View clinical trials related to Fractured Tooth.
Filter by:A total of 124 samples was calculated to be sufficient with G*power software ver 3.1.9.2 with effect size of 0.4 alpha probability error and power 0.95.With drop out estimate of 10% the final sample size decided was 140 samples. Patients reporting with complicated(pulp exposed or pulpally involved) horizontal crown root fracture with loss of crown structure in maxillary incisors and radiograph evidence of supra alveolar tooth structure are recruited for study. Informed consent from the patients or guardian as appropriate is obtained as suitable prior to treatment delivery. Exclusion criteria were:patients not willing for recall visits, root with evidence of cervical resorption or roor canal filling, open apices, patient with systemic ailments rendering root canal treatment, compromised periodontal health, vertical or horizontal root fracture. Pulpal condition of tooth was assessed using cold sensibility test(Neosnow, orikam health care Ltd, India.) amd confirmed upon access opening with teeth showing evidence of pulpal bleeding wad categorized as irreversible pulpitis and teeth with no evidence of pulpal bleeding categorized as necrotic pulp.
This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. Two adhesive resin cement techniques will be used to hold the crown to the tooth and they will be evaluated for creating sensitivity to the tooth. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.
Many techniques have been proposed to prevent or rather minimize the labial bone resorption following extraction including guided bone regeneration techniques that has been attempted for many years now to preserve the alveolar ridge dimensions . Immediate implant placement, flapless implant placement, palataly positioned implants and even platform switching. However none of these methods were able to completely preserve the coronal part of the facial bone wall, and since the main reason of bone loss following extraction is the loss of the periodontal ligament, it seemed logical that root retention may affect the resorption process,The reason the root retention technique works in its different applications is due to the maintenance of the periodontal attachment including cementum, periodontal ligaments and bundle bone, this principle was used by Hurzeler in 2010 in a technique called socket shied technique.

Total of 48 subjects were randomly assigned to treatment groups: UT Health Science Center at San Antonio Chi Mei Medical Center, Tainan, Taiwan Patients require a maxillary non-molar extraction site that is planned to be replaced by a dental implant and crown. This includes Straumann BL SLActive: Narrow (3.3mm) & Regular (4.1mm) Crossfit implants in all available lengths. Patients were randomly selected to receive either FDBA (test) or Autogenous bone + DBBM (control/standard) for contour augmentation.
