Filter by:The primary objective of this study is to determine if the use of a bone compaction process (osseodensification) (Densah™ bur: Versah Osseodensification Company™) to prepare dental implant sites, in human subjects, results in increased bone-ridge width, increased compact bone in the outer wall of the prepared sites, and dental implant stability.
The purpose of this study is to compare two barrier membrane products, Cytoplast (dPTFE) and BioXclude (human amnion chorion allograft), for their relative efficacies in dental socket preservation procedures, both when the socket is filled and overfilled with freeze dried bone allograft (FDBA).
The purpose of this non-inferiority trial is to determine the clinical efficacy of acellular dermal matrix (ADM) in the augmentation of the gum around dental implants as compared to an autologous gum graft (sCTG) obtained from the palate (roof of the mouth) in human adults. AlloDerm is regulated by the US Food and Drug Administration (FDA) as human tissue for transplantation. AlloDerm is processed and marketed in accordance with the FDA's requirements for banked human tissue (21 CFR, Part 1270 and Part 1271) and Standards for Tissue Banking of the American Association of Tissue Banks (AATB). Twenty adult subjects will be recruited who are in need of dental implant placement with simultaneous gum grafting to increase the thickness of the facial mucosa. Half of the subjects will be randomized to the ADM group and half will be randomized to the sCTG group. The surgical intervention will be performed according to the protocol and subjects will return for follow-up 2, 4, 8, and 16 weeks post-surgery for follow-up measurements of healing, gum thickness, subject perception of pain, and esthetic photographs.
Ultrasound activated pins have been used for the promotion of bone healing in combination with biodegradable membranes during bone grafting procedures. In the jaws, these pins have been successfully tested for both maxillary and mandibular ridge augmentaton. However, the usefulness of these pins in maxillary sinus lift procedures has not been tested. This study aims to use a bilateral split mouth design to compare the bone formation, healing and post-operative complications after the use of ultrasonic guided pins in a lateral window maxillary sinus augmentation procedure in comparison to lateral window maxillary sinus augmentation procedure procedure performed without the use of these pins.
Periodontitis is a highly prevalent chronic inflammatory disease that is characterized by loss of the periodontal ligament and alveolar bone, and is a major cause of tooth loss. Results from clinical and epidemiological studies have suggested that periodontitis and tooth loss are more prevalent in individuals with rheumatoid arthritis (RA). There is evidence to suggest that periodontitis could indeed be a causal factor in the initiation and maintenance of the autoimmune inflammatory response that occurs in RA. If so, chronic periodontitis might represent an important modifiable risk factor for RA. However, to date longitudinal studies on the effect of periodontitis on disease progression in RA are lacking. The aim of the present study is to assess the periodontal status of patients enrolled in an established longitudinal cohort of RA patients. These data will then be analysed to evaluate whether or not periodontal inflammation is related to parameters of rheumatoid arthritis.
BACKGROUND Tooth loss impairs the OHRQoL. Dental implants have expanded treatment options of edentulous patients and improved their OHRQoL, however, in the posterior maxillary sextants the possibility to place implants of desired length and diameter could be limited. lSFE and tSFE represent two surgical options to vertically enhance the available bone in the edentulous posterior maxilla. Invasivity, relevant postoperative discomfort, high costs, and long times needed for the finalization of the prosthetic rehabilitation, however, strongly limit the indications of lSFE and support the need for less traumatic procedures with similar clinical effectiveness and reduced morbidity. In 2008, the investigators proposed a user-friendly, safe, predictable and effective minimally-invasive procedure for tSFE, namely the Smart Lift technique. AIMS/OBJECTIVES The general aim of the present project is to validate the Smart Lift technique as a simplified and minimally-invasive procedure for the implant-supported rehabilitation of patients with edentulous, atrophic maxillary posterior sextants. METHODS In a multicenter RCT study design, the reconstructive (clinical) and patient-centered outcomes of tSFE performed according to the Smart Lift technique will be compared with those of conventional lSFE. EXPECTED RESULTS The Smart Lift technique should allow for a significant reduction of treatment time, post-surgery complications and costs and an increase in the satisfaction perceived by the edentulous patient with implant-supported rehabilitation, while maintaining a clinical efficacy as well as a similar or lower morbidity and discomfort when compared to lSFE. In other words, the investigators expect that more favorable risk-benefit and cost-utility ratio, as well as a better performance in terms of pain, comfort, physical, social and psychological effects of oral health, and issues concerning the OHRQoL, will be observed for the Smart Lift technique compared to lSFE.

The purpose of this study is to compare the success rates of two surgical protocols. One protocol will have the implants placed at the time of tooth extraction and placed into function. The other protocol will have the implants placed into healed extraction sites and placed into function.
The objective of this study is to investigate the safety and the function of the collagen Matrix 10808 in humans and to compare it versus the standard therapy, the transplantation of the autologous connective tissue graft. The Collagen Matrix was developed for soft tissue augmentation. It is a three dimensional porous Matrix and consists mainly of Collagen I and III. Study patients must have a single tooth gap with insufficient soft tissue volume after implant placement. Therefore a soft tissue augmentation will be necessary.
The purpose of this study is to determine whether fibre-reinforced composite resin restorations are effective for single tooth replacement, elimination of tooth mobility following periodontal treatment and as an orthodontic retainer.
