NCT ID: NCT01522365 Completed - Clinical trials for Partly Edentulous Maxilla

XiVE® CAD/CAM Bridges (Abutment-supported/ Implant-supported)

XiCC
Start date: October 7, 2010
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01421849 Withdrawn - Edentulous Clinical Trials

Mandibular Single Implant Overdenture: a Prospective Clinical Trial

Start date: August 2011
Phase: N/A
Study type: Interventional

Study hypothesis: that there would be no difference in patient satisfaction among institutionalised older people before and after treatment with a mandibular single implant-retained overdenture. In a preliminary phase, a new denture is made or the old denture is adapted to provide a well-fitting denture. Eight weeks after insertion of the new denture a single implant is placed in the centre of the mandibula. If the level of primary stability is sufficient to enable the implant to resist micromovement, the implant is immediately loaded . If not, the implant is loaded after 6 to 12 weeks. Primary stability is assessed by the final seating torque and by the clinician's interpretation and tactile sense of primary stability. Before, during and after the treatment patient satisfaction and clinical outcomes are evaluated by a 20 item questionnaire and a clinical examination.

NCT ID: NCT01420536 Completed - Edentulous Jaw Clinical Trials

Canine Guidance vs Bilateral Balanced Occlusion in Complete Denture

Start date: February 2009
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01411683 Completed - Edentulous Jaw Clinical Trials

Mandibular Overdentures Retained by Conventional or Mini Implants

Start date: September 2011
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01399775 Completed - Clinical trials for Alveolar Ridge Augmentation

Evaluation of Ridge Dimensional Changes After Immediate Implantation and Efficacy of This Procedure

Start date: May 2010
Phase: Phase 1/Phase 2
Study type: Interventional

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

NCT ID: NCT01392456 Completed - Clinical trials for Severe Atrophy of the Edentulous Mandible

Validation and Cross-Cultural Adaptation of the Romanian Version of Oral Health Impact Profile in Edentulous Adults

ROM-OHIP-ED
Start date: June 2004
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01308996 Withdrawn - Clinical trials for Edentulous Alveolar Ridge In Mandible

Clinical Study of INFUSE® Bone Graft Compared to Autogenous Bone Graft for Vertical Ridge Augmentation

Start date: April 2012
Phase: N/A
Study type: Interventional

The purpose of this study is to evaluate the INFUSE® Bone Graft as an alternative to autograft for bone formation in the back of the mandible (lower jaw) prior to placing dental implants.

NCT ID: NCT01230320 Completed - Edentulous Jaw Clinical Trials

Simplified vs. Conventional Methods for Complete Denture Fabrication

Start date: October 2010
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01191073 Completed - Clinical trials for Partially Edentulous Patients

Manually Versus Digitally Fabricated Removable Partial Dentures

Start date: June 2011
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT00922935 Completed - Jaw, Edentulous Clinical Trials

Comparison of Early and Late Loading in the Edentulous Upper Jaw Using Cresco Prosthetic System on Straumann Implants

Start date: October 2004
Phase: Phase 4
Study type: Interventional

Comparison of early and late loading of implants supporting full each prosthesis in upper jaw, using the Cresco prosthetic system on Straumann implants. The study hypothesis is that there is no difference between the bone loss (or gain) between the groups.
