RESUMO
Pathologies in peri-implant tissues are common and may disturb long-term implant supported rehabilitation. We aimed to evaluate the occurrence of such peri-implant diseases and their associated factors in this study. Peri-implantitis and mucositis were diagnosed based on clinical and radiological findings. Statistical analysis was performed with the X2 and logistic regression. Peri-implant mucositis and peri-implantitis were observed in 43.4% and 13.8% of patients with implants evaluated, respectively. Univariate analysis found associations with systemic changes (P = .016; yes), medication use (P = .010; yes), implant location (P < .0001; upper jaw), implant region (P = .008; posterior), previous augmentation procedure (P = .023; yes), time of prostheses use (P < .0001; >2 years), keratinized mucosa (P < .0001; absence); and gingival bleeding index (P = .005; >30%). In the multiple analysis, independent predictors were: >2 years of prostheses use (P < .0001; PR = 1.720), upper jaw location (P < .0001; PR = 1.421), gingival bleeding index >30% (P = .001; PR = 1.496), and use of medication (P < .0001; PR = 1.261). The frequency of peri-implant pathologies is high (approximately 57.2%) with several aspects of the occurrence being related to the patients' prosthesis. Prostheses type and the complexity of rehabilitation are worth highlighting. Factors include the location of the dental implant, gingival bleeding index, patient's use of medication(s), and the time of prostheses use.

The aim of this observational study was to assess the degree of patient satisfaction toward implant-supported prostheses. A questionnaire was used with two scales (one consisting of detailed adjectival and the other of numerical responses) regarding chewing, esthetics, speaking, comfort and overall satisfaction. The scales were administered to a sample of 147 patients treated with implants and prostheses. The data were submitted to the Kappa statistic and the Chi-square test to analyze the association between dependent and independent variables. High degrees of satisfaction (greater than 91%) were found for all categories evaluated, regardless of gender, age, number of implants or type of prosthesis. “Comfort” was associated significantly with the number of implants (p = 0.038), and “speaking” was associated significantly with the type of prosthesis (p = 0.029). Positive agreement was found between the scales for all categories evaluated, without statistically significant differences regarding respondent preference (p = 0.735). Patients treated with implant-supported prostheses were highly satisfied with the treatment.

OBJECTIVES: This study aimed to systematically evaluate the long-term results of periodontal tissues in regenerated infrabony and furcation defects. MATERIAL AND METHODS: A search of the Medline database was performed (1960 to 2012), complimented by an additional hand search. For inclusion in the review, clinical trials had to include the long-term evaluation of infrabony and furcation defects submitted to periodontal regeneration for up to 3 years of follow-up. Changes in clinical attachment level (CAL) from pre-surgery, at the first post-surgical, and final evaluations were used to analyze the effects of regenerative treatments over time. RESULTS: A total of 866 articles were found using the descriptors employed. Of these, 216 papers were selected for abstract reading by two evaluators. One hundred and eighty-nine were excluded for not fulfilling the eligibility criteria. Twenty-seven papers were selected for the analysis of the full texts, and 13 were excluded. Two studies were included after a manual search. Finally, 16 papers were selected for the present review. CONCLUSIONS: Regenerative techniques for the treatment of infrabony and furcation defects resulted in improved CAL during long-term follow-up periods, even when attachment losses occurred during this period. This improvement should be carefully evaluated with regard to its clinical relevance for dental longevity. CLINICAL RELEVANCE: The improvement in clinical attachment level achieved by regenerative techniques with biomaterials demonstrated satisfactory results over the long-term. However, regenerative techniques still present different success rates with regard to gain in clinical attachment level.
