Filter by:Loss of teeth leads to loss of function and lack of normal alveolar growth, along with unpleasant esthetics that hamper the psychosocial development of the young child. Traditionally, the management of single tooth loss in a young child is done by conservative means. The presence of large pulp chambers in incompletely mineralized immature teeth of children predisposes the pulp to loss of vitality in cases of complete coverage restorations . Hence, the clinician resorts to partial coverage prostheses such as Maryland Bridge, resin-bonded restorations, or removable prostheses in cases of multiple missing teeth. None of these treatment methods are completely satisfactory and have their drawbacks. Partial dentures are dependent on the child's compliance. They increase the rate of decay and may cause gingival disease leading to bone resorption. Furthermore, there is a need to refabricate a new prosthesis from time to time to compensate for craniofacial growth. Mini-screw implant placement in a young child would be an ideal method of treatment for the absence of teeth. They restore the function, preserve the alveolar bone, and give excellent esthetics, restoring the child's confidence and social acceptability. Parents are usually keen to get this treatment done as soon as offer the suggestion. To our knowledge, there is no previous study that compared the two techniques. The limited evidence shows that mini-screw implants supported pontics are useful transitional restorations for missing permanent maxillary incisors in children and adolescents; however, further well-designed clinical trials are needed in this regard. As a result, this study will be conducted to fill the gap of knowledge.
Clinical and Radiographic Evaluation of the Effect of Hyaluronic Acid Surface Treatment Versus Sandblasted Acid Etched on Stability of Delayed Dental Implant in Posterior Maxilla.
Tooth replacement is a significant issue in the World. Such replacement is considered important by patients to improve aesthetics, function and quality of life. Tooth replacement is therefore a significant issue. Resin-bonded bridges (RBBs) are conservative and cost-effective tooth replacement option that involves minimal tooth preparation and are secured in place with an adhesive cement by bonding to the outer enamel layer of the tooth. Clinical reports of these prostheses at the University of Hong Kong shows some of the highest success rate and greatest longevity in the dental literature. However, a problem with this type of prosthesis in that it still needs some tooth preparation to accommodate the framework thickness of the bridge. In some patients with tooth wear, this may mean cutting through the enamel crown down into dentine which will weaken the tooth. In light of the tooth preparation some patients will refuse this treatment, in particular patients with dental drill phobias. The aim of this study is to investigate RBBs with tooth preparation and with no tooth preparation for the replacement of single missing teeth in a randomized controlled trial. However, a significant consequence of a no preparation RBB will mean that after cementation the prosthesis will interfere with the patient's bite, making the bridge prosthesis stand high. This will take time for the patient's original occlusion to re-establish itself by the movement of the tooth supporting the bridge. Despite the success of "supra-occluding" restoration has been reported in some studies, currently neither no preparation nor supraoccluding dental bridges are the standard of care for general dental practitioners and have not been reported on as a clinical trial in the literature. Most symptoms reported for supraoccluding restorations were transient and are reversible. The findings of this research will have significant impact on the teaching and practice for clinical prosthodontics and patient care worldwide. Patients will have a dental prosthesis that requires no dental drilling, no local anaesthetic and will have a stronger tooth supporting the bridge that should have greater longevity. More patients, in particular phobic patients will therefore seek treatment for tooth replacement with this conservative treatment option.
