Effect of Different Bar Designs on Axial and Nonaxial Retention Forces of Implant-Retained Maxillary Overdentures: An In Vitro Study

Rehabilitation of an Extremely Edentulous Atrophic Maxilla with a Pseudoskeletal Class III Relationship

“…For patients with extensive residual ridge resorption, the replacement of hard and soft tissues with a removable denture may be a more suitable option than the use of a cemented (or fixed type) restoration [1–4]. The analysis and management of the restorative space in edentulous patients with implant overdentures are important for the planning of implant placement and for the design of the denture [16, 19, 20].…”

“…Denture teeth (SR; Ivoclar Vivadent, Ellwangen, Germany) were set and tried in before the finishing process. The denture was finished with the use of an autopolymerizing acrylic resin base material (PalaXpress Ultra; Heraeus Kulzer; Germany) and delivered back to the office on the same day (Figures 10–12) [1–4, 17, 18].…”

“…The prosthetic rehabilitation of a fully edentulous and atrophic arch with implant-retained dentures requires thorough planning and should not only provide the correct vertical height and maxillary-mandibular relationship but also be esthetically acceptable [1–4]. The use of implant-supported overdentures is a treatment option for the restoration of fully edentulous jaws when conventional dentures have deficient retention due to advanced bone atrophy [1–4]. In older complete denture wearers, advanced jawbone atrophy simulates the clinical situation of a skeletal class III relationship combined with vertical alveolar bone loss; this condition is classified as pseudoskeletal class III.…”

Implant‐supported bar overdentures in patients treated surgically for head and neck cancer: Two case reports

“…These 2 types of bars have poor retention in case of lateral forces. 5 Dos Santos MBF. et al demonstrated that a round section bar exerts less tension on the « clips» and prosthetic screws than the Hader bar.…”

İmplant Destekli̇ Overdenture Protezlerde Kullanilan Hassas Tutucular

“…Isırma kuvvetleri benzer bulunmuĢ, ancak ataçmanlı bar ile oluĢturulan protezde oblik kuvvetler daha fazla görül-müĢ ve daha fazla komplikasyon bildirilmiĢtir. Elsyad ve arkadaĢları 17 , farklı bar dizaynlarının retansiyonunu in vitro olarak kıyasladıkları çalıĢmada Hader bar sisteminin, Dolder bar ve millenmiĢ bar sitemine kıyasla maksiller implant destekli overdenture uygulamalarında aksiyal kuvvetlere karĢı daha iyi retansiyon gösterdiğini bildirmiĢlerdir. Toio ve arkadaĢları 18 , millenmiĢ bar uyguladıkları protez hastalarının 2 yıl takibi sonucunda vida gevĢemesi, vida kırılması, bar kırılması, protez kaidesinin kırılması ve protez kaidesinden diĢin ayrılması gibi komplikasyonlar bildirmiĢlerdir.…”
