- PURPOSE: The purpose of this retrospective study was to assess the incidence of the neurosensory disturbance (NSD) after sagittal split osteotomy and evaluate NSD in relation to patient age, gender, satisfaction, and effect of steroids. PATIENTS AND METHODS: Questionnaires were mailed to all patients (31 women, 19 men) who underwent bilateral sagittal split osteotomy between 1995 and 1999, at least 1 year after the operation. Patients were queried about perceived NSD in the distribution of both inferior alveolar and lingual nerves, duration of these changes, and any influence of these changes on their quality of life. RESULTS: Eightysix percent of the mailed questionnaires were returned and analyzed (27 women, 16 men). Eight patients with 10 affected sides (11.6% of sides) reported long lasting NSD correspond-ing to the distribution of the inferior alveolar nerve. NSD was re-ported in 16.7% of the operated sides in women, while 3% of the operated sides in the men had such changes. Fifty percent of the operated sides in patients over 40 years of age were affected. Steroid treatment seemed to decrease NSD. Four patients (9%) were not satisfied, but only 1 attributed the dissatisfaction to sensory impairment. CONCLUSION: The incidence of NSD after sagittal split osteotomy in-creases in patients over the age of 40. Steroid regimen might be beneficial in reducing NSD after sagittal split osteotomy, although further investigation is required. The discomfort of the nerve damage seems outweighed by the result of function and esthetics.

- PURPOSE: The purposes of this study were 1) to evaluate the survival rate of implants placed in maxillary sinuses augmented with bovine hydroxyapatite and autogenous bone 6 months before implant surgery and 2) to estimate dimensional changes of the bone graft with time using a new radiographic method. PATIENTS AND METHODS: Thirty maxillary sinuses in 20 consecutive patients with severe resorption (mean, 3.8 mm of remaining alveolar bone) were augmented with a mixture of 80% bovine hydroxyapatite and 20% autogenous bone mixed with fibrin glue to enable the placement of screw-shaped dental implants. After 6 months of primary healing, 108 implants were placed and followed with clinical and radiographic examinations during the first year of loading. Measurements of changes in height, width, and length of the grafted material were made on tomographic Scanora (Soredex Orion Corporation Ltd, Helsinki, Finland) and panoramic radiographs taken 3 and 12 months after grafting and after 1 year of bridge loading. RESULTS: Ten implants in 6 patients were lost during the study (9 before loading and 1 after 1 year of functional loading), for a survival rate of 90.7%. All patients received fixed restorations, and the bridge survival rate was 100% after 1 year of loading. Small (<10%) but statistically significant dimensional changes in the grafted material were seen during the study period. CONCLUSIONS: Acceptable short-term results can be obtained with implants placed after the use of bovine hydroxyapatite and autogenous bone for maxillary sinus floor augmentation. These grafts show good resistance to resorption.

- PURPOSE: To evaluate treatment outcome with Zygoma fixtures (Nobel Biocare, Göteborg, Sweden) with regard to fixture survival, patient satisfaction, and function of prosthesis replacement. MATERIALS AND METHODS: The treatment outcome of 76 patients treated with 145 Zygoma fixtures at 16 centers was evaluated. Patient's and dentist's evaluations of the functional and aesthetic outcome of the treatment were assessed at delivery of prosthesis and at the 1-year follow-up visit. At the 1-year follow-up visit, the status of the peri-implant mucosa around the abutments and the amount of plaque were registered. RESULTS: Sixty-six of the 76 patients, with 124 Zygoma fixtures supporting the prosthetic restorations, were evaluated at the 1-year follow-up. The overall survival rate for the Zygoma fixtures was 97.9% after 1-year of follow-up. Eighty percent of the patients were fully satisfied with both aesthetic and functional outcome at the time of prosthetic insertion and at the 1-year follow-up. All reported data from the dentists, with the exception of one restoration with several abutment screw loosenings, scored from acceptable to excellent for the aesthetic and functional outcome of the treatment. The status of peri-implant mucosa was recorded as normal in approximately 60% of the sites. Plaque, when present, was more often detected on the palatal surfaces compared with the buccal surfaces. CONCLUSION: This 1-year follow-up of Zygoma fixtures has shown good results with an acceptable number of minor complications and a majority of satisfied patients.
