Dramatic course of osteomyelitis in a patient treated with immediately placed dental implants suffering from uncontrolled diabetes: A case report.

Purpose: To report a rare and dramatic complication following immediate dental implant placement in a heavy smoker, who had a delayed diagnosis of uncontrolled diabetes.

Materials And Methods: In this case report we present the dramatic course of a 64-year old female patient treated with five immediate post-extractive dental implants in the mandible, who developed osteomyelitis, which manifested initially as local peri-implant inflammation and progressed into a spontaneous jaw fracture, despite repeated surgical interventions and antibiotic courses over a 3-year period, until diabetes was diagnosed.

Results: A symptom-free status could be achieved only after partial mandibulectomy, treatment of diabetes and reconstruction with a microvascular fibula free flap.

Long-term peri-implant bone level changes of non-vascularized fibula bone grafted edentulous patients.

Long-term results of reconstructions and prosthetic rehabilitation of patients presenting severely atrophied edentulous ridges remains a challenge for clinicians. Among the various available augmentation materials there is evidence that avascular fibula bone grafts possess a reliable resistance against resorption and may thus provide a valuable source to reduce the loss of vertical bone height after reconstruction of the severely atrophied mandible and maxilla. The purpose of the present study was to assess long-term crestal bone level stability in avascular fibula bone grafts.

2-Dimensional changes of the soft tissue profile of augmented and non-augmented human extraction sockets: a randomized pilot study.

Aim: This study identified the soft tissue changes of the alveolar ridge at different time points within 12 weeks after tooth extraction with and without socket augmentation.

Materials And Methods: In 38 patients with single tooth extractions, 40 sockets were augmented and 39 extraction sockets were not augmented. At 2, 4, 6, 8 and 12 weeks impressions were taken and casts digitized with a laser scanner.

Survival analysis of dental implants and implant-retained prostheses in oral cancer patients up to 20 years.

Objectives: The purpose of this study was to evaluate the long-term survival rate and potential influencing factors of dental implants and implant-retained prostheses in oral cancer patients who had undergone surgical tumor resection.

Material And Methods: In the present study, 157 patients (95 females and 62 males with a mean age of 53.7 years) with 830 implants were included.

Analysis of soft tissue display during enjoyment smile. Part II: elder Caucasians.

Esthetic parameters in elder patients are essential in esthetic oral rehabilitation. To date, no study has quantified the amount and frequency of soft tissue display in the papilla area in patients over 50 years of age. Photographic examination of 42 fully dentate patients with a mean age of 59 years was performed during enjoyment smile.

Bone physiology in human grafted and non-grafted extraction sockets--an immunohistochemical study.

Purpose: The aim of the present immunohistological investigation was to define and compare the osteogenic potential with the vascularization of the provisional matrix in grafted and ungrafted extraction sockets after 4 and 12 weeks of healing.

Methods: A total of 33 Patients (15 women, 18 men) with 65 extraction sites with a mean age of 54.4 years (30-73 years) participated in this study.
