- BACKGROUND: Apical peri-implantitis is often diagnosed by clinical findings such as pain, redness, tenderness, swelling, and sometimes the presence of a fistulous tract. There are few theories about how such a lesion occurs. Hence, the current clinical treatment protocols are scanty. PURPOSE: The aim of this report was to evaluate and confer a more extended surgical protocol and to discuss possible predisposing factors for the development of retrograde peri-implantitis. MATERIALS AND METHODS: Two patients were extensively evaluated with regard to clinical signs, implant treatment, postoperative complications, and surgical treatment. The surgical protocol comprised debridement, with the additional removal of the apical portion of the affected implant. Postoperative checkup included clinical examination and radiographs. The follow-up period ranged from 1 to 3 years following surgical debridement. The possible predisposing factors are also discussed in the article. RESULTS: Both cases healed uneventfully with no further symptoms. Radiographs revealed complete bone fill into the resected area and continuous stable bone levels around the previously affected implants. CONCLUSIONS: It is concluded that recommendations for treatment of apical peri-implantitis are still minimal. In the present study, a surgical approach with resection of the apical portion of the affected implants in combination with debridement is suggested. Our experience was that partially resected oral implants remain osseointegrated and also function well clinically with a follow-up period up to 3 years.

- Development of a new questionnaire, Oral Health-Related Quality of Life - Neurosensory Disturbances after Orthognathic Surgery (OHRQL-NDO), designed to measure the effects of neurosensory disturbance (NSD) on patients' oral health-related quality of life (OHRQL) and to evaluate reliability and validity of this questionnaire.A questionnaire including 11 items was constructed. Thirty patients with NSD affecting the lower lip and/or chin following orthognathic surgery were included. Convergent validity was assessed by comparing OHRQL-NDO with OHIP-14 and two global questions. Test-retest reliability was assessed by asking the patients to complete OHRQL-NDO at two different occasions with an interval of two to threeweeks.The internal consistency, measured with Cronbach's alpha, was 0.84. The test-retest reliability, measured with ICC, was 0.89 (95% CI 0.77-0.95). The correlation between the mean sum score for the OHRQL-NDO and the mean sum score for the OHIP-14 was r=0.75, using Pearson correlation coefficient. The correlations between the mean total score for the OHRQL-NDO and the global questions 1 and 2 were r=0.74 and r=0.72, respectively.The current instrument OHRQL-NDO is a promising test, but needs further development to better capture the different aspects of OHRQL. Further tests of the questionnaire must follow in other samples to finalize the instrument.

- Background: NEOSS® (Neoss Ltd., Harrogate, UK) dental implant system was introduced on the clinical arena in 2003. It is important that novel implant systems are systematically evaluated in a multicenter setting. Purpose: The aim of this study was to follow a large number of consecutively treated patients, with NEOSS dental implant system, both clinically and radiographically. The current report constitutes the 1-year data of a planned 5-year study. Materials and Methods: The study included a total of 177 patients treated with 590 NEOSS implants at 13 clinics in Sweden. The material was composed of 72 males and 105 females treated for single, partial, and total edentulism. Clinical, radiographic, and subjective evaluations were performed. Results: Out of 590 implants, 13 early failures have been reported, corresponding to a 1-year cumulative survival rate (CSR) of 97.8%. Evaluation of function and esthetics at the 1-year visit resulted in 100% success for function and 98% success for the esthetic outcome. The mean marginal bone loss was 0.6mm (SD 1.1) after 1year in clinical function. No adverse effects of the NEOSS dental implants were reported, and complications were few and similar to those reported for implant treatment in general. Conclusion: The CSR in the present study was 97.8%. No adverse effects of the NEOSS implants were reported, and complications during the study period were few and similar to those reported to for other well-documented implants system. Based on the present data, we conclude that NEOSS dental implant is a safe and predictable implant system. However, the high number of dropouts in the radiological evaluation must be considered when interpreting the data.

- Bone augmentation before treatment with endosseous implants is a common procedure for rehabilitation of the edentulous jaw. Both machined and surface modified implants have been used in one-stage and two-stage surgery protocols with varying results and survival rates. The influence of surface modification on the integration of implants has been documented in both non-grafted and grafted bone. The aim of this study was to compare the integration and stability of surface modified fluoridated vs. machined implants when placed simultaneously with an onlay bone graft.

- The relationship between oral health and Crohn's disease is uncertain. Previous studies have yielded contradictory results, reflecting perhaps the different phenotypes of the disease. The aim of the present study was to describe and analyse the dental status of a group of patients with Crohn's disease (CD), considering the positions of the inflammatory loci and disease phenotype.In total, 47 patients with Crohn's disease (18 males and 30 females; mean age. 48.7years; range, 23-61years) were consecutively recruited to this study. Interviews and clinical examinations were performed to assess dental status, medication, smoking history, heredity of inflammatory bowel disease (IBD), duration of disease, oral mucosal manifestations of Crohn's disease. Furthermore, data on subjective health assessments and family status, along with medical histories from the patients were obtained through questionnaires. The disease phenotypes were assessed and classified according to the Montreal classification. The data on oral health status were first correlated with the Montreal classifications of IBD, and, thereafter, all the collected data were included in a multivariate generalised linear model.The dental status of the patients was comparable to that of the Swedish average. No statistically significant associations were found between oral status and the different CD phenotypes. However, within the Montreal classification, there were significantly fewer teeth in those patients with perianal lesions than in those without such lesions, and there was a significant correlation between deeper pocket depth and problems with strictures and penetrations. No significant differences (p=.074) between the patients with CD (N=47) and controls (N=38) were found regarding the presence of oral mucosal lesions.Dental health may be adversely affected in severe cases of CD whereas most of the remaining patients with CD appear to have a level of dental health that is comparable to that in the general population.

