Filter by: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 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
BACKGROUND: The literature has shown that simplified methods for complete denture fabrication can be as effective as the traditional techniques, but with less expenditure of time and resources, without prejudice to the patients. However, the effectiveness of these simplified methods for patients with more complex medical conditions haven't been deeply explored. OBJECTIVES: To evaluate the effectiveness of a proposed simplified method for complete dentures fabrication for patients with severely resorbed mandibular alveolar bones. METHOD: edentulous patients requesting treatment with bimaxillary complete dentures in a university clinic will be rehabilitated following a simplified technical proposal, being divided randomly into two groups according to the mandibular arch molding technique. In group A, a single impression with alginate through pre-fabricated trays will be performed, while patients allocated in group B will receive a second molding with a more complex technique. After 3 and 6 months, besides important clinical parameters, it will be investigated aspects related to patient's perceptions about the success of treatment. The study will be conducted with a minimum of 30 participants per group, and comparisons between the two groups will be made by means of tests suitable for distribution of data.
The purpose of this study is to examine the safety and usefulness of the Regenecure guided bone regeneration membrane for stimulating bone growth in patients that don't have enough bone for dental implant placement. The study will include 16 patients in each group, 20 non-smokers and 12 smokers, a total of 32 patients will participate in the study.
A potential complicating factor affecting implants is crestal bone loss. The causes of crestal bone loss are attributed to several factors. Among those hypothesized, proof for one or another cause remains obscure. Clinical documentation suggests that implant design may be a key factor. While the evidence is inconclusive, various authors suggest that it is a result of a combination of effects including (1) limited drilling procedure and restricted second-stage surgery 2, (2) rough implant surface in crestal bone 3, (3) microthread design for implant stiffness 4, (4) loading along a conus versus a flat interface 5, and (5) the absence of a significant microgap 6. The practice of platform switching (e.g. placing a 4 mm diameter abutment on a 5 mm implant seating surface physically moves the inflammatory cell infiltrate zone away from the crestal bone). The growing body of anecdotal platform switch evidence supports this biological width hypothesis. Here the biological width refers to the height of the dento-gingival attachment apparatus around a normal tooth and is defined as the distance necessary for a healthy existence of bone and soft tissue from the most apical extent of a dental restoration. To formally test this hypothesis the current study has been designed. The Prevail implant has been made with an integrated medialized seating surface that establishes a platform switching function. This implant moves the implant/abutment interface away from the crestal bone and may therefore reduce the amount of bone loss observed in the standard (non-medialized) Osseotite implant design. The objective of this study is to evaluate crestal bone levels adjacent to the implant reference point from the time of implant placement to a period of two years after loading.
Osseointegrated root form implants have been applied successfully in treating fully and partially edentulous patients and patients with single tooth missing. However, the success rate of osseointegrated dental implants was not as good in patients with poor bone quality. The reasons are believed that poor bone quality reduces the initial stability of dental implants and then reduces the success rate. For increasing initial stability of dental implants, some technical modifications are suggested in literature. However, due to lack of an objective method to evaluate bone quality, they are controversial. The purposes of this clinical study are to develop a standard procedure which using cutting resistance measured by Osseocare in surgery to evaluate the bone quality and to compare with the clinical experiences of oral surgeons. The objective outcome, initial stability of dental implant, is measured with Osstell. The analyzed results are also helpful for less experienced surgeons.
