RESUMO
Background: This study aims to show the clinical outcomes of implants supporting mandibular overdentures in edentulous patients. Methods: Mandibular edentulous patients were diagnosed with an oral examination, panoramic radiograph, and diagnostic casts for intermaxillary relations and treated with overdentures over two implants. After two-stage surgery, implants were early loaded with an overdenture at 6 weeks. Results: Fifty-four patients (28 females and 24 males) were treated with 108 implants. Thirty-two patients (59.2%) had a previous history of periodontitis. Twenty-three patients (46%) were smokers. Forty patients (74.1%) suffered from systemic diseases (i.e., diabetes, cardiovascular diseases). The clinical follow-up of the study was 147.8 ± 10.4 months. The clinical outcomes showed a global success of 94.5% of implants. Fifty-four overdentures were placed in the patients over the implants. The mean marginal bone loss was 1.12 ± 0.34 mm. Nineteen patients (35.2%) showed some kind of mechanical prosthodontic complication. Sixteen implants (14.8%) were associated with peri-implantitis. Conclusions: Based on the clinical results obtained, we can determine that the treatment of elderly edentulous patients with mandibular overdentures through the early loading of two placed implants is a successful implant protocol.
RESUMO
BACKGROUND: Dental consultation may provoke stress to the patient, especially when a dental surgery is going to be performed, stressful situations can cause a reaction in the sympathetic nervous system that could lead to cardiovascular alterations. Blood pressure and cardiac frequency are used often as an indirect measurement and this parameters combined can serve as good indicators of stress. Objective: Analyze the changes in vital signs and analytical parameters induced by a dental extraction. MATERIAL AND METHODS: 24 healthy patients who required a simple dental extraction underwent to a blood test and motorization of their pre- and post-extraction vital signs before, at 2 and 48 hours after the procedure. Data analysis was performed by means of repeated measures one way ANOVA followed by multiple comparisons Bonferroni's Post-hoc test. RESULTS: The evaluated patients were 13 women and 11 men with an average age of 35.1. Thirteen patients (54.17% of the sample) were smokers and five were regular drinkers (20.8%). No significant differences were observed in the vital signs with the exception of diastolic blood pressure and cardiac rate that were slightly lower after extraction. Only two analytical parameters showed statistical significant changes. Total bilirubin was significantly higher at 48 hours after extraction and leukocyte count was significantly lower at this time. In any case, the magnitude of the changes observed was very low. The analytical parameters and the vital signs did not show any relevant change. CONCLUSIONS: Eventual alterations found after simple tooth extraction should not be attributed to the procedure. Key words:Blood pressure, heart rate, monitoring physiologic, oxygen saturation, tooth extraction.
RESUMO
OBJECTIVE: Oral nerve injuries are a less frequent complication but they involve a decrease in the patient life quality. The purpose of the current review is to know the described risk factors to prevent injuries and to know the therapies against an established injury. MATERIALS AND METHODS: A Pubmed search of the English and Spanish language literature from 2000-2012 using the keywords 'oral surgery' or 'trigeminal nerve injuries' or 'lingual nerve injuries' or 'mandibular nerve injuries' was performed. Review articles were included and important articles from the references were added. RESULTS: A total of 662 were obtained from the search, from which 25 were selected accomplishing the inclusion criteria. Moreover, seven important articles were selected from the references of the ones mentioned, obtaining a total of 32 articles for the review. CONCLUSIONS: There is a relationship between the position of the extracted tooth and the incidence of the inferior alveolar nerve and lingual nerve injuries; as well as the age of the patient, the intra-operatory exposition of the nerve, the technique access for the lower third molar extraction and the surgeon's inexperience. The radiological examination is useful to evaluate the nerve damage and to decide on the surgical technique.
