Edentulous patients have reported difficulties in managing complete dentures; they have also reported functional concerns and higher expectations regarding complete dentures than the dentists who have treated them. Some of the objectives of definitive fixed implant prosthodontic care include predictable, long-term prostheses, improved function, and maintenance of alveolar bone. One of the keys ...

BACKGROUND Occlusal overloading causes peri-implant bone resorption. Previous studies examined stress distribution in alveolar bone around commercial implants using three-dimensional (3D) finite element analysis. However, the commercial implants contained some different designs. The purpose of this study is to reveal the effect of the target design on peri-implant bone stress and abutment micro...

a 48 year old patient was candidate for anterior mandibular reconstruction by 2 fixtures of branemark implant. residual infection lead to removal of one of the implants from the extracted tooth socket. afterwards, 2 fixtures of bonefit was inserted adjacent to previously placed branemark implants and final prosthesis were loaded in a joint cemented and screwed design.

background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...

Preservation of the breast skin envelope during immediate implant-based breast reconstruction is important for producing symmetrical and natural-looking breasts. We propose the lazy S design for the closure of round-shaped wounds with the hope of improving the aesthetic outcomes and reducing the tension on the wound by preserving the skin. Additionally, the direction of tension is dispersed due...

In this paper, we report the benefit of Computer Tomography (CT), reverse engineering (RE) and rapid prototyping (RP) in individual implant production for maxillofacial surgery. The design and fabrication processes includes: a) processing medical image data of a patient’s pathologically defective area having a symmetrical part to construct a three-dimensional (3D) digital model; b) forming an i...

STATEMENT OF PROBLEM The transition from implant to abutment is solid in 1-piece (1P) and broken in 2-piece (2P) implant designs. This difference may affect occlusal load distribution and marginal bone response. PURPOSE To determine whether 1P and 2P implants with equivalent geometries exhibited stresses and strains differently under applied loading conditions. MATERIALS AND METHODS Design ...

Purpose. To evaluate implant survival, peri-implant bone loss, and complications affecting fixed full-arch (FFA) restorations supported by implants with a knife-edge thread design and nanostructured, calcium-incorporated surface. Methods. Between January 2013 and December 2015, all patients referred for implant-supported FFA restorations were considered for enrollment in this study. All patient...
