Mortality in Edentulous Patients: A Registry-Based Cohort Study in Sweden Comparing 8463 Patients Treated with Removable Dentures or Implant-Supported Dental Prostheses

Objectives. The purpose of this study was to investigate if edentulism is associated with all-cause mortality. The aims were to analyze the association between age, socioeconomic factors, and mortality in edentulous patients treated with either removable dentures or implant-supported prostheses. Methods. All patients who became edentulous according to the Swedish Social Insurance Agency (SSIA) between 2009 and 2013 (N = 8463) were analyzed regarding prosthetic treatment, age, gender, and socioeconomic status. The patients were divided into two groups, depending on whether they were treated with dental implants (implant group; IG) or with conventional removable dentures (denture group; DG). Data on mortality for all included individuals were obtained from the Swedish National Cause of Death Register and compared to a reference population. Cumulative survival rates were calculated, and a multivariable regression analysis for the included variables was performed. Results. Between 2009 and 2018, 2192 of the patients (25.9%) were treated with implant-supported dental prostheses (IG) and 6271 patients (74.1%) were treated with removable dentures without support of dental implants (DG). Altogether 2526 patients (30%) died until December 31, 2019, and the overall mortality was significantly higher for the DG compared to the IG during follow-up ( p < 0.001 ). Younger edentulous patients (≤59 years) presented a higher mortality than the reference population, while implant patients over 79 years of age demonstrated a lower mortality. The final results from the multivariable logistic analysis showed that lower equalized disposable income (EDI) and the choice of conventional removable dentures are the most important factors for increased patient mortality ( p < 0.001 ). Conclusions. Edentulous patients have an overall higher mortality compared to a reference population. Low socioeconomic status increases all-cause mortality. Individuals treated with dental implants show statistically significant lower 10-year mortality compared to patients treated with conventional removable dentures, regardless of socioeconomic status.

Mandibular Overdenture

The aim was to systematically review the efficacy of immediate loaded mini dental implants (MDIs) to retain mandibular overdentures in regards to survival rates of MDIs, peri-implant clinical and radiographic tissue response and associated factors. A literature search of English literature was performed using Google Scholar, Scopus, Web of Science, MEDLINE (OVID), EMBASE, and PubMed using predetermined inclusion criteria. Specific terms were utilized in searching from the inception of the respective databases up to April 2021. The focused question was: Do immediate loaded MDIs supporting mandibular overdentures present favorable treatment options for prosthetic rehabilitation? The 11 articles included in the present review examined 349 patients (198 males + 171 females [66.65 ± 6.28 years]) in which 1190 MDIs were placed to retain mandibular overdentures. The mean follow-up duration was 24.5 months. The cumulative survival rate of MDIs was 97.3%. The mean scores of plaque index, gingival index, probing depth, and bleeding on probing ranged between 0–3, 0–3, and 1.203–1.76 respectively, whereas the mean marginal bone loss values ranged from 0.42 ± 0.56 mm to 1.26 ± 0.64 mm. The results identified that the application of immediate loaded MDIs to retain mandibular overdentures are a potential treatment modality for edentulous patients.

Aim. To evaluate the influence of primary insertion torque (IT) values of narrow dental implants on the peri-implant health, implant stability, immunoinflammatory responses, bone loss, and success and survival rates. Methods. Thirty-one edentulous patients received two narrow implants (2.9x10mm, Facility NeoPoros) to retain mandibular overdentures. The implants were categorized in four groups according to their IT: (G1) IT > 10 Ncm; (G2) IT ≥ 10Ncm and ≤ 30 Ncm; (G3) IT >30Ncm and < 45Ncm; (G4) IT ≥ 45Ncm, and all implants were loaded after 3 months of healing. The following clinical outcomes were evaluated 1, 3, 6, and 12 months after implant insertion: (i) peri-implant tissue health (PH), gingival index (GI), plaque index (PI), calculus presence (CP), probing depth (PD), and bleeding on probing (BOP); (ii) implant stability quotient (ISQ) by resonance frequency analysis; and (iii) IL-1β and TNF-α concentration in the peri-implant crevicular fluid. The marginal bone level (MBL) and changes (MBC) were evaluated. The Chi2 test, Kruskal-Wallis test, mixed-effects regression analysis, and the Kendall rank correlation coefficient were used for statistical analysis (α = 5%). Results. G1 presented the highest PD at all evaluated periods. G2 presented higher PI at month 6 and 12. G4 showed increased GI at month 3 and 12 and more CP at month 1 (p=.003). G2 and G4 had higher ISQ values over the study period, while those from G1 and G3 presented lower ISQ values. The IL-1β concentration increased until month 12 and was independent of IT and bone type; G4 had a higher IL-1β concentration in month 3 than the other groups (p=.015). The TNF-α release was negatively correlated with IT, and TNF-α release was highest in G1 at month 12. The MBL immediately after surgery and the MBC at month 12 were similar between the groups, and G4 presented a positive MBC at month 12. The survival and success rates were 75% for G1, 81.3% for G2, 64.3% for G3, and 95% for G4. Conclusion. The IT did not influence the clinical outcomes and the peri-implant immunoinflammatory responses and was weakly correlated with the narrow dental implants primary stability. The observed success rates suggest that the ideal IT for atrophic fully edentulous patients may deviate from the standardized IT of 32 Ncm.

