1/12. actinobacillus actinomycetemcomitans-associated peri-implantitis in an edentulous patient. A case report.BACKGROUND: peri-implantitis is a risk factor for implant loss. Late bacterial infection of the peri-implant tissues and loss of alveolar bone in edentulous patients is caused by commensal oral anaerobic bacteria. In partially edentulous patients, porphyromonas gingivalis and occasionally actinobacillus actinomycetemcomitans are associated with peri-implantitis lesions. AIMS: To investigate the microbiology of a peri-implantitis case in an edentulous patient. methods: Anaerobic culture techniques and selective culture techniques for A. actinomycetemcomitans were used to study the peri-implant microflora at sites with and without bone loss. RESULTS: An anaerobic peri-implant microflora with several putative periodontal pathogens was found at sites with bone loss. Furthermore, a metronidazole-resistant A. actinomycetemcomitans was isolated. The A. actinomycetemcomitans infection did not respond to systemic doxycycline therapy, despite good susceptibility in vitro. CONCLUSIONS: The present case of severe A. actinomycetemcomitans-associated peri-implantitis shows the importance of pre-operative infection control. The findings in this case show that remaining teeth affected by periodontitis can be a serious risk factor for peri-implantitis.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
2/12. Advanced alveolar crest atrophy: an alternative treatment technique for maxilla and mandible.A concept of oral implantology for the treatment of advanced crest atrophy is presented: The lateral insertion technique with disk-design implants is less invasive than bone grafting. An implant case demonstrates the simultaneous surgery of an edentulous maxilla and a mandible. Implant loading zones in the anterior and posterior areas of the arch are created with disk-design implants. Their support is tricortical or multicortical. Seven to eight days after surgery, the implants are immediately loaded with fixed esthetic temporaries. After another 40 days, the definitive restorations on the implants can be fabricated. The procedure is safe and shortens chairtime.- - - - - - - - - - ranking = 4keywords = alveolar (Clic here for more details about this article) |
3/12. A clinical report about an unusual occurrence of post-anesthetic tongue swelling.dentures are routinely removed from the oral cavity before general anesthetic procedures. They are only reinserted much later when the patient returns to the room. This clinical report describes an edentulous patient who developed acute tongue swelling from venous congestion as a result of tongue recovery from general anesthesia. Her complete dentures were used to separate the residual ridges during the recovery period and relieved the congestion. Denture insertion increased the height and volume of the oral cavity, which reduced pressure on the tongue, preventing a cycle of tongue compression, congestion, and swelling. This unusual complication suggests that it may be prudent for the edentulous patient to be accompanied by their dentures in the perioperative period.- - - - - - - - - - ranking = 23.250536359651keywords = ridge (Clic here for more details about this article) |
4/12. Reconstruction of the severely resorbed atrophic edentulous ridge of the maxilla and mandible for implant rehabilitation: report of a case.We describe a case with a severely resorbed atrophic edentulous ridge in both the maxilla and mandible. The maxilla was reconstructed using a sinus-lifting procedure and onlay bone graft. The mandible was reconstructed by anterior osteotomy with an interpositional sandwich iliac bone graft at the symphysis area, subperiosteally with iliac bone chips mixed with hydroxylapatite bilaterally at the posterior atrophic ridge, and vestibuloplasty with a split thickness skin graft (STSG). After full-mouth implant rehabilitation, a 5-year follow-up of this case shows a satisfactory result.- - - - - - - - - - ranking = 139.50321815791keywords = ridge (Clic here for more details about this article) |
5/12. Prosthetic management of a total glossectomy defect after free flap reconstruction in an edentulous patient: a clinical report.Total glossectomy with surgical reconstruction can result in a significantly altered mandibular arch anatomy. In edentulous patients, lingual vestibules along with the mandibular alveolar ridge can be obliterated. With the absence of lower anterior dentition, support of the lower lip is lost and traction from surgical closure can cause the lower lip to collapse into the oral cavity. This report describes the prosthetic treatment of an edentulous total glossectomy patient with an unconventional custom impression procedure to develop and record proper lower lip and cheek support. It also discusses some issues involved in the prosthetic management of the total glossectomy patient.- - - - - - - - - - ranking = 24.250536359651keywords = ridge, alveolar (Clic here for more details about this article) |
