“…In particular, bone resorption significantly reduces available bone volume. The buccal mucosa becomes thinner and weakens, creating an additional difficulty for prosthetic tolerance 5. Under these conditions, the design of a conventional functional, removable complete denture becomes difficult or impossible.…”

BackgroundAdvances made in prevention have helped postpone complete edentulism in older patients. However, in the elderly, the physiological state reduces patients’ ability to adapt to oral rehabilitation and degrades the patient’s oral condition. Consequently, elderly edentulous subjects avoid many types of foods, which can lead to substantial nutritional consequences. Complete dentures retained by implants are, currently, the treatment of reference in prosthodontic mandibular rehabilitation. Indeed, the mandibular symphysis generally tolerates implantation, even when the mandible is strongly resorbed. However, in the elderly, implant rehabilitation is compromised by the complexity of the surgical protocol and possible postoperative complications. In this context, the use of geriatric “slim implants” (GSI) offers an interesting alternative.MethodsIn the present study, the surgical and prosthetic procedures for the use of GSI in a French dental hospital are presented. The objective was the stabilization of a complete mandibular denture in an elderly person, with the immediate implantation of four GSI.ResultsThe operating procedure was found to be less invasive, less expensive, simpler, and more efficient than the conventional procedure.ConclusionThe result strongly suggests that this protocol could be used systematically to treat complete edentulism in very elderly patients. Long-term monitoring and the evaluation of the reliability of this type of rehabilitation should be undertaken.

The aim of this study was to develop an experimental protocol to determine specific and reproducible biomarkers of the oral mucosa using a combination of thermal and vibrational techniques. This works deals with the characterization of mandible and maxilla biopsies, 4 mm by diameter, from porcine mucosa in both the hydrated and lyophilized state. Thermogravimet-ric analysis was carried out to measure hydration level of these tissues and to define the onset of proteins degradation. By differential scanning calorimetry, thermal transitions of water and proteins were evidenced and used to quantify the hydric organization (unfreezable/freezable waters) and to evaluate collagen thermal stability (through denaturation parameters). To complete this protocol, Fourier transform infrared spectroscopy was also used to identify specific vibrational signatures of the main layers of oral mucosa. Total and freezable water amounts are significantly higher in maxilla, due to morphological differences at the macroscopic level, while unfreezable water amount is independent upon localization. Denaturation temperature (in peculiar the temperature corresponding to 50% of collagen denaturation) largely increases with dehydration. This temperature denaturation is also dependent upon localization whatever the hydration, possibly due to differences in cross-links or interactions with other proteins of oral mucosa. The acquisition of thermal and vibrational biomarkers of oral mucosa will contribute to a better knowledge of these soft tissues for further studies on aging.
