Several recent systematic reviews have highlighted how the macrodesign of dental implants can influence stress distribution and biomechanical and biological behavior in implants immediately inserted in post-extraction sites. Finite element analyzes have confirmed the benefit of the inclination of the implant threads in reducing implant displacement in post-extraction sites, increasing primary stability, and decreasing stress in contact with the trabecular bone. Other comparative studies have shown that the design of the threads of the implant does not affect the distribution of stress in the surrounding bone. In view of the need to evaluate the influence of implant macrodesign in the case of implants inserted in post-extraction alveoli, this study will examine the clinical results of two different types of implants with different macrodesigns, with the aim of providing scientific evidence in this regard. The present study will investigate through a randomized controlled trial the effect of thread macrodesign of X-space implants on primary stability and osseointegration when inserted in post-extraction sites, as compared to cylindric 2P implants.
This study is a clinical trial to determine the retention and durability of the anterior zirconia wing bridge. The type of zirconia-wing bridge the investigators are researching in this study has two wings which generally have three countersunk holes (meaning that the circumference of the outer portion of the hole is larger than the inner part of the hole). Composite resin (dental filling material) is placed in the holes as well as under and around the wings. Twelve patients will have bridges placed and be evaluated every 6 months (ideally) to determine if the bridge is staying in place (retention) and if it is resistant to fracture (durability).
The primary aim of this study is to introduce a new effective and efficient 3D printed design of an intra-oral space maintainer. The secondary aim of the study is to: Evaluate the clinical performance of 3D printed space maintainer versus conventional metal band and loop over a period of 6 months regarding their functional , biological aspects and patient satisfaction.
Study the effect of neurectomy of nasopalatine nerve on the sensation of anterior palate in patients undergoing rehabilitation of anterior maxillary ridge with dental implant
Clinical trial to evaluate the success rate of autotransplantation of teeth with advanced or completed root growth with intraoperative extracorporeal root tip resection in 20 patients.
Comparison of different drilling speed to classify bone quality by tactile sensation on a saw bone model
Retrospective, observational cohort study. Objectives : To search for correlations between socio-economical deprivation and oral health in french children of 9 years of age. To study the annual use of oral and dental care of children from 6 to 9 years of age depending on their geographical and socio-economical environment, and the medical demography ; To identify and study the share of the cohort not using oral and dental care, and the socio-economical and geographical factors implicated in this non-use of care. The study will use data from the french nationwide healthcare systems database (SNDS) and data from the french national institute of statistics and economic studies (INSEE).
The interest in partial coverage retainers such as inlays and onlays have increased drastically because these restorations are able to provide a more conservative option requiring minimal tissue removal thus preserving healthy tooth structure to a maximum extent. If patient rejects an implant treatment and enough sound tooth structure is available it would be desirable to restore a missing tooth with Inlay-Retained Fixed Partial Denture instead of full coverage retained one . The use of all-ceramic materials for inlays and onlays in restorative dentistry is becoming more popular , the proper selection of restorative materials, careful preparation design and adequate adhesion between tooth/restorative material interfaces considered important factor to prevent failures . Zirconia was introduced into dentistry in the 1990s.The high initial strength and fracture toughness of zirconia results from a physical property of partially stabilized zirconia known as transformation toughening. On the other hand, its white color, similar to the color of natural teeth and its ability to transmit light makes it useful in aesthetically important areas . Inlay Fixed Partial Denture restoration may have increased the risk of fracture due to the relative small size of restorations compared to the complete coverage restoration. An unfavorable distribution of stresses between the ceramic inlay and tooth structure may result in marginal deterioration around the inlay or its failure. The direction of forces on the occlusal surface of Inlay Fixed Partial Denture may lead to the phenomenon of submargination, ceramic fracture, wear at interface and postoperative hypersensitivity which remain a problem that require further investigation. One of the most important factors in the success and longevity of a restoration is to have an accurate marginal fit. Ideally, the cemented restoration should precisely meet the finish line of the prepared tooth. In reality, clinical perfection is challenging to achieve and to verify.
This study follows subjects who have agreed with their dentist that their failing teeth or missing teeth all need replacing. This study follows their standard routine care with some additional assessments. The dental treatment option that replaces a whole arch or both arches (upper and lower jaws) of the mouth is call "Teeth in a Day" and information on the use of the JUVORA™ Dental Disc during this treatment is what is being collected as part of this study along with subjects follow-up care.
