Impact of mandibular conventional denture and overdenture on quality of life and masticatory efficiency

Abstract 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 assigned to either two treatment groups: mandibular overdentures supported by two implants with bar-clip system and a maxillary conventional denture (n = 25), and new maxillary and mandibular conventional complete dentures (n = 25). Masticatory efficiency and oral health-related quality of life were assessed before and 3 months after denture insertion. The Brazilian version of OHIP-Edent questionnaire was used to assess the oral health-related quality of life. Masticatory efficiency was evaluated with chewing capsules through a colorimetric method. The results revealed fewer oral health-related quality of life problems in patients wearing mandibular two-implant overdentures compared to the conventional dentures group. In addition, the implant overdenture group presented statistically significant improvement in masticatory efficiency (p = 0.001). There was no correlation between masticatory efficiency and OHIP in the implant group (p > 0.05), however a correlation was found in the conventional denture group (p < 0.05). Therefore, these short-term results suggest that mandibular overdenture retained by 2 implants with immediate loading combined with maxillary conventional dentures provide better masticatory efficiency and oral health-related quality of life than mandibular conventional dentures.

Trends, awareness, and attitudes of patients towards replacement of missing teeth at University College of Dentistry

This study was carried out among the out patients seen in the University College of Dentistry [UCD] with the aim to assess their trends and attitudes towards tooth replacement. Patients with at least one missing tooth [excluding the third molars] were included. The study was conducted using a questionnaire. Majority of the patients [n=180] did not have previous experience of any sort of prosthesis. Although most of the patients preferred to have fixed partial denture [n=195] some of them responded that they would be comfortable with removable partial denture [n=33]. Low felt need was the most common reason among this study group for delay in seeking dental replacement, while 5% patients were in the post extraction healing period. Dentists were found to be the most important d riving force for patient awareness regarding replacement of teeth. Majority of the patients agreed that dental visits should be regular. Some patients [8.8%] did not appreciate the importance of restoring teeth while 62.5% of the patients had the perception that artificial teeth were not equivalent to natural teeth

Needs and demands of prosthetic treatment among two groups of individuals.

Objectives: The level of knowledge, awareness, and attitude about teeth-replacement options among a group of medical and paramedical subjects and to compare them with the general population. Materials and Methods: A self-administered questionnaires using simple Arabic language were distributed to two groups of subjects. Questions focused on the willingness to replace the missing teeth, the preferable methods of choice for replacement, and the reasons for these choices. The first group (G-I) was from the medical and paramedical staff who work in a military hospital at Jordan Royal medical services, the dental staff was excluded from the study. The other group (G-II) was from the general population who attended the dental department in the same hospital with comparable level of education. All the participants were partially edentulous excluding the third molars. Clinical examination was done by qualified prosthodontist to evaluate the possible prosthetic treatment options for replacement. A total of 612 questionnaires were distributed, of which 533 questionnaires were returned (response rate 87.09%). The results were analyzed and comparison was made between the two groups. Results: Responses to questions about awareness and attitude about prosthetic management of missing teeth revealed that G-I have more awareness than G-II to the probable causes for tooth/teeth replacement and limitation of the preferable method for replacement (P<0.05). More than 80% of the participants believed that replacement of anterior teeth is more important than the posterior teeth. Implants and fixed partial denture (FPD), respectively, were more preferable than removable prosthesis, although clinically was not indicated in cases (P<0.05). There was no clinical benefit from replacement of missing teeth in 33.4% while only 6% believe this. Conclusions: This study showed that the awareness and attitude between the medical and paramedical staff to prosthetic needs is better than between general populations. The demands for dental replacement by patients were significantly different when compared with the actual needs.
