PURPOSE: This within-subject comparison tested the null hypothesis that there is no difference in patient satisfaction and oral health-related quality of life when an individual with an edentulous mandible is rehabilitated with a two-implant overdenture or a three-implant-supported fixed dental prosthesis. MATERIALS AND METHODS: Twelve subjects with an edentulous mandible or failing dentition were rehabilitated with the use of endosseous dental implants. Three implants were placed, and were immediately loaded with a provisional fixed prosthesis with minimal cantilever...

Background: One of the most common problems in edentulous patients is the low stability of lower dentures. The most effective method to overcome this problem is implant-supported overdentures. After placing an implant, for the process of osseointegration to be complete and successful, it is better that patients do not use their denture for few months. This may be nonconvenient for patient because they are unable to speak and eat properly. The aim of this study was to evaluate the effect of low level laser (LLL) and light-emitting diode (LED) photobiomodulation on implant stability as well as their effect on interleukin-1 beta (IL-1β) and prostaglandin E2 (PGE2) biomarkers around implant in lower anterior region (over denture)...

As the UK witnesses a decline in the number of edentulous adults, there is a simultaneous reduction in the number of cases available to undergraduate dental students for the teaching of complete dentures. When edentulous adults are unable to function with conventional complete dentures, particularly pertaining to the mandibular denture, an implant-supported mandibular overdenture has been evidenced as the gold standard for edentulous patients. The evidence in favour of mandibular implant-supported overdentures is one of the most robust evidence bases for any clinical treatment and similarly it has been shown that undergraduate students are equally as capable in the provision of implant-supported overdentures as experienced prosthodontists...
