Filter by:This study aims to compare the clinical performance of 4 mm short implants supporting cross-arch fixed reconstructions in the edentulous mandible either with a combination of two short implants as distal support and two implants of conventional length placed in the interforaminal region, or with a combination of four short implants as distal support and two interforaminal implants of conventional length.
The purpose of this study is to evaluate the clinical results of implant-retained mandibular overdentures in edentulous patients.
The purpose of this study is to investigate to what extent IOs improve the functionality of edentulous patients and changes in quality of life and overall patient satisfaction following treatment with IOs.
The aim of this study is to evaluate: Primary objective The primary objective of the present study is to evaluate the marginal bone level changes when partially edentulous patients, treated with implants, received a multiunits screw retained fixed dental prosthesis with a Co/Cr milled framework with an Internal or External connection. Secondary objective 1. Overall survival rate. 2. Soft tissue status by assessment of bleeding on probing (BoP) and probing pocket depth (PPD) at baseline and after 1,3,5 years. 3. Prosthetic survival rates including screw or abutment loosening, framework or veneer fractures.
The device under investigation is SYNERGOSS, a CE (European Community CE) marked device. Synergoss is a granulated bone graft intended for use in dental applications. It is composed of a ceramic composite of Hydroxihapatite and Tricalciumphosphate in granules, coated with a dedicated collagen coating (porcine origin), obtained by means of collagen crosslinking on the ceramic granule surface. The purpose of the study is to confirm the foreseen efficacy and tolerability of SYNERGOSS, a synthetic dental graft coated with collagen. For this observational study, we will enroll patients that already received a surgical intervention for sinus augmentation/ socket preservation by means of SYNERGOSS to maintain and regenerate bone before installation of endosseous titanium implants to support a fixed prosthesis. Patients will be enrolled just before they receive the surgery for the installation of endosseous titanium implants, about 24 weeks after the first surgery for the implant of SYNERGOSS. The primary hypothesis is to demonstrate that SYNERGOSS consistently obtains the foreseen clinical benefit as declared in the Technical File. The secondary hypothesis is to demonstrate that SYNERGOSS side effects and risks match those declared in the Technical File. The study design is a - National - Monocentric - Prospective: the participants are identified and then followed forward in time. - Observational: participants that have recently received the grafting with SYNERGIES as part of normal and foreseen clinical procedures are enrolled in the study when they receive surgery for titanium implant placement and observed over time, with no substantial intervention other than the foreseen clinical treatment
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by a single implant. The study hypothesis is that SIMO is more effective but more costly than the conventional denture, though this incremental cost is relatively low for the offered effectiveness in terms of clinical and patient-reported outcomes.
Edentulism is often associated with a negative psychosocial impact. The concept of prosthetic rehabilitation in which a prosthesis is supported by osseointegrated implants, was first introduced in the late 1960s by Brånemark et al. and offers an interesting alternative to removable prosthesis. However, for patients with a severely atrophic maxilla or mandible, cranial bone grafting of the jaw is required to increase bone width and height necessary for implant insertion. An active collaboration between the surgeons from the Oral and Maxillofacial Department and the prosthodontist from the Department of Dentistry has been established for continuous quality improvement of the concept of (immediate/delayed) implant loading in patients requiring cranial bone grafts to augment their severely atrophic jawbone. The investigators aim to develop a prospective database registering (immediate/delayed) implant loading data of all patients eligible according to the protocol. Patient demographics, surgical, dental, prosthetic and patient satisfaction parameters are collected during consecutive visits within the framework of routine practice. Development of a database registering immediate functional loading data secondary to cranial bone-grafting of a severely atrophic jaw, will provide more information about potential patient, surgical and prosthetic factors influencing long-term biological and mechanical stability, as well as patient satisfaction. Moreover, registration of those results could function as a measurement of quality of care, and could be used for sample size calculation for future large prospective trials.
The investigators aim to evaluate the biological and mechanical short- and long-term outcome of IL in partially or completely edentulous patients. Moreover, the investigators aim to detect potential influencing risk factors predicting undesirable prosthetic outcome.
Study to assess the performance of six short implants (ANKYLOS C/X 6.6 mm) in the edentulous maxilla supporting fixed full-arch bridges after 5 years in function.
The purpose of this study is to evaluate the effectiveness of a simplified technique of conventional dentures fabrication, comparing it to a traditional technique, by evaluating the impact of oral health on quality of life, satisfaction of individuals and chewing efficiency as well assessing the quality of prosthetics and TMD. Furthermore, the cost involved in the manufacture of dentures through technique simplified will be compared to the cost involved in the traditional technique.
