Eligibility

Inclusion criteria

Inclusion criteria: It will be selected 18 elderly over 60 years old, according to the following inclusion criteria: to be totally edentulous in the upper and lower dental arches, and to use upper and lower dentures for at least 1 year; to have posterior mandibular alveolar process sharply reabsorbed, with height less than or equal to 15 mm³,and lower anterior alveolar ridge compatible with the implant, and with a minimum bone volume of 8 mm, condition detected after radiographic examination and / or tomographic; to be a Portuguese native speaker and finally to be literate.

Exclusion criteria

Exclusion criteria: The elderly with parafunctional habits; craniofacial malformation; moderate to deep hearing loss (evaluated by tonal audiometry), which are users or not of any individual sound amplification apparatus; cognitive impairment (evaluated through the application of the Mini Mental State Examination) ; aged with some language disorder; aged with severe speech disorder; elderly already done laryngeal surgery; aged who had experience with speech evaluations and with psychophysical; elderly with symptoms of temporomandibular joints and / or chewing muscles; aged with uncontrolled systemic diseases; neurological diseases, such as: ischemic or hemorrhagic stroke, traumatic brain injury, Parkinson's disease, Alzheimer's disease; elderly with psychiatric disorders which change the articulation of speech and the course of this study; smokers; alcoholics; aged who have performed head and / or neck irradiation due oncological diseases will be eliminated of this study.

Design outcomes

Primary

MeasureTime frame
It is expected that the patients have higher Percentage of Correct Consonants when rehabilitated with mandibular overdentures compared to rehabilitation with new conventional dentures. The evaluation of phonoarticulatory characteristics will be performed by a speech pathologist, specialist in Orofacial Motricity. This professional will be blind in relation to the prosthetic treatment of the patients. Three speech samples will be collected from each volunteer through audio and video recording. These samples will be collected as follows: (1) during spontaneous speech, (2) speech corresponding to the count of numbers, and (3) during repetition of pre-determined words and phrases. The 3 speech samples will be recorded through a semiprofessional camera, positioned in front of the individual, on a tripod, 1m away from it. The recordings will be transferred to a Samsung Expert notebook model NP270E5K, Intel® Core ™ i5 (2.2 GHz, 1600 MHz, 3 MB L3 Cache). Speech records will be scanned and recorded on DVD-R. These records will be guided by the speech pathologist specialized in Orofacial Motricity. The spontaneous speech wil be collected as follows: the volunteers will be recorded participating of a conversation guided by the following questions of reference: "Do you like any sport?", "What do you like to watch on television?", "Tell me about your day " , "What kinds of songs and singers do you like?" "When you talk to people you know or unknow, do they understand what you are talking about?", "Do you have any difficulty talking to the dental prostheses ?" and " Do you avoid socializing because of your way of speaking? The speech sample during repetition of words and phrases will be recorded with the participants repeating a list of words and phrases, containing all the phonemes of the Brazilian Portuguese language in different positions. Finally, the elderly will be instructed to count from 0 to 20 and from 60 to 70. This speech sample will also be recorded through

Secondary

MeasureTime frame
It is expected to be noted in the final phase of this research, in which patients will be rehabilitated with mandibular overdentures, increase of speed and decrease of mandibular movements amplitude, compared to rehabilitation with new dentures. The recording of mandibular movements pattern during speech and free-way space of pronunciation will be colected by the electromagnetic method, using JT3D Jaw Tracker Biopak® (BioResearch®, Miwaukee, USA). The use of this equipment will allow the monitoring and recording of the spatial position and the trajectory of the mandibular movements through a set of electromagnetic sensors. These sensors capture the movements of a magnet temporarily fixed in the vestibular region of the lower central incisor teeth of the prostheses of the volunteers, so as not to interfere with the position of maximum habitual intercuspation. This equipment will be connected to a computer compatible with the installed program of electrognatographic interpretation, in which the "speech" function will be selected. It will allow the recording of mandibular movements during speech in three planes: sagittal, frontal and horizontal. The evaluation will be performed with the volunteer sitting in a dental chair and positioned with the Frankfurt plane parallel to the ground. In the glabella region, the antenna support will be positioned with the nasal support and the upper rod should be parallel to the inter-pupillary line. The lateral stems will be positioned above the ears, parallel to the ground, and adjusted by the strip positioned in the posterior region of the head. Patients will be instructed to close the mouth in position of maximum habitual intercuspation. This position will be explained and demonstrated before the beginning of the records. Next, the volunteers will be instructed to sequentially and uninterruptedly name images found in a list of easily understood figures. The list contains all the phonemes of the Brazilian Portuguese langu