- Background: The routine use of antibiotics in oral implant treatment seems to be widespread. The pre- or postoperative use of antibiotics in conjunction with implant surgery and its correlation with failure and success rates are poorly documented in the literature. The debate regarding overprescription of antibiotics raises the need for a critical evaluation of proper antibiotic coverage in association with implant treatment. Purpose: The purpose of this study was to compare the implant survival rate following a 1-day single-dose preoperative antibiotic regimen with that following a 1-week postoperative antibiotic protocol. Materials and Methods: The study included 868 consecutively treated patients. A total of 3,021 implants were placed. The population was split into two categories, either receiving a 1-day single-dose administration only, or a 1-week postoperative administration of antibiotics. Healing was evaluated at second-stage surgery (6 months for the upper jaw, 3 months for the lower jaw). Failure was defined as removal of implants because of non-osseointegration. Statistical analyses were performed with analysis of variance and the Scheffe test, with a significance level of 5% for comparison of data. Results: No significant differences with regard to complications and implant survival were found in the study. Conclusion: Based on the present data, a more restrictive regimen consisting of a 1-day dose of prophylactic antibiotic in conjunction with routine implant procedures is recommended.

- The objective of this study was to evaluate implant survival in reconstructed bone after the use of a synthetic bone substitute material (Calcium Sulphate). Clinical, radiological and histological parameters were studied in 25 patients. Unilateral and bilateral sinus augmentation was performed. An 80% + 20% mixed alpha hemihydrate Calcium Sulphate with autograph bone respectively was applied into the maxillary sinus. After six months, dental implants were installed. Prior to implant installation, all patients underwent a CT examination. In total 91 implants were inserted in all 25 subjects, 74 of these in augmented bone. Additionally, two micro-implants were installed bilaterally in 8 patients. After four months of healing, a third operation was performed to insert the healing abutments into the implants. Simultaneously, the micro-implants were retrieved for histological analysis. Implant stability was assessed through resonance frequency analysis at installation and at abutment connection. The pattern of bone formation in the experimental sites was investigated using histomorphometric measurements. Implant survival rate was 96,8% at abutment connection. The mean ISQ value at implant placement was 65.8 and at abutment connection 66,5. The mean bone to implant contact was 27,0%.

- Background Studies are inconsistent whether people with Crohn disease (CD) have an increased fracture risk. This study showed that patients with Crohn’s disease (CD) had a higher ten year probability of fracture, assessed by the fracture assessment tool FRAX, and more fractures, but the proportion of CD patients with a fracture was not significantly higher than that of controls. Methods Forty-nine CD and 49 controls participated. All 98 completed a health questionnaire. A score with the fracture assessment tool FRAX > 15% was considered risk factor for fracture. Results Mean FRAX score for 49 CD was 10.1 ± 10.3% and for 49 controls 5.0 ± 3.9% (P = 0.002). The variables correlated with fracture were being female (P = 0.04) and having a fractured mother (P = 0.002). Conclusion The CD group had significantly higher FRAX scores and more fractures, but the proportion of CD subjects with a fracture was not significantly higher than that of controls.

- OBJECTIVES: Crohn's disease (CD) is associated with reduced bone mineral density. The main objective of the present study was to assess the mandibular trabecular bone quality and to compare our findings with those among sex- and age-matched controls. Furthermore, background variables known to be significant for bone density were compared. MATERIALS AND METHODS: Intraoral radiographs of 49 Crohn's patients (23-61years old) and 49 age- and sex-matched controls were evaluated. Mandibular trabecular pattern was classified as either sparse, mixed dense plus sparse, or dense. Furthermore, two computer-based methods analyzed the transitions from trabecula to intertrabecular spaces and the size and number of these spaces. Differences in continuous background variables were tested with Student's two-sample t test and ordinal variables with Mann-Whitney U test or Kruskal-Wallis nonparametric tests. RESULTS: All three methods to evaluate bone structure seen on dental radiographs showed significantly sparser trabeculation in Crohn's patients than in the control group. The Crohn's patients were heavier, more often smokers, and more frequently had mothers who developed fragility fractures. Furthermore, the Crohn's patients, especially smokers, had a significantly higher fracture rate than the matched control group but no significant relationship was found between trabeculation pattern and fracture. CONCLUSIONS: The results of this investigations indicated that trabecular bone is significantly sparser in subjects with Crohn's disease compared to a matched control group. CLINICAL RELEVANCE: An early identification of CD patients with sparse trabeculation and appropriate advice concerning nutrition and exercise may lead to less fractures and medication in the future.

- Mandibular advancement was studied in 32 patients with mandibular retrognathia in whom the only intervention was in the mandible. Fifteen patients were treated with fixation by lag screws and 17 with monocortical miniplates. Lateral radiographs were taken preoperatively, postoperatively, 2 months postoperatively, and 1.5 years postoperatively, and mandibular movement analysed. All patients healed uneventfully. Cephalometric analysis of lateral radiographs showed no significant differences between the two groups in skeletal relapse during any of the control periods up to 18 months. Mandibular advancement for treatment of mandibular retrognathia using rigid fixation with either lag screws or miniplates was reproducable with only minor skeletal relapse.
