Tongue Pressure Recording During Speech
This research is about tongue’s pressure during speech,
using a complete denture which allows respecting tongue and
speech physiology at the best.
A strain gauge transducer is placed inside this prosthodontics
device. During speech, the pressure and the sounds are
recording. The analysis of the twos signals should explain what
pressure is needed for what sound. The comparison between old
complete denture wearers and new one is realized to provide
informations about tongue adaptation’s phenomenon.

Article: Resin-bonded fixed partial dentures: what's new?

BACKGROUND AND OBJECTIVE: Dentists often question the use of
resin-bonded fixed partial dentures (RBFPDs) for reliable
restoration of tooth-bound edentulous spaces. Initial attempts
at bonding fixed partial dentures on teeth resulted in early
failure due to debonding. In the 1980s and 1990s, improvements
in preparation methods, metal alloys and bonding techniques made
the RBFPD a more predictable option. In this paper, we summarize
recent information concerning its success and failure. METHODS:
A MEDLINE search using key words describing RBFPDs was carried
out to identify pertinent English articles appearing in
peer-reviewed journals since 2000. RESULTS: The principle reason
for failure of RBFPDs remains debonding of the framework from
the abutment teeth. Selection of nonmobile abutment teeth,
preparation to enhance retention and resistance form, choice of
the appropriate alloy and metal, and tooth bonding technique are
the keys to success. The use of cantilever and nonrigid
attachments may decrease interabutment forces and reduce
debonding of retainers. CONCLUSIONS: The survival rate of RBFPDs
is still considerably lower than that of conventional fixed
partial dentures. Although RBFPDs can be used in both the
anterior and posterior regions of the mouth to replace 1 or 2
missing teeth, careful abutment selection, tooth preparation,
alloy selection and bonding technique are critical for clinical
success.

PURPOSE: The aim of this retrospective study was to evaluate implant survival rate, peri-implant conditions, and prosthodontic maintenance for implant-supported mandibular overdentures rigidly retained with a milled bar. MATERIALS AND METHODS: Patients with 4 interforaminal implants (cylindric or screw-type) supporting an overdenture on a milled bar treated between 1996 and 2004 were asked to participate in a retrospective study. The cumulative implant survival rate and peri-implant conditions (marginal bone loss, pocket depth, Plaque Index, Gingival Index, Bleeding Index, and calculus presence) were evaluated and compared between cylindric and screw-type implants. The incidence and type of prosthodontic maintenance and subjective patient satisfaction rating were also evaluated. RESULTS: Fifty-eight of 67 patients (87.3%) and 232 implants (76 cylindric, 156 screw-type) were available for follow-up examination after a mean period of 59.2 +/- 26.9 months. The cumulative implant survival rate was 99%, and no differences in peri-implant soft tissue conditions were noted between the different implant types used. The cylindric implants showed more pronounced marginal bone resorption than the screw-type implants (1.9 +/- 0.6 mm vs 2.2 +/- 0.6 mm; P = .02) but the difference was not clinically significant. A low incidence of prosthodontic maintenance evenly distributed throughout the overall follow-up period and a high subjective satisfaction rating by the patients were noted. CONCLUSION: Interforaminal screw-type and cylindric implants supporting a milled bar for rigid overdenture anchorage were associated with a high survival rate and excellent peri-implant conditions. The incidence of prosthodontic maintenance was low and evenly distributed throughout the follow-up period as a result of rigid denture stabilization by the milled bar. Rigid anchorage of a mandibular overdenture with a milled bar unites the prosthodontic advantages of removable and fixed prostheses. (Clinical Trial) (More than 50 references.)

STATEMENT OF PROBLEM: Occlusal disharmony due to processing can cause discomfort to the patient. PURPOSE: The purpose of this investigation was to identify whether refinement in occlusion was correlated with patient comfort and the number of postinsertion visits. MATERIAL AND METHODS: Maxillary and mandibular complete dentures were fabricated for 30 subjects who were randomly divided into 3 groups of 10 subjects using a lottery: Group LCRO, the control group, received both laboratory and clinical remount procedures along with occlusal corrections; Group LRO subjects received only laboratory remount with occlusal corrections; and Group OOC subjects underwent routine procedures in complete denture construction without remount corrections and only occlusal corrections where required, intraorally. A pilot study was conducted to identify the feasibility of a close-ended questionnaire designed by the investigator and containing 5 questions regarding the comfort, pain, masticatory ability, swallowing, and occlusal contacts of maxillary and mandibular complete dentures. The evaluation was performed following the subject's use of the dentures for 7 days. All 30 subjects were examined for tissue irritation at this time. The evaluation was conducted by a single examiner who was unaware of the groups to which the subjects belonged. An analysis of statistical difference between the treatment groups for the number of postinsertion visits, comfort, pain during mastication, swallowing, and areas of tissue irritation during use of complete dentures was assessed using the chi-square test and Kruskal-Wallis test (alpha =.05). RESULTS: The results indicated that remount procedures and occlusal corrections significantly reduced the number of postinsertion visits (Kruskal-Wallis test, P<.001). There was less pain during mastication in group LCRO compared to the other groups (Kruskal-Wallis test, P=.0399). Group LCRO subjects also reported less incidence of tissue irritation compared to group LRO and group OOC (chi2=18.26, P<.001) CONCLUSIONS: The combination of laboratory and clinical remount procedures with occlusal corrections enhanced patient comfort, compared to the other groups in which either one or both of the procedures were not performed.

OBJECTIVES: A systematic review identified randomised and other trials (1966-2006) of studies of occlusal design of crowns, complete (CRP) and partial (PRP) removable prostheses and implant-borne reconstructions, and whether occlusal design influenced diet, quality of life, bruxism and attrition. METHODS: The search primarily included Cochrane Database of Systematic Reviews and Central Register of Controlled Trials, Database of Abstracts of Reviews of Effectiveness, Ovid Medline and PreMedline. RESULTS: The search yielded 1315 studies: 20 on CRP--1 RCT, one systematic review, four clinical trials, 10 case series; 22 on PRP - one cohort study, two experimental studies, 15 case reports or case series, three clinical trials; 23 on implant superstructures, and 24 reports on implant failure, 37 on oral health related quality of life, eight on attrition; and four studies on masticatory function. CONCLUSIONS: CRP--Studies of occlusal form and tooth arrangements, included balanced, lingualised and monoplane arrangements--lingualised posterior occlusion was preferred. Early studies on CRP design were observational as case reports, however data suggested that optimum function is achieved by modification of the maxillary occlusion, irrespective of the opposing mandibular occlusion. PRP--Edentulous ridge resorption is patient-specific, has a multifactorial aetiology and there is no objective data to confirm that mechanical factors cause bone loss; oral hygiene management is crucial for long-term health. Studies on distal extension PDs confirmed a link between bite force and masticatory function; preservation of two functioning posterior tooth units ipsilateral to the distal extension optimises function. Data indicate that patient-specific factors, rather than PD design-specific features, influence long-term PD outcomes. Implant superstructures--There is little scientific evidence specifying occlusal and superstructure design for fixed prostheses for teeth or implants. Occlusal scheme design and occlusal form have evolved through clinical experience, but there is no evidence to indicate that a particular design is superior. Complex neurophysiological mechanisms allow the jaw muscle system to accommodate to oral and dental changes.
