Restauration prothétique amovible partielle et implantologie dans la qualité de vie orale des patients: revue narrative / Restoration of partial removable prosthetic and implantology in oral quality of life of patients: narrative review

L'association des implants aux prothèses amovibles partielles (PAP) ne sont pas bien perçues contrairement à la prothèse amovible complète. Cet article examine les connaissances actuelles sur la qualité de vie orale des patients porteurs de Prothèses amovibles partielles supra implantaires (PAPSI), en prenant en compte les performances cliniques, la comparaison des PAP versus les PAPSI et le taux de survie des implants. Les édentements mandibulaires en extension sont les plus concernés par les PAPSI avec une utilisation prépondérante de piliers axiaux. Le passage de la PAP à la PAPSI augmente de manière significative la satisfaction du patient. Le taux de survie des implants varie de 91.6% à 100% sur une durée de 2.5 à 7 ans. Au total, l'utilisation des PAP associée à des implants améliore la qualité de vie orale des patients. Des études cliniques prospectives sont davantage nécessaires pour évaluer cette approche.

The association of implants with partial removable prostheses (RPPs) is not well perceived in contrast to complete removable prostheses. This article reviews the current knowledge on the oral quality of life of patients with supra-implant removable partial dentures (SIRPDs), considering clinical performance, comparison of RPPs versus SIRPDs and implant survival. Extended mandibular edentulous teeth are the most concerned by PAPSI with a preponderance of axial abutments used. The switch from RPDs to SIRDs significantly increases patient satisfaction. The survival rate of the implants varies from 91.6% to 100% over a period of 2.5 to 7 years. Overall, the use of RPPs in combination with implants improves the oral quality of life of patients. More prospective clinical studies are needed to evaluate this approach.

Effects of wearing removable dentures and aging on palatal mucosa blood flow by laser doppler.

Aim: The purpose of this work is to analyze the effects of removable dental prostheses and aging on blood microcirculation in the palatal mucosa. Settings and Design: Blood flow was measured in two groups using the Laser Doppler Flowmeter at three specific anatomical sites: Retro incisive papilla, medial raphe, and Schroeder area. Materials and Methods: Group 1 included young, healthy dentulous individuals (mean age: 23 ± 3 years), and Group 2 contained elderly edentulous individuals (mean age: 62 ± 11.69 years). For Group 1, measurements were taken in a single session; for Group 2, the measurements were taken in two sessions: The first just before the prosthetic load (E1) and again 1 week after new dentures were provider (E2). Statistical Analysis Used: Statistical analyses were performed using SAS software, Version 9.4 of the SAS System for Windows, Copyright © 2017 SAS Institute Inc. (Cary, NC, USA). A P < 0.05 was classified as statistically significant. Results: Measurements of blood flow of the palatal mucosa showed that the healthy young dentulous participants had significantly lower perfusion unit values than the elderly edentulous participants at all three anatomical sites (P < 0.05). For Group 2, the comparisons between the measurements taken before (E1) and after (E2) new dentures were provided showed no significant differences. Conclusion: Our results indicate that the process of aging significantly modifies the blood flow of the palatal mucosa while wearing removable dental prostheses does not modify the blood flow of the palatal mucosa in a 1week period. These results are not influenced by systemic pathology (e.g., diabetes, cardiovascular diseases) or smoking.

The use of laser Doppler flowmetry to evaluate oral soft tissue blood flow in humans: A review.

The objective of this work is to define the conditions for improving the use of laser Doppler flowmetry (LDF) and to determine the limits for the use of this technique. This article systematically reviews the literature on the evaluation of oral soft tissue blood microcirculation by LDF. We analysed the available literature through October 2016 using the database resources Medline/PubMed, the Cochrane Oral Health Group Specialist Trials Register and the ISI Web of Knowledge. Several points emerged from this literature review The use of LDF involves specific constraints; however, the influence of different factors (temperature, tobacco, pressure etc.) must be adequately controlled when using LDF. LDF measurements of soft tissue within the oral cavity vary depending on the anatomical site. In dentistry, LDF can be used to track healing progress in periodontal surgery and to diagnose vascular flow changes in the connective tissue of mucosae covered by a removable prosthesis at an early stage prior to the onset of clinical inflammation signs.

Pilot Study of Laser Doppler Measurement of Flow Variability in the Microcirculation of the Palatal Mucosa.

Background. Histopathological alterations can arise when the denture-supporting mucosa experiences microbial and mechanical stress through the denture base and diagnosis of these diseases usually follows microvascular changes. Microcirculation measurement could allow for detection of such dysfunction and aid in the early diagnosis of palatal mucosa pathologies. Materials and Methods. We tested the sensitivity of laser Doppler for measuring the microcirculation of the palatal mucosa, assessing the median raphe (MR), Schroeder area (SA), and retroincisive papilla (RP). A Doppler PeriFlux 5000 System, containing a laser diode, was used. 54 healthy participants were recruited. We compare the measurements of PU (perfusion unit) using ANOVA test. Results. The numerical values for palatal mucosa blood flow differed significantly among the anatomical areas (p = 0.0167). The mean value of Schroeder area was 92.6 (SD: 38.4) and was significantly higher than the retroincisive papilla (51.9) (SD: 20.2) (p < 0.05), which in turn was higher than that of median raphe (31.9) (SD: 24.2) (p < 0.0001). Conclusion. Schroeder area appeared to have the greatest sensitivity, and vascular flow variability among individuals was also greatest in this region. We suggest that analysis of blood stream modification with laser Doppler of the palatal mucosa can help to detect onset signs of pathological alterations.
