Temporomandibular custom hemijoint replacement prosthesis: prospective clinical and kinematic study.

Purpose: To evaluate the clinical and functional outcomes of a custom temporomandibular hemijoint fossa/eminence implant prosthesis.

Materials And Methods: This prospective cohort study enrolled patients with osteoarthritis of the temporomandibular joint. The primary study variables were pain experience, pain intensity, chewing ability, jaw opening, joint noise, and overall satisfaction of the surgical outcome at 3, 6, and 13 months after surgery.

Surgical and prosthetic rehabilitation of edentulous adult cleft palate patients by dental implants.

Adult patients who did not receive proper treatment for cleft palate are challenging for clinicians in terms of prosthetic rehabilitation. Moreover, during the late stages of adulthood when patients become edentulous, prosthetic reconstruction becomes even more challenging. This clinical report describes the prosthetic rehabilitation of 2 edentulous geriatric patients with unrepaired cleft palate by placement of dental implants after closure of the oronasal communications.

Surgical management of advanced osteoarthritis of the temporomandibular joint with metal fossa-eminence hemijoint replacement: 10-year retrospective study.

Purpose: To evaluate the surgical outcomes and clinical experience of the treatment of degenerative osteoarthritis of the temporomandibular joint with metal fossa-eminence hemijoint replacement.

Materials And Methods: A retrospective chart review showed 99 patients (94 females and 5 males) who underwent treatment of degenerative joint disease with hemijoint replacement surgery, including data on 141 operated joints (57 unilateral, and 42 bilateral). A visual analog scale (VAS) patient-response questionnaire with directives was mailed to the 99 patients.

Accuracy and precision of a method to study kinematics of the temporomandibular joint: combination of motion data and CT imaging.

The purpose of the study was to test the precision and accuracy of a method used to track selected landmarks during motion of the temporomandibular joint (TMJ). A precision phantom device was constructed and relative motions between two rigid bodies on the phantom device were measured using optoelectronic (OE) and electromagnetic (EM) motion tracking devices. The motion recordings were also combined with a 3D CT image for each type of motion tracking system (EM+CT and OE+CT) to mimic methods used in previous studies.

Kinematic assessment of the temporomandibular joint before and after partial metal fossa eminence replacement surgery: a prospective study.

Purpose: This study compared the functional kinematic outcome of the temporomandibular joint (TMJ) in patients with end-stage TMJ osteoarthritis before and after TMJ hemijoint replacement surgery.

Materials And Methods: Fourteen patients (15 joints), with a mean age of 46.1 years, undergoing metal fossa eminence hemijoint replacement surgery, participated in this study.

A method for quantifying condylar motion in patients with osteoarthritis using an electromagnetic tracking device and computed tomography imaging.

Purpose: The purpose of this study was to develop a method to accurately study the kinematic changes of the temporomandibular joint (TMJ) in patients treated with hemijoint implant reconstruction for dysfunction of advanced degenerative osteoarthritis.

Materials And Methods: Mandibular kinematic motion data and patient-specific computed tomography (CT) data were acquired. Patients were fitted with custom dental stents that were embedded with metal markers to link the mandibular kinematics data with the 3-dimensional TMJ CT images.

Kinematic study of the temporomandibular joint in normal subjects and patients following unilateral temporomandibular joint arthrotomy with metal fossa-eminence partial joint replacement.

Purpose: The primary purpose of this study is to quantify the kinematics of the temporomandibular joint (TMJ) in patients following unilateral TMJ arthrotomy with metal fossa-eminence partial joint replacement and compare them with TMJ kinematics of healthy individuals.

Materials And Methods: Fourteen healthy volunteers and 13 female surgical patients (minimum 4 years postoperative) participated in this study. An electromagnetic tracking device was used to record the kinematics of the mandible relative to temporal bone during opening-closing, protrusive, and lateral movements.

Analysis of death certification in patients with early stage oral cavity squamous cell carcinoma.

Purpose: Although patients with T1 oral cavity carcinoma have a generally good prognosis, there is a significant burden of patients that have locoregional recurrence and mortality from early stage disease. The aim of this study was to investigate the specific cause of death in patients with T1N0M0 oral cavity squamous cell carcinoma (OCSCC) by analysis of death certification.

Patients And Methods: Patients were identified with T1 OCSCC treated over a 15-year period between 1986 to 2001 from the Mayo Clinic Tumor Registry.
