Active clinical trials for "Mouth, Edentulous"

The purpose of this study is to evaluate survival for ASTRA TECH Implant System, OsseoSpeed™ implants following immediate loading in extraction sockets versus immediate loading in healed ridges. Patients in need of single standing implants replacing teeth in the maxilla within zone 15-25 will be included and followed for 5 years. Primary objective is implant survival rate at 12 months.

The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior maxilla in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.

This study is a randomized clinical trial comparing the conventional method of recording occlusal vertical dimension using Willis gauge from the base of the nose to the base of the chin with the other method using vernier caliper for the length of the index finger to access the satisfaction level of edentulous patients acquiring complete dentures.

comparing immediate functionally loaded implants and immediate non functionally loaded implants in the posterior mandibular region on bases of bone density and bone loss evaluated by cone-beam computed tomography (CBCT).

Analyzing and comparing the retention, accuracy, EMG and patient satisfaction of maxillary complete denture base fabricated by conventional and rapid prototyping techniques.

This study is a comparison of implant placed and simultaneously grafted with either autogenous connective tissue or a connective tissue allograft. The objective is to determine the change in soft tissue thickness and determine if a better result is obtained with the autograft or the allograft. The hypothesis is that there will be no difference in soft tissue thickness over the implant between the autograft and the allograft technique.

The purpose of the study is to evaluate Astra Tech Dental Implant System, Fixture Osseospeed™, in patients with tooth loss in the posterior mandible in an early loading protocol. Primary objectives are implant stability, marginal bone adaptation and survival rate.

This study aimed to evaluate the oral stereognosis in completely edentulous patients with palatal tori. Oral stereognosis is tested using different test specimens in completely edentulous patients with maxillary tori and completely edentulous patients without maxillary tori.

With an aging population a prevalence of edentulous patients increased above 60 % among individuals aged ≥65 yr. Face mask ventilation of these edentulous patients is often difficult because of the inadequate fitting of the standard mask to the face. In addition, because of a reduction in muscle tone under general anesthesia, the air space in the oropharynx is reduced, and posterior displacement of the tongue, soft palate and epiglottis tend to close the airway. The laryngeal mask airway (LMA) provides a better alternative to the standard face mask if the facial contours of the patient are not suited to the standard face mask. It is more difficult to perform bag-mask ventilation in edentulous patients than in patients with intact dentition. The laryngeal mask airway (LMA) provides a better alternative to the standard face mask if the facial contours of the patient are not suited to the standard face mask. We aimed to compare the routinely used laryngeal mask airway in our clinic, the LMA Unique™ with the newly released LMA Supreme™ in edentulous elderly patients for the success in first attempt insertion, ease and time of insertion, and oropharyngeal leak pressure.

Purpose: To compare complete denture outcomes between conventional and digital denture fabrication processes. Participants: Sixteen edentulous adult patients in the University of North Carolina School of Dentistry Student Clinic who are seeking removable complete dentures. Procedures (methods): Two complete sets of dentures will be fabricated for each subject: one using the conventional process (A) and the other using a digital process (B). Variability will be assessed by the research team, the treating dental students, an independent prosthodontist, and the patients through quantitative measures. Case selection and results analysis will be evaluated with recognition of the Prosthodontic Diagnostic Index.