e18173 Background: Follicular Lymphoma (FL) is a the second most common Non Hodgkin's Lymphoma (NHL) diagnosed in the United States with 2.6 per 100,000 men and women per year from 2011 to 2015 when age adjusted as per the National Cancer Institute with the number of deaths of 0.5 per 100,000 men and women per year. It known that FL is one of the most clinically indolent NHL and due to this, survival rates are generally more favorable when compared to other B Cell Lymphomas. With this study, we aim to analyse socioeconomic and racial disparities in the survival rates for FL. Methods: The authors identified patients diagnosed with FL between 1973 and 2015 using the Surveillance, Epidemiology, and End Results (SEER) database. Overall survival was estimated and compared between racial/ethnic groups using the log-rank test. Our outcome variables were 1-year, 5-year and mortality. Our independent variables were race and socioeconomic status. We controlled for age, demographic characteristics, time of diagnosis, pathological classification, treatment and socioeconomic status. Results: A total of 66 127 patients were identified; 90% of the patients were White, 4% Black, and 4% Asian. We noted significant differences in disease presentation, socioeconomic status, and outcomes. Asian/Pacific Islander had the lowest survival with a mean of 228 survival months, Blacks had a mean survival months of 237, and Whites had a mean survival months of 234. Conclusions: Disparities exist in the care and outcomes of FL. A low socioeconomic status is correlated with decreased survival.

Great Survival

The palatal coverage is considered as an auxiliary element in the distribution of tensile strains on implant maxillary total prosthesis (implant overdentures) bases, either implant-supported or retained. However, complaints in some patients due to palate and phonetic impairment are constant. The palatal coverage removal would allow the improvement of these issues as well as pharyngeal control, salivary flow and hygiene. Thus, this literature review proposed to analyze the survival rates of dental implants retaining an implant maxillary overdenture without palatal coverage in edentulous maxilla. The review was conducted in Medline database, via PubMed between 2000 to 2016 period, and limited to English language publications. The search strategy took the following key-words, referencing title and / or abstract: dental implants; maxilla; maxillary; overdenture; and palatal coverage. According the data, the rehabilitation of the maxillary edentulous with four implant-supported overdentures with bar attachments and implant-retained with ball attachments has shown great survival rates of dental implants, but there are a few studies reporting the survival rate of implant overdentures. It was concluded that the prosthetic rehabilitation of total maxillary edentulous patients is viable through palateless implant overdentures when a minimum of four to six implants were used with careful planning and execution.

Our purpose was to evaluate the occurrence of complications and the degree of bone loss in a cohort of patients treated with fixed prostheses supported by immediately loaded dental implants. The primary aim was to compare partial versus full-arch fixed dental prostheses. We then tested the effect of sinus lifting. In the present retrospective cohort study, the patients had their implants restored with fixed dental prostheses supported by dental implants positioned in the posterior maxilla and mandible. When necessary, the maxillary sinuses were grafted with particulate autogenous bone. Patients were then ranked according to the following predictors: length of prosthesis, crown-to-implant ratio, number of crowns to number of implants ratio, and presence of sinus lifting. Outcomes were evaluated for up to 2 years regarding the peri-implant marginal bone loss and implant/prosthesis survival rates. Fifty-eight subjects (209 implants) were rehabilitated with 25 fixed full-arch prostheses and 33 partial fixed dental implant bridges (16 supported by implants placed in grafted sinus). The mean marginal bone loss for implants supporting partial fixed dental prostheses amounted to 0.81 mm, whereas that for implants within the group of full-arch fixed dental prostheses was 1.21 mm; the comparison of the levels in the 2 groups showed a significant difference (P = .0055). A statistically significant difference (P = .0006) was found between the bone loss around maxillary implants (1.53 mm) and the bone loss around mandibular implants (1.10 mm). Two implants and 4 prostheses failed; 2-year survival rates of partial and of full-arch fixed dental prostheses, respectively, were 94.1% and 96%. Bone loss in full-arch prostheses appeared to be higher than in that of partial prosthesis. Implant-supported prostheses in the maxillae exhibited a bone loss higher than that registered in mandibles.
