background radiography is as a part of periodontal examination. early detection of periodontal disease is important in the prevention of tooth loss and patient’s general health. objectives the objective of this study was to compare diagnostic accuracy of cone-beam computed tomography (cbct) with digital direct intraoral radiography, in assessment of periodontal osseous lesions. materials and me...

Mechanical stimuli are essential for the skeleton, and immobilization produces rapid bone loss in the weight-bearing bones (Peng et al. 1994). It is probable that a reduction of physical activity may also affect the involutional osteopenia seen in elderly people. Immobilization of a limb provides an experimental way to study mechanical influences on bone tissue without interfering with hormonal...

the biological interaction between the jaw bones and dental implant is fundamental for the long-term success of dental implant placement. nevertheless, the insufficient bone volume remains a major clinical problem, especially in case of immediate dental implant. using a canine model, the present study proves the regenerative potential of adipose- derived stem cells (adscs) to repair peri-implan...

This is an atypical case report of a 20-year-old male patient who suffered from unusual unilateral, gingival enlargement together with rapidly progressive alveolar bone loss. The enlarged gingiva completely covered his left posterior teeth in both arches. The patient was diagnosed with gingival fibromatosis and aggressive periodontitis based on the clinical, histological, and radiographic findi...

Various types of bone conduction hearing aids have been widely used for rehabilitation the last 30 years. Among them, recently launched Osia<sup>®</sup>2 system is a new active transcutaneous implant using piezoelectric effect. This can be expected to deliver more efficient sound transmission, overcome attenuation, and improve high-frequency than conventional passive aids, considere...

objective: vertical bone loss evaluations in the nobel biocare replace® select tapered tm implant system in the human after one-year loading time. materials and methods: this retrospective cross-sectional study was performed on 31 patients (14 men, 17 women; mean age, 60.39 years) receiving 170 implants (mean, 5.48 for each patient) of groovy and non-groovy designs in the nobel biocare replace®...

Importance. Superior semicircular canal dehiscence (SCD) is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A "two-hit" hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head ...

OBJECTIVE To evaluate the sound localization capabilities of patients with unilateral, profound sensorineural hearing loss who had been treated with either a bone-anchored hearing device (Baha BP100) or a TransEar 380-HF bone-conduction hearing device. STUDY DESIGN Nonrandomized, prospective study. SETTING Tertiary referral private practice. PATIENTS Patients with unilateral, profound senso...
