Nasal defects can occur as a result of head and neck trauma, or due to partial or complete ablation or resection of the tumor in the nasal area and surroundings. Smaller defects can be reconstructed ...surgically while large defects are mainly reconstructed combined surgically and prosthetically. The aim of this paper was to present prosthetic reconstruction of the nasal defect by colored vinyl polysiloxane prosthesis retained with craniofacial basal disc implants. An adequate aesthetics and stability of the prosthesis was achieved during mandible and mimic muscles movements.
Hypodontia of upper lateral incisors is significant aesthetic problem in young people. Ideal solution to this problem would be an implant placement, but there is a problem of unfinished growth and ...development. It is therefore necessary to have a temporary solution in order to maintain normal stomatognathic system functions and solve aesthetic problems until the final restoration is placed. The aim of this study was to show the possibility of treating hypodontia of permanent upper lateral incisors by creating adhesive bridge in one visit. A 15-year-old patient was referred to the Department for Prosthodontics, School of Dental Medicine in Belgrade with hypodontia of permanent upper lateral incisors. The patient had braces until 14 years of age after which she was rehabilitated with partial denture that was neither aesthetically nor functionally acceptable solution for her and significantly affected her emotional security. The adhesive bridge was made using GC composite fibers and a set of GC composite materials for the purpose of temporary replacement of missing teeth. This treatment provided good functional and aesthetic results. The space for the placement of two endosseous implants is preserved and a period of adaptation positively influenced the patient's social development in sensitive adolescent age.
Orbital defects after tumor resection (exenteration of orbital content) have been traditionally reconstructed with adhesive-retained craniofacial prostheses, also known as epistheses. The ...breakthrough in rehabilitation of facial defects with implant-retained prostheses has come with development of modern silicones (vynilpolysiloxane) and bone anchorage called osseointegration. Craniofacial implant technology offers improved reconstructive options to patients. This paper describes therapeutical procedure on a patient who received craniofacial implant-retained orbital prosthesis after orbital exenteration. The patient reported excellent prosthesis handling and stability.
The classification of dental metallic biomaterials is illustrated in depth, with a focus on dental casting alloys. Methods for creating dental prostheses as well as manufacturing shape memory alloys ...(SMA) Ni-Ti alloys are briefly given. The effect of surface oxide films on metallic biomaterials in the human environment is considered. In order for metal implants to interact with the human body, they need to meet certain requirements.
