A screw lock for single-tooth implant superstructures.

BACKGROUND: The most common complication in a single-tooth implant restoration is abutment screw loosening. Instability of the prosthetic superstructure is expressed by difficulty in chewing and functioning, as well as soft-tissue soreness and/or swelling that could lead to screw fracture. Manufacturers of oral implants have attempted to refine the connecting parts of the prosthesis to achieve a more predictable tightening method for the screws. METHODS: To maintain the abutment screw tightly in its correct position, the authors developed a technique in which an elongated hexagonal titanium bar is inserted into the hexed fixed screw head. The screw is locked, and the bar is then fixed with a light-cured composite resin material that serves to seal the retaining screw access hole. The occlusal hexagonal bar thus serves as a secure screw lock that can be easily removed if needed. RESULTS: The authors have used the hexagonal bar for almost three years on 120 single-tooth screw-retained prostheses in 100 patients (65 in the first and second premolar region, 40 in the incisor region and 15 in the posterior molar region). All of these prostheses functioned successfully, including those with wider occlusal planes and increasing occlusal forces. No screw loosening or fractures were noted in any of the fixtures. CLINICAL IMPLICATIONS: This technique secures and stabilizes the single-tooth prosthesis, reduces chair time on follow-up procedures and reduces unnecessary frustration in patients and dental team members.

Periarticular Fractures After Total Knee Arthroplasty: Principles of Management.

Periarticular fractures about total knee replacements are sustained by 0.3% to 2% of patients who have undergone knee arthroplasty. The patient with such a fracture is usually a woman in her seventh decade who has osteoporosis and may also have rheumatoid arthritis that is being treated with corticosteroids. The treatment of such fractures is aimed at restoring the patient's functional status to the pre-fracture level. Accomplishing this requires healing of the fracture and retention of a mobile and painless prosthesis in correct alignment. These goals are often difficult to achieve because there is little experience with these uncommon fractures, the healing environment is suboptimal, and knee arthroplasties have a low tolerance for any resulting alteration in alignment. In general, nondisplaced fractures are treated nonoperatively, and displaced fractures require open reduction, rigid internal fixation, and bone grafting. If the prosthesis is loose, or if rigid fixation cannot be obtained, component revision is the treatment of choice.

Prosthetic restoration following maxillary resection without an oroantral defect: a case report.

PURPOSE: The aim of this article was to present the oral rehabilitation of a patient with a large, created intraoral defect after the surgical extirpation of a pathologic process. MATERIALS AND METHODS: On osseointegrated oral implants, a bar was fabricated to support a partial overdenture by means of attachments. RESULTS: The treatment was successful and the construction has been in service for more than 5 years. CONCLUSION: In cases with large intraoral defects removable dentures may have clinical advantages over fixed partial dentures. In this patient the restoration of missing teeth, alveolar crest, and soft tissue was accomplished at the same time oral function was restored, and good oral hygiene access was obtained.

Femoral shaft fracture after hip arthroplasty: a system for classification and treatment.

Twenty-one consecutive cases of femoral shaft fracture after hip arthroplasty treated at the University of Illinois affiliated hospitals were reviewed. Adequate follow-up and radiographs were available for 19 patients. The length of follow-up after fracture ranged from 2 to 13 years, with a mean of 3.1 years. The time from index procedure to fracture averaged 2.6 years, with a range of 10 days to 11 years. The primary femoral stem was cemented in 11 hips and cementless in 8 hips. Six patients were treated nonoperatively and 13 operatively. Three had fracture fixation with retention of a well-fixed prosthesis and 10 had prosthetic revision. Cortical allograft was used in 5 cases. Sixteen of the 19 patients returned to their prefracture level of function and ambulation. The factors important to treatment are fracture stability, implant stability, and adequacy of bone stock. A classification system based on these factors and recommendations for treatment are proposed.

[First results of our experience with the Fabian's prosthesis].

Report on our experience with Fabian's prothesis as alternative therapy to benign prostate hyperplasia (B.P.H.) surgery. Throughout 1990 ten patients with various surgical contraindications were implanted the above device. In spite of the series small size (10 patients) and short follow-up (4 to 11 months), we believe the 70% good results obtained is very encouraging and can either be of help to banish the ominous indwelling vesical catheter, a permanent evidence of Urologists' failure in the prostate obstructive disease, or it will allow us to relief patients with B.P.H. non-secondary to other more aggressive therapies.

Problems reported by patients before and after prosthodontic treatment.

PURPOSE: This study sought to investigate problems reported by patients before and after prosthodontic treatment. MATERIALS AND METHODS: Patient-reported problems were studied using the item list contained in the German version of the Oral Health Impact Profile in a convenience sample of 107 prosthodontic patients before (T0), 1 month after (T1), and 6 to 12 months after treatment (T2). "Frequently reported" problems were defined as impacts experienced fairly often or very often. The prevalence of frequently reported problems was compared among treatment groups and across appointments. RESULTS: At baseline, the most prevalent frequently reported problems were "difficulty chewing" (31%), "take longer to complete a meal" (28%), "food catching" (26%), "uncomfortable to eat" (24%), and "unable to eat (because of dentures)" (23%). At T2, the most prevalent frequently reported problems were "sore spots" (5%), "painful gums" (4%), "discomfort (because of dentures)" (3%), and "sore jaw" (2%). The number of reported problems decreased from 18.0 (T0) to 7.5 (T1), and further to 4.5 (T2). The decrease was the fastest in fixed partial denture wearers and the slowest in removable partial denture wearers. Some problems emerged during or after prosthodontic treatment. The kind of pre- and posttreatment problems differed substantially. CONCLUSION: The number of problems decreased substantially after prosthodontic treatment. Fixed partial dentures more effectively influenced the problems reported before treatment than did removable partial or complete dentures.

Rehabilitation of failing dentition with immediate denture prostheses: technique for a predictable esthetic and functional outcome.

The goal of this article is to describe the clinical and laboratory procedures used in the fabrication of immediate complete and removable partial denture prostheses. In this type of treatment, achieving optimal esthetic and functional outcomes is complicated because of the absence of the try-in stage. To overcome this limitation, a technique that predictably transfers the information obtained during esthetic dentofacial analysis from the patient to the laboratory in the form of an incisal-occlusal plane guide is described. Stability, support, and retention of the immediate partial denture prosthesis can be improved with the incorporation of cast clasp assemblies, and its fabrication technique is presented in this article.

[Application of implants for dental prostheses in indications for complete dentures. 2].

An interesting clinical case of fixed dental prostheses is described, performed via Bulgarian bioceramic intraosseous implants and two retained teeth on the upper jaw, i.e. indications for complete prostheses in a 38-years old female patient. The case has been solved in a way so that when necessary (retention of implants) guarantees a removable prosthesis with Bulgarian traverse-joint elements.
