Do implant-supported prostheses affect bioavailability of nutrients of complete and partially edentulous patients? A systematic review with meta-analysis

Free flap jaw reconstruction with dental implantation: A single-institution experience

BACKGROUND

We sought to review our institution's experience with dental implant placement in free flap jaw reconstruction to determine factors impacting restoration of dental occlusion.

METHODS

Exactly 48 patients underwent free flap jaw reconstruction with or without dental restoration from 2017 to 2022. Primary outcome was achievement of restored dental occlusion after jaw free flap reconstruction.

RESULTS

A total of 48 patients with a mean age of 59.8 ± 16.4 years underwent jaw reconstruction from 2017 to 2022. Ten patients (20.8%) received osteointegrated dental implants. Two patients received a temporary dental prosthesis, 12 ± 4 months after initial reconstruction. Three patients received a final prosthesis, with a mean time to final prosthesis of 17.7 ± 12.4 months. Five patients did not receive any prosthesis despite placement of implants.

CONCLUSION

A minority of patients received dental implant placement with free flap jaw reconstruction and only a small subset of these received a definitive dental prosthesis.

Risk factors associated with implant sites prepared by orthodontic treatment: a systematic review

The patient's health and quality of life would probably be improved with dental implant. This study aimed to evaluate the risk factors associated with dental implants place by orthodontic treatment. In this study, information on risk factors associated with implants of sites prepared, radiology stereotypes and hospitalized were obtined from databases such as Scopus, Google scholar and PubMed, and 58 articles were included for this purpose. After analyzing the articles, 24 articles were not accepted and 34 articles were accepted, then, 16 articles were miscarriage and 18 articles were scientific sources. The results showed that orthodontic treatment has a significant effect on a person's sense of beauty and would possibly increase self-confidence and quality of life. The stability of the implant in the healing phase depends on the quality and quantity of the bone. Also, the width of the bone is one of the important issues in creating a successful treatment. When an implant fails, problems and symptoms of failure usually occur within the first year after surgery. After one year, there is only about a 1% chance of failure, and on average only 1% of all implants fail each year.

Teeth Rehabilitation and Nutritional Influence on Diabetic Patients: A Review

Diabetes mellitus (DM) is a globally prevalent endocrine and metabolic disorder characterized by hyperglycemia. Its complications significantly impact both the quality and longevity of the patient's life with a substantial burden on the healthcare system. Missing teeth make individuals more susceptible to malnutrition compared to those with functional teeth. This is especially true for people with diabetes, as the condition is closely linked to both oral health and food intake. Natural teeth loss can significantly reduce an individual's ability to chew food, leading to a decrease in the quality and quantity of their nutrition. Prosthodontics is a dental specialty that replaces missing teeth with artificial ones. Replacing missing teeth may prevent the risk of malnutrition due to decreased ability to chew. Good oral health is important for overall health, especially for those with conditions such as diabetes. Artificial teeth replacement may improve nutrition intake by improving chewing ability. Therefore, the ultimate objective of rehabilitating a patient's oral cavity is to replace the shape and function in terms of chewing performance to a degree that is as close to normal as feasible. The purpose of this review is to explore the literature showing the link between natural teeth loss and nutrition in individuals with DM, with a special focus on prosthodontic management. Several oral complications occur in diabetic patients specifically teeth loss, which in turn affects mastication function. This in turn cause malnutrition and affect glucose level. It is imperative for healthcare providers to take an interdisciplinary approach in order to improve the dental and nutritional status and overall well-being of DM patients.

Effect of dentures and dietary advice on protein intake in older Thai adults with missing posterior occluding teeth

OBJECTIVE

To compare the effectiveness of dentures with dietary advice and dentures alone on protein intake in older Thai adults.

BACKGROUND

Dentures combined with nutritional advice may improve protein intake in older adults with posterior tooth loss. However, evidence is limited, especially in developing countries.

METHODS

A randomised-control trial including 69 older adults with less than four pairs of posterior occluding teeth was conducted for 3 months. The experimental group received dentures and dietary advice based on the Health Belief Model (HBM); the control group received dentures alone. Three-day dietary records were collected and protein intake was assessed using INMUCAL-NUTRIENTS V.4.0 software at baseline, 1 month, and 3 months after the intervention. Data were analysed using a t-test, Mann-Whitney U test, chi-square test, and repeated-measure ANOVA.

RESULTS

Both groups reported significantly increased protein intake (control group = 0.4, 0.5, 0.6 g kg BW-1  d-1 , intervention = 0.4, 0.6, 0.7 g kg BW-1  d-1 , at baseline, 1 month and 3 months, respectively). However, participants in the experimental group had significantly higher total protein (36.3 vs. 39.8 g/d, P = .032) and animal protein intake (18.9 vs. 23.2 g/day, P = .020) than those in the control group at 3 months after the intervention; plant protein intake was similar (10.9 vs. 11.5 g/day, P = .923). In addition, the HBM scores of the experimental group were higher than those of the control group after the intervention (P < .001).