6/12. Complicated comprehensive reconstruction: report of a case.This patient presented an interesting problem surgically from the standpoint of placement of implants immediately following removal of periodontally involved teeth at which time it was necessary to completely debride the alveoli. A 20-year history of smoking mitigated the prognosis in this particular case. Prophylactic antibiotics were used perioperatively, and his healing was uneventful. The prosthetic rehabilitation also details a specific technique to reproduce superior anterior esthetics to retain virtually the same appearance in the final implant retained fixed bridge. The case also demonstrates the efficacy of immediate implant placement and augmentation of the maxilla for adequate prosthetic management.- - - - - - - - - - ranking = 23.250536359651keywords = ridge (Clic here for more details about this article) |
7/12. Conservative management of patients with gross morphological changes following complete loss of teeth: case reports.This paper reports on the conservative management of five Nigerian edentulous patients who presented with shallow palatal vault, grossly resorbed and uneven alveolar ridges, flabby ridge forms, shallow sulci and loss of vertical face height as a result of tooth loss. There was associated loss of stability, retention and support of their complete dentures.Though the literature is replete with various problems in such patients, conservative treatment was employed in all the five cases, to achieve acceptable outcome.The paper recommends this treatment option and highlights the prosthetic techniques utilised in managing the patients including the factors that contributed to successful conservative treatment. In addition, the problems encountered when embarking on such treatments are enumerated and appropriate solutions proferred.- - - - - - - - - - ranking = 47.501072719302keywords = ridge, alveolar (Clic here for more details about this article) |
8/12. A technique for simultaneous fracture repair and augmentation of the atrophic edentulous mandible.A technique that uses autogenous rib grafts for repair of fractures of an atrophic, edentulous mandible and augmentation of the ridge has been presented. Nine cases have been treated in this manner. We advocate this treatment to promote healing of the fractures and to provide necessary mandibular bone for future vestibuloplasty and, ultimately, restoration of function with denture construction.- - - - - - - - - - ranking = 23.250536359651keywords = ridge (Clic here for more details about this article) |
9/12. Posterior maxillary osteotomies: an aid for a difficult prosthodontic problem.patients who have supereruption of posterior dentoalveolar segments provide an interesting challenge to the dentisr. The severe problems require a team approach to achieve the best results. Factors influencing the treatment include the periodontal status of the involved teeth as well as the concern of the patient. The posterior maxillary osteotomy provides the chance to maintain the vital functional teeth in an otherwise difficult situation. It must be emphasized that the patient must wear an opposing splint or prosthesis following surgery to prevent relapse. This conservative approach maintains the teeth and their vitality and anatomically repositions the supererupted segment to an improved functional position.- - - - - - - - - - ranking = 1keywords = alveolar (Clic here for more details about this article) |
10/12. Psychological reactions to edentulousness and treatment with jawbone-anchored bridges.Total edentulousness can lead to chewing problems as well as to feelings of insecurity and inferiority and considerable psycho-social problems. For many people a conventional removable denture is unsatisfactory. A new method - osseointegration - involves a titanium screw being operated into the jawbone and the attachment of a fixed bridge. In a controlled study, 26 patients were examined pre- and postoperatively 3 months and then 2 years after the insertion of a jawbone-anchored bridge. The majority of them state that there has been a significant improvement in their lives, that they have regained confidence in themselves, and that, in contrast to a conventional denture, they accept the fixed bridge as part of their body. More attention should be focused on psychological reactions to total edentulousness. Individuals who cannot be rehabilitated by means of conventional prosthetic procedures should be given the opportunity of having a jawbone-anchored bridge inserted. Such treatment means an odontological and psycho-social restitutio ad integrum.- - - - - - - - - - ranking = 186.00429087721keywords = ridge (Clic here for more details about this article) |
