PURPOSE Maxillary implant overdentures are often designed without palatal coverage to maximize wearer comfort. Although palateless dentures have been reported to be less rigid than conventional dentures, and require reinforcement to prevent complications, there is little documentation about the effects of such reinforcement. The purpose of this study was to examine the effects of reinforcement ...

AIM To examine the oral mucosa under the denture base and to determine the influence of local factors that contribute to denture stomatitis. METHODS In this prospective, case control study 30 patients with palatal inflammatory lesions were evaluated. A degree of palatal inflammation was scored. Swab samples were taken from tongue and palatal mucosa for microbiological examination. Denture pla...

OBJECTIVES Dentures are worn by around 20% of the population, yet if they become displaced they may enter the gastrointestinal or respiratory system, sometimes with grave consequences. The aim of this study was to review recent published literature in order to identify the epidemiology of patients and characteristics of swallowed and aspirated dental prostheses, and propose strategies to minimi...

OBJECTIVES This study evaluated the influence of prosthetic screw material on joint stability in implantsupported dentures at two levels of fit. METHODS Ten mandibular implant-supported dentures were fabricated. Twenty cast models were fabricated using these dentures. Four groups (n=10) were tested, according to the vertical fit of the dentures [passive and non-passive] and prosthetic screw m...

A nterior teeth are used directly to articulate some speech sounds, such as the consonants /f/ and /v/, and indirectly to produce other speech sounds, such as the consonant /s/. Thus, it is not surprising to find that prostheses or devices placed near teeth, or replacing teeth, alter speech production. In general the literature dealing with speech changes following dental treatment focuses on a...

Complete denture wearers often find it difficult to accept a new denture. Personality traits are among the factors that possibly affect patient satisfaction with a complete denture. Our aim was to investigate the influence of patients' personality on satisfaction with their present denture and after an increase in the occlusal vertical dimension (OVD). Sixty edentulous patients with complete de...

Bell's palsy is an idiopathic unilateral lower motor neuron paresis or paralysis of the facial nerve of sudden onset. It involves loss of muscular control on the affected side of the face. This paper reports the prosthodontic management of patients with Bell's palsy and also describes a technique to stabilize the jaw movements in complete denture patients using interim dentures. A 65-year-old m...

The purpose of this study was to investigate the retention force of complete palate coverage and palate-less dentures made with three polymerization systems (DS system, SR-Ivocap system, microwave polymerization system) in vitro. The retention force between each denture and a polyurethane model by intervening artificial saliva was measured using a tensile tester. In addition, discrepancies betw...

OBJECTIVES The aim of this study was to evaluate relationships between the socio-demographic and economic factors of patients and the reasons of admission, usage periods of the two types of clinics, frequencies of denture changes, satisfaction levels and preferences of prosthetic dental treatment. MATERIALS AND METHODS 510 partially and/or totally edentulous patients were studied using a ques...

The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then...