CONCLUSION

Dentures combined with dietary advice significantly increased the total and animal protein intake of older people with posterior tooth loss more than dentures alone. To maintain optimal protein intake, dental practitioners should incorporate dietary advice when providing dental prostheses to older adults with posterior tooth loss.

Removable partial dentures and mortality among partially edentulous adults

OBJECTIVES

The aim of this study was to evaluate whether the use of removable partial dentures (RPDs) has an effect on long-term survival outcomes amongst partially edentulous adults.

METHODS

Data were extracted from the Third National Health and Nutrition Examination Survey and linked to public-use mortality files for the period up to 2019. Partially edentulous adults with fewer than 20 teeth were included. RPD use and dentition status were determined by clinical examination. The cohort was propensity score weighted to create a sample which was balanced across 27 covariates (sociodemographics, health behaviors and insurance, laboratory markers, and general health status). Survival analysis was undertaken to compute absolute (mortality rate and median survival time) and relative (event time ratio [ETR]) measures of exposure effect.

RESULTS

The analyzed cohort included 1246 participants, which equated to 22,557 person-years of follow-up. The difference in all-cause mortality rate between RPD wearers and non-wearers was found to be -6.5 (95% CI: -11.6 to -1.4), with the median survival time in RPD wearers being 3.1 years longer (20.3 years versus 17.2 years). A 26% increase in survival time was observed in RPD wearers (ETR: 1.26, 95% CI: 1.17 to 1.37) and it was found that, for every 7.5 individuals treated with RPDs, one death would be prevented after 10 years of treatment.

CONCLUSIONS

The use of RPDs may have long-term benefits in reducing mortality amongst adults with a non-functional dentition, but further research is needed to validate these findings and assess the factors mediating the relationship.

CLINICAL SIGNIFICANCE

The use of RPDs may have long-term benefits in reducing mortality amongst adults with a non-functional dentition.

Prognosis of Implants with Implant-Supported Fixed Dental Prostheses in the Elderly Population: A Retrospective Study with a 5- to 10-Year Follow-Up

This retrospective study aimed to investigate the survival rate of implants from 5 to 10 years after the placement of implant-supported fixed dental prostheses (ISFDPs) and the management of implant loss in the elderly population. Elderly patients (≥65 years old) who had been treated with ISFDPs and followed up with for at least 5 years between October 2009 and March 2020 were enrolled. Patient profiles and implant-related data were extracted. The survival rate of implants up to 5 years as well as the 10-year cumulative survival rate were evaluated. The management of implant loss and prosthetic interventions were also investigated. In total, 195 patients (mean age: 70.1 ± 4.5 years old) and 687 implants (287 ISFDPs) were assessed. The 5-year survival rate was 99.0% and the 10-year cumulative survival rate was 98.1%. Seven of the eleven implants lost were lost due to peri-implantitis. Only three implants in two patients were placed after the loss of the implants; most were restored using non-invasive procedures. Two patients underwent a conversion from ISFDPs to removable prostheses. This study showed that high survival rates were observed in an elderly population with ISFDPs and that non-invasive procedures were often applied after the loss of an implant.

Effects of Dental Implants and Nutrition on Elderly Edentulous Subjects: Protocol for a Factorial Randomized Clinical Trial

Background

Loss of masticatory function consequent to tooth loss has been associated with changes in food choices and insufficient nutritional intake. To date, interventions based on dental prostheses alone did not significantly improve nutrient intake. Pilot studies have shown positive impacts of interventions combining implant-supported fixed dental prosthesis with brief dietary advice. The relative contribution and the potential synergy of the components of such interventions need to be determined as it has major public health implications for the community-dwelling aging population that continues to disproportionately suffer from tooth loss and its consequences.

Objective

To assess the effect of rehabilitation of masticatory function with fixed implant supported dentures and nutrition education in older subjects with terminal dentition (stage IV periodontitis) or full edentulism.

Methods

A 2 × 2 factorial randomized controlled trial with 16-month follow-up of eligible adults (≥60 years) with loss of masticatory function consequent to full arch edentulism or terminal dentition (n = 120) will be conducted to test whether the rehabilitation of masticatory function with fixed implant supported dentures, nutrition education and/or their combination improves intake of fresh fruits and vegetables for aging subjects. The study has been designed to detect changes in fresh fruits and fresh vegetables intake at 4 months using the 24-h dietary recall method. Changes in protein as percentage of total energy, nutritional biomarkers, plasma metabolomics, oral and gut microbiome, quality of life and masticatory function will also be assessed.

Discussion

We hypothesize that receiving rehabilitation of masticatory function with fixed implant dentures together with nutrition education is the most effective intervention for improving nutrient intake in aging community-dwelling subjects with extensive tooth loss. The results of this study will assist in designing better treatment regimens, guide medical care for individual subjects, and inform public health and policy.
