Meso-Structure for the Success and Retention of Overdentures – Case Series

Oral Biologyhousing. Several different methods have been suggested to correct misangulated implant placements during the prosthetic phases of treatment. The most common method is the use of angulated or custom abutments, which allows positional correction. (Allows the correction of 40º of divergence) However, limitation still exists to achieve the ideal parallelism.The use of overdentures with meso-structures (ODMS) is one option for solving this problem. The meso-structure is fabricated by precision milling of casted frameworks [5][6][7][8][9][10]. Paralleled Locator attachments can be casted, screwed or laser-welded on the mesostructure in a more favorable position. In 2012, Kim et al. reported that implant overdenture using a locator bar system fabricated with the drill and tapping technique provided stability, support, and retention to dentures for fully edentulous patients [11]. However, considering the wide range of different intraoral locations of milled bars, there is a lack of information regarding the evaluation of meso- Avens Publishing Group Inviting Innovations Avens Publishing Group Inviting InnovationsKeywords: Overdenture; Meso-structure; Implant angulation; Stability AbstractLack of retention and stability is one of the most challenging problems in wearing conventional dentures due to the atrophy of the alveolar ridge. In addition, pain or discomfort can be frequently present with a poor load-bearing capacity of the tissues. The treatment of choice, among several options for edentulous patients is the implant-supported overdenture prosthesis. Locators have been the most popular method used as an unsplinted anchorage system. Poorly angled or unfavorably positioned implants cause lack of parallelism, resulting in compromised esthetics, phonetics, and function. The use of overdentures with meso-structures and paralleled Locator attachments is one option for solving this problem. The purpose of this report was to present a case series, and document a step-by-step procedure to fabricate overdentures with meso-structures and to discuss the indications, contraindications, advantages and disadvantages of meso-structures.

Ýmplantolojide yapýlan biyomekanik çalýþmalar sonucunda, implant materyal ve dizaynlarýnda önemli geliþmeler saðlanmýþtýr. Dolayýsýyla, diþ hekimliðinde implant uygulamalarý ve endikasyon çeþitliliði artmýþtýr. Pek çok vakada hatalý implantasyon veya anatomik yapýlarýn sebep olduðu istenmeyen açýlanmalar nedeniyle implantlar istenilen doðrultuda yerleþtirilememektedir. Bu olumsuzluklarý gidermek amacýyla üretici firmalar tarafýndan açýlý baþlýk tasarýmlarý kullanýma sunulmuþtur. Açýlý baþlýk tasarýmlarý implantolojide bilimsel deðerlendirme gerekliliði olan biyomekanik deðiþkenlerden biridir.
