NCT07080177
Teeth loss are usually associated with alterations of extraction sockets result in obviously absorbed alveolar ridges and are often accompanied with soft tissue atrophy such as narrow keratinized tissue and a shallow vestibule. Lack of peri-implant keratinized tissue is a potential risk to peri-implant diseases. Although the role of width of KM in maintaining peri-implant health is a controversial topic, the majority of high-level evidence has suggested that a minimum KM width (KMW) of 2 mm around the dental implants is critical to maintain peri-implant health and the long-term survival of dental implants.
NCT06178796
This study aims to evaluate the changes in the stability and bone-implant contact surface of implants of the same macro-design placed with particle grafting in the fresh extraction socket, without grafting, and placed in healed implant sites.
NCT06602154
In this split mouth study design, 34 orthodontic patients coming for fixed appliance treatment will be bonded with standard light-cure composite bonding material and intervention of Resin Modified Glass Ionomer Cement (RMGIC). Contralateral quadrants will be allocated randomly for either RMGIC or visible light-cure composite bonding in both upper and lower jaw. Quadrant 1: Randomly selected, contralateral upper and lower quadrants from central incisor to second premolar will be bonded with RMGIC bonding system. Quadrant 2: Randomly selected, contralateral quadrants from central incisor to second premolar will be bonded with visible light-cure composite bonding material. Allocation of diagonally opposite quadrants by either bonding system will be assigned randomly. Quadrants to be bonded with Resin-modified glass ionomer cement and light-cure composite bonding material will be switched from patient to patient to ensure randomization. This study is single blinded. The study investigators will not be blinded while the patient will be kept blinded. On the first visit, a specially designed consent form will be signed by the participant. Patient interaction for the purpose of study will only be for 1 hour duration while bonding of brackets. After six months amount and location of bond breakages will be evaluated from orthodontic record files. This study will help us evaluate bond strength of RMGIC as compared to light cure composite. RMGIC can also be considered as the choice of material for bonding in high risk caries patients.
NCT05495867
In this case-control study a bioactive implant surface was compared with traditional surfaced implants. Primary objectives: Test the implant stability in post-extractive sites, comparing traditional surfaced implants (MultiNeO CS, control group) to bioactive surfaced implants (NINA- MultiNeO NH, treatment group). Primary outcome endpoints were Implant stability, assessed through Implant stability quotient (ISQ) values and Marginal bone loss (MBL)
NCT04741594
Approximately 40 implants from patients seeking treatment at the University of Oklahoma, College of Dentistry will be recruited for this study. Osteotomies will be prepared using the osseodensification technique and implants will be placed immediately after. The implants will be from a single manufacturer (Roxolid® SLA® Bone Level Tapered; Straumann®, Institut Straumann AG, Basel, Switzerland). Volumetric analysis of alveolar ridge will be studied using intra-surgical direct measurements and CBCT imaging. A custom stent will be fabricated to standardize the clinical and radiographic measurements at 2mm, 3mm, and 4mm apical to the alveolar crest. Changes in peri-implant bone density will be analyzed on standardized periapical and bitewing radiographs, using the ImageJ software (National Institute of Health, Bethesda, Maryland, USA). Implant stability quotient (ISQ) values will be recorded with a resonance frequency analysis system (Osstell®, Gothenburg, Sweden). Calibrated examiners will assess implant survival and biological or restorative complications and failures. Sites will be evaluated throughout osseointegration and one year after final restoration is delivered.
NCT01347177
Adhesive bridges are becoming popular in patients with congenitally missing teeth and these are type of bridges that can be done with only minimal or with no preparation to replace the missing tooth/teeth. The best clinical gain is the minimal tooth preparation or no need for the removal of tooth substance. Treatment for this type of bridges does not usually require anaesthesia. In addition, adhesive bridges can provide reasonable aesthetical outcome with minimal cost and reduced chair time. The biggest issue is that high failure rate in the long term, and gray colour shining through the metal wing cemented onto the abutment tooth. This can compromise the aesthetical outcome. The aesthetical problem can be solved by the use of zirconia all ceramic material to construct the bridge.

Effect of Topical Application of Hyaluronic Acid on Stability of Immediate Loading Dental Implant in Posterior Maxilla
NCT04873635
Objective: The aim of this prospective study was to investigate the patient-reported outcome measures (PROMs) of implant-supported prostheses (ISP) among patients who had excised pathological jaw lesions. Material and Methods: Patients who met the inclusion/exclusion criteria in a dental teaching hospital were recruited. Data pertaining to sociodemographic factors, conditions requiring surgery, surgical procedures and related complications, and types of ISP were collected. Patients' expectation and satisfaction to the ISP including oral health, self-perceived appearance, speech, chewing ability, oral comfort and ease of cleaning were assessed using the visual analogue scale (VAS, 0-100) and global transitional scale/judgement (Likert scale). Data were analysed using t-test and chi-square tests at the significance level α=0.05.
NCT03029637
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.
