Filter by:Patients with an edentulous mandible restored with implants who have participated in the core study CR 04/07 will be recruited for this extension study. No further interventions will be made for this extension study other than a clinical follow-up examination and questionnaires. Patients will not receive an investigational treatment in this study. Patients will be followed at 5 to 10 years from the date of the original implant loading
This study aims to evaluate the treatment with single implant overdenture for the edentulous mandible. The investigators hypothesize that treatment with lower overdenture retained by a single implant appears to have satisfactory effectiveness as a treatment for patients with specific conditions (such as maladaptive patients), with the advantages of simplicity and greater immediate benefits when compared to the conventional full denture, improving the retention and stability of the denture and better oral-related quality of life.
The purpose of this study is to test two standard of care techniques of placing dental implants, and to compare how people's bones and gums respond to two different depths at which implants are placed.
This study has been designed in order to collect data with regards to the peri-implant tissue outcome of abutment-supported restoration and direct implant-fixed restoration. Therefore a small group of subjects with partly edentulous maxilla is selected to show that both techniques are efficient and safe and to show comparable peri-implant tissue outcome for both methods. At the time of impression forming for each centre treatment A (= abutment-supported XiVE® CAD/CAM supra-structure) and B (= direct implant-fixed XiVE® CAD/CAM supra-structure) is assigned to the left and right side of the maxilla by being randomized at the time of impression forming.
The objective of this study is to compare the canine guidance (CG) and bilateral balanced occlusion (BBO) on denture satisfaction and kinesiographic parameters of complete denture wearers, by means of a cross-over trial. Edentulous patients will receive new maxillary and mandibular complete dentures and, after the intraoral adjustments and adaptation period, will randomly receive a sequence of occlusal schemes: BBO followed by CG, or CG followed by BBO.
This study aims to compare mandibular overdentures retained either by mini or standard size implants as a treatment for edentulous adults, in terms of patient-reported satisfaction and oral health-related quality of life. We will also evaluate post surgical discomfort, the success rate of prostheses and implants in the long term, denture quality and costs.
1. Evaluation of dimensional changes in alveolar ridge following immediate implantation compared to delayed implantation 2. evaluation of the effect of gap dimensions between socket walls and dental implant in implant stability
The aim of the study is: 1. To validate the Romanian translation of OHIP-EDENT (Oral Health Impact Profile in Edentulous Adults), the short form of OHIP (Oral Health Impact Profile) developed by Allen and Locker for edentulous adults. The OHIP questionnaire is an efficient instrument for assessment of OHRQoL - Oral Health-Related Quality of Life. 2. To compare satisfaction of 69 fully mandibular edentulous patients rehabilitated with implant-supported overdentures with three different types of retention: Retentive Anchors, Magnets, Locator.
BACKGROUND: The fabrication of complete dentures traditionally involves a series of complex technical procedures. Those procedures include two impressions for each jaw, the registration of the relationship between the upper teeth and the patient's head and usually two appointments for tooth try-in. However, recent studies have questioned the real need for such complex procedures. Simplified methods could have similar results if compared with conventional ones, and dentures would be delivered faster and with lower costs. OBJECTIVES: This study aims to compare the effectiveness complete dentures fabricated with a simplified or conventional method. METHODS: Eighty edentulous patients who requested treatment by maxillary and mandibular complete denture in a public dental clinic inside the University of Sao Paulo - Ribeirão Preto Dental School will be randomly divided into two groups. Group S will receive new dentures fabricated by a simplified method, whereas Group C will received new dentures according to a conventional method. Participants will complete a questionnaire for denture satisfaction and the oral health-related quality of life, 3 and 6 months after treatment. At the same time, a specialist in dental prostheses will evaluate the quality of new dentures.
In the clinical trial, the Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) fabricated removable partial dentures (RPD's) are evaluated on casts and clinically compared with a traditional fabricated RPD for 50 consecutive patients. During 5 years the patients are in a follow-up program in order to judge long-term stability, loss of retention, fractures, … of both groups of dentures.
