Short-term quality of life change perceived by patients after transition to mandibular overdentures

Abstract The aim of this longitudinal observational study was to evaluate the oral health-related quality of life (OHRQoL) following patient rehabilitation with implant-retained mandibular overdentures (IMO) and to identify the contribution of the different domains to OHRQoL. The Oral Health Impact Profile (OHIP-EDENT), Dental Impact on Daily Living (DIDL), and Geriatric Oral Health Assessment Index (GOHAI) questionnaires were completed twice by 25 patients: after 3 months of rehabilitation with complete dentures (CD) and after 3 months of IMO loading using stud abutments. The evaluation after IMO rehabilitation showed significant improvement in three DIDL domains: appearance (p = 0.011), eating and chewing (p = 0.003), and general performance (p = 0.003). The GOHAI results showed significant differences in two domains: psychosocial (p = 0.005) and pain and discomfort (p = 0.0004). The OHIP-EDENT outcomes showed significant improvements in five domains: functional limitation (p = 0.0001), physical pain (p = 0.0002), physical disability (p = 0.0010), and psychological disability and handicap (p = 0.032). The largest observed effect sizes were close to one standard deviation and were observed in the eating and chewing domain (0.93) of the DIDL; the pain and discomfort domain (0.83) of the GOHAI, and the functional limitation (0.89), physical pain (1.02), physical disability (0.84) domains of the OHIP-EDENT. The percentage of satisfied patients increased in all domains. Self-reported OHRQoL of CD wearers was significantly improved after 3 months of treatment with IMO, especially concerning the functional and pain-related aspects.

comparative study between interim tooth-attached dentures and complete overdentures in case of retained mandibular canines

Prosthodontists frequently encounter patients who have completely edentulous upper jaws and partially edentulous lower jaws with retained mandibular canines. A clinical study was carried out to compare the effect of interim tooth - attached dentures and complete overdentures on the periodontium of the retained mandibular canines as abutment teeth. Twenty patients having only remaining mandibular canines were selected and classified into two equal groups. For group [I], maxillary complete conventional dentures and mandibular interim tooth- attached dentures were constructed. Maxillary complete conventional dentures and mandibular complete overdentures were made for group "II". The periodontium of the abutment teeth was tested immediately and six months after wearing the corresponding denture to evaluate and compare between the two tested types of dentures. The results showed that complete overdenture was more valuable and suitable than interim tooth- attached denture
